How to use the Franklin County viewer
- 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.
