NYC Local Law 152

What is NYC Local Law 152?

                    What is NYC Local Law 152?

According to the NYC Local Law 152, starting from January 1, 2020, gas piping systems in all buildings, except for buildings classified in occupancy group R-3, must be inspected by a Licensed Master Plumber (LMP), or a qualified individual working under the direct and continuing supervision of a LMP, at least once every four years according to the schedule set out in 1 RCNY §103-10.

Which buildings does the law apply to?

Building gas piping systems except for gas piping systems classified in occupancy group R-3 must be periodically inspected – there is no change here from the proposed rules. As Per the code, occupancy group R-3 includes “buildings or portions thereof containing no more than 2 dwelling units,” like convents and monasteries with fewer than 20 occupants, group homes, and 1 & 2 family dwellings. If you are unsure of your property classification, you can find your building’s occupancy group on the Certificate of Occupancy. You can also reach out to The Cotocon Group for more details.

When Does LL152 Go into Effect?

In a big change from the originally proposed rules, inspections are now being organized by Community District – not borough.

To make sure buildings have enough time to prepare, the first cycle start date were pushed from 2019 to 2020.

Inspections must be performed and submitted once every 4 years, with different due date cycles for four groups of Community Districts:

January 1, 2020 – December 31, 2020: Community Districts 1, 3, and 10 in all boroughs

January 1, 2021 – December 31, 2021: Community Districts 2, 5, 7, 13, and 18 in all boroughs

January 1, 2022 – December 31, 2022: Community Districts 4, 6, 8, 9, and 16 in all boroughs

January 1, 2023 – December 31, 2023: Community Districts 11, 12, 14, 15, and 17 in all boroughs

As the law says, each Community District listed applies to that number for all boroughs at the same time (CD 1 in Manhattan, in the Bronx, etc.). If you do not know which District your building is located in, reach out to our team.

What are the penalties for noncompliance?

A building owner who fails to submit a certification required to be submitted…on or before the filing due date specified…will be liable for a civil penalty of ten thousand dollars ($10,000).


Depending on the type of building, the requirements of LL152/2016 can be an inspection and certification, a certification only, or none. If you are unsure about the specific requirements for your building, or the assigned dates to submit the inspection report, you can get a professional opinion from The Cotocon Group.
