About the official source
The source here is the Delta County appraisal district. Texas law gives these districts the job of valuing property for every local taxing unit in the county. Our October 2026 check found the map open to the public, with no account or payment needed.
How to use the Delta 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.

Before you rely on the lines
The lines you see online are approximate. They're good for finding a lot and its parcel number, but a legal boundary question needs the recorded plat or a surveyor.
