HPD and DOB
Natural gas alarms (Local Law 157)
Apartments in buildings with gas need natural gas alarms by January 1, 2027, placed near the gas appliance.
The clock
When it comes due
- Required by January 1, 2027
- In the same room as the gas appliance, 3 to 10 feet from it
- Who it applies to
- Class A and Class B multiple dwellings with gas. An apartment with no gas appliance may still need one if it sits directly above gas piping or a gas appliance
- When
- By January 1, 2027. Local Law 102 of 2025 moved the date from May 1, 2025, and HPD’s October 2026 bulletin confirms January 1, 2027
- Who does it
- The owner installs the alarms and replaces them at the end of their useful life; the tenant maintains battery-operated alarms in the apartment
- Hard-wired alarms are installed by a New York City licensed electrical contractor; battery and plug-in alarms can be installed by others
- Alarms must be listed and labeled to UL 1484
- What happens next
- Where a gas appliance is in an apartment, the alarm goes in the same room, 3 to 10 feet from the appliance, measured horizontally. HPD enforces, and owners of Class A buildings post a notice about the devices, which can be combined with the smoke and carbon monoxide notice
What Stoop does
