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 Gillespie County. When we tested the link in October 2026 it opened with no login and no fee.
Finding a property on this map
- Press the button above to open the appraisal district's map. Texas appraisal districts set taxable values, so their maps tie each parcel to a property account.
- Look up a property by its owner, situs address or property ID.
- Click any lot to see the account number and basic details.
- Follow the record link, when there is one, for values and exemptions.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.

Maps vs. surveys
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.
