103 - Egress from apartments.

§  103. Egress from apartments.  1. a. Except as provided in paragraph  b of this subdivision, there shall be at least one means of egress  from  each  apartment  on each and every story of such apartment, and a second  means of egress if the first means is not within  fifty  feet  of  every  living  room  in  such apartment on such story. When two means of egress  are required, they shall open from different rooms.    b. In any class A fireproof dwelling or section thereof erected  under  plans  filed  in  the department after September first, nineteen hundred  fifty-one, an apartment occupying parts of not  more  than  two  stories  shall  have  at least one means of egress. Such required means of egress  shall be not more than forty feet from any room  within  such  apartment  and  shall  open  directly  upon  a  public hall. Such public hall shall  provide access  to  at  least  two  fire-stairs.  Any  stair  within  an  apartment  shall be at least two feet six inches in width and a terminus  shall be not more than twenty feet from  the  door  which  provides  the  required  egress  to  a  public hall, provided, however, that such stair  within an apartment shall extend downwards or upwards to the story which  provides the required access to at least two fire-stairs.  In the  event  of  but  one such means of egress, and if the stair within the apartment  extends downwards to provide egress to a public hall, there shall  be  a  balcony  upon  the upper story of the apartment. If, however, such stair  extends upwards to provide egress to a public hall, the balcony shall be  located on the lower story of the apartment.  Such balcony shall provide  access from the apartment to a room of an  adjoining  apartment  on  the  same  story. Such balcony shall be constructed of incombustible material  and be capable of sustaining a load of at least eighty pounds per square  foot. Access to such balcony shall not be obstructed by sinks or kitchen  fixtures or in any other way, and shall be  maintained  unobstructed  at  all  times.  Bars,  gates,  grilles  or other obstructing devices on any  window or door giving access to or egress from  such  balcony  shall  be  unlawful.    2.   Except   as  otherwise  expressly  provided  in  paragraph  b  of  subdivision six of section one hundred two  for  certain  dwellings  six  stories  or  less  in  height,  at  least one fire-stair shall be within  seventy-five feet of at least one means of egress from each apartment on  each story thereof.    3. When any such fire-stair serving any apartment as a required  means  of  egress from the dwelling opens on the entrance story of the dwelling  exclusively into an entrance hall, no other fire-stair serving the  same  apartment  as a required means of egress from the dwelling shall open on  such story  exclusively  into  the  same  entrance  hall.  Any  required  fire-stair  not  opening on such story exclusively into an entrance hall  shall open on a street or in  a  yard,  court  or  passageway  affording  continuous,  safe  and  unobstructed  access  to  a street; but any such  required fire-stair serving any apartment as a means of egress from  the  dwelling  may  have a supplementary entrance into the same entrance hall  as that into which any other fire-stair serving the same apartment as  a  required means of egress from the dwelling opens exclusively.    4.  When any apartment occupies parts or all of three or more stories,  every stair within such apartment leading to the  third  or  any  higher  story of such apartment shall be enclosed with fireproof partitions with  a  fireproof  door and assembly with the door self-closing at the second  story landing of such stair and at every higher story landing from which  the stair continues upward within the apartment;  or  in  lieu  of  such  fireproof  partitions  and  doors at least two means of egress from such  apartment opening from different rooms shall be provided on  the  first,  third and alternate higher stories, if any, of such apartment.5.  No  means  of egress from any apartment shall open into any stair,  fire-stair or fire-tower required under the provisions of  this  section  except through a vestibule or public hall.
