Local Law 152 Gas Inspection: NYC Requirements and 2026 Deadlines
Last updated: March 2026
Local Law 152 requires gas piping inspections every 4 years by a Licensed Master Plumber. Community Districts 4, 6, 8, 9, and 16 are due by December 31, 2026. Inspections cost $300 to $1,000+ for most buildings. As of February 2026, all GPS2 filings must go through DOB NOW with a new $35 fee.
If your building has gas service in New York City, Local Law 152 probably applies to you. This law requires periodic inspections of your gas piping system to catch leaks and hazardous conditions before they cause explosions or fires. The city takes this seriously, and the penalties for non-compliance keep getting steeper.
This guide covers everything you need to know about Local Law 152 in 2026, including the major changes that took effect in February, the inspection process, costs, and deadlines by community district.
What Is Local Law 152?
Local Law 152 of 2016 requires periodic inspections of gas piping systems in NYC buildings. The law was passed after several deadly gas explosions in the city, including the 2014 East Harlem explosion that killed 8 people and the 2015 East Village explosion that killed 2.
The law applies to all buildings with gas service, with two exceptions: owner-occupied 1-2 family homes and small buildings that have no gas piping. If you own a multi-family building, commercial property, or mixed-use building with gas, you're covered.
Inspections must be performed by a Licensed Master Plumber (LMP) and happen on a 4-year cycle based on your building's community district. After the inspection, the building owner files a GPS2 certification with the Department of Buildings.
2026 Changes: What's New
Effective February 22, 2026, Local Law 152 got its biggest update since it was enacted. These changes affect how you file, what you pay, and how the DOB enforces compliance.
All-Digital Filing Through DOB NOW
GPS2 certifications must now be filed electronically through DOB NOW. The old process of mailing paper forms is gone. This means building owners or their representatives need a DOB NOW account to submit the certification.
New $35 Filing Fee
For the first time, the DOB charges a fee for GPS2 submissions. The $35 fee applies to every filing. This is on top of whatever the LMP charges for the inspection itself. It's a small amount compared to the inspection cost, but it's a change owners need to know about.
Stricter Enforcement
The DOB has ramped up oversight of Local Law 152 compliance. Buildings that miss their inspection deadline are being flagged more aggressively, and ECB violations for non-compliance carry escalating fines with each missed cycle.

Local Law 152 inspections follow a rotating schedule based on community district. You cannot complete your inspection early. You must wait until your district's designated year.
| Deadline Year | Community Districts |
|---|---|
| 2026 (Jan 1 - Dec 31) | Districts 4, 6, 8, 9, 16 |
| 2027 (Jan 1 - Dec 31) | Districts 11, 12, 14, 15, 17 |
The schedule repeats every 4 years using the same district groupings. If your district was last due in 2022, you're due again in 2026.

The Inspection Process: Step by Step
Here's exactly what happens during a Local Law 152 gas inspection, from start to filing.
- Determine your community district. Confirm your building's district and check whether your inspection year has arrived. You can verify this through the NYC Department of City Planning website.
- Hire a Licensed Master Plumber (LMP). Only an LMP can perform the inspection. Get quotes from several plumbers, as prices vary significantly. Make sure they're familiar with LL152 requirements and GPS2 filing.
- Schedule the inspection. The LMP needs access to all exposed gas piping from the building's point of entry through individual units. You may need to coordinate tenant access. Give tenants advance notice.
- The LMP inspects all exposed gas piping. They check for leaks, corrosion, improper connections, and other hazardous conditions. If they find a hazard, they must act immediately. There is no option to "come back later." If gas needs to be shut off, it gets shut off.
- Submit the GPS2 certification. Within 60 days of the inspection, the building owner must file the GPS2 form through DOB NOW. The form must be signed and sealed by the LMP who performed the inspection. The new $35 filing fee applies.
- Address any conditions found. If the inspection revealed issues that weren't immediately hazardous, you'll need to complete repairs and potentially schedule a follow-up inspection.
The entire process, from hiring the plumber to filing the GPS2, typically takes 2 to 4 weeks for a straightforward inspection. Buildings with conditions that need repair will take longer.
How Much Does a LL152 Inspection Cost?
Costs depend on building size, complexity, and how many units need access. Here's what to budget:
| Building Type | Inspection Cost |
|---|---|
| Small building (10 units or less) | $400 - $699 |
| Mid-size building (11-50 units) | $700 - $2,000 |
| Large/complex building (50+ units) | $2,000 - $10,000+ |
| DOB filing fee (GPS2) | $35 |
| Gas leak repairs (if found) | $1,140+ per repair |
The biggest cost variable is repairs. If the LMP finds a gas leak or hazardous condition, they're required to address it immediately. A simple valve replacement might cost a few hundred dollars. Replacing corroded piping through multiple floors can run into the thousands.
There are no "pre-inspections" allowed under Local Law 152. Once the LMP starts the inspection, it's official. If they find a problem, they must act on it. You can't get a preliminary look first and then decide whether to proceed.
What the Plumber Inspects
The LMP inspects all exposed gas piping from the point of entry (where gas enters the building) through individual units. This includes:
- Gas meters and regulators
- Exposed piping in basements, boiler rooms, and mechanical spaces
- Risers running through the building
- Connections to gas appliances (stoves, boilers, water heaters)
- Any exposed piping in common areas and individual apartments
The inspector checks for gas leaks (using electronic detection equipment), corrosion, improper connections, non-code-compliant installations, and any conditions that could lead to a gas-related incident.
"Exposed" is the key word here. The law doesn't require opening walls or ceilings to inspect concealed piping. But if the LMP can see it, they must inspect it.
What Happens If the Inspector Finds a Problem
If the LMP finds a hazardous condition, they are legally required to take immediate action. This can include:
- Shutting off gas to the affected area or the entire building
- Notifying Con Edison if the condition is severe
- Making immediate repairs if feasible
- Tagging the condition for follow-up repair within a specified timeframe
Non-hazardous conditions (minor code issues, worn fittings that aren't yet leaking) get noted on the GPS2 report. The building owner is responsible for addressing these within a reasonable timeframe.
If gas service gets shut off, Con Edison will need to restore it after repairs are verified. This can add days or weeks to the process, depending on the scope of repairs and Con Edison's scheduling.
Penalties for Non-Compliance
The consequences of skipping your Local Law 152 inspection go beyond a simple fine.
- ECB violations for failure to inspect, with fines that escalate each cycle you miss
- Gas service shutoff if the DOB determines your building poses a hazard
- Property liens from unpaid violation fines (after 75 days, at 9% annual interest)
- Blocked permits on the property until violations are resolved
The DOB's enforcement has gotten stricter with the 2026 amendments. Buildings in districts that were due in 2022 and never complied are now being actively pursued. If you're behind on compliance, address it before the DOB comes to you.

Talk to Us Today →Tips for Building Owners
- Book your LMP early. Plumbers get booked up as the December deadline approaches. Buildings in 2026 districts should schedule inspections by Q2 or Q3 at the latest.
- Coordinate tenant access in advance. Send written notice to all tenants well ahead of the inspection date. The LMP needs access to every unit with exposed gas piping.
- Set up your DOB NOW account now. If you don't already have one, create an account at DOB NOW before inspection day so you're ready to file the GPS2 within the 60-day window.
- Budget for repairs. Don't assume your piping is fine. Older NYC buildings frequently have corrosion, improper connections, and other conditions that need remediation. Set aside $1,000 to $3,000 as a repair contingency.
- Keep your GPS2 filing confirmation. After filing through DOB NOW, save the confirmation receipt. You'll need it if the DOB ever questions your compliance status.
