Local Law 152 periodic inspection
Every building with gas piping, except one- and two-family homes, needs its exposed gas piping inspected by a Licensed Master Plumber every four years, with the certification filed with DOB. Manhattan community districts 4, 6, 8 and 9 are due December 31, 2026.
Other times to inspect
- Before buying a building or a townhouse
- Before a kitchen or boiler-room renovation that touches gas lines
- After a utility or DOB gas shutoff, before service is restored
- When a new commercial tenant, such as a restaurant, adds gas equipment
- One- and two-family homes: not required by LL152, but worth doing on old piping
If you smell gas
Do not use switches, phones or flames near the smell. Leave the building and call 911 or Con Edison's gas emergency line from outside. An inspection is for planned work, not for an active leak.
