Garage Construction · Johnson County, Indiana
In Indiana, a Garage Construction requires a building permit.
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 Johnson County Planning/Zoning before work begins.
