Arizona Building Code Overview

Building permit requirements in Arizona are established and enforced at the municipal level, meaning each city sets its own rules for when permits are required, how much they cost, and what the application process looks like. While Arizona may adopt a statewide building code (such as the International Building Code or International Residential Code), individual cities can and do modify these codes with local amendments.

Common projects that require permits across most Arizona cities include: sheds and accessory structures over 100-200 square feet, attached decks and decks elevated over 30 inches above grade, swimming pools and hot tubs with electrical connections, garages, ADUs (accessory dwelling units), and fences exceeding local height limits. Even projects that do not require a building permit must typically comply with zoning setback requirements.

Before starting any construction project in Arizona, contact your local city building department to verify current requirements. Permit rules change frequently, and building without a required permit can result in fines, required demolition, and complications when selling your home.
