NYC Local Law 152 requires periodic inspections of gas piping systems by a Licensed Master Plumber. Protect your building, your tenants, and stay compliant with expert inspections and GPS filing.
LL152 deadlines are based on your Community District
LL152 was enacted after tragic gas explosions in NYC. It requires periodic inspection of all gas piping systems in buildings.
Building owners must have exposed gas piping inspected by a Licensed Master Plumber (LMP) or a qualified individual working under their supervision.
LL152 applies to all buildings in NYC that have gas service, with limited exceptions for small residential properties.
LL152 inspections are required every 4 years, with deadlines staggered by community district.
