About the official source
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 Madison County. Our October 2026 check found the map open to the public, with no account or payment needed.
How to use the Madison 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.
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
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.
