N.Y. Multiple Dwelling Law § 104: Bulkheads

§ 104. Bulkheads. 1. Every stair, fire-stair and fire-tower required

by this chapter to extend to the level of the roof or to any terrace

formed by a setback shall extend to and through a fireproof bulkhead or

other fireproof enclosure in such roof or terrace approved by the

department. Such bulkhead or enclosure shall give unobstructed access

at all times to such roof or terrace by means of a fireproof door and

door assembly with the door self-closing. Such a door shall never be

self-locking and shall be fastened on the inside by movable bolts, hooks

or a lock which does not require a key to open from the inside of the

dwelling. Stairs to a bulkhead or enclosure shall have a handrail. When

a dwelling has a pitched or sloping roof with a pitch or slope of more

than fifteen degrees, no bulkhead or stair leading thereto shall be

required.

2. The roof of any penthouse may for the purpose of this section be

deemed part of the main roof if unobstructed access be provided and

maintained between all required fire-stair landings on the main roof

adjoining such penthouse, on the roof of such penthouse and on the roof

of any other penthouse extending above such main roof. Such unobstructed

access, where horizontal, shall be by means of a passage at least three

feet in clear width. It may include one or more stairs necessary to

provide access from any penthouse roof to any main roof adjoining such

penthouse. Such stairs shall conform to all the requirements of section

fifty-three for stairways of fire-escapes. There shall be a passageway

at least four feet in clear width between such stairs and the parapet

wall or guard railing of the main roof.
