17921.6.  Except as provided in Sections 18930 and 18949.5, the
department shall prepare and adopt minimum standards regulating the
use and application of cellular concrete as it determines are
reasonably necessary for the protection of life and property.




17921.7.  (a) (1) The Legislature finds and declares all of the
following:
   (A) Acrylonitrile-butadiene-styrene ("ABS") drain, waste, and vent
plumbing pipe is used to drain or vent wastewater from kitchens,
bathrooms, washers, and plumbing fixtures found in the home. ABS pipe
is commonly used in residential construction, and ABS pipe has been
installed in the foundations and walls of thousands of single-family
homes, apartments, condominiums, and other residences throughout
California.
   (B) The American Society for Testing and Materials (ASTM) has
established specifications for the manufacture of ABS pipe, including
a requirement that ABS pipe be made from virgin plastic resin. These
specifications have been incorporated into the Uniform Plumbing Code
(UPC), which is applicable to all occupancies throughout the state
pursuant to subdivision (b) of Section 18938, a provision of the
California Building Standards Law (Part 2.5 (commencing with Section
18901)).
   (C) ABS pipe that does not meet ASTM requirements might, within a
period of a decade or less, crack and leak wastewater and sewage,
resulting in structural damage, vermin infestation, and severe health
hazards for residents or occupants of buildings in which defectively
manufactured ABS pipe has failed. One apparent cause of these
mechanical failures of ABS pipe has been the use of nonvirgin,
reprocessed plastic resin for the manufacture of ABS pipe.
   (D) The continued use of this nonvirgin, reprocessed plastic resin
by some ABS pipe manufacturers violates the requirements of the UPC
and is also in violation of the building standards established in
accordance with the California Building Standards Law. The problem of
the property damage inflicted on the public continues to worsen.
   (E) Thousands of California residents either already have, or
eventually will, experience serious damage to their homes,
apartments, and condominiums, as well as threats to their health and
safety, because of the substandard ABS pipe that has been installed,
in violation of building standards, in structures throughout the
state.
   (F) There are currently no statutes or regulations that apply to
the sale of defective plastic resin to ABS pipe manufacturers.
   (2) It is, therefore, the intent of the Legislature that both of
the following occur:
   (A) That a provision that addresses the important issues set forth
in paragraph (1) be added to the State Housing Law.
   (B) That the Department of Housing and Community Development
expeditiously implement the provisions of Chapter 413 of the Statutes
of 1993 that relate to this section.
   (b) On and after the effective date of the act that adds this
section, no person shall sell or offer for sale a plastic resin for
use in the manufacture of ABS DWV pipe that does not meet the
requirements of the listing pursuant to authority granted by
subdivision (e).
   (c) (1) Any and all plastic resin sold to an ABS DWV pipe
manufacturer for use in ABS DWV pipe shall contain a certification
that the plastic resin conforms to the requirements specified in the
listing pursuant to subdivision (e).
   (2) Any and all plastic resin sold to an ABS pipe manufacturer
shall be accompanied by a document indicating the name and address of
the manufacturer of that plastic resin, the date that the plastic
resin was purchased by the seller, and specifications of the chemical
and physical properties of the plastic resin. For a period of at
least 10 years from the date of the sale of this plastic resin, the
information required to be certified by this subdivision shall be
kept onsite at the ABS pipe manufacturing plant, and available for
inspection by the enforcement agency, at all times.
   (d) No ABS DWV pipe that contains plastic resin that does not meet
the requirements of the listing pursuant to subdivision (e) may be
sold or offered for sale, or installed in any structure that is
subject to this part.
   (e) The listing agencies, as approved by the department, shall
publish in each listing agreement with ABS DWV pipe manufacturers a
list of ABS resins and resin compounds used by that manufacturer and
approved for use by the listing agency. The approval of ABS resins
and resin compounds shall be based on nationally recognized
standards. The listing agencies shall consult with the affected
parties.



17921.9.  (a) The Legislature finds and declares all of the
following:
   (1) The deterioration of copper piping has become a serious
problem in various communities in the state.
   (2) Chlorinated polyvinyl chloride (CPVC) plastic piping has been
successfully used for many years in other states and in nations
around the globe, and has also been widely used, in accordance with
federal regulations, in mobilehome construction.
   (3) The Department of Community Development of the City of Colton,
acting pursuant to a good-faith belief that it was in compliance
with state regulations, approved the use of CPVC piping as an
alternative to copper piping in early 1993 when the department was
confronted with widespread deterioration of copper piping systems in
a tract in the western part of that city.
   (4) The retrofitting of homes in Colton with CPVC piping has been
successful.
   (b) It is, therefore, the intent of the Legislature in enacting
this section to allow the use of CPVC piping in building construction
in California as an alternate material under specified conditions.
   (c) Notwithstanding any other provision of law, the provisions of
the California Plumbing Code that do not authorize the use of CPVC
piping within California shall not apply to any local government that
permitted the use of CPVC piping for potable water systems within
its jurisdiction prior to January 1, 1996. Any local government that
permitted the use of CPVC piping for potable water systems within its
jurisdiction prior to January 1, 1996, shall require both of the
following:
   (1) That the CPVC piping to be used is listed as an approved
material in, and is installed in accordance with, the 1994 edition of
the Uniform Plumbing Code.
   (2) That all installations of CPVC strictly comply with the
interim flushing procedures and worker safety measures set forth in
subdivisions (d) and (e).
   (d) The following safe work practices shall be adhered to when
installing both CPVC and copper plumbing pipe in California after the
effective date of the act that adds this section:
   (1) (A) Employers shall provide education and training to inform
plumbers of risks, provide equipment and techniques to help reduce
exposures from plumbing pipe installation, foster safe work habits,
and post signs to warn against the drinking of preoccupancy water.
   (B) For purposes of this paragraph, "training" shall include
training in ladder safety, safe use of chain saws and wood-boring
tools, hazards associated with other construction trades, hazards
from molten solder and flux, and the potential hazards and safe use
of soldering tools and materials.
   (2) Cleaners shall be renamed as primers, include strong warnings
on the hazards of using primers as cleaners, and include dyes to
discourage use as cleaners.
   (3) Applicators and daubers shall be limited to small sizes.
   (4) Enclosed spaces shall be ventilated with portable fans when
installing CPVC pipe.
   (5) Protective impermeable gloves shall be utilized when
installing CPVC pipe.
   (6) Employers shall provide onsite portable eyewash stations for
all employees to allow for immediate flushing of eyes in the event of
splashing of hot flux.
   (7) Employers using acetylene torches shall ensure that the
acetylene tanks are regularly maintained and inspected in accordance
with applicable regulatory requirements. Fire extinguishers shall be
kept in close proximity to the workplace.
   (e) All of the following flushing procedures shall be adhered to
when installing CPVC pipe in California after the effective date of
the act that adds this section:
   (1) When plumbing is completed and ready for pressure testing,
each cold water and hot water tap shall be flushed starting with the
fixture (basin, sink, tub, or shower) closest to the water meter and
continuing with each successive fixture, moving toward the end of the
system. Flushing shall be continued for at least one minute or
longer until water appears clear at each fixture. This step may be
omitted if a jurisdiction requires the building inspector to test
each water system.
   (2) The system shall be kept filled with water for at least one
week and then flushed in accordance with the procedures set forth in
paragraph (1). The system shall be kept filled with water and not
drained.
   (3) Before the premises are occupied, the hot water heater shall
be turned on and the system shall be flushed once more. Commencing
with the fixture closest to the hot water heater, the hot water tap
shall be permitted to run until hot water is obtained. The time
required to get hot water in a specific tap shall be determined and
then the cold water tap at the same location shall be turned on for
the same period of time. This procedure shall be repeated for each
fixture in succession toward the end of the system.
   (f) Nothing in this section shall be construed to affect the
applicability of any existing law imposing liability on a
manufacturer, distributor, retailer, installer, or any other person
or entity under the laws of this state for liability.
   (g) This section shall not be operative after January 1, 1998.



17921.10.  (a) The standards proposed by the department pursuant to
Section 17921 may include voluntary best practice and mandatory
requirements related to environmentally preferable water using
devices and measures. The standards shall not unreasonably or
unnecessarily impact the ability of Californians to purchase or rent
affordable housing, as determined by taking account of the overall
benefit derived from the standards.
   (b) Nothing in this section shall in any way reduce the authority
of the State Energy Resources Conservation and Development Commission
to adopt standards and regulations or take other actions pursuant to
Division 15 (commencing with Section 25000) of the Public Resources
Code.


17922.  (a) Except as otherwise specifically provided by law, the
building standards adopted and submitted by the department for
approval pursuant to Chapter 4 (commencing with Section 18935) of
Part 2.5, and the other rules and regulations that are contained in
Title 24 of the California Code of Regulations, as adopted, amended,
or repealed from time to time pursuant to this chapter shall be
adopted by reference, except that the building standards and rules
and regulations shall include any additions or deletions made by the
department. The building standards and rules and regulations shall
impose substantially the same requirements as are contained in the
most recent editions of the following uniform industry codes as
adopted by the organizations specified:
   (1) The Uniform Housing Code of the International Conference of
Building Officials, except its definition of "substandard building."
   (2) The Uniform Building Code of the International Conference of
Building Officials.
   (3) The Uniform Plumbing Code of the International Association of
Plumbing and Mechanical Officials.
   (4) The Uniform Mechanical Code of the International Conference of
Building Officials and the International Association of Plumbing and
Mechanical Officials.
   (5) The National Electrical Code of the National Fire Protection
Association.
   (6) Appendix Chapter 1 of the Uniform Code for Building
Conservation of the International Conference of Building Officials.
   (b) In adopting building standards for approval pursuant to
Chapter 4 (commencing with Section 18935) of Part 2.5 for publication
in the California Building Standards Code and in adopting other
regulations, the department shall consider local conditions and any
amendments to the uniform codes referred to in this section. Except
as provided in Part 2.5 (commencing with Section 18901), in the
absence of adoption by regulation, the most recent editions of the
uniform codes referred to in this section shall be considered to be
adopted one year after the date of publication of the uniform codes.
   (c) Except as provided in Section 17959.5, local use zone
requirements, local fire zones, building setback, side and rear yard
requirements, and property line requirements are hereby specifically
and entirely reserved to the local jurisdictions notwithstanding any
requirements found or set forth in this part.
   (d) Regulations other than building standards which are adopted,
amended, or repealed by the department, and building standards
adopted and submitted by the department for approval pursuant to
Chapter 4 (commencing with Section 18935) of Part 2.5, governing
alteration and repair of existing buildings and moving of apartment
houses and dwellings shall permit the replacement, retention, and
extension of original materials and the continued use of original
methods of construction as long as the hotel, lodginghouse, motel,
apartment house, or dwelling, or portions thereof, or building and
structure accessory thereto, complies with the provisions published
in the California Building Standards Code and the other rules and
regulations of the department or alternative local standards adopted
pursuant to subdivision (b) of Section 13143.2 or Section 17958.5 and
does not become or continue to be a substandard building. Building
additions or alterations which increase the area, volume, or size of
an existing building, and foundations for apartment houses and
dwellings moved, shall comply with the requirements for new buildings
or structures specified in this part, or in building standards
published in the California Building Standards Code, or in the other
rules and regulations adopted pursuant to this part. However, the
additions and alterations shall not cause the building to exceed area
or height limitations applicable to new construction.
   (e) Regulations other than building standards which are adopted by
the department and building standards adopted and submitted by the
department for approval pursuant to Chapter 4 (commencing with
Section 18935) of Part 2.5 governing alteration and repair of
existing buildings shall permit the use of alternate materials,
appliances, installations, devices, arrangements, or methods of
construction if the material, appliance, installation, device,
arrangement, or method is, for the purpose intended, at least the
equivalent of that prescribed in this part, the building standards
published in the California Building Standards Code, and the rules
and regulations promulgated pursuant to the provisions of this part
in performance, safety, and for the protection of life and health.
Regulations governing abatement of substandard buildings shall permit
those conditions prescribed by Section 17920.3 which do not endanger
the life, limb, health, property, safety, or welfare of the public
or the occupant thereof.
   (f) A local enforcement agency may not prohibit the use of
materials, appliances, installations, devices, arrangements, or
methods of construction specifically permitted by the department to
be used in the alteration or repair of existing buildings, but those
materials, appliances, installations, devices, arrangements, or
methods of construction may be specifically prohibited by local
ordinance as provided pursuant to Section 17958.5.
   (g) A local ordinance may not permit any action or proceeding to
abate violations of regulations governing maintenance of existing
buildings, unless the building is a substandard building or the
violation is a misdemeanor.



17922.1.  Notwithstanding Section 17922, local agencies may modify
or change the requirements published in the State Building Standards
Code or contained in other regulations adopted by the department
pursuant to Section 17922 if they make a finding that temporary
housing is required for use in conjunction with a filed mining claim
on federally owned property located within the local jurisdiction and
that the modification or change would be in the public interest and
consistent with the intent of the so-called Federal Mining Act of
1872 (see 30 U.S.C., Sec. 22, et seq.), relating to the development
of mining resources of the United States.



17922.12.  (a) For the purposes of this section, "graywater" means
untreated wastewater that has not been contaminated by any toilet
discharge, has not been affected by infectious, contaminated, or
unhealthy bodily wastes, and does not present a threat from
contamination by unhealthful processing, manufacturing, or operating
wastes. "Graywater" includes wastewater from bathtubs, showers,
bathroom washbasins, clothes washing machines, and laundry tubs, but
does not include wastewater from kitchen sinks or dishwashers.
   (b) Notwithstanding Chapter 22 (commencing with Section 14875) of
Division 7 of the Water Code, at the next triennial building
standards rulemaking cycle that commences on or after January 1,
2009, the department shall adopt and submit for approval pursuant to
Chapter 4 (commencing with Section 18935) of Part 2.5 building
standards for the construction, installation, and alteration of
graywater systems for indoor and outdoor uses.
   (c) In adopting building standards under this section, the
department shall do all of the following:
   (1) Convene and consult a stakeholder's group that includes
members with expertise in public health, water quality, geology or
soils, residential plumbing, home building, and environmental
stewardship.
   (2) Ensure protection of water quality in accordance with
applicable provisions of state and federal water quality law.
   (3) Consider existing research available on the environmental
consequences to soil and groundwater of short-term and long-term
graywater use for irrigation purposes, including, but not limited to,
research sponsored by the Water Environment Research Foundation.
   (4) Consider graywater use impacts on human health.
   (5) Consider the circumstances under which the use of in-home
graywater treatment systems is recommended.
   (6) Consider the use and regulation of graywater in other
jurisdictions within the United States and in other nations.
   (d) The department may revise and update the standards adopted
under this section at any time, and the department shall reconsider
these standards at the next triennial rulemaking that commences after
their adoption.
   (e) The approval by the California Building Standards Commission
of the standards for graywater systems adopted under this section
shall terminate the authority of the Department of Water Resources to
adopt and update standards for the installation, construction, and
alteration of graywater systems in residential buildings pursuant to
Chapter 22 (commencing with Section 14875) of Division 7 of the Water
Code.



17922.2.  (a) Notwithstanding any other provisions of this part,
ordinances and programs adopted on or before January 1, 1993, that
contain standards to strengthen potentially hazardous buildings
pursuant to subdivision (b) of Section 8875.2 of the Government Code,
shall incorporate the building standards in Appendix Chapter 1 of
the Uniform Code for Building Conservation of the International
Conference of Building Officials published in the California Building
Standards Code, except for standards found by local ordinance to be
inapplicable based on local conditions, as defined in subdivision
(b), or based on an approved study pursuant to subdivision (c), or
both. Ordinances and programs shall be updated in a timely manner to
reflect changes in the model code, and more frequently if deemed
necessary by local jurisdictions.
   (b) For the purpose of subdivision (a), and notwithstanding the
meaning of "local conditions" as used elsewhere in this part and in
Part 2.5 (commencing with Section 18901), the term "local conditions"
shall be limited to those conditions that affect the implementation
of seismic strengthening standards on the following only:
   (1) The preservation of qualified historic structures as governed
by the State Historical Building Code (Part 2.7 (commencing with
Section 18950)).
   (2) Historic preservation programs, including, but not limited to,
the California Mainstreet Program.
   (3) The preservation of affordable housing.
   (c) Any ordinance or program adopted on or before January 1, 1993,
may include exceptions for local conditions not defined in
subdivision (b) if the jurisdiction has approved a study on or before
January 1, 1993, describing the effects of the exceptions. The study
shall include socioeconomic impacts, a seismic hazards assessment,
seismic retrofit cost comparisons, and earthquake damage estimates
for a major earthquake, including the differences in costs, deaths,
and injuries between full compliance with Appendix Chapter 1 of the
Uniform Code for Building Conservation or the Uniform Building Code
and the ordinance or program. No study shall be required pursuant to
this subdivision if the exceptions for local conditions not defined
in subdivision (b) result in standards or requirements that are more
stringent than those in Appendix Chapter 1 of the Uniform Code for
Building Conservation.
   (d) Ordinances and programs adopted pursuant to this section shall
conclusively be presumed to comply with the requirements of Chapter
173 of the Statutes of 1991.



17922.3.  Notwithstanding any other provision of law, a residential
structure that is moved into, or within, the jurisdiction of a local
agency or the department, shall not be treated, for the purposes of
Section 104 of the 1991 Edition of the Uniform Building Code, as a
new building or structure, but rather shall be treated, for the
purposes of this part, as subject to Section 17958.9.



17922.5.  Any state or local agency which issues building permits
shall require, as a condition of issuing any building permit where
the working conditions of the construction would require an employer
to obtain a permit from the Division of Occupational Safety and
Health pursuant to Chapter 6 (commencing with Section 6500) of Part 1
of Division 5 of the Labor Code, that proof be submitted showing
that the employer has received such a permit from the Division of
Occupational Safety and Health.
   An employer may apply for a building permit prior to receiving the
permit from the Division of Occupational Safety and Health.



17922.6.  (a) The Office of Noise Control in coordination with the
department shall adopt and submit building standards for approval
pursuant to Chapter 4 (commencing with Section 18934) of Part 2.5 of
this division and shall adopt, amend, and repeal rules and
regulations other than building standards which establish uniform
minimum noise insulation requirements for hotels, motels, apartment
houses, and dwellings other than detached single-family dwellings.
   (b) Such requirements shall be based on performance in order to
require compliance onsite where the hotel, motel, apartment house, or
dwelling other than a detached single-family dwelling, is located.
   (c) Such requirements shall be sufficient to protect persons
within the hotel, motel, apartment house, or dwelling other than a
detached single-family dwelling, from the effects of excessive noise,
including, but not limited to, hearing loss or impairment and
persistent interference with speech and sleep.
   (d) The provisions of this section, the building standards
published in the State Building Standards Code relating to noise
insulation, and the other rules and regulations adopted pursuant to
this section shall apply equally to those hotels, motels, apartment
houses, and dwellings other than detached single-family dwellings,
owned, operated, or maintained by any public entity. The department
shall enforce such building standards published in the State Building
Standards Code and such other rules and regulations with respect to
any such hotel, motel, apartment house, or dwelling other than a
detached single-family dwelling, which is not subject to the
jurisdiction of any local building department.
   (e) The provisions of this section, the building standards
published in the State Building Standards Code relating to noise
insulation, and the other rules and regulations adopted pursuant to
this section shall not apply to detached single-family dwellings.
   (f) Such other rules and regulations adopted by the Office of
Noise Control shall become operative six months after their date of
adoption.
   (g) Sections 17925, 17958, 17958.5, and 17958.7 shall not apply to
the provisions of this section.



17922.7.  (a) Except as otherwise provided in subdivisions (b) and
(c), the governing body of every city, county, city and county, and
public entity shall adopt ordinances or regulations imposing the same
requirements as are published in the State Building Standards Code
relating to noise insulation and as are contained in the other rules
and regulations adopted pursuant to Section 17922.6 within six months
after the date of publication in the State Building Standards Code
or the date of adoption of such other rules and regulations. The
building standards relating to noise insulation published in the
State Building Standards Code and the other rules and regulations
adopted pursuant to Section 17922.6 shall apply in any city, county,
city and county, or to any hotel, motel, apartment house, or dwelling
other than a detached single-family dwelling, which is owned,
operated, or maintained by any public entity, if the appropriate
governing body fails to adopt such ordinances or regulations within
six months after such date of publication or adoption.
   (b) In adopting such ordinances or regulations, the governing body
of any city, county, city and county, or public entity may make such
changes, modifications, or additions to the minimum requirements
contained in such building standards relating to noise insulation
published in the State Building Standards Code, or in the other rules
and regulations adopted pursuant to Section 17922.6, as such
governing body determines are reasonably necessary due to local
conditions. The governing body may also impose noise insulation
standards on a case by case basis on new single-family detached
dwellings, if the governing body determines that such standards are
necessary due to substantial noise generated by airports, roadways,
or commercial and industrial activities immediately surrounding or
adjacent to such proposed dwellings. Any local noise insulation
standards adopted for single-family detached dwellings shall not
exceed comparable standards for multifamily housing. The governing
body shall find that ordinances or regulations, adopted pursuant to
this subdivision, will require the dimunition of the noise levels
permitted by the building standards relating to noise insulation
published in the State Building Standards Code and in the other rules
and regulations adopted pursuant to Section 17922.6.
   (c) Prior to making such modifications, changes, or additions
pursuant to subdivision (b), the governing body shall make an express
finding that such modifications, changes, or additions are needed,
which finding shall be available as a public record. A copy of such
finding, together with the modification, change, or addition, shall
be filed with the Office of Noise Control.



17922.8.  The Office of Noise Control may appoint an advisory
committee to assist the office in reviewing and revising the noise
insulation standards previously adopted.



17922.9.  (a) The Legislature hereby finds and declares that the
provision of an adequate level of affordable housing, in and of
itself, is a fundamental responsibility of the state and that a
generally inadequate supply of decent, safe, and sanitary housing
affordable to persons of low and moderate income threatens orderly
community and regional development, including job creation,
attracting new private investment, and creating the physical,
economic, social, and environmental conditions to support continued
growth and security of all areas of the state.
   The Legislature further finds and declares that many rural
communities depend on mortgage financing available through the
Farmers Home Administration and that the continued construction of
affordable housing is a priority for the state. However, the
Legislature, in requiring waiver of certain local requirements
respecting adequacy of garages and carports and house size, does not
endorse the restrictive Farmers Home Administration regulations that
preclude financing of two-car garages and houses exceeding a maximum
size.
   The Legislature further finds and declares that inadequate housing
supplies have a negative impact on regional development and are,
therefore, a matter of statewide interest and concern.
   (b) Notwithstanding any local ordinance, charter provision, or
regulation to the contrary, if the applicant for a building permit
for construction of a qualifying residential structure submits with
the application a conditional loan commitment letter or letter of
intent to finance issued by the Farmers Home Administration of the
United States Department of Agriculture for the structure, the city,
county, or city and county issuing the building permit shall not
impose any requirement on the permit respecting the size or capacity
of any appurtenant garage or carport or house size which exceeds the
size or capacity that the Farmers Home Administration will finance
under its then applicable regulations and policies. "Qualifying
residential structure," as used in this section, means any
single-family or multifamily residential structure financed by the
Farmers Home Administration and which is restricted pursuant to
federal law to ownership or occupancy by households with incomes not
exceeding the income criteria for persons and families of low and
moderate income, as defined by Section 50093, or more restrictive
income criteria.
   (c) This section does not preclude a city, county, or city and
county from requiring the provision of one uncovered, paved parking
space located outside the required setback and outside the driveway
approach to the garage or covered parking space plus a garage or
covered parking space that does not exceed the size and capacity
allowed for Farmers Home Administration financing. However, this
setback requirement may not exceed the setbacks applicable to
single-family dwelling units in the same zoning district that have
two-car garages.



17923.  (a) The provisions of Section 17922 are not intended to
prevent the use of any material, appliance, installation, device,
arrangement, or method of construction not specifically prescribed by
this part, the building standards published in the State Building
Standards Code relating thereto, and the other rules and regulations
promulgated pursuant thereto, providing such alternate has been
approved. The department may approve any such alternate if it finds
that the proposed design is satisfactory and that the material,
appliance, installation, device, arrangement, method, or work offered
is, for the purpose intended, at least the equivalent of that
prescribed in this part, the building standards published in the
State Building Standards Code relating thereto, and the other rules
and regulations promulgated pursuant thereto in performance, safety,
and for the protection of life and health.
   (b) Whenever there is evidence that any material, appliance,
installation, device, arrangement, or method of construction does not
conform to the requirements of this part, the building standards
published in the State Building Standards Code relating thereto, and
the other rules and regulations promulgated pursuant thereto, or in
order to substantiate claims for alternates, the department may
require tests as proof of compliance to be made at the expense of the
owner or his agent.



17924.  Rules and regulations shall be promulgated pursuant to
Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3
of Title 2 of the Government Code, and no state department, officer,
board, agency, committee, or commission shall have power pursuant to
the provisions of this part to publish building standards, as defined
in Section 18909, but shall propose and submit those building
standards as deemed necessary to carry out the provisions of this
part for adoption and publishing pursuant to the provisions of Part
2.5 (commencing wi

17921.7.  (a) (1) The Legislature finds and declares all of the
following:
   (A) Acrylonitrile-butadiene-styrene ("ABS") drain, waste, and vent
plumbing pipe is used to drain or vent wastewater from kitchens,
bathrooms, washers, and plumbing fixtures found in the home. ABS pipe
is commonly used in residential construction, and ABS pipe has been
installed in the foundations and walls of thousands of single-family
homes, apartments, condominiums, and other residences throughout
California.
   (B) The American Society for Testing and Materials (ASTM) has
established specifications for the manufacture of ABS pipe, including
a requirement that ABS pipe be made from virgin plastic resin. These
specifications have been incorporated into the Uniform Plumbing Code
(UPC), which is applicable to all occupancies throughout the state
pursuant to subdivision (b) of Section 18938, a provision of the
California Building Standards Law (Part 2.5 (commencing with Section
18901)).
   (C) ABS pipe that does not meet ASTM requirements might, within a
period of a decade or less, crack and leak wastewater and sewage,
resulting in structural damage, vermin infestation, and severe health
hazards for residents or occupants of buildings in which defectively
manufactured ABS pipe has failed. One apparent cause of these
mechanical failures of ABS pipe has been the use of nonvirgin,
reprocessed plastic resin for the manufacture of ABS pipe.
   (D) The continued use of this nonvirgin, reprocessed plastic resin
by some ABS pipe manufacturers violates the requirements of the UPC
and is also in violation of the building standards established in
accordance with the California Building Standards Law. The problem of
the property damage inflicted on the public continues to worsen.
   (E) Thousands of California residents either already have, or
eventually will, experience serious damage to their homes,
apartments, and condominiums, as well as threats to their health and
safety, because of the substandard ABS pipe that has been installed,
in violation of building standards, in structures throughout the
state.
   (F) There are currently no statutes or regulations that apply to
the sale of defective plastic resin to ABS pipe manufacturers.
   (2) It is, therefore, the intent of the Legislature that both of
the following occur:
   (A) That a provision that addresses the important issues set forth
in paragraph (1) be added to the State Housing Law.
   (B) That the Department of Housing and Community Development
expeditiously implement the provisions of Chapter 413 of the Statutes
of 1993 that relate to this section.
   (b) On and after the effective date of the act that adds this
section, no person shall sell or offer for sale a plastic resin for
use in the manufacture of ABS DWV pipe that does not meet the
requirements of the listing pursuant to authority granted by
subdivision (e).
   (c) (1) Any and all plastic resin sold to an ABS DWV pipe
manufacturer for use in ABS DWV pipe shall contain a certification
that the plastic resin conforms to the requirements specified in the
listing pursuant to subdivision (e).
   (2) Any and all plastic resin sold to an ABS pipe manufacturer
shall be accompanied by a document indicating the name and address of
the manufacturer of that plastic resin, the date that the plastic
resin was purchased by the seller, and specifications of the chemical
and physical properties of the plastic resin. For a period of at
least 10 years from the date of the sale of this plastic resin, the
information required to be certified by this subdivision shall be
kept onsite at the ABS pipe manufacturing plant, and available for
inspection by the enforcement agency, at all times.
   (d) No ABS DWV pipe that contains plastic resin that does not meet
the requirements of the listing pursuant to subdivision (e) may be
sold or offered for sale, or installed in any structure that is
subject to this part.
   (e) The listing agencies, as approved by the department, shall
publish in each listing agreement with ABS DWV pipe manufacturers a
list of ABS resins and resin compounds used by that manufacturer and
approved for use by the listing agency. The approval of ABS resins
and resin compounds shall be based on nationally recognized
standards. The listing agencies shall consult with the affected
parties.



17921.9.  (a) The Legislature finds and declares all of the
following:
   (1) The deterioration of copper piping has become a serious
problem in various communities in the state.
   (2) Chlorinated polyvinyl chloride (CPVC) plastic piping has been
successfully used for many years in other states and in nations
around the globe, and has also been widely used, in accordance with
federal regulations, in mobilehome construction.
   (3) The Department of Community Development of the City of Colton,
acting pursuant to a good-faith belief that it was in compliance
with state regulations, approved the use of CPVC piping as an
alternative to copper piping in early 1993 when the department was
confronted with widespread deterioration of copper piping systems in
a tract in the western part of that city.
   (4) The retrofitting of homes in Colton with CPVC piping has been
successful.
   (b) It is, therefore, the intent of the Legislature in enacting
this section to allow the use of CPVC piping in building construction
in California as an alternate material under specified conditions.
   (c) Notwithstanding any other provision of law, the provisions of
the California Plumbing Code that do not authorize the use of CPVC
piping within California shall not apply to any local government that
permitted the use of CPVC piping for potable water systems within
its jurisdiction prior to January 1, 1996. Any local government that
permitted the use of CPVC piping for potable water systems within its
jurisdiction prior to January 1, 1996, shall require both of the
following:
   (1) That the CPVC piping to be used is listed as an approved
material in, and is installed in accordance with, the 1994 edition of
the Uniform Plumbing Code.
   (2) That all installations of CPVC strictly comply with the
interim flushing procedures and worker safety measures set forth in
subdivisions (d) and (e).
   (d) The following safe work practices shall be adhered to when
installing both CPVC and copper plumbing pipe in California after the
effective date of the act that adds this section:
   (1) (A) Employers shall provide education and training to inform
plumbers of risks, provide equipment and techniques to help reduce
exposures from plumbing pipe installation, foster safe work habits,
and post signs to warn against the drinking of preoccupancy water.
   (B) For purposes of this paragraph, "training" shall include
training in ladder safety, safe use of chain saws and wood-boring
tools, hazards associated with other construction trades, hazards
from molten solder and flux, and the potential hazards and safe use
of soldering tools and materials.
   (2) Cleaners shall be renamed as primers, include strong warnings
on the hazards of using primers as cleaners, and include dyes to
discourage use as cleaners.
   (3) Applicators and daubers shall be limited to small sizes.
   (4) Enclosed spaces shall be ventilated with portable fans when
installing CPVC pipe.
   (5) Protective impermeable gloves shall be utilized when
installing CPVC pipe.
   (6) Employers shall provide onsite portable eyewash stations for
all employees to allow for immediate flushing of eyes in the event of
splashing of hot flux.
   (7) Employers using acetylene torches shall ensure that the
acetylene tanks are regularly maintained and inspected in accordance
with applicable regulatory requirements. Fire extinguishers shall be
kept in close proximity to the workplace.
   (e) All of the following flushing procedures shall be adhered to
when installing CPVC pipe in California after the effective date of
the act that adds this section:
   (1) When plumbing is completed and ready for pressure testing,
each cold water and hot water tap shall be flushed starting with the
fixture (basin, sink, tub, or shower) closest to the water meter and
continuing with each successive fixture, moving toward the end of the
system. Flushing shall be continued for at least one minute or
longer until water appears clear at each fixture. This step may be
omitted if a jurisdiction requires the building inspector to test
each water system.
   (2) The system shall be kept filled with water for at least one
week and then flushed in accordance with the procedures set forth in
paragraph (1). The system shall be kept filled with water and not
drained.
   (3) Before the premises are occupied, the hot water heater shall
be turned on and the system shall be flushed once more. Commencing
with the fixture closest to the hot water heater, the hot water tap
shall be permitted to run until hot water is obtained. The time
required to get hot water in a specific tap shall be determined and
then the cold water tap at the same location shall be turned on for
the same period of time. This procedure shall be repeated for each
fixture in succession toward the end of the system.
   (f) Nothing in this section shall be construed to affect the
applicability of any existing law imposing liability on a
manufacturer, distributor, retailer, installer, or any other person
or entity under the laws of this state for liability.
   (g) This section shall not be operative after January 1, 1998.



17921.10.  (a) The standards proposed by the department pursuant to
Section 17921 may include voluntary best practice and mandatory
requirements related to environmentally preferable water using
devices and measures. The standards shall not unreasonably or
unnecessarily impact the ability of Californians to purchase or rent
affordable housing, as determined by taking account of the overall
benefit derived from the standards.
   (b) Nothing in this section shall in any way reduce the authority
of the State Energy Resources Conservation and Development Commission
to adopt standards and regulations or take other actions pursuant to
Division 15 (commencing with Section 25000) of the Public Resources
Code.


17922.  (a) Except as otherwise specifically provided by law, the
building standards adopted and submitted by the department for
approval pursuant to Chapter 4 (commencing with Section 18935) of
Part 2.5, and the other rules and regulations that are contained in
Title 24 of the California Code of Regulations, as adopted, amended,
or repealed from time to time pursuant to this chapter shall be
adopted by reference, except that the building standards and rules
and regulations shall include any additions or deletions made by the
department. The building standards and rules and regulations shall
impose substantially the same requirements as are contained in the
most recent editions of the following uniform industry codes as
adopted by the organizations specified:
   (1) The Uniform Housing Code of the International Conference of
Building Officials, except its definition of "substandard building."
   (2) The Uniform Building Code of the International Conference of

in the California Building Standards Code and in adopting other
regulations, the department shall consider local conditions and any
amendments to the uniform codes referred to in this section. Except
as provided in Part 2.5 (commencing with Section 18901), in the
absence of adoption by regulation, the most recent editions of the
uniform codes referred to in this section shall be considered to be
adopted one year after the date of publication of the uniform codes.
   (c) Except as provided in Section 17959.5, local use zone
requirements, local fire zones, building setback, side and rear yard
requirements, and property line requirements are hereby specifically
and entirely reserved to the local jurisdictions notwithstanding any
requirements found or set forth in this part.
   (d) Regulations other than building standards which are adopted,
amended, or repealed by the department, and building standards
adopted and submitted by the department for approval pursuant to
Chapter 4 (commencing with Section 18935) of Part 2.5, governing
alteration and repair of existing buildings and moving of apartment
houses and dwellings shall permit the replacement, retention, and
extension of original materials and the continued use of original
methods of construction as long as the hotel, lodginghouse, motel,
apartment house, or dwelling, or portions thereof, or building and
structure accessory thereto, complies with the provisions published
in the California Building Standards Code and the other rules and
regulations of the department or alternative local standards adopted
pursuant to subdivision (b) of Section 13143.2 or Section 17958.5 and
does not become or continue to be a substandard building. Building
additions or alterations which increase the area, volume, or size of
an existing building, and foundations for apartment houses and
dwellings moved, shall comply with the requirements for new buildings
or structures specified in this part, or in building standards
published in the California Building Standards Code, or in the other
rules and regulations adopted pursuant to this part. However, the
additions and alterations shall not cause the building to exceed area
or height limitations applicable to new construction.
   (e) Regulations other than building standards which are adopted by
the department and building standards adopted and submitted by the
department for approval pursuant to Chapter 4 (commencing with
Section 18935) of Part 2.5 governing alteration and repair of
existing buildings shall permit the use of alternate materials,
appliances, installations, devices, arrangements, or methods of
construction if the material, appliance, installation, device,
arrangement, or method is, for the purpose intended, at least the
equivalent of that prescribed in this part, the building standards
published in the California Building Standards Code, and the rules
and regulations promulgated pursuant to the provisions of this part
in performance, safety, and for the protection of life and health.
Regulations governing abatement of substandard buildings shall permit
those conditions prescribed by Section 17920.3 which do not endanger
the life, limb, health, property, safety, or welfare of the public
or the occupant thereof.
   (f) A local enforcement agency may not prohibit the use of
materials, appliances, installations, devices, arrangements, or
methods of construction specifically permitted by the department to
be used in the alteration or repair of existing buildings, but those
materials, appliances, installations, devices, arrangements, or
methods of construction may be specifically prohibited by local
ordinance as provided pursuant to Section 17958.5.
   (g) A local ordinance may not permit any action or proceeding to
abate violations of regulations governing maintenance of existing
buildings, unless the building is a substandard building or the
violation is a misdemeanor.



17922.1.  Notwithstanding Section 17922, local agencies may modify
or change the requirements published in the State Building Standards
Code or contained in other regulations adopted by the department
pursuant to Section 17922 if they make a finding that temporary
housing is required for use in conjunction with a filed mining claim
on federally owned property located within the local jurisdiction and
that the modification or change would be in the public interest and
consistent with the intent of the so-called Federal Mining Act of
1872 (see 30 U.S.C., Sec. 22, et seq.), relating to the development
of mining resources of the United States.



17922.12.  (a) For the purposes of this section, "graywater" means
untreated wastewater that has not been contaminated by any toilet
discharge, has not been affected by infectious, contaminated, or
unhealthy bodily wastes, and does not present a threat from
contamination by unhealthful processing, manufacturing, or operating
wastes. "Graywater" includes wastewater from bathtubs, showers,
bathroom washbasins, clothes washing machines, and laundry tubs, but
does not include wastewater from kitchen sinks or dishwashers.
   (b) Notwithstanding Chapter 22 (commencing with Section 14875) of
Division 7 of the Water Code, at the next triennial building
standards rulemaking cycle that commences on or after January 1,
2009, the department shall adopt and submit for approval pursuant to
Chapter 4 (commencing with Section 18935) of Part 2.5 building
standards for the construction, installation, and alteration of
graywater systems for indoor and outdoor uses.
   (c) In adopting building standards under this section, the
department shall do all of the following:
   (1) Convene and consult a stakeholder's group that includes
members with expertise in public health, water quality, geology or
soils, residential plumbing, home building, and environmental
stewardship.
   (2) Ensure protection of water quality in accordance with
applicable provisions of state and federal water quality law.
   (3) Consider existing research available on the environmental
consequences to soil and groundwater of short-term and long-term
graywater use for irrigation purposes, including, but not limited to,
research sponsored by the Water Environment Research Foundation.
   (4) Consider graywater use impacts on human health.
   (5) Consider the circumstances under which the use of in-home
graywater treatment systems is recommended.
   (6) Consider the use and regulation of graywater in other
jurisdictions within the United States and in other nations.
   (d) The department may revise and update the standards adopted
under this section at any time, and the department shall reconsider
these standards at the next triennial rulemaking that commences after
their adoption.
   (e) The approval by the California Building Standards Commission
of the standards for graywater systems adopted under this section
shall terminate the authority of the Department of Water Resources to
adopt and update standards for the installation, construction, and
alteration of graywater systems in residential buildings pursuant to
Chapter 22 (commencing with Section 14875) of Division 7 of the Water
Code.



17922.2.  (a) Notwithstanding any other provisions of this part,
ordinances and programs adopted on or before January 1, 1993, that
contain standards to strengthen potentially hazardous buildings
pursuant to subdivision (b) of Section 8875.2 of the Government Code,
shall incorporate the building standards in Appendix Chapter 1 of
the Uniform Code for Building Conservation of the International
Conference of Building Officials published in the California Building
Standards Code, except for standards found by local ordinance to be
inapplicable based on local conditions, as defined in subdivision
(b), or based on an approved study pursuant to subdivision (c), or
both. Ordinances and programs shall be updated in a timely manner to
reflect changes in the model code, and more frequently if deemed
necessary by local jurisdictions.
   (b) For the purpose of subdivision (a), and notwithstanding the
meaning of "local conditions" as used elsewhere in this part and in
Part 2.5 (commencing with Section 18901), the term "local conditions"
shall be limited to those conditions that affect the implementation
of seismic strengthening standards on the following only:
   (1) The preservation of qualified historic structures as governed
by the State Historical Building Code (Part 2.7 (commencing with
Section 18950)).
   (2) Historic preservation programs, including, but not limited to,
the California Mainstreet Program.
   (3) The preservation of affordable housing.
   (c) Any ordinance or program adopted on or before January 1, 1993,
may include exceptions for local conditions not defined in
subdivision (b) if the jurisdiction has approved a study on or before
January 1, 1993, describing the effects of the exceptions. The study
shall include socioeconomic impacts, a seismic hazards assessment,
seismic retrofit cost comparisons, and earthquake damage estimates
for a major earthquake, including the differences in costs, deaths,
and injuries between full compliance with Appendix Chapter 1 of the
Uniform Code for Building Conservation or the Uniform Building Code
and the ordinance or program. No study shall be required pursuant to
this subdivision if the exceptions for local conditions not defined
in subdivision (b) result in standards or requirements that are more
stringent than those in Appendix Chapter 1 of the Uniform Code for
Building Conservation.
   (d) Ordinances and programs adopted pursuant to this section shall
conclusively be presumed to comply with the requirements of Chapter
173 of the Statutes of 1991.



17922.3.  Notwithstanding any other provision of law, a residential
structure that is moved into, or within, the jurisdiction of a local
agency or the department, shall not be treated, for the purposes of
Section 104 of the 1991 Edition of the Uniform Building Code, as a
new building or structure, but rather shall be treated, for the
purposes of this part, as subject to Section 17958.9.



17922.5.  Any state or local agency which issues building permits
shall require, as a condition of issuing any building permit where
the working conditions of the construction would require an employer
to obtain a permit from the Division of Occupational Safety and
Health pursuant to Chapter 6 (commencing with Section 6500) of Part 1
of Division 5 of the Labor Code, that proof be submitted showing
that the employer has received such a permit from the Division of
Occupational Safety and Health.
   An employer may apply for a building permit prior to receiving the
permit from the Division of Occupational Safety and Health.



17922.6.  (a) The Office of Noise Control in coordination with the
department shall adopt and submit building standards for approval
pursuant to Chapter 4 (commencing with Section 18934) of Part 2.5 of
this division and shall adopt, amend, and repeal rules and
regulations other than building standards which establish uniform
minimum noise insulation requirements for hotels, motels, apartment
houses, and dwellings other than detached single-family dwellings.
   (b) Such requirements shall be based on performance in order to
require compliance onsite where the hotel, motel, apartment house, or
dwelling other than a detached single-family dwelling, is located.
   (c) Such requirements shall be sufficient to protect persons
within the hotel, motel, apartment house, or dwelling other than a
detached single-family dwelling, from the effects of excessive noise,
including, but not limited to, hearing loss or impairment and
persistent interference with speech and sleep.
   (d) The provisions of this section, the building standards
published in the State Building Standards Code relating to noise
insulation, and the other rules and regulations adopted pursuant to
this section shall apply equally to those hotels, motels, apartment
houses, and dwellings other than detached single-family dwellings,
owned, operated, or maintained by any public entity. The department
shall enforce such building standards published in the State Building
Standards Code and such other rules and regulations with respect to
any such hotel, motel, apartment house, or dwelling other than a
detached single-family dwelling, which is not subject to the
jurisdiction of any local building department.
   (e) The provisions of this section, the building standards
published in the State Building Standards Code relating to noise
insulation, and the other rules and regulations adopted pursuant to
this section shall not apply to detached single-family dwellings.
   (f) Such other rules and regulations adopted by the Office of
Noise Control shall become operative six months after their date of
adoption.
   (g) Sections 17925, 17958, 17958.5, and 17958.7 shall not apply to
the provisions of this section.



17922.7.  (a) Except as otherwise provided in subdivisions (b) and
(c), the governing body of every city, county, city and county, and
public entity shall adopt ordinances or regulations imposing the same
requirements as are published in the State Building Standards Code
relating to noise insulation and as are contained in the other rules
and regulations adopted pursuant to Section 17922.6 within six months
after the date of publication in the State Building Standards Code
or the date of adoption of such other rules and regulations. The
building standards relating to noise insulation published in the
State Building Standards Code and the other rules and regulations
adopted pursuant to Section 17922.6 shall apply in any city, county,
city and county, or to any hotel, motel, apartment house, or dwelling
other than a detached single-family dwelling, which is owned,
operated, or maintained by any public entity, if the appropriate
governing body fails to adopt such ordinances or regulations within
six months after such date of publication or adoption.
   (b) In adopting such ordinances or regulations, the governing body
of any city, county, city and county, or public entity may make such
changes, modifications, or additions to the minimum requirements
contained in such building standards relating to noise insulation
published in the State Building Standards Code, or in the other rules
and regulations adopted pursuant to Section 17922.6, as such
governing body determines are reasonably necessary due to local
conditions. The governing body may also impose noise insulation
standards on a case by case basis on new single-family detached
dwellings, if the governing body determines that such standards are
necessary due to substantial noise generated by airports, roadways,
or commercial and industrial activities immediately surrounding or
adjacent to such proposed dwellings. Any local noise insulation
standards adopted for single-family detached dwellings shall not
exceed comparable standards for multifamily housing. The governing
body shall find that ordinances or regulations, adopted pursuant to
this subdivision, will require the dimunition of the noise levels
permitted by the building standards relating to noise insulation
published in the State Building Standards Code and in the other rules
and regulations adopted pursuant to Section 17922.6.
   (c) Prior to making such modifications, changes, or additions
pursuant to subdivision (b), the governing body shall make an express
finding that such modifications, changes, or additions are needed,
which finding shall be available as a public record. A copy of such
finding, together with the modification, change, or addition, shall
be filed with the Office of Noise Control.



17922.8.  The Office of Noise Control may appoint an advisory
committee to assist the office in reviewing and revising the noise
insulation standards previously adopted.



17922.9.  (a) The Legislature hereby finds and declares that the
provision of an adequate level of affordable housing, in and of
itself, is a fundamental responsibility of the state and that a
generally inadequate supply of decent, safe, and sanitary housing
affordable to persons of low and moderate income threatens orderly
community and regional development, including job creation,
attracting new private investment, and creating the physical,
economic, social, and environmental conditions to support continued
growth and security of all areas of the state.
   The Legislature further finds and declares that many rural
communities depend on mortgage financing available through the
Farmers Home Administration and that the continued construction of
affordable housing is a priority for the state. However, the
Legislature, in requiring waiver of certain local requirements
respecting adequacy of garages and carports and house size, does not
endorse the restrictive Farmers Home Administration regulations that
preclude financing of two-car garages and houses exceeding a maximum
size.
   The Legislature further finds and declares that inadequate housing
supplies have a negative impact on regional development and are,
therefore, a matter of statewide interest and concern.
   (b) Notwithstanding any local ordinance, charter provision, or
regulation to the contrary, if the applicant for a building permit
for construction of a qualifying residential structure submits with
the application a conditional loan commitment letter or letter of
intent to finance issued by the Farmers Home Administration of the
United States Department of Agriculture for the structure, the city,
county, or city and county issuing the building permit shall not
impose any requirement on the permit respecting the size or capacity
of any appurtenant garage or carport or house size which exceeds the
size or capacity that the Farmers Home Administration will finance
under its then applicable regulations and policies. "Qualifying
residential structure," as used in this section, means any
single-family or multifamily residential structure financed by the
Farmers Home Administration and which is restricted pursuant to
federal law to ownership or occupancy by households with incomes not
exceeding the income criteria for persons and families of low and
moderate income, as defined by Section 50093, or more restrictive
income criteria.
   (c) This section does not preclude a city, county, or city and
county from requiring the provision of one uncovered, paved parking
space located outside the required setback and outside the driveway
approach to the garage or covered parking space plus a garage or
covered parking space that does not exceed the size and capacity
allowed for Farmers Home Administration financing. However, this
setback requirement may not exceed the setbacks applicable to
single-family dwelling units in the same zoning district that have
two-car garages.



17923.  (a) The provisions of Section 17922 are not intended to
prevent the use of any material, appliance, installation, device,
arrangement, or method of construction not specifically prescribed by
this part, the building standards published in the State Building
Standards Code relating thereto, and the other rules and regulations
promulgated pursuant thereto, providing such alternate has been
approved. The department may approve any such alternate if it finds
that the proposed design is satisfactory and that the material,
appliance, installation, device, arrangement, method, or work offered
is, for the purpose intended, at least the equivalent of that
prescribed in this part, the building standards published in the
State Building Standards Code relating thereto, and the other rules
and regulations promulgated pursuant thereto in performance, safety,
and for the protection of life and health.
   (b) Whenever there is evidence that any material, appliance,
installation, device, arrangement, or method of construction does not
conform to the requirements of this part, the building standards
published in the State Building Standards Code relating thereto, and
the other rules and regulations promulgated pursuant thereto, or in
order to substantiate claims for alternates, the department may
require tests as proof of compliance to be made at the expense of the
owner or his agent.



17924.  Rules and regulations shall be promulgated pursuant to
Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3
of Title 2 of the Government Code, and no state department, officer,
board, agency, committee, or commission shall have power pursuant to
the provisions of this part to publish building standards, as defined
in Section 18909, but shall propose and submit those building
standards as deemed necessary to carry out the provisions of this
part for adoption and publishing pursuant to the provisions of Part
2.5 (commencing wi

17921.7.  (a) (1) The Legislature finds and declares all of the
following:
   (A) Acrylonitrile-butadiene-styrene ("ABS") drain, waste, and vent
plumbing pipe is used to drain or vent wastewater from kitchens,
bathrooms, washers, and plumbing fixtures found in the home. ABS pipe
is commonly used in residential construction, and ABS pipe has been
installed in the foundations and walls of thousands of single-family
homes, apartments, condominiums, and other residences throughout
California.
   (B) The American Society for Testing and Materials (ASTM) has
established specifications for the manufacture of ABS pipe, including
a requirement that ABS pipe be made from virgin plastic resin. These
specifications have been incorporated into the Uniform Plumbing Code
(UPC), which is applicable to all occupancies throughout the state
pursuant to subdivision (b) of Section 18938, a provision of the
California Building Standards Law (Part 2.5 (commencing with Section
18901)).
   (C) ABS pipe that does not meet ASTM requirements might, within a
period of a decade or less, crack and leak wastewater and sewage,
resulting in structural damage, vermin infestation, and severe health
hazards for residents or occupants of buildings in which defectively
manufactured ABS pipe has failed. One apparent cause of these
mechanical failures of ABS pipe has been the use of nonvirgin,
reprocessed plastic resin for the manufacture of ABS pipe.
   (D) The continued use of this nonvirgin, reprocessed plastic resin
by some ABS pipe manufacturers violates the requirements of the UPC
and is also in violation of the building standards established in
accordance with the California Building Standards Law. The problem of
the property damage inflicted on the public continues to worsen.
   (E) Thousands of California residents either already have, or
eventually will, experience serious damage to their homes,
apartments, and condominiums, as well as threats to their health and
safety, because of the substandard ABS pipe that has been installed,
in violation of building standards, in structures throughout the
state.
   (F) There are currently no statutes or regulations that apply to
the sale of defective plastic resin to ABS pipe manufacturers.
   (2) It is, therefore, the intent of the Legislature that both of
the following occur:
   (A) That a provision that addresses the important issues set forth
in paragraph (1) be added to the State Housing Law.
   (B) That the Department of Housing and Community Development
expeditiously implement the provisions of Chapter 413 of the Statutes
of 1993 that relate to this section.
   (b) On and after the effective date of the act that adds this
section, no person shall sell or offer for sale a plastic resin for
use in the manufacture of ABS DWV pipe that does not meet the
requirements of the listing pursuant to authority granted by
subdivision (e).
   (c) (1) Any and all plastic resin sold to an ABS DWV pipe
manufacturer for use in ABS DWV pipe shall contain a certification
that the plastic resin conforms to the requirements specified in the
listing pursuant to subdivision (e).
   (2) Any and all plastic resin sold to an ABS pipe manufacturer
shall be accompanied by a document indicating the name and address of
the manufacturer of that plastic resin, the date that the plastic
resin was purchased by the seller, and specifications of the chemical
and physical properties of the plastic resin. For a period of at
least 10 years from the date of the sale of this plastic resin, the
information required to be certified by this subdivision shall be
kept onsite at the ABS pipe manufacturing plant, and available for
inspection by the enforcement agency, at all times.
   (d) No ABS DWV pipe that contains plastic resin that does not meet
the requirements of the listing pursuant to subdivision (e) may be
sold or offered for sale, or installed in any structure that is
subject to this part.
   (e) The listing agencies, as approved by the department, shall
publish in each listing agreement with ABS DWV pipe manufacturers a
list of ABS resins and resin compounds used by that manufacturer and
approved for use by the listing agency. The approval of ABS resins
and resin compounds shall be based on nationally recognized
standards. The listing agencies shall consult with the affected
parties.



17921.9.  (a) The Legislature finds and declares all of the
following:
   (1) The deterioration of copper piping has become a serious
problem in various communities in the state.
   (2) Chlorinated polyvinyl chloride (CPVC) plastic piping has been
successfully used for many years in other states and in nations
around the globe, and has also been widely used, in accordance with
federal regulations, in mobilehome construction.
   (3) The Department of Community Development of the City of Colton,
acting pursuant to a good-faith belief that it was in compliance
with state regulations, approved the use of CPVC piping as an
alternative to copper piping in early 1993 when the department was
confronted with widespread deterioration of copper piping systems in
a tract in the western part of that city.
   (4) The retrofitting of homes in Colton with CPVC piping has been
successful.
   (b) It is, therefore, the intent of the Legislature in enacting
this section to allow the use of CPVC piping in building construction
in California as an alternate material under specified conditions.
   (c) Notwithstanding any other provision of law, the provisions of
the California Plumbing Code that do not authorize the use of CPVC
piping within California shall not apply to any local government that
permitted the use of CPVC piping for potable water systems within
its jurisdiction prior to January 1, 1996. Any local government that
permitted the use of CPVC piping for potable water systems within its
jurisdiction prior to January 1, 1996, shall require both of the
following:
   (1) That the CPVC piping to be used is listed as an approved
material in, and is installed in accordance with, the 1994 edition of
the Uniform Plumbing Code.
   (2) That all installations of CPVC strictly comply with the
interim flushing procedures and worker safety measures set forth in
subdivisions (d) and (e).
   (d) The following safe work practices shall be adhered to when
installing both CPVC and copper plumbing pipe in California after the
effective date of the act that adds this section:
   (1) (A) Employers shall provide education and training to inform
plumbers of risks, provide equipment and techniques to help reduce
exposures from plumbing pipe installation, foster safe work habits,
and post signs to warn against the drinking of preoccupancy water.
   (B) For purposes of this paragraph, "training" shall include
training in ladder safety, safe use of chain saws and wood-boring
tools, hazards associated with other construction trades, hazards
from molten solder and flux, and the potential hazards and safe use
of soldering tools and materials.
   (2) Cleaners shall be renamed as primers, include strong warnings
on the hazards of using primers as cleaners, and include dyes to
discourage use as cleaners.
   (3) Applicators and daubers shall be limited to small sizes.
   (4) Enclosed spaces shall be ventilated with portable fans when
installing CPVC pipe.
   (5) Protective impermeable gloves shall be utilized when
installing CPVC pipe.
   (6) Employers shall provide onsite portable eyewash stations for
all employees to allow for immediate flushing of eyes in the event of
splashing of hot flux.
   (7) Employers using acetylene torches shall ensure that the
acetylene tanks are regularly maintained and inspected in accordance
with applicable regulatory requirements. Fire extinguishers shall be
kept in close proximity to the workplace.
   (e) All of the following flushing procedures shall be adhered to
when installing CPVC pipe in California after the effective date of
the act that adds this section:
   (1) When plumbing is completed and ready for pressure testing,
each cold water and hot water tap shall be flushed starting with the
fixture (basin, sink, tub, or shower) closest to the water meter and
continuing with each successive fixture, moving toward the end of the
system. Flushing shall be continued for at least one minute or
longer until water appears clear at each fixture. This step may be
omitted if a jurisdiction requires the building inspector to test
each water system.
   (2) The system shall be kept filled with water for at least one
week and then flushed in accordance with the procedures set forth in
paragraph (1). The system shall be kept filled with water and not
drained.
   (3) Before the premises are occupied, the hot water heater shall
be turned on and the system shall be flushed once more. Commencing
with the fixture closest to the hot water heater, the hot water tap
shall be permitted to run until hot water is obtained. The time
required to get hot water in a specific tap shall be determined and
then the cold water tap at the same location shall be turned on for
the same period of time. This procedure shall be repeated for each
fixture in succession toward the end of the system.
   (f) Nothing in this section shall be construed to affect the
applicability of any existing law imposing liability on a
manufacturer, distributor, retailer, installer, or any other person
or entity under the laws of this state for liability.
   (g) This section shall not be operative after January 1, 1998.



17921.10.  (a) The standards proposed by the department pursuant to
Section 17921 may include voluntary best practice and mandatory
requirements related to environmentally preferable water using
devices and measures. The standards shall not unreasonably or
unnecessarily impact the ability of Californians to purchase or rent
affordable housing, as determined by taking account of the overall
benefit derived from the standards.
   (b) Nothing in this section shall in any way reduce the authority
of the State Energy Resources Conservation and Development Commission
to adopt standards and regulations or take other actions pursuant to
Division 15 (commencing with Section 25000) of the Public Resources
Code.


17922.  (a) Except as otherwise specifically provided by law, the
building standards adopted and submitted by the department for
approval pursuant to Chapter 4 (commencing with Section 18935) of
Part 2.5, and the other rules and regulations that are contained in
Title 24 of the California Code of Regulations, as adopted, amended,
or repealed from time to time pursuant to this chapter shall be
adopted by reference, except that the building standards and rules
and regulations shall include any additions or deletions made by the
department. The building standards and rules and regulations shall
impose substantially the same requirements as are contained in the
most recent editions of the following uniform industry codes as
adopted by the organizations specified:
   (1) The Uniform Housing Code of the International Conference of
Building Officials, except its definition of "substandard building."
   (2) The Uniform Building Code of the International Conference of

Conservation of the International Conference of Building Officials.
   (b) In adopting building standards for approval pursuant to
Chapter 4 (commencing with Section 18935) of Part 2.5 for publication
in the California Building Standards Code and in adopting other
regulations, the department shall consider local conditions and any
amendments to the uniform codes referred to in this section. Except
as provided in Part 2.5 (commencing with Section 18901), in the
absence of adoption by regulation, the most recent editions of the
uniform codes referred to in this section shall be considered to be
adopted one year after the date of publication of the uniform codes.
   (c) Except as provided in Section 17959.5, local use zone
requirements, local fire zones, building setback, side and rear yard
requirements, and property line requirements are hereby specifically
and entirely reserved to the local jurisdictions notwithstanding any
requirements found or set forth in this part.
   (d) Regulations other than building standards which are adopted,
amended, or repealed by the department, and building standards
adopted and submitted by the department for approval pursuant to
Chapter 4 (commencing with Section 18935) of Part 2.5, governing
alteration and repair of existing buildings and moving of apartment
houses and dwellings shall permit the replacement, retention, and
extension of original materials and the continued use of original
methods of construction as long as the hotel, lodginghouse, motel,
apartment house, or dwelling, or portions thereof, or building and
structure accessory thereto, complies with the provisions published
in the California Building Standards Code and the other rules and
regulations of the department or alternative local standards adopted
pursuant to subdivision (b) of Section 13143.2 or Section 17958.5 and
does not become or continue to be a substandard building. Building
additions or alterations which increase the area, volume, or size of
an existing building, and foundations for apartment houses and
dwellings moved, shall comply with the requirements for new buildings
or structures specified in this part, or in building standards
published in the California Building Standards Code, or in the other
rules and regulations adopted pursuant to this part. However, the
additions and alterations shall not cause the building to exceed area
or height limitations applicable to new construction.
   (e) Regulations other than building standards which are adopted by
the department and building standards adopted and submitted by the
department for approval pursuant to Chapter 4 (commencing with
Section 18935) of Part 2.5 governing alteration and repair of
existing buildings shall permit the use of alternate materials,
appliances, installations, devices, arrangements, or methods of
construction if the material, appliance, installation, device,
arrangement, or method is, for the purpose intended, at least the
equivalent of that prescribed in this part, the building standards
published in the California Building Standards Code, and the rules
and regulations promulgated pursuant to the provisions of this part
in performance, safety, and for the protection of life and health.
Regulations governing abatement of substandard buildings shall permit
those conditions prescribed by Section 17920.3 which do not endanger
the life, limb, health, property, safety, or welfare of the public
or the occupant thereof.
   (f) A local enforcement agency may not prohibit the use of
materials, appliances, installations, devices, arrangements, or
methods of construction specifically permitted by the department to
be used in the alteration or repair of existing buildings, but those
materials, appliances, installations, devices, arrangements, or
methods of construction may be specifically prohibited by local
ordinance as provided pursuant to Section 17958.5.
   (g) A local ordinance may not permit any action or proceeding to
abate violations of regulations governing maintenance of existing
buildings, unless the building is a substandard building or the
violation is a misdemeanor.



17922.1.  Notwithstanding Section 17922, local agencies may modify
or change the requirements published in the State Building Standards
Code or contained in other regulations adopted by the department
pursuant to Section 17922 if they make a finding that temporary
housing is required for use in conjunction with a filed mining claim
on federally owned property located within the local jurisdiction and
that the modification or change would be in the public interest and
consistent with the intent of the so-called Federal Mining Act of
1872 (see 30 U.S.C., Sec. 22, et seq.), relating to the development
of mining resources of the United States.



17922.12.  (a) For the purposes of this section, "graywater" means
untreated wastewater that has not been contaminated by any toilet
discharge, has not been affected by infectious, contaminated, or
unhealthy bodily wastes, and does not present a threat from
contamination by unhealthful processing, manufacturing, or operating
wastes. "Graywater" includes wastewater from bathtubs, showers,
bathroom washbasins, clothes washing machines, and laundry tubs, but
does not include wastewater from kitchen sinks or dishwashers.
   (b) Notwithstanding Chapter 22 (commencing with Section 14875) of
Division 7 of the Water Code, at the next triennial building
standards rulemaking cycle that commences on or after January 1,
2009, the department shall adopt and submit for approval pursuant to
Chapter 4 (commencing with Section 18935) of Part 2.5 building
standards for the construction, installation, and alteration of
graywater systems for indoor and outdoor uses.
   (c) In adopting building standards under this section, the
department shall do all of the following:
   (1) Convene and consult a stakeholder's group that includes
members with expertise in public health, water quality, geology or
soils, residential plumbing, home building, and environmental
stewardship.
   (2) Ensure protection of water quality in accordance with
applicable provisions of state and federal water quality law.
   (3) Consider existing research available on the environmental
consequences to soil and groundwater of short-term and long-term
graywater use for irrigation purposes, including, but not limited to,
research sponsored by the Water Environment Research Foundation.
   (4) Consider graywater use impacts on human health.
   (5) Consider the circumstances under which the use of in-home
graywater treatment systems is recommended.
   (6) Consider the use and regulation of graywater in other
jurisdictions within the United States and in other nations.
   (d) The department may revise and update the standards adopted
under this section at any time, and the department shall reconsider
these standards at the next triennial rulemaking that commences after
their adoption.
   (e) The approval by the California Building Standards Commission
of the standards for graywater systems adopted under this section
shall terminate the authority of the Department of Water Resources to
adopt and update standards for the installation, construction, and
alteration of graywater systems in residential buildings pursuant to
Chapter 22 (commencing with Section 14875) of Division 7 of the Water
Code.



17922.2.  (a) Notwithstanding any other provisions of this part,
ordinances and programs adopted on or before January 1, 1993, that
contain standards to strengthen potentially hazardous buildings
pursuant to subdivision (b) of Section 8875.2 of the Government Code,
shall incorporate the building standards in Appendix Chapter 1 of
the Uniform Code for Building Conservation of the International
Conference of Building Officials published in the California Building
Standards Code, except for standards found by local ordinance to be
inapplicable based on local conditions, as defined in subdivision
(b), or based on an approved study pursuant to subdivision (c), or
both. Ordinances and programs shall be updated in a timely manner to
reflect changes in the model code, and more frequently if deemed
necessary by local jurisdictions.
   (b) For the purpose of subdivision (a), and notwithstanding the
meaning of "local conditions" as used elsewhere in this part and in
Part 2.5 (commencing with Section 18901), the term "local conditions"
shall be limited to those conditions that affect the implementation
of seismic strengthening standards on the following only:
   (1) The preservation of qualified historic structures as governed
by the State Historical Building Code (Part 2.7 (commencing with
Section 18950)).
   (2) Historic preservation programs, including, but not limited to,
the California Mainstreet Program.
   (3) The preservation of affordable housing.
   (c) Any ordinance or program adopted on or before January 1, 1993,
may include exceptions for local conditions not defined in
subdivision (b) if the jurisdiction has approved a study on or before
January 1, 1993, describing the effects of the exceptions. The study
shall include socioeconomic impacts, a seismic hazards assessment,
seismic retrofit cost comparisons, and earthquake damage estimates
for a major earthquake, including the differences in costs, deaths,
and injuries between full compliance with Appendix Chapter 1 of the
Uniform Code for Building Conservation or the Uniform Building Code
and the ordinance or program. No study shall be required pursuant to
this subdivision if the exceptions for local conditions not defined
in subdivision (b) result in standards or requirements that are more
stringent than those in Appendix Chapter 1 of the Uniform Code for
Building Conservation.
   (d) Ordinances and programs adopted pursuant to this section shall
conclusively be presumed to comply with the requirements of Chapter
173 of the Statutes of 1991.



17922.3.  Notwithstanding any other provision of law, a residential
structure that is moved into, or within, the jurisdiction of a local
agency or the department, shall not be treated, for the purposes of
Section 104 of the 1991 Edition of the Uniform Building Code, as a
new building or structure, but rather shall be treated, for the
purposes of this part, as subject to Section 17958.9.



17922.5.  Any state or local agency which issues building permits
shall require, as a condition of issuing any building permit where
the working conditions of the construction would require an employer
to obtain a permit from the Division of Occupational Safety and
Health pursuant to Chapter 6 (commencing with Section 6500) of Part 1
of Division 5 of the Labor Code, that proof be submitted showing
that the employer has received such a permit from the Division of
Occupational Safety and Health.
   An employer may apply for a building permit prior to receiving the
permit from the Division of Occupational Safety and Health.



17922.6.  (a) The Office of Noise Control in coordination with the
department shall adopt and submit building standards for approval
pursuant to Chapter 4 (commencing with Section 18934) of Part 2.5 of
this division and shall adopt, amend, and repeal rules and
regulations other than building standards which establish uniform
minimum noise insulation requirements for hotels, motels, apartment
houses, and dwellings other than detached single-family dwellings.
   (b) Such requirements shall be based on performance in order to
require compliance onsite where the hotel, motel, apartment house, or
dwelling other than a detached single-family dwelling, is located.
   (c) Such requirements shall be sufficient to protect persons
within the hotel, motel, apartment house, or dwelling other than a
detached single-family dwelling, from the effects of excessive noise,
including, but not limited to, hearing loss or impairment and
persistent interference with speech and sleep.
   (d) The provisions of this section, the building standards
published in the State Building Standards Code relating to noise
insulation, and the other rules and regulations adopted pursuant to
this section shall apply equally to those hotels, motels, apartment
houses, and dwellings other than detached single-family dwellings,
owned, operated, or maintained by any public entity. The department
shall enforce such building standards published in the State Building
Standards Code and such other rules and regulations with respect to
any such hotel, motel, apartment house, or dwelling other than a
detached single-family dwelling, which is not subject to the
jurisdiction of any local building department.
   (e) The provisions of this section, the building standards
published in the State Building Standards Code relating to noise
insulation, and the other rules and regulations adopted pursuant to
this section shall not apply to detached single-family dwellings.
   (f) Such other rules and regulations adopted by the Office of
Noise Control shall become operative six months after their date of
adoption.
   (g) Sections 17925, 17958, 17958.5, and 17958.7 shall not apply to
the provisions of this section.



17922.7.  (a) Except as otherwise provided in subdivisions (b) and
(c), the governing body of every city, county, city and county, and
public entity shall adopt ordinances or regulations imposing the same
requirements as are published in the State Building Standards Code
relating to noise insulation and as are contained in the other rules
and regulations adopted pursuant to Section 17922.6 within six months
after the date of publication in the State Building Standards Code
or the date of adoption of such other rules and regulations. The
building standards relating to noise insulation published in the
State Building Standards Code and the other rules and regulations
adopted pursuant to Section 17922.6 shall apply in any city, county,
city and county, or to any hotel, motel, apartment house, or dwelling
other than a detached single-family dwelling, which is owned,
operated, or maintained by any public entity, if the appropriate
governing body fails to adopt such ordinances or regulations within
six months after such date of publication or adoption.
   (b) In adopting such ordinances or regulations, the governing body
of any city, county, city and county, or public entity may make such
changes, modifications, or additions to the minimum requirements
contained in such building standards relating to noise insulation
published in the State Building Standards Code, or in the other rules
and regulations adopted pursuant to Section 17922.6, as such
governing body determines are reasonably necessary due to local
conditions. The governing body may also impose noise insulation
standards on a case by case basis on new single-family detached
dwellings, if the governing body determines that such standards are
necessary due to substantial noise generated by airports, roadways,
or commercial and industrial activities immediately surrounding or
adjacent to such proposed dwellings. Any local noise insulation
standards adopted for single-family detached dwellings shall not
exceed comparable standards for multifamily housing. The governing
body shall find that ordinances or regulations, adopted pursuant to
this subdivision, will require the dimunition of the noise levels
permitted by the building standards relating to noise insulation
published in the State Building Standards Code and in the other rules
and regulations adopted pursuant to Section 17922.6.
   (c) Prior to making such modifications, changes, or additions
pursuant to subdivision (b), the governing body shall make an express
finding that such modifications, changes, or additions are needed,
which finding shall be available as a public record. A copy of such
finding, together with the modification, change, or addition, shall
be filed with the Office of Noise Control.



17922.8.  The Office of Noise Control may appoint an advisory
committee to assist the office in reviewing and revising the noise
insulation standards previously adopted.



17922.9.  (a) The Legislature hereby finds and declares that the
provision of an adequate level of affordable housing, in and of
itself, is a fundamental responsibility of the state and that a
generally inadequate supply of decent, safe, and sanitary housing
affordable to persons of low and moderate income threatens orderly
community and regional development, including job creation,
attracting new private investment, and creating the physical,
economic, social, and environmental conditions to support continued
growth and security of all areas of the state.
   The Legislature further finds and declares that many rural
communities depend on mortgage financing available through the
Farmers Home Administration and that the continued construction of
affordable housing is a priority for the state. However, the
Legislature, in requiring waiver of certain local requirements
respecting adequacy of garages and carports and house size, does not
endorse the restrictive Farmers Home Administration regulations that
preclude financing of two-car garages and houses exceeding a maximum
size.
   The Legislature further finds and declares that inadequate housing
supplies have a negative impact on regional development and are,
therefore, a matter of statewide interest and concern.
   (b) Notwithstanding any local ordinance, charter provision, or
regulation to the contrary, if the applicant for a building permit
for construction of a qualifying residential structure submits with
the application a conditional loan commitment letter or letter of
intent to finance issued by the Farmers Home Administration of the
United States Department of Agriculture for the structure, the city,
county, or city and county issuing the building permit shall not
impose any requirement on the permit respecting the size or capacity
of any appurtenant garage or carport or house size which exceeds the
size or capacity that the Farmers Home Administration will finance
under its then applicable regulations and policies. "Qualifying
residential structure," as used in this section, means any
single-family or multifamily residential structure financed by the
Farmers Home Administration and which is restricted pursuant to
federal law to ownership or occupancy by households with incomes not
exceeding the income criteria for persons and families of low and
moderate income, as defined by Section 50093, or more restrictive
income criteria.
   (c) This section does not preclude a city, county, or city and
county from requiring the provision of one uncovered, paved parking
space located outside the required setback and outside the driveway
approach to the garage or covered parking space plus a garage or
covered parking space that does not exceed the size and capacity
allowed for Farmers Home Administration financing. However, this
setback requirement may not exceed the setbacks applicable to
single-family dwelling units in the same zoning district that have
two-car garages.



17923.  (a) The provisions of Section 17922 are not intended to
prevent the use of any material, appliance, installation, device,
arrangement, or method of construction not specifically prescribed by
this part, the building standards published in the State Building
Standards Code relating thereto, and the other rules and regulations
promulgated pursuant thereto, providing such alternate has been
approved. The department may approve any such alternate if it finds
that the proposed design is satisfactory and that the material,
appliance, installation, device, arrangement, method, or work offered
is, for the purpose intended, at least the equivalent of that
prescribed in this part, the building standards published in the
State Building Standards Code relating thereto, and the other rules
and regulations promulgated pursuant thereto in performance, safety,
and for the protection of life and health.
   (b) Whenever there is evidence that any material, appliance,
installation, device, arrangement, or method of construction does not
conform to the requirements of this part, the building standards
published in the State Building Standards Code relating thereto, and
the other rules and regulations promulgated pursuant thereto, or in
order to substantiate claims for alternates, the department may
require tests as proof of compliance to be made at the expense of the
owner or his agent.



17924.  Rules and regulations shall be promulgated pursuant to
Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3
of Title 2 of the Government Code, and no state department, officer,
board, agency, committee, or commission shall have power pursuant to
the provisions of this part to publish building standards, as defined
in Section 18909, but shall propose and submit those building
standards as deemed necessary to carry out the provisions of this
part for adoption and publishing pursuant to the provisions of Part
2.5 (commencing wi
