30 fields confirmed including PARCEL_ID, COUNTY_NAME, COUNTY_ID, ASSESSOR_SRC, BOUNDARY_SRC, CURRENT_ASOF, PARCEL_ADD, PARCEL_CITY, TAXEXEMPT_TYPE, TAX_DISTRICT, TOTAL_MKT_VALUE, LAND_MKT_VALUE, PARCEL_ACRES, PROP_CLASS, PRIMARY_RES, HOUSE_CNT, SUBDIV_NAME, BLDG_SQFT, FLOORS_CNT, BUILT_YR, EFFBUILT_YR, CONST_MATERIAL, PROP_TYPE. Query confirmed: returns real Salt Lake City addresses with market values. NOTE: Owner name is NOT included in this public LIR (Land Information Record) layer — owner data is available through the Salt Lake County Assessor's Parcel Viewer at apps.saltlakecounty.gov/assessor/new/ParcelViewer/. PARCEL_ID is the 14-digit serial number. This dataset is maintained by UGRC (Utah Geospatial Resource Center) in coordination with the Salt Lake County Assessor; data is updated monthly. A basic geometry-only version (Parcels_SaltLake) also exists on the same service with 17 fields and no value data.

/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.
