Free parcel data in Utah

Yes. Utah publishes a free statewide parcel layer: Utah Statewide Parcels (Basic Parcels), from Utah Geospatial Resource Center (UGRC, formerly AGRC). Coverage: All 29 counties. It's a public ArcGIS REST service with no API key or login.

Notes for GIS users

County values are names without spaces (SaltLake, BoxElder, SanJuan). PARCEL_ID formats differ by county (Salt Lake 14 digits, Utah County 9). Roads/ROW are not parceled, so a point on a street returns 0 features. Attributes are basic only (no owner name); per-county LIR layers under the same org carry more.

How to use it

QGIS: Layer > Data Source Manager > ArcGIS REST Server, add a connection with the service URL (the endpoint above without the final /0), then add the layer. Filter to your area before exporting.
ArcGIS Pro: Add Data > Data From Path, paste the endpoint.
Direct query: append /query?geometry=LON,LAT&geometryType=esriGeometryPoint&inSR=4326&spatialRel=esriSpatialRelIntersects&outFields=*&f=geojson to get the parcel at a point.
CAD: see getting a parcel into AutoCAD or Civil 3D.

Assessor parcel lines are for taxation and are often 5 to 50 ft off the legal boundary. Why.

Basesheet uses this to draw the parcel line on a base plan for any Utah address, with LiDAR contours, soils, flood zones and wetlands.
