Local Law 152 Gas Piping Inspections in NYC.

Local Law 152 (LL152) was enacted in 2016 to improve gas line safety and reduce the risk of leaks and explosions in New York City buildings.  Local Law 152 requires all buildings in NYC, except those classified in occupancy group R-3, to undergo gas piping system inspections every four years. These inspections must be completed by a Licensed Master Plumber (LMP) or a qualified technician supervised by an LMP.
