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.

Salt Lake County's Parcels_SaltLake_LIR layer exposes a parcel identifier (Parcel ID (Serial Number)) and address fields (Parcel Address). Use it for address-to-PIN lookups and identifier queries. 4 of 12 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 2026-05-15.

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

services1.arcgis.com serves Salt Lake County, Utah 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 Salt Lake County's FeatureServer layer on 2026-05-15. 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.
Salt Lake County's layer is hosted on Esri ArcGIS Online. Public ArcGIS endpoints rarely rate-limit individual reads, but services1.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.
