Do I need a permit for window or exterior door replacement in Unincorporated Pima County?
It depends. Whether window or exterior door replacement needs a permit in Unincorporated Pima County comes down to the details of your project.
Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule. In Pima County, permits outside the cities are handled by the Pima County Development Services Department, reachable on 520-724-9000 at https://www.pima.gov/970/Development-Services. Its online permit portal is https://publicworks.pima.gov/DSDPublicTools/. This office serves unincorporated Pima County. If your address sits inside a city or town, that municipality issues the permit instead. Ask whether a like-for-like swap is exempt at your address, since changing the size of an opening is structural work and is treated differently. Simple like-for-like replacement may not need a permit in some jurisdictions, but enlarging an opening, cutting a new opening, or altering an egress or bedroom window usually does. Rules vary because each Arizona city or county adopts its own code edition. Bedroom and basement windows must meet emergency escape and rescue (egress) sizing under whichever residential code edition your jurisdiction adopted. Arizona sets no statewide building code, so verify the local amendments before ordering units.
