Finding a lot on the Beloit GIS map

The viewer Rock County publishes
Go first to the Rock County ArcGIS parcel map; it covers each tax parcel around Janesville and Brodhead. For a home near Brodhead, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. If the land is near Edgerton, write down the parcel ID from that panel; every office in the county uses it to find the file.
Beloit and the county around it
Beloit is part of Rock County, Wisconsin, which means parcel data comes from the county. For a tract near Footville, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the town limits near Footville generally answers to county rules, not municipal ones.
Where the recorded documents are
The map is an index, not the title: recorded deeds, plats and easements for land near Brodhead are filed with the Register of Deeds. Near Evansville, have ready the book and page shown in the record panel and the lookup takes minutes.

If the acreage or value on a parcel near Brodhead looks off go to the county real property listing office, since that office keeps the assessment data. Building or septic questions for a lot near Brodhead are for the local planning and health departments, and the answer depends on jurisdiction.
Keeping a record

Limits of the parcel data
