Apartment Marking Signs

Apartment marking signs are a critical part of New York City’s fire safety regulations. Under FDNY Rule 3 RCNY 505-01, all apartment doors in multiple dwellings must have durable, photoluminescent or retroreflective signs.These markings allow firefighters and emergency responders to quickly identify apartments in smoky, dark, or high-stress conditions, where visibility is limited. Clear identification saves precious seconds during rescues and evacuation efforts.
