504.1.1 Main Front Entrance

The main front entrance of a building is the entrance that is designed to serve as the primary means of ingress and egress to the building, and which is located on a side of the building that contains windows, emergency escape and rescue openings, outdoor building corridors or other building openings that serve to afford firefighters access to the upper floors of the building. Where a building has more than one entrance that is so designed and situated, the owner may designate one such entrance as the main front entrance of the building, provided, however, that if such entrance does not provide an appropriate location for firefighting operations, the commissioner may require that another entrance be designated the main front entrance.
