Garage conversion rules in Milton, WI — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Rock County has no single garage-conversion ordinance. Turning a garage into living space creates a dwelling unit subject to your town, village or city zoning plus the Wisconsin Uniform Dwelling Code for habitable-space standards.
Converting a garage into living or rental space is regulated locally, not by a county-wide rule. In unincorporated towns with county zoning, the change is reviewed under Wis. Stat. 59.69 standards (lot coverage, off-street parking, and whether a second dwelling unit is allowed in the district). Inside cities and villages, the municipality reviews it. Regardless of location, converting a garage to habitable rooms must meet the Wisconsin Uniform Dwelling Code (egress, ceiling height, insulation, smoke alarms) and usually requires a building permit. Losing required off-street parking or creating an unpermitted dwelling unit are the common sticking points.
An unpermitted conversion can be ordered reversed, and creating an illegal dwelling unit may draw daily zoning forfeitures under the local ordinance.
