Travis County, Texas (Austin metro, pop. 1.3M, county seat Austin) is home to the state capital and the University of Texas at Austin. The REST layer ("TCAD Parcels", an ArcGIS Online hosted FeatureServer, ~386,682 parcels) is sourced from Travis Central Appraisal District (TCAD) and published through Travis County Transportation and Natural Resources (TNR) GIS. Searchable fields: PROP_ID (property ID), PID_10 (10-character parcel key), and SITUS (combined situs address). Owner name is NOT included. Travis County publishes the parcel geometry and identifiers as a public layer while keeping ownership data behind TCAD's property search portal at traviscad.org. For owner-name lookups, search traviscad.org by address or property ID. Texas Tax Code §25.025 permits certain persons (peace officers, judges, domestic violence victims, and similar categories) to request that their home address be withheld from appraisal records; such records may appear with address fields redacted at TCAD's portal. The county's former on-premise endpoint at gis.traviscountytx.gov/server1 went offline in 2026 (the ArcGIS host returned an HTTP 500 .NET host error); this hosted FeatureServer is the current public source. Open-data hub: tnr-traviscountytx.opendata.arcgis.com.

Travis County's TCAD Parcels layer exposes a parcel identifier (Parcel ID (10-char)) and address fields (Situs Address). Use it for address-to-PIN lookups and identifier queries. All 3 listed fields accept queries. Served as an ArcGIS FeatureServer layer, so edits and applyEdits operations are technically exposed (read access only is published here); last verified 2026-06-20.

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 Travis County actually publishes, not what you might expect from a national standard (there isn't one).

services.arcgis.com serves Travis County, Texas parcels over public ArcGIS REST, but, like most county servers, it may not send the CORS headers a browser needs for a cross-origin fetch. If a direct browser call fails, the layer still works from curl, Postman, or a server-side script; the UrbanKit parcel lookup tool proxies the request, so a search that succeeds there confirms the layer is genuinely public.
We last verified Travis County's FeatureServer layer on 2026-06-20. County GIS teams move services without notice, so if you hit a fresh 404, tell us and we'll re-check. Atlas entries are re-verified on a rolling basis.
Travis County's layer is hosted on Esri ArcGIS Online. Public ArcGIS endpoints rarely rate-limit individual reads, but services.arcgis.com can throttle heavy automated traffic at the host level. Page through results with resultOffset / resultRecordCount and request only the fields you need. There's no API key and no charge from the county.
