Garage Construction · Olmsted County, Minnesota

A garage almost always requires a building permit. Attached garages always need one; a detached garage is exempt only if it is under 200 sq ft with no electrical, which most garages exceed. Plans are reviewed under the Statewide code (IRC 2018); apply through Olmsted County Building Permit before work begins.
