What does NYC Local Law 152 require for gas piping inspections, and when is yours due?
Local Law 152 of 2016 requires a Licensed Master Plumber to inspect the gas piping in every New York City building except one- and two-family homes and other R-3 buildings at least once every four years. Your year depends on your community district. After the inspection, you file a certification with the Department of Buildings within 60 days, and a missed filing can bring a $5,000 civil penalty.
When your building is due
The Department of Buildings sets the year by the community district your building is in. Look up your district on the Department of City Planning's site, then find your row.
| Sub-cycle | Community districts | Cycle 2 | Cycle 3 |
|---|---|---|---|
| A | 1, 3, 10 | 2024 | 2028 |
| B | 2, 5, 7, 13, 18 | 2025 | 2029 |
| C | 4, 6, 8, 9, 16 | 2026 | 2030 |
| D | 11, 12, 14, 15, 17 | 2027 | 2031 |
Each cycle runs from January 1 to December 31 of that year. DOB also publishes a property-by-property list and an address search under its LL152 compliance tool, so you can confirm your building and deadline directly.
Is your building covered?
The law applies to every building except one- and two-family homes and other buildings in occupancy group R-3. DOB lists Department of Finance building classes that are exempt, including the A and B classes for one- and two-family homes. Any apartment building of three or more units is covered.
- No gas piping at all: a Licensed Master Plumber or a New York State licensed engineer or architect files a certification saying so, and you are done.
- Gas piping, but no gas service and no connected appliances: file a signed statement from the utility with the dates service ended, and your own signed certification. Before gas service resumes, you need a permit, inspections and the certification.

The inspection and the filing deadlines
- Hire a Licensed Master Plumber (LMP), or a qualified person working for one. Check the license is active with DOB's License Search and look at the disciplinary records in Know Your Construction Professional.
- The LMP inspects the gas piping system.
- Within 30 days, the LMP gives you a Gas Piping System Periodic Inspection Report. If the LMP finds an unsafe or hazardous condition, the LMP must immediately notify you, the gas utility and DOB, and you must act right away to correct it, with any required permits.
- Within 60 days of the inspection, you submit the Gas Piping System Periodic Inspection Certification, signed and sealed by the LMP, through DOB's online portal.
- If conditions needed correcting, submit a certification that they were corrected within 120 days of the inspection, or within 180 days if your earlier certification said more time was needed.
If you cannot get the inspection done in your year, DOB allows a one-time 180-day extension of the due date through its online portal. The inspection still has to happen before the extension ends.
Example a made-up 18 unit building in Brooklyn Community District 12 is in sub-cycle D, so its second-cycle inspection is due in 2027. The LMP inspects on March 10, 2027 and finds a corroded section in the cellar that needs replacing. The report is due by April 9 (30 days), the certification by May 9 (60 days) and the correction certification by July 8 (120 days), or September 6 (180 days) if the first certification said more time was needed. Missing the certification deadline risks a $5,000 civil penalty.
Working inside occupied apartments
The inspection covers the piping system, which often means getting into units with gas ranges. Give tenants the entry notice your lease and New York law require, schedule by line so the plumber works floor by floor, and have a plan for units where the tenant cannot be home. If a hazardous condition means the utility shuts off gas, tenants lose cooking gas until the repair passes, so line up the repair crew before the inspection, not after.
How DoorKeeping keeps the dates straight
In DoorKeeping, open a work order for the inspection and send it to your plumber by link. Keep the LMP's report and both certifications in the property's documents, and the plumber's invoices are read and coded into that building's books. DoorKeeping can email tenants about access days. Ask Claude or ChatGPT when the last inspection was and what was corrected, and you have it for the next cycle in four years.
