Data provenance — public records only
- Palm Beach County — Florida DOR NAL assessment roll for Palm Beach County: owner names, mailing addresses, values, and recorded sales with price at month precision. The county's local business tax roll is not yet ingested, so no tenant layer yet.
Every fact on this page is drawn from the government records above — no listing sites, no scraped platforms, no third-party images. Facts from public records are uncopyrightable; each tenancy row carries its source and match confidence. Records can lag reality — a business-tax receipt or registration at an address is evidence of occupancy, not a lease confirmation.
