Permitting processes vary by municipality; understanding local zoning ordinances and building codes in Green Bay and Kenosha is essential. The state's common housing stock, predominantly single-family homes, provides a solid foundation for ADU integration, but requires attention to detail to ensure structural compatibility and aesthetic harmony.
