How are inspections scheduled?
The county portal directs applicants to check with the applicable town for administrative and building-permit/UDC requirements; arrange building-code inspections with that town or its contracted inspector. For county zoning questions or site-review coordination, call 920-674-7130.
Which codes and exemptions should I review?
Jefferson County zoning and land-use regulations, including county shoreland and floodplain requirements, apply where the county has jurisdiction. Building permits and Wisconsin Uniform Dwelling Code requirements are administered separately by the applicable town or municipality. No county zoning permit is required for ordinary nonstructural maintenance such as painting, decorating, paneling, shingling, siding, or replacement of doors, windows, and other nonstructural components. Structural changes, including changes to foundations, bearing walls, columns, beams, girders, or window/door dimensions, require review.
