N.Y. Comp. Codes R. & Regs. tit. 9, § 1506.1
(d) Motor vehicle storage facilities in or attached to a multiple dwelling shall be separated from such dwelling by construction having a fire resistance rating commensurate with the fire hazard involved. Such construction shall be continuous and unpierced by openings; except that openings shall be permitted therein when equipped with self-closing opening protectives having a fire resistance rating commensurate with the fire resistance rating of the separating construction, and when constructed in accordance with the requirements of this Part.
(e) Roof storage.
When motor vehicle storage facilities are provided on a roof, such roof shall be designed and constructed to support the resulting load; if such roof be the roof of a multiple dwelling, such dwelling shall be of fireproof construction.
(f) Roof storage parapet wall.
Roofs used for the storage of motor vehicles shall be provided with a noncombustible parapet wall at least 24 inches high. Such wall shall be designed to resist a lateral horizontal force of 300 pounds per linear foot, applied 21 inches above the level of the roof. If a substantial eight-inch high curb is provided at least four feet from the parapet wall, such wall need only be designed to resist a lateral horizontal force of 150 pounds per linear foot. When the parapet wall is less than 42 inches high, a railing capable of resisting a lateral horizontal force of 100 pounds per linear foot applied at the top rail shall be attached thereto. Such railing shall have a height of at least 42 inches above the roof level and any opening therein shall not exceed eight inches in at least one dimension.
(g) Parking decks and open sides.
Where a side of a motor vehicle storage facility is not enclosed, such side shall be protected with a noncombustible wall at each floor level at least 24 inches in height. Such wall shall be designed to resist a lateral horizontal force of 300 pounds per linear foot, applied 21 inches above the floor level. When an eight-inch curb is provided at least four feet from the wall, such wall need only be designed to resist a lateral force of 150 pounds per linear foot. When the height of such wall above the floor level is less than 42 inches, a railing capable of resisting a lateral horizontal force of 100 pounds per linear foot applied at the top rail shall be attached thereto. Such railing shall have a height of at least 42 inches above the floor level and any opening therein shall not exceed eight inches in width and four feet in length.
(h) Open storage.
Motor vehicles stored in the open upon the premises of a multiple dwelling shall not be stored within five feet of a combustible wall or wall opening of that multiple dwelling, except when such wall is protected to a height of at least eight feet on the side nearest such storage by a noncombustible facing of at least three-quarter hour fire protection, and such openings are equipped with opening protectives having a fire resistance rating of at least three-quarter hour.
