Local Law 152 Inspection & Certification Services in NYC

Licensed Master Plumbers. Complete Compliance. No Loose Ends.

New York City doesn’t treat gas safety lightly — and neither do we. Local Law 152 requires periodic inspections of gas piping systems in most buildings across the five boroughs. Inspection deadlines are based on your Community District and recur every four years, meaning compliance isn’t a one-time task, but an ongoing responsibility.

At Nationwide Plumbers, our team of Licensed Master Plumbers (LMPs) provides full-service LL152 compliance, from confirming whether your property qualifies to performing repairs and filing the required certifications. No guesswork. No missed deadlines. Just experienced professionals who know NYC code inside and out.

What Local Law 152 Covers

Local Law 152 was enacted to reduce the risk of gas leaks, fires, and explosions in New York City buildings. In a city where systems age, tenants change, and renovations happen constantly, periodic inspections are designed to catch issues before they turn into emergencies.

The law requires most buildings with gas piping to be inspected once every four years by a Licensed Master Plumber. That inspection isn’t just a “check the box” moment, the New York City Department of Buildings (DOB) expects a qualified evaluation of exposed gas piping, documented properly, then filed on time.

Most residential and commercial buildings with gas piping must comply. Exemptions are limited, including:

• One- and two-family homes
• Buildings classified as Occupancy Group R-3

If your property uses gas for heat, cooking, hot water, or commercial operations, LL152 is likely part of your ongoing compliance plan.

LL152 Inspection Deadlines by Community District (2026–2028)

Local Law 152 runs in repeating four-year cycles, and the city assigns deadlines by Community District. If you’re managing multiple properties — or just trying to plan ahead — knowing the schedule helps you avoid the year-end rush.

Here’s the current timeline we’re working under:

• Due by Dec 31, 2026: Community Districts 4, 6, 8, 9, 16
• Due by Dec 31, 2027: Community Districts 11, 12, 14, 15, 17
• Due by Dec 31, 2028: Community Districts 1, 3, 10 (Cycle 3 begins again)

Because the requirement repeats, the smartest approach is to treat LL152 as a routine compliance milestone: something you schedule early, document cleanly, and revisit on a reliable cadence.

How We Handle Your LL152 Inspection from Start to Finish

A lot of LL152 problems start before the inspection ever happens: wrong assumptions about occupancy, unclear records, and uncertainty about whether a building even qualifies. We take that off your plate.

Our process is built to be straightforward: we confirm what’s required, inspect thoroughly, explain what we find, and keep the filing side tight.

Here’s what you can expect when you work with our Licensed Master Plumbers:

• Qualification review. We help determine whether the law applies to your property and what DOB expects based on building type and gas system presence.
• On-site inspection. We inspect exposed gas piping from the point of entry through accessible common areas and tenant spaces, following DOB requirements.
• Clear reporting. You receive a formal Gas Piping System Periodic Inspection Report within the required timeframe.
• Repairs when needed. If deficiencies are found, we handle permits, corrective work, and follow-up documentation.
• DOB filing. We submit the required certification(s) through the DOB portal.

This is what “complete LL152 service” actually means: not just showing up with a flashlight, but carrying the job through to compliance.

What We Look for During the Gas Piping System Inspection

An LL152 inspection is focused on the condition and safety of exposed gas piping. That includes looking for signs of deterioration, unsafe connections, and installation issues that can create risk.

We’re inspecting with two goals in mind: safety first, and DOB-ready documentation second. We typically evaluate:

• Piping condition (corrosion, damage, deterioration, improper support)
• Joints and connections for signs of leakage or failure
• Evidence of unpermitted or non-code work
• Emergency shutoff accessibility and required safety signage
• Overall compliance with current NYC code requirements for gas piping systems

If your building has no gas piping, LL152 still isn’t something you ignore. You must file a certification stating that condition. We handle that documentation and submission so your building file is clean.

Repairs, Permits & Filing Support

When issues are found, there are next steps to follow. Beyond the inspection, the DOB is looking for timely corrective action and accurate filing. Missing a deadline or submitting incomplete paperwork can create penalties even when the inspection itself was performed.

With Nationwide Plumbers, you work with Licensed Master Plumbers, so you don’t have to coordinate multiple vendors to get from “problem found” to “problem solved.”

We handle the compliance-critical portion of the process, including repairs and documentation, with services such as:

• Permit filing and code-compliant corrective work
• Repair or replacement of damaged/corroded piping
• Removal of illegal or outdated connections
• Utility coordination if gas service restoration is required
• Final certification filing once conditions are corrected
