Local Law 152 was created in 2016 following a series of gas pipe explosions in Manhattan. To ensure this never happens again, buildings are required to undergo periodic inspections of gas piping systems and inspections must be carried out by a Licensed Master Plumber (or a qualified individual working under one). This law applies to all buildings except for gas piping systems of occupancy group R-3. The inspections are now organized by Community District as opposed to the borough and must be performed once every four years, as per the chart below.
Within 30 days of the inspection, the Licensed Master Plumber must use the Gas Piping System Periodic Inspection Report Form (GPS1) to submit a report containing the results of the inspection. Within 60 days, the Licensed Master Plumber must submit a Gas Piping System Periodic Inspection Certification (GPS2) to the department. Effective December 31st, owners of buildings located in Community Districts 1, 3, and 10 in all boroughs must submit this signed and sealed GPS2. This does not apply to one- and two-family homes. If the GPS2 indicates that a correction is needed, the Licensed Master Plumber must complete an Inspection Certification stating that the conditions have been corrected. This must be submitted by the owner within 120 days of the inspection.
Additionally, if the building does not contain a gas piping system, a signed and sealed GPS2 must still be completed and submitted by a Licensed Master Plumber stating that the building does not contain gas piping. This is also to be submitted once every four years and follows the dates listed in the table above.
All forms relating to Local Law 152 are to be submitted via the online portal at www.nyc.gov/DOBgaspipecert.
