New York City’s Local Law 152 of 2016 mandates periodic inspections of gas piping systems in most buildings to improve safety and prevent hazardous gas leaks. This regulation was enacted as part of a broader safety package following a series of gas-related explosions in the city. Owners, engineers, and property managers in NYC must understand this law to stay compliant and avoid steep penalties.
Overview of Applicable NYC Regulations
Local Law 152 requires that buildings with gas piping systems (except one- and two-family homes classified under Occupancy Group R-3) undergo gas inspections every four years. The law assigns inspection years based on the building’s Community District, with staggered deadlines to manage volume.
Key elements of Local Law 152 include:
- Visual Inspection of Gas Piping
A Licensed Master Plumber (LMP) or someone working under their direct supervision must visually inspect all exposed gas piping from the entry point to common and mechanical areas. This ensures the system is intact, secure, and not visibly compromised by corrosion or improper installation. - Leak Detection Using Approved Instruments
Gas leak detection must be performed using a portable combustible gas detector in public corridors, mechanical rooms, boiler rooms, and other accessible non-residential spaces. This identifies any hazardous gas leaks that may not be visible but pose serious risk. - Gas Piping System Periodic Inspection Report (GPS1)
The inspector must provide this report to the building owner within 30 days of the inspection. It outlines the results, including any conditions requiring correction. - Gas Piping System Periodic Inspection Certification (GPS2)
The owner must file this form with the NYC Department of Buildings (DOB) within 60 days of the inspection. This certifies that the inspection was completed and details any corrective actions taken, if necessary. - Civil Penalties for Noncompliance
Buildings that fail to comply may be fined $10,000 per instance. Failure to submit GPS2 on time or skipping the inspection altogether both count as violations.
Common Challenges Faced by Property Stakeholders
Many NYC property stakeholders face practical barriers to meeting Local Law 152 compliance. These include:
- Scheduling Inspections on Time
Many owners delay until the last minute, only to find that Licensed Master Plumbers are fully booked. Since the inspection must be completed and submitted within the assigned calendar year, early planning is essential. - Gaining Access to Required Spaces
Mechanical and boiler rooms, as well as common corridors, must be accessible for the inspection. In mixed-use or residential buildings, this can require coordination with multiple tenants or staff members. - Determining Applicability and Timelines
Some owners aren’t sure if Local Law 152 applies to their building or don’t know their Community District. Misidentifying this can result in missed deadlines and fines. - Proper Documentation and Filing
Submitting both the GPS1 and GPS2 accurately and on time is crucial. Incorrect information or late filings can still trigger violations, even if the inspection itself was done.
Best Practices for Achieving and Maintaining Compliance
To make Local Law 152 compliance seamless, here are proven best practices:
- Start Early by Identifying Your Community District
Find your building’s Community District on NYC Planning’s portal. Match it to the inspection schedule released by the DOB to determine when your building’s gas piping inspection is due. - Hire a Licensed Master Plumber with Relevant Experience
Only inspections performed by (or under) an LMP are accepted. Choose professionals who understand Local Law 152 requirements, not just general gas line safety. - Keep a Dedicated Compliance Folder
Maintain an organized file for every inspection cycle that includes: the GPS1 report, GPS2 certification, plumber license verification, correction documentation (if applicable), and receipts. DOB may require proof up to 10 years later. - Act Swiftly on Repair Timelines
If unsafe or non-hazardous conditions are found, you typically have 120 or 180 days to fix them. After corrections, you must submit an updated GPS2 to avoid penalties.

Realistic Case Scenarios
Scenario 1: Deferred Compliance Rescued in Time
A 12-unit multifamily building in Brooklyn missed its scheduled inspection year and was flagged by DOB during a routine audit. The owner contacted VetraCheck after receiving a violation warning. Our team quickly identified a Licensed Master Plumber, completed the inspection, filed an expedited GPS2, and coordinated necessary corrections. The violation was dismissed and penalties were avoided.
Scenario 2: Non-Gas Building Needs Proof
A retail property in Manhattan had no active gas piping system but was still required to submit a certification confirming its gas-free status. VetraCheck coordinated a visual walkthrough and prepared the required certification of “no gas piping,” which was accepted by DOB and avoided fines.
Frequently Asked Questions
Q: Which buildings are exempt from Local Law 152 inspections?
A: One- and two-family homes and buildings classified under Occupancy Group R-3 are exempt. You can confirm your occupancy group by checking your Certificate of Occupancy on the DOB website.
Q: What happens if an inspection reveals a gas leak?
A: If an immediately hazardous condition (like a leak) is found, the inspector must notify the owner, utility company, and DOB right away. Gas service may be shut off until repairs are completed and certified.
Q: Can I request an extension if I can’t meet the deadline?
A: Yes. DOB allows a one-time, 180-day extension request. You must apply through their online portal before your filing deadline, and approval is not guaranteed.
Q: Are tenant spaces part of the inspection?
A: No. Inspectors are not required to enter tenant units. Inspections focus on exposed gas piping in common areas, utility spaces, and other non-tenant-accessible locations.
