WISCONSIN COUNTY PARCEL MAPS
Columbia County parcel map and property owners
WI 2026 puts all 43,719 parcels in Columbia County on your phone: owner names, site addresses, assessed values and acreage from the county’s 2025 tax roll. The county download is about 12 MB, and once it’s on your phone you can search it and tap any parcel with no signal.
The parcels cover 496,613 mapped acres across 35 towns, villages and cities, and 15 school districts. The most parcels are in the City of Portage. The data is the State Cartographer’s Office V12 statewide parcel map, loaded from the county on March 3, 2026.

What the Columbia County records include
Counties fill in the statewide schema differently. This is how complete Columbia County’s 2025 records are:
| Field | Filled in |
|---|---|
| Owner name | 99.1% of parcels |
| Site (street) address | 58.3% of parcels |
| Assessed or estimated value | 89.1% of parcels |
| Assessed or deeded acres | 94.9% of parcels |
| Net property tax | 89.1% of parcels |
Only 58.3% 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.
How the land is classed
By mapped area, Columbia County is agricultural 60%, residential 15%, government-owned / county forest 9%, undeveloped / ag forest 8%. The median estimated fair market value of a residential parcel is $274,400, across 21,576 residential parcels with a value.
In WI 2026, open the legend and color the map by Class of Property to see the same picture, or by Estimated Fair Market Value to see where values rise and fall.
Deer season: public land and Managed Forest Law
The tax roll marks parcels that are government-owned or enrolled in Wisconsin’s forest tax programs. In Columbia County:
- Federal-owned: 3,913 acres in 132 parcels
- State-owned: 25,574 acres in 1,048 parcels
- County-owned: 1,021 acres in 277 parcels
- Managed Forest Law, open to public hunting, fishing, hiking, sightseeing and cross-country skiing: 138 acres in 5 parcels
- Managed Forest Law, closed (no public access without permission): 29,562 acres
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.

Where the data comes from
Parcel data is the Wisconsin Statewide Parcel Map Database (V12), a public-domain product of the Wisconsin Land Information Program and the State Cartographer’s Office, UW–Madison, built from Columbia County’s 2025 tax roll. It is a snapshot, not a live feed: for a sale, a survey or a tax question, check with Columbia County directly.
