Tarrant County, Texas (Fort Worth / Arlington metro, pop. 2.1M, county seat Fort Worth) is the fourth-most populous Texas county. The data authority is TAD — Tarrant Appraisal District. 56 fields confirmed including TAXPIN, ACCOUNT, OWNER_NAME, SITUS_ADDR, OWNER_ADDR, OWNER_CITY, ZIPCODE, DEED_DATE, DEED_BOOK, DEED_PAGE, YEAR_BUILT, LIVING_ARE, BEDROOMS, BATHROOMS, SW_POOL, LAND_ACRES, APPRAISEDV, LAND_VALUE, IMPR_VALUE, and TOTAL_VALU. Owner-name query via UPPER() LIKE on OWNER_NAME returns real results. Texas Tax Code §25.025 (address-confidentiality program) permits certain protected persons — peace officers, judges, domestic violence victims, and similar categories — to request that their address be withheld from public appraisal records; records subject to §25.025 may not appear in REST query results or may appear with address fields suppressed. A sibling TADParcelsApp/MapServer/0 exists on the same server but carries only TAXPIN geometry — it is the display layer for TAD's parcel viewer and has no attribute data. TAD open-data hub: gis-tad.opendata.arcgis.com. Tarrant County open data: data-tarrantcounty.opendata.arcgis.com.

Tarrant County's Tarrant County Parcel layer exposes a parcel identifier (Tax Parcel ID), owner names (Owner Name, Owner Mailing Address, Owner City), and address fields (Situs Address, Situs ZIP Code). Use it for owner-name lookups and address-based parcel searches. All 7 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 Tarrant County actually publishes — not what you might expect from a national standard (there isn't one).
For background, see What is an APN?
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.
