How the Local Law 152 schedule works

Local Law 152 of 2016 requires a gas piping inspection at least once every four years for most NYC buildings with gas. Your year depends only on your building's community district number, and the same numbers apply in every borough. So Manhattan CD 6 and Brooklyn CD 6 are on the same schedule. The inspection and the owner's certification are due by December 31 of your district's year.

Worked example

A 30-unit walk-up in Brooklyn Community District 6 is in sub-cycle C. Its cycle 2 inspection is due in 2026. Say a licensed master plumber inspects on October 20, 2026 and finds a corroded section of piping. The owner must file the inspection certification within 60 days, by December 19, 2026, and in any case by December 31. A certification that the condition was fixed is due 120 days after the inspection, by February 17, 2027 (or 180 days, by April 18, 2027, if the first certification said more time was needed). The next inspection is due in 2030.

If the owner files nothing by December 31, 2026, the building faces a $5,000 civil penalty. A three-family house would face $1,500. To clear the violation, the owner must pay and file the certification.

Step by step

  1. 1

    Confirm your district and exemption

    Look up your building in DOB’s LL152 property search (it lists each covered building and its deadline), or find the community district on the Department of City Planning’s website. One- and two-family (R-3) homes and certain DOF building classes are exempt.
  2. 2

    Book a licensed master plumber

    Since Local Law 142 of 2025 took effect on February 22, 2026, anyone inspecting under a master plumber must hold a DOB journeyman plumber registration and finish DOB-approved training. The inspector must notify DOB at least two days before the inspection.
  3. 3

    Get the report within 30 days

    The plumber must give you the inspection report within 30 days. Gas leaks or hazardous conditions are reported right away to you, the utility and DOB.
  4. 4

    File the certification within 60 days

    Since July 27, 2026, certifications are filed in DOB NOW: Safety with a $35 fee. A certification filed more than 60 days after the inspection does not count, and a new inspection is required.
  5. 5

    Certify corrections

    If conditions need repair, file the certification of correction within 120 days of the inspection, or 180 days if you noted that more time was needed.

Edge cases

  • One 180-day extension of the due date can be requested through DOB NOW (with a $35 fee). Only one extension is allowed.
  • DOB lists DOF classes M3 (2 or fewer permanent dwelling units) and M4 (20 or fewer occupants) as exempt only under those conditions.
  • New owners, bankruptcy and other situations can qualify for a penalty waiver under 1 RCNY §103-10.

Related deadlines

Gas inspections are one of several recurring filings. Check your facade cycle with the FISP / Local Law 11 checker, estimate carbon fines with the Local Law 97 fine estimator, and see everything due this year in the landlord compliance calendar. Tenants dealing with a gas shutoff should read no cooking gas in your NYC building.

Common questions

Which buildings are due for a Local Law 152 inspection in 2026?

Buildings in community districts 4, 6, 8, 9 and 16 in every borough (sub-cycle C). The inspection and certification are due by December 31, 2026. Districts 11, 12, 14, 15 and 17 are next, in 2027.

Do one- and two-family houses need a gas piping inspection?

No. Buildings in occupancy group R-3, which covers one- and two-family homes, are exempt. DOB also lists Department of Finance building classes that do not need to comply, including A0–A9, B1, B2, B3, B9, CM, N2, S0, S1, S2 and V, plus M3 and M4 buildings below set size limits. Three-family houses are not exempt.

What has to be filed after the inspection?

A licensed master plumber (or a qualified person working under one) inspects and gives the owner a report within 30 days. The owner must file the inspection certification with DOB within 60 days of the inspection. If conditions need correcting, a certification that they were fixed is due within 120 days, or 180 days if the first certification said more time was needed.

What is the penalty for missing the LL152 deadline?

Under 1 RCNY §103-10, an owner who fails to file the certification by the due date faces a civil penalty of $5,000, or $1,500 for a three-family building. Owners can request one 180-day extension before the due date.

Are there filing fees in 2026?

Yes. Since LL152 filings moved to DOB NOW: Safety on July 27, 2026, DOB charges $35 for an inspection certification, $35 for an extension request, $35 for a certification of correction, $375 for a one-time certification that a building has no gas piping, and $480 for documentation of no gas service.

Re-verified 2026-10-12: sub-cycle groups and cycle 2/3 years from 1 RCNY 103-10(a)(4) and the DOB schedule table; R-3 exemption and DOF class list (incl. M3/M4 limits) from DOB page; 30-day report, 60-day certification, 120/180-day correction, 2-day prior notice, 180-day extension, $5,000/$1,500 penalties and waiver grounds from 1 RCNY 103-10; Local Law 142 of 2025 (effective Feb 22, 2026) and $35/$375/$480 fees from Follow-up #7; DOB NOW: Safety move on July 27, 2026 from Follow-up #8; one extension only from Follow-up #6. New buildings: tenth year after a CO issued on or after Dec 6, 2016 (103-10(a)(5)). Fixed status logic so sub-cycle D shows 2027 (not 2031) and the previous deadline correctly. Worked example dates recomputed (Oct 20 + 60/120/180 days).
