Local Law 152 (LL152): Everything NYC Building Owners Need to Know in 2025

 As New York City continues to prioritize safety and infrastructure integrity, Local Law 152  remains one of the most important regulations building owners must understand and comply with. Enacted to enhance gas line safety across the five boroughs, LL152 is not just a regulatory requirement—it's a critical safeguard for tenants, property investments, and the community at large.

At iag Energy, our mission is to help property owners navigate LL152 with ease and efficiency. In this post, we’ll break down everything you need to know about Local Law 152, what it means for your property, and how iag Energy can support you through every step of the compliance process.

What Is Local Law 152 (LL152)?

LL152, part of the NYC Gas Piping Inspection Laws passed in 2016, mandates periodic inspections of gas piping systems in most buildings throughout the city. The inspections must be carried out by a Licensed Master Plumber (LMP) or a qualified individual under their supervision.

The purpose of LL152 is to detect leaks, corrosion, illegal connections, and other potential gas-related hazards before they result in dangerous incidents. The law applies to all buildings except for one- and two-family homes classified under occupancy group R-3.

LL152 Inspection Timeline – What You Need to Know

To manage the high volume of inspections, the NYC Department of Buildings (DOB) developed a rotating schedule based on a building's community district. This cycle repeats every four years.

Buildings must file a certification within the calendar year their district is due. Missing your deadline can lead to substantial fines and violations.

What Happens During an LL152 Inspection?

During a Local Law 152 inspection, a qualified plumber will evaluate the visible gas piping from the point of entry into the building through public corridors and boiler/mechanical rooms. The interior of apartments is not inspected unless requested by the owner.

Inspectors look for:

Gas leaks

Corrosion or deterioration

Illegal connections

Improper installations

Code violations

Following the inspection, you'll receive:

GPS1 Report: A detailed inspection report

GPS2 Certification: Filed with the DOB within 60 days if the system passes

If unsafe conditions are found, they must be addressed immediately. A follow-up inspection may be required, along with an updated filing to confirm resolution.

LL152 Compliance for Buildings Without Gas

Even if your building does not have a gas piping system, LL152 still applies. In this case, a registered design professional (such as an architect or engineer) or a licensed plumber must submit a certification stating that no gas piping exists.

This step must be completed on the same four-year cycle as buildings with gas systems.

What Are the Penalties for Non-Compliance?

Failure to comply with Local Law 152 can result in serious consequences:

$5,000 civil penalty for missing the filing deadline

Additional DOB violations

Insurance complications

Safety risks for occupants

Avoiding these issues is easy when you work with an experienced partner like iag Energy. We stay ahead of deadlines and ensure all your documentation is handled professionally and on time.
