Local Law 152 runs on a four-year cycle, and it’s easy to lose track of exactly where a building falls in it. Community Districts 4, 6, 8, 9, and 16 are the group on the clock this year, with every gas piping inspection in those districts due by December 31. That deadline can feel far off in the middle of summer, right up until it isn’t.
Which Buildings Are on This Year’s Clock
The current group covers a wide swath of the city. In Manhattan, that includes Chelsea and Hell’s Kitchen, Murray Hill and Gramercy, the Upper East Side, and Morningside Heights. The same cycle reaches neighborhoods in Brooklyn, Queens, and the Bronx as well, since every community district in the city gets grouped into one of four sub-cycles rather than the deadline running borough by borough.
Not every building is on the hook. One- and two-family homes are exempt from Local Law 152 entirely, and in Manhattan specifically, the requirement applies to properties housing more than two families. Anything larger — apartment buildings, mixed-use properties, commercial spaces with gas service — falls under the inspection requirement if it sits in one of this year’s five districts.
What the Inspection Covers
A Local Law 152 inspection is a visual and instrument-based check of a building’s exposed gas piping — the sections that are open to view, not piping run behind walls, above drop ceilings, or underground. A Licensed Master Plumber walks the property with a combustible gas detector, checking piping at the point of entry, gas meters, hallways and corridors, mechanical and boiler rooms, and any exterior or rooftop piping.
Only a Licensed Master Plumber, or someone working under one’s direct supervision, is qualified to perform the inspection and sign off on the results.
What’s New This Cycle
A few rules changed for 2026 that didn’t apply during the last inspection cycle. Commercial tenant spaces — stores, restaurants, and other leased units with gas lines — are now explicitly part of the inspection scope, not just building-wide common areas and exposed piping in hallways and mechanical rooms. Filing also moved fully online through the DOB NOW: Safety portal, and paper submissions are no longer accepted.
The filing process itself now comes with fees attached, including a charge for submitting the inspection certification and separate fees for buildings that need to certify they have no gas piping or no active gas service. These fees are modest individually, but they add up on top of the cost of the inspection itself, and they’re easy to overlook when budgeting for compliance.
The Case for Scheduling Now, Not in the Fall
Every building in a given sub-cycle has the same December 31 deadline, which means every building owner in Community Districts 4, 6, 8, 9, and 16 is working against the same calendar. Licensed Master Plumbers who perform these inspections get booked up fast in the final months of the year, when thousands of buildings across the affected districts are all trying to schedule at once.
Getting an inspection done in the summer or early fall avoids that bottleneck entirely, and it also builds in time to handle anything the inspection turns up. If a defect gets identified — corrosion, an improper connection, anything that doesn’t meet code — it has to be corrected and re-certified within 120 days of the inspection, or 180 with an extension. Scheduling early keeps that repair window from colliding with the December deadline itself.
What Happens If the Deadline Gets Missed
Missing the December 31 deadline for a building’s district can result in a civil penalty from the Department of Buildings, and enforcement has gotten more consistent in recent cycles rather than less. A full breakdown of the fine structure is available for building owners who want the specifics, but the short version is that it’s a real cost, and one that’s entirely avoidable by scheduling the inspection before the deadline rather than after.
