Do I need a permit for shed or accessory structure in Tucson?
It depends. Whether shed or accessory structure needs a permit in Tucson comes down to the details of your project.
Small accessory structures under a size threshold are often exempt from a building permit, but the threshold and setback rules differ by jurisdiction because Arizona has no statewide code; Phoenix, Maricopa County, Tucson, and Pima County each set their own limits. A permit exemption does not waive zoning setbacks, HOA rules, or an electrical permit if the shed will be wired. Tucson generally exempts a small, unoccupied accessory building (commonly up to 200 square feet) with no utilities from a building permit, but the structure must still meet the Unified Development Code setback, height, and yard limits, so an exempt shed is not exempt from zoning. Adding electrical, plumbing, or gas to a shed, or making it occupiable such as a casita or ADU, moves it into permitted work with its own trade permits. Independent guidance only; verify the current size threshold and setbacks with PDSD before you build, and check any HOA CC&Rs, which the city does not enforce. A shed that will have electricity, plumbing, or a permanent foundation falls outside the usual small accessory building exemption, which generally covers simple unpowered structures only. Electrical and plumbing work each normally require their own permit and inspection even when the structure itself would have been exempt, and many jurisdictions require a licensed electrician or plumber to pull them. Zoning setbacks, height limits, and lot coverage are reviewed separately from the building permit, so confirm placement with your local department before the shed is delivered or poured.
