A DOB violation for failing to file the Local Law 152 gas piping inspection certification (GPS2) by your building’s four-year community-district deadline.

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 inspection certification (the GPS2) is not filed by the applicable due date, DOB issues a Notice of Deficiency (NOD) and a violation goes on the building’s record.
Why You Got It
Common triggers: the owner missed the building’s four-year community-district deadline; no LMP was hired; the GPS2 was not submitted within 60 days of the inspection; or the building was wrongly assumed exempt.
Consequences & Penalties
A civil penalty of $5,000 applies for failing to file a Gas Piping System Periodic Inspection Certification by the applicable due date. (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.)

How to Clear It
- Confirm the building is covered (R-3 and certain DOF building classes are excluded).
- Find the building’s Community District to determine its applicable four-year cycle deadline.
- Hire a Licensed Master Plumber (verify the active license via DOB License Search) to inspect the exposed gas piping.
- The LMP delivers the GPS1 report to the owner within 30 days of the inspection.
- The owner submits the GPS2 certification (LMP-signed/sealed) via the online portal within 60 days of the inspection.
- If conditions need correction, file the corrected GPS2 within 120 days (or 180 days if additional time was flagged) after permitted corrective work.
Timeline
Deadlines run on four-year cycles by Community District. After inspection: GPS1 to owner within 30 days; GPS2 filed within 60 days; corrected GPS2 within 120 days (or 180 days if extended). A one-time 180-day extension of the due date may be requested via the online portal if the building cannot be inspected in time.
