2006 New York Code - Artificial Hall Lighting

 
    §  37.  Artificial  hall  lighting.  1. In every multiple dwelling the
  owner shall provide a light or lights, each  of  at  least  sixty  watts
  incandescent  or  twenty  watts  cool  white  fluorescent  or equivalent
  illumination, for every vestibule and  entrance  hall  in  every  public
  hall,  stair,  fire-stair  and  fire-tower on every floor. Said light or
  lights shall be located as prescribed by the department, but,  in  every
  stair,  fire-stair  or  fire-tower,  shall be so located that every part
  thereof shall be lighted.
    2. Except as provided in subdivision three, every such light shall  be
  turned  on  by the owner at sunset every day and shall not be turned off
  by the owner until the following sunrise. Every such light shall be kept
  burning daily from sunset until sunrise, but if it becomes  extinguished
  and  remains  so  without the knowledge or consent of the owner he shall
  not be liable. The burden shall be upon the owner to show that the light
  became and remained extinguished without his knowledge or consent.
    3. Every light in every fire-stair and fire-tower at every story,  and
  in  every  stair and public hall at every story where there is no window
  opening to the outer air, shall be kept burning continuously except that
  this provision shall not apply to public halls lighted  as  provided  in
  subdivision eleven of section two hundred seventeen.
    4. When the natural light in any public hall in a multiple dwelling is
  not  sufficient  to  permit  a person to read the names on a mail box or
  other receptacle for mail, the owner shall install  a  lighting  fixture
  directly over such mail box or receptacle and maintain it in serviceable
  condition,  so  that  a  light  may  be  turned  on  at any time for the
  convenience of tenants or the mail carrier.
