In Unincorporated Wayne County, permits and inspections are handled by the city or town building department, or by the county for unincorporated areas; the state Division of Professional Licensing administers the code but does not issue permits or inspect. The adopted IRC list of work exempt from permit (Section R105.2, as amended by Utah Code 15A-3-202) applies statewide, covering items such as one-story detached accessory structures of 200 square feet or less, fences up to 7 feet, sidewalks and driveways, finish work, and low decks. Zoning rules such as setbacks and height limits still apply to exempt work, so confirm with the building and planning office that has jurisdiction over your address in Unincorporated Wayne County before you start.
