Zoning Data

July 13, 2017

Zoning in Wisconsin varies by type, class and authoritative jurisdiction. Zoning type and zoning class definitions may also vary between jurisdictions, making them potentially incompatible with one another.  For this reason, zoning can be difficult to seamlessly aggregate at regional and statewide scales and it is generally best to contact the authoritative jurisdiction for the most complete zoning data.

Parcel Data

GIS parcel data in Wisconsin is created and maintained at both the municipal and county levels. For the majority of Wisconsin counties, parcel data is regularly aggregated from municipal to county-wide datasets if the parcels are not originally created by the county. Some exceptions to this include the Cities of Eau Claire, Beloit, Antigo, and Janesville, where parcel data remains available only at the municipal level. There are also areas of the state that are not yet digitally parcel mapped.

Platbooks and Land Ownership Maps

Plat books make use of the Public Land Survey System to represent land ownership patterns on a county-by-county basis. They are a convenient reference for local governments, private realty, surveying companies, and the general public. Commercial plat books for Wisconsin are generally prepared by private map publishing companies in conjunction with county governments. However, many Wisconsin counties have begun to produce and update the maps themselves.
