Local Law 152 has been part of life for NYC building owners since inspections began in 2020. Most property owners have been through at least one cycle by now and have a reasonable handle on what the law requires — schedule an inspection with a Licensed Master Plumber, get the certification filed, repeat every four years.
What many building owners don’t yet know is that there are now two updates to the law took effect in early 2026 that changed how inspections are conducted, who can conduct them, what they’re required to cover, and how they have to be filed. These aren’t minor procedural tweaks. For some building types — particularly mixed-use and commercial properties — the changes meaningfully expand the scope and cost of compliance.
This post breaks down exactly what changed, why it matters, and what you need to do about it if your inspection is coming up.
The Two Updates — What They Are and When They Took Effect
The changes come from two separate sources that arrived close together.
- Local Law 142 of 2025 was passed by the NYC City Council on September 25, 2025. It became law on October 25, 2025, and took effect on February 22, 2026. This is the bigger of the two changes — a comprehensive amendment that expanded the scope of what inspections must cover, tightened the qualifications required to conduct them, and made several other adjustments to how gas work is categorized under city code.
- The amendments to 1 RCNY §103-10 and 1 RCNY §101-03 are DOB rule changes — not new legislation, but formal updates to the Department of Buildings’ own rules governing how inspections are administered. These were proposed in September 2025, adopted by the DOB in November 2025, and took effect on January 3, 2026. They addressed the shift to digital filing, new fees, and penalty enforcement going forward into Cycle 2.
Together, these two updates represent the most significant changes to Local Law 152 since the inspection program began.
Change #1 — Commercial Tenant Spaces Are Now Explicitly Included
This is the change with the biggest practical impact for mixed-use buildings, commercial properties, and any building with retail or restaurant tenants.
Under the original interpretation of LL152, inspections covered exposed gas piping in public areas — hallways, common spaces, basements, boiler rooms, and building-wide systems up to the point where piping enters individual tenant spaces. Residential apartments were excluded from the interior inspection, and commercial tenant spaces occupied a gray area that different inspectors handled differently.
Local Law 142 of 2025 resolved that ambiguity definitively. As of February 22, 2026, non-residential commercial tenant spaces — restaurants, retail stores, daycares, businesses open to the public, and other commercial occupancies — are now explicitly included in the scope of the inspection. If your building has a restaurant on the ground floor or a retail tenant using gas-powered equipment, the inspector now needs access to that space as part of a complete inspection.
The reasoning behind this is logical. Commercial tenants, particularly food service operations, are among the highest-risk gas users in any building. Stoves, fryers, ovens, and other commercial cooking equipment represent significant gas load and potential hazard points. Including those spaces in the mandatory inspection is a genuine safety improvement — it’s also one that requires more time, more coordination with tenants, and more complexity to schedule.
Residential apartments remain excluded from the interior inspection. Individual dwelling units are still not part of the scope, and inspectors do not need to enter them. The change is specific to non-residential commercial tenant spaces.
For building owners with commercial tenants, the practical implication is that you will need to coordinate access to those spaces before the inspection. An inspector who cannot access a commercial tenant space cannot complete a full inspection. Plan ahead and give your tenants enough notice to make access available.
Change #2 — The Inspection Must Now Extend to the Point of Appliance Connection
This is a subtler change but worth understanding clearly. Local Law 142 also clarified that the inspection scope runs from the point where gas piping enters the building all the way through to the point of connection to each appliance.
Under the prior rules, there was some ambiguity about exactly where an inspector’s obligation ended. The new law makes it explicit — the visual survey and leak testing must cover the full length of exposed gas piping, including the connection point at each appliance in covered areas. This is a more thorough inspection than some building owners may have experienced in their first cycle, and it reflects the law’s intent to identify hazards at every point in the system rather than stopping partway through.
Change #3 — Stricter Inspector Qualifications
Before Local Law 142, the law required that inspections be conducted by a Licensed Master Plumber or someone working under the direct and continuing supervision of one. That basic requirement hasn’t changed. What has changed is what “working under an LMP” now means in terms of credentials.
Any technician performing an LL152 inspection on behalf of a Licensed Master Plumber — meaning anyone who is not themselves the LMP — must now meet both of the following requirements:
- Registered Journeyman — The technician must be a DOB-registered journeyman plumber. This requirement was already technically in effect as of July 1, 2025, but Local Law 142 formalized and expanded it.
- 7-Hour DOB Training — The technician must have completed a specific 7-hour Periodic Gas Inspector training course provided by a DOB-approved course provider. This training must be verified and uploaded to the DOB’s Digital Worker Wallet application — a credential system that makes it possible to confirm qualification on the spot during an inspection.
Licensed Master Plumbers themselves are not required to complete the 7-hour training. Their qualification is already embedded in their LMP license. But any technician working under them must have both the journeyman registration and the Worker Wallet credential.
What does this mean for building owners? If a technician shows up who is not the actual LMP, you have the right to ask them to display their credentials on the DOB Digital Worker Wallet application. If they can’t, they are not qualified to conduct your inspection under the current law. Working with a reputable, established plumbing firm like Empire Plumbing means this is handled automatically — but it’s worth knowing your right to verify.
Change #4 — All Filings Must Now Go Through DOB NOW
The amendments to 1 RCNY §103-10 and 1 RCNY §101-03, effective January 3, 2026, moved the entire LL152 filing process to the DOB NOW: Safety digital platform. Paper submissions are no longer accepted. All certifications, extension requests, and related documentation must be submitted digitally through the portal.
For most building owners, this is handled entirely by the Licensed Master Plumber who conducts the inspection — they file the Gas Piping System Periodic Inspection Certification (GPS2) on your behalf through DOB NOW after the inspection is complete. What matters from an owner’s perspective is confirming that your plumber is filing through DOB NOW and not relying on any older paper-based process.
Change #5 — New Filing Fees
The DOB rule amendments introduced filing fees for LL152-related submissions that did not previously exist. The current fees are:
- $35 to submit a Gas Piping Inspection Certification (GPS2)
- $35 to file an extension request (for the 180-day extension)
- $375 for a one-time “Certification of No Gas” filing for buildings that have no gas piping and want to be exempt from future inspection cycles
These amounts are modest relative to the cost of the inspection itself, but they represent a change from the prior system where filing was free. Make sure your plumber accounts for these fees in the process.
Change #6 — Two-Business-Day Advance Notification to the DOB
The DOB rule amendments also introduced a new procedural requirement: the Licensed Master Plumber must notify the Department of Buildings at least two business days before conducting an LL152 inspection.
This requirement generated significant pushback during the public comment period from plumbing contractors who noted that it reduces scheduling flexibility and makes last-minute inspections more complicated. The DOB’s response, in adopting the rule, was that the notification requirement does not prevent inspections from occurring on evenings, weekends, or holidays, and does not limit the number of inspections an inspector can schedule in a day. It simply requires advance logging of the intent to inspect in the DOB system.
For building owners, the practical implication is more lead time needed to schedule. If you’re trying to book an LL152 inspection with a short turnaround, there’s now a minimum two-business-day window built into the process before the inspection can legally occur.
Change #7 — Stricter Penalty Enforcement Beginning Cycle 2
The DOB rule amendments also formalized penalty enforcement for Cycle 2 — the current cycle running from 2024 through 2027. The DOB had been somewhat more lenient during Cycle 1, particularly given the unusual circumstances of COVID and the early rollout of the program. That leniency is no longer in effect.
Civil penalties for failure to file a Gas Piping Inspection Certification are currently $5,000 for most buildings and $1,500 for three-family dwellings. The DOB is actively issuing Notices of Deficiency and Notices of Violation for missed filings, and has made clear that Cycle 2 compliance will be enforced on the timeline as written.
If you already received a Notice of Deficiency from the DOB for a missed Cycle 1 filing, that notice remains open until you submit a valid Cycle 2 certification. It does not automatically close when Cycle 2 comes around — you need to actually complete the inspection and file to clear it. If you have questions about a violation or deficiency notice, Empire Plumbing can help.
Who Needs to Be Paying Attention Right Now
If your building is in Community Districts 4, 6, 8, 9, or 16 in any borough, your deadline for the current inspection cycle is December 31, 2026. These are the same districts that were due in 2022 during Cycle 1, but the compliance landscape looks significantly different this time around.
The new requirements — commercial tenant access, expanded inspection scope, stricter inspector credentials, advance notification, digital filing — all add time and complexity to what was already a process that tended to back up at the end of the year. Booking your inspection early in 2026 is genuinely the right move. The year-end rush for Licensed Master Plumbers during inspection deadline years is real, and with the new advance notification requirement adding two business days to every booking, the window is even tighter than it used to be.
If your district’s deadline was December 31, 2025 — Community Districts 2, 5, 7, 13, or 18 — and you haven’t yet completed your inspection, you are currently in violation. You can request a 180-day extension through DOB NOW, but the clock is already running. Contact a Licensed Master Plumber immediately. For more on what to do if you’ve missed your deadline or have an existing LL152 violation, Empire Plumbing has a full guide on that as well.
For properties in districts coming up in 2027 — Community Districts 11, 12, 14, 15, and 17 — you cannot complete your inspection early, but you can get on the schedule now and familiarize yourself with the new requirements before your deadline arrives.
What to Do Next
If your building is due this year, the steps are straightforward. Work with a Licensed Master Plumber experienced in LL152 inspections. Make sure all areas of your building — including commercial tenant spaces — are accessible on the day of the inspection. Confirm your plumber is filing through DOB NOW and using appropriately credentialed technicians. Allow enough lead time for the two-business-day pre-notification requirement.
