ADU Rules
The City of Mosinee's Zoning Code (originally updated in 1998) is administered by the City Clerk's office and Building Inspector and codified in the Code of Ordinances on Municode. Mosinee has not adopted a stand-alone accessory dwelling unit (ADU) chapter; instead, additional dwelling units are governed by the underlying residential zoning district standards (single-family, two-family, multi-family) plus accessory use and accessory structure provisions. A second dwelling unit on a single-family lot generally is not a permitted accessory use unless the lot meets the density, lot area, and dimensional requirements of a two-family or multi-family district. Building permits and zoning permits are required and issued through the City of Mosinee Building Permits process.
