LL152

Local Law 152 requires periodic inspections of building gas-piping systems by qualified professionals, on a recurring cycle staggered by community district, with results filed and identified defects corrected on regulated timelines. Buildings without gas systems certify that fact instead. The law is a child of catastrophe — fatal gas explosions revealed that building gas systems could go unexamined for decades.

The filing trail reads like the other periodic regimes: current filings mark baseline compliance, gaps accrue penalties and signal inattention, and repeated defect findings on the same system mark aging infrastructure approaching replacement. For multifamily acquisitions, gas-system status is a capital-planning line item the record dates precisely.
