Property owners in New York City who deal with gas piping sometimes assume that a recent ConEd or National Grid inspection satisfies their Local Law 152 obligation. It doesn’t. The two inspections exist under different legal frameworks, are conducted by different parties, serve different purposes, and neither one substitutes for the other. Knowing the distinction matters because failing to complete both when both are required produces compliance problems that are entirely avoidable.
What Local Law 152 Inspections Are
Local Law 152 is a New York City ordinance that requires periodic inspections of gas piping systems for most properties with three or more units. The law mandates an inspection once every four years, scheduled by community district, with a December 31 deadline for whichever districts are due in a given year.
The inspection must be conducted by a Licensed Master Plumber — a credential specific to New York City. The LMP examines exposed gas piping between the gas meter and tenant spaces, checks connections and materials, and tests for leaks. The results go into a Gas Piping System Periodic Inspection Report, and a signed certification must be filed with the NYC Department of Buildings within 60 days of the inspection. Any deficiencies identified must be repaired within 120 or 180 days depending on severity.
The 2026 LL 152 inspection schedule covers Community Districts 4, 6, 8, 9, and 16 in all five boroughs, with a deadline of December 31, 2026.
What Utility Inspections Are
Utility inspections are conducted by Consolidated Edison or National Grid — not by a licensed master plumber, and not under the authority of the NYC Department of Buildings. They are mandated by the Public Service Commission and carried out according to PSC specifications that vary by location, building type, and utility provider.
Like LL 152 inspections, utility inspections are generally limited to visible gas piping. In some cases they can be more in-depth than an LL 152 inspection depending on the specific requirements for a given property and utility territory. Their scope, frequency, and requirements are determined by the PSC and the utility’s own protocols — not by the city ordinance that governs LL 152.
A ConEd or National Grid inspector who visits a property, examines the gas system, and finds everything in order has fulfilled a utility requirement. That visit generates no GPS1 report, involves no DOB filing, and satisfies nothing under Local Law 152.
Why One Does Not Replace the Other
The two inspections exist under entirely separate legal authority and satisfy entirely separate obligations. LL 152 is a municipal law enforced by the NYC Department of Buildings. Utility inspections are required by the Public Service Commission and enforced by the utility companies. Meeting one requirement does not create compliance with the other under any circumstance.
A property owner who received a utility inspection last month is no more LL 152-compliant than one who has never had a utility inspection. A property owner who completed their LL 152 inspection last year but hasn’t had a utility inspection is still subject to whatever utility inspection requirements apply to their property.
The practical implication is straightforward: both requirements need to be tracked and met independently. If your community district is due for an LL 152 inspection this year, completing your utility inspection on the same day as the LL 152 inspection does not satisfy both — it just means both happened to occur on the same day. The certifications, the filing requirements, and the parties involved are different.
What Happens When Either Is Missed
Missing the LL 152 deadline without having filed for an extension exposes a property owner to civil penalties that can reach up to $10,000. The LL 152 violations and repair process involves not just the fine but the requirement to complete the inspection and file the proper documentation before the violation can be resolved.
Utility inspection requirements and the consequences of non-compliance vary depending on the utility provider and the specific PSC requirements for the property. ConEd and National Grid each have their own protocols for properties that miss required inspections or fail to address identified issues.
