Typical ranges
For a small walk-up with one meter room, an LL152 inspection and filing is typically a few hundred dollars. Mid-size elevator buildings usually run from the high hundreds into the low thousands, and large co-ops and rental complexes with many risers cost several thousand dollars or more.
These are ranges, not quotes. Two buildings with the same unit count can be priced very differently, depending on how the gas piping is laid out.
What drives the price
- Number of gas meters, service entrances and risers
- Size and number of meter rooms, cellars and boiler rooms
- Access: locked rooms, tenant spaces that hold exposed piping, required escorts
- Commercial tenants with their own gas lines, such as restaurants
- Whether the plumber files the GPS1 and GPS2 in DOB NOW as part of the price
Corrections are quoted separately
If the inspection finds conditions that need correcting, such as corroded piping, illegal connections, missing supports or unpermitted work, the repairs are priced on their own. Minor items can be a few hundred dollars. If DOB or the utility shuts off gas, repiping a riser can run into the tens of thousands.
Ask for the inspection price and an hourly or unit rate for typical corrections in the same quote, so you are not negotiating under pressure after the report.
Compared with not filing
DOB lists a $5,000 civil penalty for failing to file the inspection certification by the due date. For almost every building, inspecting is cheaper than the penalty, before counting the safety risk.
