LL152 unsafe or hazardous condition: what happens immediately after inspection
An unsafe or hazardous LL152 result is not a normal follow-up page. Use this route when the inspection result may trigger immediate notice to the utility, DOB, and the owner before the regular filing sequence continues.
What this page covers
Use this page when
Use this page when the inspection result points to an unsafe or hazardous condition and the next move is no longer just GPS1, GPS2, or a routine correction deadline.
The goal here is to separate immediate reporting obligations from the later paperwork so the case does not get treated like an ordinary compliance follow-up.
Unsafe-condition cases can trigger immediate notice requirements
Treat utility, DOB, and owner notice as distinct from later filing steps
Keep the inspection result and any emergency action details together
What this page covers
What not to blur together
This page is not general emergency advice and it is not the same as every correction case.
The practical distinction is whether the condition requires immediate notification first, or whether the building is already back in a normal corrected-certification or GPS2 path.
Do not downgrade a hazardous finding into a normal timing question
Do not assume later filing deadlines replace immediate reporting duties
Do not lose the original inspection language when asking for help
Required sequence
What to prepare next
Preserve the original inspection language before you turn this into a normal filing discussion.
Separate immediate notice steps from later certification or correction steps.
Keep the owner, utility, and DOB notification facts together before asking for route help.
Decision boundary
Escalate before you continue when
The inspection result may require immediate utility, DOB, or owner notice before routine filing work continues.
You are not sure whether the condition belongs in an emergency-response path or a standard correction path.
The case summary already dropped the original unsafe or hazardous inspection language.
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.
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.
Decision basis
Why this page matters
Use this page when the inspection did not end as a routine filing case because the condition may be unsafe, hazardous, or serious enough that the next move is immediate reporting rather than ordinary scheduling.

Best used whenThe next filing step is still not obvious.
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.
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.
