Local Law 152 of 2016 requires the gas piping systems in most NYC buildings to be inspected at least once every four years. It applies to all buildings except one- and two-family homes and other buildings classified in occupancy group R-3, and the year a building is due depends on its community district.
The inspection must be done by a Licensed Master Plumber (LMP), or by a qualified journeyman plumber working under an LMP's direct and continuing supervision. It covers exposed gas piping in common spaces, including hallways, rooftops and non-residential tenant spaces. The owner then has to file a certification with DOB on time and certify that any conditions found were corrected.
BC360 tracks the Local Law 152 inspection cycle for each building, coordinates the plumber, and keeps the filings on schedule.
Inspection years follow the four-year schedule in 1 RCNY §103-10, and each deadline is December 31 of the due year:
Filing rules that apply in every cycle:

We confirm that LL152 applies, find the building's community district and due year, and check for open Notices of Deficiency.
A Licensed Master Plumber inspects the exposed gas piping, after notifying DOB at least two days ahead.
We track the inspection report and the certification filed in DOB NOW: Safety within 60 days of the inspection.
If conditions are found, we coordinate the repairs and permits and track the correction certification.
Our Local Law 152 inspection management may include:
A missed Local Law 152 deadline means a civil penalty of up to $5,000 per building, and a certification filed more than 60 days after the inspection does not count, so the inspection has to be done again.
If the plumber finds an unsafe or hazardous condition, the plumber must immediately notify the owner, the gas utility and DOB, and the owner must act right away to correct it. Planning the local law 152 inspection early in the due year leaves time to correct what is found before the 120-day and 180-day deadlines run.
BC360 tracks Local Law 152 next to the building's other periodic inspections, such as boilers, elevators and façades, so each due date sits on one compliance calendar.
BC360 is not a plumbing contractor. The inspection, the certifications and any gas work are handled by Licensed Master Plumbers. BC360 coordinates them, tracks the deadlines and keeps the paperwork together.
