Do I need a permit for shed or accessory structure in Gilbert?
It depends. Whether shed or accessory structure needs a permit in Gilbert 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. Gilbert follows the International Residential Code exemption pattern, where a small detached one-story accessory building (commonly 120 square feet or less) with no utilities may not need a building permit, but a permit is required if the shed has electrical, plumbing, or mechanical connections or is connected to the house; confirm the exact size threshold with Development Services at (480) 503-6700. Even a permit-exempt shed must still meet Gilbert's zoning setback, height, and lot-coverage rules in the Land Development Code, so verify placement before you build. Call Arizona 811 before digging any post holes or footings; Gilbert's residential permits and checklists are handled through the One Stop Shop portal. 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.
