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. The Texas SB247 privacy flag may suppress some owner names in a future data refresh; query TAXPANAME2 as fallback. maxRecordCount=1000.

/query?where=…&outFields=*&f=jsonto the URL. 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 this 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.
