Local Law 157 of 2016 amended the New York City Housing Maintenance Code and the New York City Building Code to require the installation of natural gas detecting devices in residential buildings. It required the Department to promulgate a rule regarding the installation and location of natural gas alarms after an industry standard had been established. The rule was promulgated on March 15, 2024 and required installation of natural gas detecting devices on or before May 1, 2025. Local Law 102 of 2025 extended the deadline to provide and install these devices to on or before January 1, 2027.

The Department of Buildings (“Department”) is proposing to amend sections 908-02 and 3616-06 of Title 1 of the Rules of the City of New York to clarify installation and location requirements for natural gas detecting devices in residential buildings and to extend the deadline for allowing installation of a monitored battery primary power source for natural gas alarms in existing buildings.

On behalf of NEXELEC, a manufacturer of UL 1484-listed natural gas alarms, we welcome the Department’s proposed amendments to Sections 908-02 and 3616-06 regarding the installation and location of natural gas detection devices.

We appreciate the Department’s efforts to clarify installation requirements, introduce reasonable exemptions, and maintain the January 1, 2027 compliance deadline.

Based on our experience working directly with New York City property owners and managers, we would like to raise a few points for consideration:

1. Clarification of exemptions

The proposed exemption for dwelling units without gas appliances is a welcome improvement. However, determining whether gas piping or appliances are present immediately below a dwelling unit may prove challenging, particularly in older residential buildings.

We recommend providing practical guidance on how property owners should verify and document eligibility for these exemptions.

2. Consistent implementation across NYC properties

As the compliance deadline approaches, clear and accessible guidance will be essential to avoid inconsistent interpretations among property owners, installers, and enforcement personnel.

We would welcome practical examples illustrating the requirements for apartments with electric appliances, gas piping beneath dwelling units, and common areas containing gas-burning equipment.

Ultimately, our shared objective is to ensure that New York City residents are protected by reliable natural gas detection while making compliance straightforward, consistent, and achievable for building owners.

We appreciate the opportunity to provide feedback and would be pleased to contribute our technical and field experience to further discussions.

Best regards,

Sam Jones

Please clarify the central station monitoring and FDNY dispatch requirements for the following natural gas detection system configurations:

1. Line-operated, zoned system: Is a line-operated, zoned natural gas detection system required to transmit an alarm signal to a supervising central station? If so, must the central station dispatch the FDNY?

2. DC-powered control unit: If natural gas detectors are powered by a DC control unit, is the system required to transmit an alarm signal to a supervising central station? If so, must the central station dispatch the FDNY?

3. Wireless control unit: If natural gas detectors are powered by a wireless control unit, is the system required to transmit an alarm signal to a supervising central station? If so, must the central station dispatch the FDNY?

4. Shaft enclosing generator gas piping: Where natural gas detectors are required within a shaft enclosing gas piping that serves a generator, must activation of those detectors dispatch the FDNY?
