Local Law 157 of 2016 covers required natural gas detectors in NYC residential buildings. The DOB has finally approved rules outlining installation and location specifics following the release of the NFPA standard 715 in 2022. Here’s what you need to know:
What Is Local Law 157 of 2016?
Local Law 157 (linked here) requires installation of natural gas alarms in residential properties:
(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.
Details On The Final Rule
The rules clarifying requirements were initially proposed in 2023 with a comment period ending in November. Here’s what’s outlined in the final rule, published February 14th, 2024:

These were also impacted by commentary on the proposed rule. Here’s who can install these devices:

Natural gas alarms must be installed by a New York City Licensed electrical contractor, who obtains all required permits
- Exception: Natural gas alarms that are powered either by battery or by plug-in AC receptacle may be installed by other than a licensed electrical contractor, including but not limited to the building owner, building maintenance personnel, or the dwelling unit occupant.
- There are also some requirements related to electrical power – you can see the full details here, in the final rule.
- See attached PDFs for Sample Notices.
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.
