Building details
Does this building need LL152 inspection?
Start with the smallest set of building facts you already know, then narrow the answer until the next LL152 filing step is clear.
Public checker
Start here to find the likely LL152 branch, due timing, and next filing step.
Use only the building facts you know. This checker separates no gas piping from no active gas service before it points you to the next move.
What changes the answer
Use only the fields that change coverage, due-cycle timing, or the no-gas versus no-active-service branch.
Official references checked: 2026-04-14. 6 city sources behind this checker.
Why certainty changes
Coverage, district, and gas status drive the primary branch. Missing any of the three should lower certainty before it lowers trust.
- Confirm building identity before escalation.
- Separate gas piping from active gas service.
- Open the next guide only after the verdict stabilizes.
Records brief after the public check
Need a sendable records brief?
After the checker settles the likely path, open the records brief and send the branch, reply path, and today ask in one page.
- Run the public checker first and let the branch stabilize.
- Use the records brief when the building operator needs the path, reply route, and today ask in one message.
- Keep the filing guide and the records brief separate.
Starter scenarios
Use a starter only when you want to preload a repeated records-brief scenario after the public checker. Replace the building reference with the real address, BIN, or BBL before you send the brief.
Use a starter when you want to pressure-test the records brief after the branch logic is already understood.
