About the official source
Texas splits the job: an appraisal district, not the county itself, values each property. This viewer belongs to the district covering Gaines 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.
Have a tax bill handy? The parcel or account number on it is usually the fastest way to search.

A note on accuracy
Keep in mind that a GIS parcel layer is a tax map, not a survey. For exact boundaries, look at the recorded deed and plat or hire a licensed land surveyor.
