Ordinary repairs may be exempt when they do not affect structural members, required egress, or regulated plumbing, electrical, mechanical, public-health, or general-safety systems; confirm with the county inspector before starting. Certain agricultural buildings are outside the Michigan construction-code definition of building. A permit is generally required for most construction, additions, alterations, and trade work.
