Brown County runs this viewer (directly or through a contracted vendor), which makes it the closest thing to the source for local parcel lines. 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 official link. The viewer is built with ArcGIS Web AppBuilder; if a disclaimer pops up, accept it to continue.
- Use the search widget, usually in the upper left, to find a street address or parcel ID.
- Click a parcel to open its info window.
- The widget bar holds extras such as the layer list, basemap switcher, measure and print tools.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.

Before you rely on the lines
Treat the map as a guide, not a boundary survey: parcel outlines are often shifted a bit from the real corners. A licensed surveyor settles exact lines.
