Public ArcGIS FeatureServer endpoint for Dallas County parcel data. URL, supported fields, and a working sample query, copy it, or open it directly in the UrbanKit parcel lookup tool.
Beyond the parcel record, Dallas County has a free Dallas property report: code violations and building permits for an address, read straight from the city's open data.

41 fields confirmed including ACCT (17-digit DCAD account number), TAXPANAME1/2 (taxpayer names), TAXPAADD1-4, TAXPACITY, TAXPASTA, TAXPAZIP, ST_NUM, ST_NAME, ST_TYPE, ST_DIR, CITY, COUNTY, SCHOOL, SPTBCODE (special purpose district), PROP_CL, BLDG_CL, LEGAL_1-5, MAPSCO_GR, TOTEXEMPT, BUSNAME, PROPNAM, ResCom, APPRAISALYEAR. Owner search uses TAXPANAME1 (the taxpayer of record). APPRAISALYEAR in live records reads 2019. This is the snapshot vintage of the City of Dallas GIS's DallasTaxParcels layer, which sources from DCAD annual export. The authoritative real-time DCAD parcel lookup is at dcad.org; the gis.dallascounty.org REST server does NOT expose a public parcel service (only SampleWorldCities and CommissionerDistricts). This layer covers all of Dallas County, not just the City of Dallas city limits. CITY field contains the incorporated municipality (Dallas, Rowlett, Garland, Irving, etc.). The COUNTY field confirms 'DALLAS COUNTY' for all records. Texas Tax Code §25.025 (address-confidentiality program for protected persons, peace officers, judges, victims of family violence, etc.) may suppress some owner names in a future data refresh; query TAXPANAME2 as fallback. maxRecordCount=1000.

Dallas County's TaxParcels layer exposes owner names (Taxpayer / Owner Name (Primary), Taxpayer / Owner Name 2, Taxpayer Mailing Address 1) and address fields (Street Number, Street Name). Use it for owner-name lookups and address-based parcel searches. 8 of 14 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS FeatureServer layer, so edits and applyEdits operations are technically exposed (read access only is published here); last verified 2026-05-14.

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

services2.arcgis.com serves Dallas 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 Dallas County's FeatureServer layer on 2026-05-14. 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.
Dallas County's layer is hosted on Esri ArcGIS Online. Public ArcGIS endpoints rarely rate-limit individual reads, but services2.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.
