Look up the permit. Read the salvage clues.

Search one Chicago demolition permit number or street address. Get the public scope, issued date, contact cue, and an explainable reuse score without learning the City dataset’s query language.

Bounded public-record search

One permit or one address.

The lookup accepts only a permit identifier or a Chicago street address. It never forwards arbitrary database syntax.

Examples: permit 101084286 · 911 W Diversey Pkwy

Result for 101084286

No matching demolition record

Live City result
No wrecking or qualifying demolition record matched that exact lookup. Check the number or street format, then verify against the official City dataset.

The City record is the source of truth. Salvage Signal’s score is a heuristic layered on the public text and never proves availability, permission, condition, or a viable recovery window.

Why this lookup exists

A public record becomes useful when its limits stay visible.

01 / Find

Permit or address, not query language

The tool translates a narrow human lookup into a bounded request against the official dataset.

02 / Read

See the scope before guessing

Building type, masonry, stories, fixtures, detached structures, cost, and emergency timing can change which record deserves attention.

03 / Verify

Contact an authorized party

Ask who controls material recovery and whether that window remains open. Never infer access or ownership from the permit.

04 / Monitor

Turn repeated searches into a watch

The paid Daily Drop saves one material and area filter and sends ranked matches on business days.

Direct answers

Chicago demolition lookup questions.

01

How do I look up a Chicago demolition permit?

Enter a City of Chicago permit number or a street address. Salvage Signal sends a tightly bounded read-only query to the official Building Permits dataset and returns matching demolition records.

02

Does the lookup include every Chicago building permit?

No. This tool is intentionally limited to wrecking, demolition, and qualifying interior-demolition records. Use the official City dataset for unrelated permit types and full municipal history.

03

What does the salvage score prove?

The score only prioritizes public text clues such as masonry, timber, building scale, use, fixtures, reported scope, and emergency timing. It does not prove inventory, condition, ownership, permission, safety, or profit.

04

Can an agent call the demolition-permit lookup?

Yes. The public read-only endpoint is GET /api/permit-lookup?q=. It accepts one permit number or one Chicago street address and does not accept arbitrary database queries.
