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 San Augustine County. Our October 2026 check found the map open to the public, with no account or payment needed.
Searching for a parcel, step by step
- 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.
Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.

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.
