Where the parcel data comes from
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 Willacy County. Our October 2026 check found the map open to the public, with no account or payment needed.
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.
If an address search comes up empty, try the parcel number from a tax bill or deed instead, or click the lot on the map.

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.
