Do I need a permit for addition or structural alteration in Gilbert?
Yes. In Arizona, addition or structural alteration generally requires a permit, and Gilbert 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. A room addition or structural alteration increases floor area and building systems, so Gilbert requires a residential permit and plan review submitted electronically through the One Stop Shop portal following the Town's Residential Addition, Alteration & Accessory Checklist. Gilbert requires foundation certification (including post-tension slab certification for one and two family dwellings) on many residential projects, so plan for that documentation early. Confirm zoning setbacks and lot coverage in the Land Development Code before designing; Gilbert enforces its own adopted 2018 International Codes with local amendments because Arizona has no statewide building code.
