Data provenance — public records only
- Miami-Dade County Property Appraiser — assessment roll — Parcel identity, site address, recorded owner, use code, areas, year built and assessed values, via the county's public GIS services (MD_LandInformation, PaGis layer).
- Miami-Dade County Local Business Tax roll — Business-tax receipts: business name, premises address (incl. suite/floor), account status and start date, via the county's public GIS services.

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.
