2023 New York Laws › MDW - Multiple Dwelling › Article 5 - Non-Fireproof Multiple Dwellings › Title 1 - Fire Protection › 142 - Sub-Curb Uses.

§ 142. Sub-curb uses. 1. When such a dwelling is more than eighty feet
  in  height  measured from the lowest point of the yard or of any curb on
  which any part of the dwelling faces, whichever is lower, and  any  room
  in  such  dwelling below the level of the highest curb which any part of
  such dwelling faces is occupied for  living  purposes  as  permitted  in
  paragraph  f  of subdivision one of section thirty-four, the yard at the
  level of such highest curb shall be set back so as to be at least  eight
  feet  greater  in  depth  than the yard below such level unless the yard
  opens directly upon a street.
2. If such a dwelling is erected upon an interior lot running  through
  from street to street, the wall of the dwelling facing the lowest street
  shall,  at  the  level  of  the  highest  curb on which any part of such
  dwelling faces, be set back at least eight feet.
3. The setback of the yard  or  wall  required  by  each  of  the  two
  preceding subdivisions shall be a fire-terrace. Nothing herein contained
  shall  be  construed  to  permit  a yard of smaller dimensions below the
  level of such fire-terrace than required by paragraph f  of  subdivision

  curb  all structural members, partitions, furrings and ceilings shall be
  constructed of incombustible materials.

  additional  stair,  or  fire-stair, extending from the entrance story to
  the roof for each twenty rooms or fraction  thereof  on  such  story  or
  section thereof in excess of twenty, except that no additional stair, or
  fire-stair,  shall  be  required for such excess on any story or section
  thereof if the number of living rooms thereon does not exceed thirty and

  subdivision three, one means shall be to a public hall connecting with a
  stair,  fire-stair  or fire-tower, not more than fifty feet distant from
  such means. In dwellings erected under plans  filed  in  the  department
  after   September   first,   nineteen  hundred  fifty-one,  such  stair,
  fire-stair or fire-tower shall be enclosed. The other required means  of
  egress  shall  open  either directly upon a fire-escape or directly on a
  fire-tower balcony or a public vestibule or other public hall connecting
  with a stair, fire-stair or fire-tower balcony.
2. Except as hereinafter provided for dwellings two stories or less in
  height such balcony, vestibule, hall or stair shall  be  separated  from
  the  public  hall or stair on which the first means of egress opens by a
  fireproof wall, unpierced unless by an opening equipped with a fireproof
  door and assembly with the door self-closing. Such  door  shall  not  be
  held  open  by any device whatever. In a dwelling two stories or less in
  height, the separating wall may be fire-retarded on both sides  in  lieu
  of being fireproof.
