Local Law 152 NYC: Complete Gas Inspection Guide for Building Owners (2026)
Local Law 152 is one of the most important gas safety regulations affecting property owners in New York City. If you own a multi-family building, mixed-use property, or commercial property with gas piping, compliance is not optional — and penalties can be severe.
This guide breaks down everything NYC landlords, co-op boards, and property owners need to know about Local Law 152, including inspection requirements, deadlines, penalties, and how to stay compliant.
What Is Local Law 152?
Local Law 152 was passed by the New York City Council in 2016 as part of a broader gas safety initiative aimed at preventing gas leaks, explosions, and hazardous building conditions.
The law requires periodic inspections of gas piping systems in most NYC buildings to ensure they are safe and properly maintained.
Although Local Law 152 officially went into effect on January 1, 2019, inspections began in 2020 after the NYC Department of Buildings (DOB) finalized the rules and procedures.
