Free parcel data in Arkansas

Yes. Arkansas publishes a free statewide parcel layer: Parcel Polygon - County Assessor Mapping Program (CAMP), from Arkansas GIS Office (AGISO). Coverage: All 75 counties. It's a public ArcGIS REST service with no API key or login.

Notes for GIS users

maxRecordCount is only 200, so page with resultOffset for area queries. countyfips is the 3-digit county FIPS as a string (119 = Pulaski); county holds the name. camakey (numeric) is the CAMA link, not a user-facing parcel number. adrlabel can contain double spaces.

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 Arkansas address, with LiDAR contours, soils, flood zones and wetlands.
