Who runs this map
Texas splits the job: an appraisal district, not the county itself, values each property. This viewer belongs to the district covering Knox County. When we tested the link in October 2026 it opened with no login and no fee.
How to use the Knox County viewer
- 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.

A note on accuracy
Treat the map as a guide, not a boundary survey: parcel outlines are often shifted a bit from the real corners. A licensed surveyor settles exact lines.
