LL152 no gas piping certification: when the filing is one-time
This page only works when the building truly has no gas piping. If piping still exists anywhere, stop and move to the no-active-gas-service page instead.
What this page covers
Use this page when
Use this page only when the building truly has no gas piping. This is a one-time certification path under the current DOB guidance, not a recurring-cycle no-service path.
This answer stops working the moment gas piping still exists anywhere in the building, even if service is not active.
No gas piping anywhere in the building system
One-time certification path under the current DOB guidance
Signer can be a utility company, registered design professional, or licensed master plumber
What this page covers
What to collect before filing
Keep the building identity and signer details ready before you treat the answer as settled.
The point is to prove no piping, not just no active service.
BIN or BBL and exact building identity
Statement of the no-gas-piping condition
Signer identity and utility or license details
Any building notes that rule out a dormant-service scenario
What this page covers
Use a different page when
Many wrong filings happen because a utility shutoff is mistaken for a no-piping condition.
If piping still exists, even as abandoned or inactive piping, this page is no longer the right fit.
Gas piping still exists even if service is off
Abandoned or hidden piping has not been ruled out
Utility shutoff is being confused with piping removal
Required sequence
What to prepare next
Confirm there is no gas piping anywhere in the building before using this one-time certification path.
Collect BIN or BBL plus the signer details for the utility company, registered design professional, or LMP who will certify the condition.
Keep this page separate from no-active-gas-service cases, which stay recurring and cycle-sensitive.
Decision boundary
Escalate before you continue when
You are relying on a utility shutoff alone, but piping may still exist in the building.
Abandoned, hidden, or hard-to-confirm piping has not been ruled out.
The building may still belong on the no-active-gas-service path instead of the one-time no-piping certification path.
LL152 applies to all buildings except one- and two-family homes and other buildings in Occupancy Group R-3.
DOB lists exempt DOF classes including A0-A9, B1-B3, B9, CM, M3 with 2 or fewer permanent dwelling units, M4 with 20 or fewer occupants, N2, S0-S2, and V.
Cycle 2 sub-cycle C covers community districts 4, 6, 8, 9, and 16 from January 1, 2026 through December 31, 2026.
If the building has no gas piping, a certification must be submitted and no further LL152 action is necessary unless gas piping is later installed.
GPS1 is due from the LMP to the owner within 30 days of inspection and GPS2 is due from the owner to DOB within 60 days.
If the building has gas piping but no active gas service and no appliances connected, the owner must submit utility and owner statements through the DOB portal.
The utility statement for buildings without active gas service must include the last date gas was supplied and the date the building was fully deactivated from utility service.
Documentation for no active gas service is required every cycle rather than once.
Certification that a building has no gas piping is now a one-time submission and may come from a utility company.
Inspection entities must notify DOB at least two days before the inspection and use the cancellation workflow if the inspection is canceled.
Resolving a failure-to-file violation requires payment of the civil penalty and submission of certification or qualifying no-gas documentation.
A civil-penalty waiver request is available by email with supporting documents.
The amended fee schedule includes $35 filing fees for inspection certification, extension requests, and correction certifications, plus $375 for no-gas-piping certification and $480 for no-gas-service documentation.
The 2026 amendment adds fees, clarifies one-time no-gas-piping certification, requires no-active-gas-service documentation every cycle, and adds the two-day inspection notification.
The rule states that a certification is not considered filed while it remains in pre-filing or quality-assurance-failed status.
The rule allows one 180-day extension for the inspection and related filing.
The rule text sets the civil penalty at $1,500 for a 3-family building and $5,000 for all other buildings.
Penalty-waiver categories include new owner, government ownership, bankruptcy, state of emergency, building conversion or misclassification, demolition, sealed or vacated building, no gas piping work in progress, no active gas service, and gas work in progress.
Decision basis
Why this page matters
Use this page when the building truly has no gas piping and you need to know who can certify it, what to collect, and why the filing is different from no active gas service.

Best used whenThe next filing step is still not obvious.
Use this page when gas piping still exists but the building no longer has active gas service and you need the recurring documentation path, not the no-gas-piping page.
Use the LL152 checker to see whether the building likely needs inspection, which cycle applies, and which filing path matches the gas status.
