Read a job, permit, and certificate chronology
Follow dated construction records while keeping every relationship linked, partial, ambiguous, or not established.
What can a sequence of job, permit, and certificate records establish?
Chronology is a typed relationship view over admitted DOB records, not a project-status prediction.
How PropSignal reads it
- Create dated event nodes from source-reported job, permit, and certificate records.
- Join records only through exact admitted job, permit, certificate, BIN, or BBL evidence.
- Assign each proposed edge a linked, partial, ambiguous, or not-established state.
- Display missing later evidence as an unresolved chain—not proof that work stopped or occupancy is unlawful.

What this does not establish
- That permitted work was completed, approved, or performed as filed.
- Legal occupancy, code compliance, project delay, or construction quality.
Dates and missing evidence
- Date meaning
- Each event keeps its source-reported date and retrieval time. A later retrieved record is not treated as a later real-world event unless its effective date supports that order.
- When evidence is missing
- No later permit or certificate found in the checked sources means exactly that; it does not prove no record exists elsewhere or no work occurred.
