What the Trempealeau County records include

Counties fill in the statewide schema differently. This is how complete Trempealeau County’s 2025 records are:

Trempealeau County parcel records with each field filled in
Field	Filled in
Owner name	96.1% of parcels
Site (street) address	40.3% of parcels
Assessed or estimated value	83.6% of parcels
Assessed or deeded acres	83.9% of parcels

Only 40.3% of parcels have a street address, which is normal for rural land: fields and woods often have no house number. Search by owner name or parcel ID to find those.

In WI 2026, color the map by Auxiliary Class of Property to see these parcels, and tap one for the owner and acreage. The acreages are whole-parcel areas from the tax roll: a parcel that is only partly enrolled counts in full, and the tax roll doesn’t show posted areas or access routes. Before you hunt, check the DNR’s map of private forest land open to the public and the signs on the ground.
