Who runs this map
In Texas, property values are set by appraisal districts rather than by the county government, so this map comes from the appraisal district that serves Karnes County. As of our October 2026 test, anyone could open it without signing in or paying.
Finding a property on this map
- Open the link. In Texas, each county's appraisal district (CAD) values property for local taxing units, and this is the CAD's public map.
- Search by owner, address or property ID. The property ID is the account number the CAD uses on its records.
- Click a parcel on the map to bring up its account summary.
- Use the account details to look up values or the full appraisal record on the CAD's site.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.
