Miami-Dade County (pop. 2.7 million) uses a folio number as its parcel identifier -- a 13-digit code, not an APN; the county abbreviates its Property Appraiser office as PA or MDPA. The parcel layer is at gisweb.miamidade.gov (MD_LandInformation MapServer, layer 26) and exposes 44 confirmed fields. Owner-name search uses UPPER() LIKE on TRUE_OWNER1; the fields TRUE_OWNER1/2/3 cover up to three named owners. TRUE_SITE_ADDR is the formatted site address. TRUE_MAILING_ADDR1-3 holds the mailing address lines. Valuation fields include LAND_VAL_CUR, BUILDING_VAL_CUR, and TOTAL_VAL_CUR (all current-year). DOR_CODE_CUR and DOR_DESC identify the Florida Department of Revenue land-use classification. A sibling layer (Property @ PaGis, layer 24 of the same service) is a point layer with fewer fields -- use layer 26 for full attribute access. The MDPA portal at miamidade.gov/pa provides the authoritative full-record view including exemptions, appeals, and prior-year values not available on the REST layer. For folio-based lookups, the PA's PAPA search at miamidade.gov/pa/property_search.asp is publicly accessible.

Miami-Dade County's Parcels @ PaParcel layer exposes a parcel identifier (Folio Number), owner names (Owner Name (Primary), Owner Name 2, Owner Name 3), and address fields (Site Address, Site City, Site ZIP, Mailing Address). Use it for owner-name lookups and address-based parcel searches. All 8 listed fields accept queries. Served as an ArcGIS MapServer layer, which supports query operations but not write operations; last verified 2026-05-11.

The sample query above is a working example you can paste into a browser tab to see the raw JSON response.Counties publish parcel data through their own ArcGIS Server installations, each with its own schema. One county uses APN, another uses PIN, a third uses PARCEL_ID. Some expose owner names; others keep them on a separate assessor's portal. The searchable fields list above reflects what Miami-Dade County actually publishes — not what you might expect from a national standard (there isn't one).

Many county servers allow public reads but block browser cross-origin requests. The UrbanKit parcel lookup tool fetches directly from your browser; if it works there, the layer is technically public. For your own integration, you may need a same-origin proxy or server-side fetch.
Possibly — counties move services without warning. We re-verify entries weekly and flag stale ones. If you're seeing a fresh 404, please let us know and we'll update the listing.
Most are. Public ArcGIS layers don't typically rate-limit individual reads, but heavy programmatic use can trigger throttling at the host level. Be respectful — query what you need.
