§ 60. Motor vehicle storage. A space may be provided and maintained in  any  multiple  dwelling or upon the premises thereof, or a structure may  be erected and maintained at the rear or side thereof, for  the  storage  of passenger motor vehicles but only with a written permit therefor when  required by local law and in accordance with every applicable local law,  ordinance,  resolution,  code  provision  or  regulation  and  with  the  following provisions:    1. a. It shall be unlawful to sell, store, handle or furnish gasoline,  oil or other fuel, or any article, accessory or service except  storage,  or  to  construct or maintain repair or grease pits in any such space or  structure. The provisions of this section shall not prevent the  keeping  of  such  gasoline, oil or other fuel as may be contained in the tank of  any such motor vehicle, and  the  cleaning  or  washing  of  such  motor  vehicles.    b.  Such  space  or  structure shall be used solely for the storage of  passenger motor vehicles of the occupants of the multiple dwelling or of  multiple dwellings under common ownership, except  that,  in  the  event  such  space  or structure or part thereof is not used by such occupants,  it may be rented by the owner or owners of such dwelling or dwellings to  persons other than the occupants thereof. The space which has thus  been  rented  shall  be made available to an occupant within thirty days after  written request therefor. Except as otherwise provided  in  paragraph  d  herein  transient  parking  for  any  period  of  less than one month by  non-occupants is unlawful. However, such space may be used also for  the  storage  of  any  type  of mechanical or motor-driven equipment or other  accessory device or passenger bus required for the proper maintenance of  the site and of the dwellings thereon.    c. If any of the provisions contained in paragraphs a and  b  of  this  subdivision  is violated, the department charged with the enforcement of  this chapter or the fire department shall order and direct that no motor  vehicle may be stored or kept in such space or structure thereafter  for  such  period  as  either  department  shall determine, and thereupon the  permit shall be suspended and no motor vehicle shall be stored  or  kept  in such space or structure for such period.    d.  A  city  may,  by  local law or ordinance, or the duly constituted  planning or appeal board or commission of a  city  may  by  granting  an  approval,  exception  or  variance,  authorize transient parking for any  period of less  than  one  month  of  motor  vehicles  in  dwellings  by  non-occupants  in  any  space that is not let to an occupant pursuant to  the other provisions of this section. Such city may  require  a  license  and  impose  a  fee therefor, and adopt supplementary rules, regulations  and conditions under which such parking shall be permitted.    2. a. Every such space or structure shall be designed and  constructed  to  accommodate  not  more  than  two  passenger motor vehicles for each  family in such multiple dwelling.    b. Such space  or  structure  shall  have  a  floor  area  within  its  enclosing  walls  not greater than three hundred square feet per vehicle  for each such family, including car parking spaces and aisles.    c.  Every  such  storage  space  or  structure  shall   be   fireproof  throughout, except that any extension of such storage space or structure  beyond  the  exterior  walls  of  a fireproof dwelling not exceeding one  story in height and  any  separate  structure  on  the  same  lot  as  a  fireproof   dwelling   may   be   of   uncombustible   material  with  a  fire-resistive rating of at  least  two  hours,  if  such  extension  or  separate  structure  complies with the provisions of paragraph e of this  subdivision.    d. When constructed within a  multiple  dwelling  such  storage  space  shall  be  equipped  with  a  sprinkler system and also with a system ofmechanical ventilation in no way connected with  any  other  ventilating  system.  Such storage space shall have no opening into any other part of  the dwelling except through a fireproof vestibule.  Any  such  vestibule  shall have a minimum superficial floor area of fifty square feet and its  maximum  area  shall  not  exceed  seventy-five square feet. It shall be  enclosed with incombustible partitions having a fire-resistive rating of  three hours.  The floor and ceiling of such vestibule shall also  be  of  incombustible  material having a fire-resistive rating of at least three  hours. There shall be two doors to provide access from the  dwelling  to  the car storage space. Each such door shall have a fire-resistive rating  of one and one-half hours and shall be provided with a device to prevent  the  opening of one door until the other door is entirely closed. One of  these doors shall swing into the vestibule from  the  dwelling  and  the  other  shall  swing  from  the vestibule into the car storage space. The  door from the vestibule to the dwelling shall be at  least  twenty  feet  distant  in  a  non-fireproof  dwelling  or  twelve  feet in a fireproof  dwelling from any stair enclosure, elevator shaft, or any opening to any  other vertical  shaft.  Such  vestibule  shall  also  be  equipped  with  sprinklers  and  with  an  exhaust duct having a minimum cross-sectional  area of one hundred forty-four square inches and shall not be  connected  with any other ventilating system.    e.  Such  storage space may be extended beyond the exterior walls of a  fireproof dwelling without any separating walls between its interior and  exterior portion  provided  that  such  extension  is  roofed  over  and  equipped with sprinklers throughout. Such extension shall be open to the  outer  air  on  at least two sides and in no event shall more than fifty  percent of its vertical surface area be enclosed in any manner. Any such  extension shall not be deemed to be a storage space  within  a  multiple  dwelling. Any enclosed sub-surface space beneath such an extension shall  however,  comply  with  all the provisions of this section applicable to  storage space within a multiple dwelling. Any portion of such  extension  of  storage  space  or of a separate structure for such storage purposes  appurtenant to a multiple dwelling which  face  any  dwelling  within  a  distance  of twenty feet therefrom or which is within thirty feet of any  living room window of any dwelling shall be unpierced  except  for  door  openings  for  vehicles.  A separate structure for such storage purposes  appurtenant to a multiple dwelling may  adjoin  such  dwelling  provided  that  the  part  of  the wall separating such space from the dwelling is  fireproof and unpierced, except by a fireproof vestibule as provided  in  subdivision  d. Such extension or separate structure shall be adequately  screened at grade level. That part of the roof of  an  extension  within  thirty  feet of any living room window of any dwelling shall not be used  for parking or storage of motor  vehicles  or  the  ingress  thereto  or  egress therefrom by motor vehicles.    f.  Any  such  structure  one  story  in  height or any extension of a  storage space within a multiple dwelling beyond  the  exterior  wall  of  such  dwelling where such extension is one story in height, shall not be  deemed an encroachment upon a yard or its equivalent  or  a  court.  Any  such  structure or extension in excess of such height shall be deemed an  encroachment thereupon.    g. In a completely enclosed  storage  structure  or  a  storage  space  within a multiple dwelling except for vehicle entrance doors, all doors,  windows  and their assemblies in the exterior walls of any such space or  structure accommodating more than five motor vehicles shall be fireproof  and such windows shall be either fixed windows or automatic fire windows  and glazed with wire glass. Any door or vehicle entrance to  such  space  or  structure  accommodating  more  than five motor vehicles shall be at  least twenty feet distant from any door giving access  to  any  requiredentrance  hall  from outside of the dwelling and shall be at least eight  feet distant from any other entrance or exit of such dwelling.  However,  in such space the windows in an exterior wall which faces the street may  be  of  incombustible  material and be glazed with plain glass, provided  that such windows are thirty feet or  more,  measured  in  a  horizontal  direction, from any opening in the exterior wall of the dwelling.    h.  Notwithstanding  any  other  provision  of  this section when such  storage space  or  structure  is  designed  and  constructed  within  or  appurtenant  to  a converted dwelling to accommodate not more than three  motor vehicles, (1) the ceiling  and  the  enclosing  walls  may  be  of  materials  having  a fire-resistive rating of not less than one hour and  the floors shall be fireproof; (2) only one opening shall  be  permitted  in  the enclosure partition between the garage and the dwelling and such  opening shall be protected by a fireproof door  and  assembly  with  the  door  self-closing;  (3)  a sprinkler system for such space shall not be  required; and (4) in lieu of mechanical ventilation, such space may have  fixed ventilation of not less than one  hundred  and  forty-four  square  inches for each motor vehicle.    3.  The  agency of a city authorized by law to make rules supplemental  to laws regulating construction, maintenance, use and area of  buildings  and  to grant variances of the zoning resolution shall have the power to  make rules to supplement the requirements of  this  section  and,  after  public  hearing,  may  grant  variances of local laws, resolutions, code  provisions or regulations which are more restrictive than the provisions  of this section, subject to such conditions as, in the opinion  of  such  agency,  will  best promote health, safety and welfare and carry out the  permissive intent of this section.  All  owners  of  property  within  a  radius  of one hundred fifty feet of the entrance or entrance passage to  such space or structure shall  be  duly  notified  of  any  such  public  hearing  and shall be given due opportunity to be heard thereon. Nothing  in this section shall be deemed to prohibit the use of a  part  of  such  lot  or plot as a parking area for the exclusive use of the occupants of  such dwelling.    4. No parking area or space to  be  used  for  the  storage  of  motor  vehicles  upon  the  premises of a multiple dwelling shall encroach upon  any part of the lot or plot which is required by any provision  of  this  chapter to be left open and unoccupied.    5.  None  of  the  provisions  of  this  section shall be construed as  permitting such space or structure or  part  thereof  to  be  rented  or  leased for the storage or warehousing of passenger or commercial type of  motor  vehicles,  which  are  part  of  stock  of  any  person,  firm or  corporation engaged in the  purchase,  sale  or  rental  of  such  motor  vehicles.
