(c) Provide and install one or more approved and operational natural gas detecting devices in accordance with section 908.10 of the New York city building code or section 28-315.2.3 of the code, as applicable, or, in the alternative for class B multiple dwellings, provide and install a line-operated zoned natural gas detecting system with central annunciation and central office tie-in for all public corridors and public spaces, pursuant to rules promulgated by the commissioner of buildings or by the commissioner in consultation with the department of buildings and the fire department;

Devices must also be periodically replaced upon expiration of its useful life, or if stolen, removed, missing, or rendered inoperable.

Natural gas detecting devices have been grouped together in this new law with some requirements for smoke and carbon monoxide detectors, including the requirement to post or provide a notice. Specifically, the law details that owners must do the following if natural gas detectors are required.

Owners must “provide to at least one adult occupant of such dwelling unit information relating to:

• (i) the risks posed by carbon monoxide poisoning and, if natural gas detecting devices are required to be installed in such dwelling unit by rules promulgated by the commissioner of buildings, the risks posed by natural gas leaks,
• (ii) the testing and maintenance of smoke detecting devices, carbon monoxide detecting devices and, if natural gas detecting devices are required to be installed in such dwelling unit by rules promulgated by the commissioner of buildings, natural gas detecting devices,
• (iii) what to do if such devices alert,
• (iv) the useful life of such devices,
• (v) the owner’s duty to replace such devices pursuant to article 312 of title 28 and
• (vi) the occupant’s duty to maintain and repair such devices that are battery-operated and within such occupant’s dwelling unit and replace any or all such devices within such dwelling unit that are stolen, removed, found missing or rendered inoperable during such occupant’s occupancy of such dwelling unit; provided that the information provided in accordance with this paragraph may include material that is distributed by the manufacturer or material prepared or approved by the department of buildings; except that this paragraph shall not apply to class B multiple dwellings or smoke detecting devices in private dwellings;”

Generally, residential requirements for smoke and carbon monoxide detectors are outlined here by HPD – we’ll let you know if this changes to include natural gas detectors. We’ll also share any sample notices to residents if and when they’re available from the department.

What’s Next?

The big due date for compliance is May 1, 2025. Owners and managers can start installation now to ensure all dwellings comply on or before this date. You may also be able to take advantage of various programs offered from ConEd and other providers.

There may be future details on enforcement here – whether or not violations will be issued for noncompliance, by which agency, and if any fines will accompany them. Stay tuned for updates.

We recommend connecting with your electrical contractor (depending on your needs and/or plans), and tracking installation for each dwelling unit. You can do this using the InCheck Mobile app (including pictures with dates and times saved), and Compliance Manager, tracking portfolio-wide completion to 100% before next May. Reach out to your Customer Success Manager to enable tracking and make sure you’re set for every required dwelling.
