NYC Local Law 152 Gas Piping Inspection Deadlines (2026–2031)

02

Check Your Building's Deadline

Enter the address below and we'll look up its community district and show the year it's due. You can also find the district on the Department of City Planning's community district profiles, which is where DOB sends owners.

03

What Has to Happen, and by When

The inspection is only the first step. These are the filing windows from 1 RCNY §103-10, counted from the inspection date unless noted.

1. 1

   Notify DOB 2 Days Ahead

   Since 2026, the inspector must notify DOB at least two days before the inspection.

2. 2

   Inspection by December 31 of Your Year

   A licensed master plumber, or a qualified inspector working for one, inspects exposed gas piping from the point of entry through the public spaces, hallways, corridors, and boiler and mechanical rooms.

3. 3

   GPS1 Report to the Owner Within 30 Days

   The plumber gives the owner the inspection report and certification, listing any leaks, non-code-compliant or illegal connections, and worn parts.

4. 4

   GPS2 Certification to DOB Within 60 Days

   The owner files the GPS2 with DOB within 60 days of the inspection. A GPS2 filed after that requires a new inspection.

5. 5

   Corrections Certified Within 120 Days

   If the report lists conditions to fix, the plumber certifies the corrections within 120 days of the inspection, or within 180 days if the GPS2 says more time is needed.

04

What Changed in 2026

Amendments to the LL152 rule took effect January 3, 2026, and Local Law 142 of 2025 took effect February 22, 2026. The changes that matter to owners:

• Two-day notice: the inspector must notify DOB at least two days before each inspection.
• Stricter inspector qualifications: someone inspecting under a master plumber now needs a Journeyman Plumber registration plus DOB-accepted training of at least seven hours.
• Defined scope and equipment: the law spells out what the inspection covers and the leak detection instruments required.
• Buildings without gas service now need a utility statement every cycle, not just once.
• Buildings with no gas piping at all certify that only once, and the certification can now come from the utility.
• Violations: to resolve one, the owner has to pay the penalty and file the certification.
• Filing moves to DOB NOW: Safety, with new fees once it does.

05

Penalties for Missing the Deadline

Failing to file an inspection certification carries a civil penalty of $5,000, or $1,500 for a three-family building (1 RCNY §103-10(f)). Some articles online quote $10,000; we couldn't find that number in the rule or on DOB's site.

The penalty doesn't replace the inspection. The building still needs it done and filed, and since 2026 the violation stays open until both the penalty is paid and the certification is filed. The rule allows penalty waivers in limited cases.

06

Which Buildings Are Exempt

Buildings in occupancy group R-3 (one- and two-family homes) are exempt. DOB also lists these Department of Finance building classes as exempt:

• A0–A9 (one-family homes) and V (vacant land)
• B1, B2, B3, and B9 (two-family homes)
• CM, N2, S0, S1, and S2
• M3 with two or fewer dwelling units, and M4 with 20 or fewer occupants

Three-family homes, apartment buildings, mixed-use, and commercial buildings are covered. A building with no gas service still has to file the utility statement each cycle.

07

What Happens if the Inspector Finds a Problem

Most findings are conditions to correct and certify within the 120-day window. In our inspections the common ones are capped "future use" connections, missing or broken meter bars, corrosion, missing pipe supports, unlabeled piping, and old unpermitted work.

Inspecting early in your year leaves time to fix findings before December 31 without rushing, and lets the repair and the correction filing go to the same licensed plumber. See our Local Law 152 inspection service.
