Full Breakdown
Turning a garage into living space, an office or an ADU is governed by your city, not Ramsey County. Under the Ch. 462 zoning enabling statute, cities set the density, use and building standards. In St. Paul, converting a detached garage into habitable space generally makes it an accessory dwelling unit under Sec. 65.913, subject to the 800-sq-ft / 25-foot-height ADU limits, and any conversion requires building permits for structural, egress, insulation and electrical work. Many cities also require replacement off-street parking if the garage stalls are lost. Confirm requirements with the city where the property sits.
Violations & Fines
Unpermitted garage conversions are municipal code violations. Cities can require permits after the fact, order the space returned to a garage, deny occupancy, and impose fines.
