What is Local Law 152


New York City council passed Local Law 152 in 2016 as a part of a gas safety package. Local Law 152 requires that New York City building owners have their gas piping inspected periodically. The law applies for all buildings except for buildings classified in occupancy group R-3.

Who can perform Local law 152 gas inspection

The local Law 152 gas inspections can only be performed by a licensed master plumber (LMP) or a technician with 5 years’ experience who is working under the direct supervision of a LMP and has completed an approved 7 hour training and passing of written/practical knowledge check exam. The Licensed master plumber must complete and provide the Gas Piping System Periodic Inspection Report, GPS1 which details all the results that the building owner or the Department of Buildings can review. The report should also include a list of conditions requiring corrections, frayed or worn out piping components that effects the reliable operation, non-compliance to the building code or any illegal connections, detection of any combustible gas. If no conditions were identified which required corrections, the Licensed master Plumber must also provide Gas Piping System Periodic Inspection Certification, GPS2 which must then be submitted to the Department of Buildings.

If the Licensed master plumber determines any hazardous conditions, it must be immediately notified to the building owner, gas utility company, National Grid or Con Edison and the Department of Building’s Plumbing Enforcement Inspections Unit. The building owner must then immediately get all the identified hazardous conditions corrected by hiring a licensed and insured plumbing company and filing all the required paperwork with the Department of buildings.

The building owner must submit the GPS1 report to Department of Buildings within 60 days of receipt of the report from the licensed master plumber. If the inspection report is submitted after 60 days of the inspection, a new inspection must be performed by a licensed master plumber. The building owner must preserve the reports and certifications for 10 years and must be made available to the department of buildings upon their request.


In the original law, the penalty for noncompliance was a fine of $10,000. But the rule was recently revised and effective 08/11/2021, the penalty will be reduced to $5,000.

Buildings exempt from Local Law 152
