Natural gas systems are essential to the infrastructure of New York City for cooking, heating, and other utilities. The city implemented Local Law 152 as part of a larger gas safety initiative to improve safety and lower the risk of gas leaks and explosions. Property owners are clearly required by this law to perform routine gas piping inspections and provide the NYC Department of Buildings (DOB) with the necessary paperwork.
Whether you own a small residential building or a large mixed-use property, understanding the Local Law 152 NYC gas inspection law is crucial to staying compliant, avoiding fines, and protecting your tenants.
What Is Local Law 152 in NYC?

Local Law 152 of 2016 is part of the New York City gas safety package. It specifically requires that all buildings equipped with gas piping systems must undergo gas line inspections every four years. These inspections must be carried out by a Licensed Master Plumber (LMP) who is registered with the DOB.
Even if your building doesn’t have any gas piping, you’re still required to submit a certification to the DOB confirming that. Failure to file the GPS‑2 certification by the deadline now carries a flat $5,000 civil penalty per violation, may result from noncompliance with the inspection or failure to submit the required reports.
By detecting possible problems such as leaks, corrosion, and unauthorized alterations in a building’s gas piping system, this gas inspection law seeks to avert dangerous circumstances and mishaps.
Who Is Required to Comply With Local Law 152?

The Local Law 152 compliance requirements apply to:
- All buildings with gas piping systems classified under occupancy groups R-3 or larger.
- Mixed-use buildings, multi-family dwellings, and certain commercial properties.
- Owners of buildings without gas piping must still submit a No Gas Piping Certificate.
The NYC DOB has established a rotating schedule based on community districts, meaning that not all buildings are inspected at once. Property owners must check their assigned schedule and complete inspections by the Local Law 152 deadline for their district.
What Happens During a Local Law 152 Gas Inspection?

During a Local Law 152 gas piping inspection for buildings, the licensed plumber follows a strict protocol defined by the DOB. This includes:
- Visual inspection of all exposed gas piping from point-of-entry to individual apartments and mechanical rooms.
- Checking for corrosion, rust, or visible leaks in piping, joints, and valves.
- Verifying that shutoff valves and regulators are accessible and operational.
- Ensuring that piping systems have not been tampered with or illegally modified.
- Checking clearances between gas lines and combustible materials.
After the inspection, the plumber submits two important documents:
- GPS1 – Gas Piping System Periodic Inspection Report (within 30 days of inspection).
- GPS2 – Gas Piping System Certification (within 60 days, if no repairs are needed; or within 120 days if corrections are made).
If repairs require more time, the Licensed Master Plumber can request, on the GPS‑1 report, up to 180 days total from the inspection date to complete and file the corrected GPS‑2.
These documents must be submitted directly to the DOB to prove compliance.
What Are the Local Law 152 Inspection Costs in NYC?

The cost of a Local Law 152 gas inspection varies depending on the property’s size, the complexity of its gas piping, and the number of units that need to be inspected. On average, pricing ranges from a few hundred dollars for small buildings to over $1,000 for larger buildings with multiple units.
However, these inspections are significantly more affordable than the fines – or potential hazards – that can result from non-compliance or gas-related incidents. A seamless, open process free of unexpected costs is guaranteed when working with a respectable plumbing business.
