Garage Construction · Humboldt County, California
In California, 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 (CA Codes) code (IRC 2024); apply through Humboldt Building Inspection before work begins.
