The Fire Department has adopted a rule entitled “Apartment and Guest Room Identification and Directional Markings and Signs,” to set forth standards and requirements for the design and placement of entrance door room number markings for dwelling units (apartments, guest rooms and sleeping rooms) in Group R-1 and Group R-2 buildings and occupancies, and building lobby and building hallway corridor directional signs, which serve to assist emergency response personnel in locating such dwelling units when responding to fires, medical emergencies and other emergencies at the premises. All apartment buildings and hotels in New York City must comply with this new requirement for apartment door markings and other signs by March 30th of 2018, however, the first compliance dates for occupancies with multi-floor dwellings (duplex, triplex) units are much, much sooner – March 30, 2017
