Do I need a permit for addition or structural alteration in Phoenix?
Yes. In Arizona, addition or structural alteration generally requires a permit, and Phoenix is no exception.
Additions that change the building footprint require full plan review and typically involve zoning, setback, and structural review; scope and submittal lists vary by the city or county code edition adopted. Owner-builders acting under ARS 32-1121 may perform work on a home they occupy, but selling or renting it within one year is prima facie evidence it was built for sale, which removes the exemption. Room additions require two sets of building plans plus a completed Construction Permit / Plan Review Application submitted to the residential permit counter; only minor alterations may qualify for an over-the-counter permit. Grading and drainage or hillside permits, if required, must be obtained before the building permit is issued.
