What Is Local Law 152?

Local Law 152 is a New York City law that requires periodic inspections of gas piping in certain buildings. The goal is to reduce the risk of gas leaks and improve public safety. Inspections must be conducted every four years, based on the community district of your building.

LL152 Requirements by Building Type

  1. One- and Two-Family Homes (R-3 Occupancy)
    These buildings are typically exempt from LL152 inspections unless they have a commercial space or other mixed-use elements. Double-check your certificate of occupancy if you’re unsure.
  2. Multi-Family Buildings (R-2 and R-1 Occupancy)
    Most apartment buildings fall into this category. If your building has gas piping, you will need to complete an LL152 inspection during the required cycle.
  3. Commercial and Mixed-Use Buildings
    Any building with commercial space and gas piping must comply with LL152. This includes restaurants, retail shops, and mixed-use developments.
  4. Buildings Without Gas
    Even if your building has no gas piping, you may still need to file a certification stating that fact. Failing to file this document could result in penalties. (See our next post on LL152 and buildings with no gas).
