Summary
Converting a garage into living space requires a city building permit and must comply with zoning. Coon Rapids requires each dwelling to keep at least 484 square feet of garage/storage accessible to vehicle storage (minimum 22 by 22 feet), so eliminating that required parking blocks a full conversion.
At least 484 square feet of floor area of garage/storage structure per dwelling must be accessible to vehicle storage, which must have a minimum width of 22 feet and a minimum depth of 22 feet.
Full Breakdown
Garage conversions are handled by your city building and zoning departments, not Anoka County. In Coon Rapids, every dwelling must retain at least 484 square feet of garage/storage floor area accessible for vehicle storage, at least 22 feet wide and 22 feet deep. Converting the required garage to a bedroom or apartment removes that mandated vehicle storage and is generally not allowed unless replacement garage space is built. Any conversion adding habitable space triggers a building permit and must meet the Minnesota Residential Code for egress windows, ceiling height, insulation, smoke and carbon monoxide alarms. It also cannot create an unpermitted second dwelling unit in a single-family district.
Violations & Fines
Finishing a garage into living space without permits is a code violation; the city can require the work be brought to code or reversed, deny occupancy, and levy fines.
