Free Gas Alarms Available to NYC Homeowners Before 2027 Deadline

National Grid and the New York City Department of Buildings are giving away natural gas detectors to small residential property owners. The free units are distributed at educational events held across the city. Supplies are limited and go to attendees on a first-come, first-served basis.

These distributions prepare owners for Local Law 102. The City Council passed the law in 2025. It requires owners of residential buildings with gas piping to install a natural gas alarm in every dwelling unit by January 1, 2027. The devices monitor air for methane. They sound an alarm before a leak reaches dangerous levels.

The law covers apartment buildings, one and two-family homes, hotels, motels, and single room occupancy buildings. Alarms must be placed near gas appliances. Owners may use hard-wired, plug-in, or battery-powered models. The devices must meet UL 1484 or UL 2075 safety standards.

At the events, staff demonstrate how the devices work. They also explain what the law requires. Phil Sandy, Chief Operating Officer of New York Gas, said, “Every New Yorker should feel safe at home, and National Grid is proud to partner with the New York City Department of Buildings to help residents prepare for the new natural gas alarm requirement.” He added that the alarms provide an early warning for families.

The city has identified specific battery-powered models that meet the requirements. These include the Aware Buildings NG-101, DeNova DD623NCV, DD620NV, and ML-310ES, Heiman HM-733NS, Nexelec VIGAS, and Universal Security Instruments USI/NG/10YR. Officials urge buyers to check for the UL listing before purchasing other models. Battery-powered units can be mounted in any location where detection works best without needing an outlet.

Natural gas powers heating, stoves, and appliances in the city. While safe when contained, leaks can occur due to poor maintenance or damaged pipes. A single spark can ignite the gas. Breathing leaked gas can also cause serious health problems for high-risk groups.

National Grid advises customers to act immediately if an alarm sounds or if gas is smelled. People should move to a safe location and call 911 or the gas emergency line at 718-643-4050.
