LL152 corrected certification: what gets filed after conditions were fixed
A corrected certification is not the same step as GPS2. Use this page when the building already moved past the inspection result and now needs the follow-up correction filing path.
What this page covers
Use this page when
Use this page when the inspection already happened, conditions were identified, and the main blocker is what has to be filed after the correction work is complete.
The practical question is usually whether the building is still waiting on work, ready for corrected certification, or already late because the post-inspection clock kept running.
Start with the original inspection date and condition status
Keep the LMP report and the correction scope together
Separate corrected certification from GPS2 before deciding what is due
What this page covers
What usually changes the answer
Correction cases go wrong when owners treat every post-inspection filing as the same step.
The deadline, signer, and next move can change depending on whether the condition is already fixed, still being fixed, or needs a new inspection before certification.
Do not assume GPS2 closes the correction path
Do not assume a contractor invoice by itself is the final filing support
Do not wait on penalty notices to figure out whether corrected certification is already due
Required sequence
What to prepare next
Start with the original inspection date because the correction path runs from that sequence, not from the day you reopen the file.
Keep the inspection result, the correction scope, and the follow-up filing owner together before deciding what is now due.
Separate corrected certification from GPS2 so you do not treat every post-inspection step as the same filing.
Decision boundary
Escalate before you continue when
You still do not know whether the work is finished, whether a reinspection is needed, or whether corrected certification can already be filed.
The case may already be late because the post-inspection clock kept running while the work stayed unresolved.
You cannot yet tie the completed work back to the original condition language in the inspection output.
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.
Leak surveys terminate at tenant spaces, but inspectors still take readings at entries to those spaces.
Unsafe and hazardous conditions such as gas leaks, illegal connections, and non-code-compliant installations require immediate notification to the utility, DOB, and the owner.
GPS1 is delivered within 30 days of inspection and GPS2 is submitted by the owner within 60 days through the DOB portal.
If a different plumber certifies corrections, that plumber must conduct another inspection.
Owners who cannot complete an inspection by the cycle deadline may request one 180-day extension per cycle.
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 inspection found conditions, the correction work is already done or underway, and the open question is what the corrected-certification filing actually requires next.

Best used whenThe next filing step is still not obvious.
Use this case page when the inspection already happened and the open issue is GPS2, correction timing, or how to document follow-up work before deadlines stack.
Use this page when the building already looks covered and the open question is what gets filed next, who acts next, and which document starts the sequence.
