Local Law 102 of 2025: Natural-gas detector deadline amendments
Amends the timing framework for required natural-gas detectors in NYC buildings.
New York City jurisdiction · Sources checked September 15, 2026. Law numbers repeat by year. These educational summaries are not legal advice or a complete compliance checklist. Later amendments, agency rules, building characteristics, and effective dates determine the requirements for a particular property. Use the linked City sources to confirm current obligations.
Why it matters
This is a deadline amendment, not proof that every property is exempt from detector requirements. Confirm the current installation date, covered occupancies, device standards, and any DOB extension before relying on an older notice or purchasing equipment. Gas alarms and periodic piping inspections address different risks.
In practice
A project example
An owner revises a detector procurement schedule after checking current agency guidance, while keeping gas-piping inspections on a separate compliance calendar.
