County coverage

Where FactLot holds whole-county commercial property data, and how far it has been checked. Grey means not usable yet: not reviewed, not loaded, waiting on publisher terms, a sample only, or too old.

What the colors mean

  • Hosted lookups. Served by the hosted API at api.factlot.com on every plan, including the free tier. Call registry_coverage to list what is hosted. DC's data is also published as an open sample database (CC BY 4.0) you can run with the FactLot MCP server.
  • Audited, not yet hosted. The whole county's commercial roll is loaded from a source whose terms we recorded and verified, and an audit re-read the publisher's archived file and found the registry holds exactly its in-scope parcels, with no violations.
  • Loaded, not yet audited. The whole county is loaded from a verified source, with a per-county count and a data date in the review record, but the audit has not covered it yet.
  • Not usable yet. Everything else, including statewide loads with no per-county count, partial or sample loads, sources whose terms are still open, and data more than 400 days old.

Hosted lookups are open now for the counties marked hosted: Maryland, the District of Columbia, and Juab and Summit counties in Utah. To ask for another county, email us.

  • The freshness limit is 400 days before November 6, 2026, the latest source review date.
  • Machine-readable file: /coverage/counties.json. Full per-source terms and records: registry coverage.
  • Boundaries: US Census Bureau cartographic boundary files (public domain), via us-atlas.
