Known limitations
Missing fields and caveats
These notes travel with the source. A live sync cannot promote itself to healthy if its required field contract breaks.
Known missing or inconsistent fields
- Declared valuation is an estimated job cost supplied with the filing.
- Electrical, elevator, and LAA permits require separate datasets.
Public interpretation caveats
- PermitProspect ingests a rolling subset of the available records, not their full history.
- Exact coordinates and owner names are not republished.
- An approved permit is not proof that work has started or that a contractor is seeking vendors.
