Local Law 152 Gas Piping Inspection Violation in NYC

What It Means

Local Law 152 of 2016 (rule 1 RCNY §103-10) requires that gas piping systems in all buildings — except one- and two-family homes and other Occupancy Group R-3 buildings — be inspected by a Licensed Master Plumber, or a qualified individual working for an LMP, at least once every four years. When the required inspection certification is not filed by the applicable due date, DOB issues a Notice of Deficiency (NOD) and a violation goes on the building’s record. GPS2 was the certification form name used under the legacy filing process: DOB’s Local Law 152 Follow-up #8 says LL152 certifications and related transactions moved to DOB NOW: Safety on July 27, 2026, and that the paper GPS2 is no longer required for new Cycle 2, Sub-cycle C submissions after the cutover.

Why You Got It

Common triggers: the owner missed the building’s four-year community-district deadline; no LMP was hired; the certification was not submitted within 60 days of the inspection; or the building was wrongly assumed exempt.

Consequences & Penalties

DOB currently says failure to file a Gas Piping System Periodic Inspection Certification by the applicable due date may result in a civil penalty of $5,000. (Some secondary sources claim escalated penalties for repeat cycles; that figure is not confirmed against a primary DOB source and is therefore not stated here — confirm against your notice.)

Information current as of 2026-06-21. Penalty amounts and deadlines change — confirm specifics against your violation notice or with a Licensed Master Plumber.

How to Clear It

1. 1Confirm the building is covered (R-3 and certain DOF building classes are excluded).
2. 2Find the building’s Community District to determine its applicable four-year cycle deadline.
3. 3Hire a Licensed Master Plumber (verify the active license via DOB License Search) to inspect the exposed gas piping.
4. 4The LMP delivers the GPS1 inspection report to the owner within 30 days of the inspection.
5. 5The owner submits the LMP-signed and sealed certification in DOB NOW: Safety within 60 days of the inspection.
6. 6If conditions need correction, submit the correction certification within 120 days (or 180 days when the initial certification states that additional time is needed) after permitted corrective work.

Timeline

Deadlines run on four-year cycles by Community District. After inspection: the GPS1 report goes to the owner within 30 days; the certification is submitted within 60 days; a correction certification follows within 120 days (or 180 days when the initial certification states that additional time is needed). A one-time 180-day extension of the due date may be requested in DOB NOW: Safety if the building cannot be inspected in time. DOB NOW filings do not appear in BIS, so a complete record review may require both systems.
