Property managers, landlords, and co-op boards in New York City are subject to rigorous municipal oversight by the Department of Housing Preservation and Development (HPD). Missing or improperly formatted building signs are among the most frequent citations issued during routine housing code inspections.
1. The Mandatory NYC HPD Signage Checklist
To maintain 100% compliance with the NYC Housing Maintenance Code, every residential building containing three or more dwelling units must prominently display the following five signs:
1. Building Registration Serial Number Plaque (§ 27-2098)
A rigid plaque posted in the building’s main entrance vestibule stating the official building registration serial number assigned by HPD. The plaque must measure at least 3” x 5” with high-contrast lettering at least 3/16” in height.
2. Superintendent / Janitor Identification Notice (§ 27-2053)
If the superintendent or managing agent does not reside on the premises, an approved sign must state the name, address, and 24-hour emergency telephone number of the superintendent or property management company.
3. Smoke Detector & Carbon Monoxide Alarm Notice (§ 27-2045)
A mandatory informational notice posted in the entrance hall informing residential tenants of their legal rights and obligations regarding smoke and carbon monoxide alarm testing and maintenance.
4. Key to Heating Plant & Boiler Room Notice (§ 27-2033)
A clear sign indicating the specific location on the premises where the emergency keys to the boiler room and central heating plant are kept.
5. Disaster Response & Emergency Evacuation Signage
A notice detailing building disaster preparedness procedures, emergency contacts, and evacuation routing posted in common residential hallways.
