Blog Article
If you own or manage a property in New York City, you’ve probably heard of LL152 NYC the law that mandates routine inspections of gas piping systems across all five boroughs. Enacted to prevent gas-related accidents and improve public safety, LL152 New York is more than just another compliance box to check—it’s a vital part of protecting tenants, buildings, and the city’s infrastructure.
At iag Energy, we specialize in helping building owners navigate the complexities of LL152 New York quickly, affordably, and stress-free. In this comprehensive guide, we’ll break down what LL152 means, who it applies to, how to stay compliant, and why iag Energy is your trusted partner for the job.
What Is LL152 NYC?
Local Law 152 (LL152 NYC) is part of a package of gas safety regulations passed in 2016 by the New York City Council. The law requires that periodic inspections of gas piping systems in most buildings be conducted by a Licensed Master Plumber (LMP) every four years.
This law was introduced in response to several gas explosions and leaks that occurred in residential buildings throughout the city. It is designed to identify and fix dangerous gas piping issues before they can lead to costly damages or life-threatening emergencies.
Who Must Comply with LL152 New York?
LL152 New York applies to most buildings in NYC except for:
One- and two-family homes that are classified as occupancy group R-3
Buildings without any gas piping (though these must still file a “no gas” certification)
If you own or manage a multifamily, mixed-use, or commercial building with a gas connection, LL152 NYC applies to you.
Inspection Deadlines Under LL152 NYC
To manage the volume of inspections, the NYC Department of Buildings (DOB) created a rotating compliance schedule based on Community Districts. Every building must be inspected once every four years according to this schedule:
| Due Year | Community Districts |
| 2024 | 1, 3, 10 |
| 2025 | 2, 5, 7, 13, 18 |
| 2026 | 4, 6, 8, 9, 16 |
| 2027 | 11, 12, 14, 15, 17 |

What Happens During an LL152 New York Inspection?
Here’s what iag Energy’s team of licensed professionals does during a typical LL152 NYC inspection:
Step 1: Visual Assessment
A Licensed Master Plumber inspects exposed gas piping from the point of entry through public spaces like basements, mechanical rooms, and corridors.
Step 2: Leak Detection
Using approved methods, we check for active gas leaks or corrosion that could pose a threat.
Step 3: Issue Reporting
The inspector completes a GPS1 Report outlining their findings and delivers it to the building owner within 30 days.
Step 4: Certification Filing
You must submit a GPS2 Certification to the Department of Buildings within 60 days of the inspection date. If repairs are needed, you have up to 120 days (or more with an extension) to correct the issue and file an updated certification.
What If My Building Has No Gas?
Even if your building has no gas piping, you’re still required to comply with LL152 NYC by submitting a certification signed by a Licensed Master Plumber or Registered Design Professional confirming the absence of a gas system.
Missing this step can still result in violations, so it's essential not to overlook it.
LL152 NYC Non-Compliance Penalties
Failing to comply with LL152 NYC can result in:
$5,000 fines for late or missing certifications
DOB violations that can delay property sales, insurance renewals, or refinancing
Increased liability if an accident occurs without inspection records
