Understanding NYC Local Law 152: Gas Piping Inspections

If you own a building in New York City, Local Law 152 affects you. Here is what the law requires, who has to comply, and how to stay ahead of the deadlines.
Local Law 152 of 2016 requires periodic inspections of the gas piping systems in most NYC buildings. The inspection must be performed by, or under the direct supervision of, a Licensed Master Plumber (LMP) — and the results filed with the Department of Buildings. The goal is simple: catch gas leaks and unsafe conditions before they become emergencies.
Which buildings need an inspection?
The requirement applies to most buildings except one- and two-family homes (occupancy group R-3). Inspections are due once every four years, on a schedule organized by Community District.
Who is due in 2026?
- Community Districts 4, 6, 8, 9 and 16 in all boroughs must be inspected during the 2026 calendar year.
- If you are not sure of your Community District, you can look it up on the NYC Planning website by address.
What does the inspection cover?
A licensed plumber inspects all exposed gas piping from the point of entry through public spaces, checks for leaks with appropriate equipment, looks for illegal connections and corrosion, and confirms that gas-detection and shut-off conditions are sound. After the inspection you receive a certification; any defects must be corrected and re-inspected.
What happens if you miss it?
Failing to file on time can result in civil penalties and a non-compliance filing against the property. Because the work must be done by a Licensed Master Plumber, the smartest move is to schedule early in your cycle year rather than waiting until December.
