Arizona's approach to ADUs is largely decentralized, with individual municipalities like Tucson, Chandler, and Scottsdale establishing their own zoning codes and permitting processes. While there isn't a statewide mandate, many cities have recognized the value of ADUs in addressing housing needs and have implemented regulations that permit their construction. These regulations typically specify requirements for setbacks, lot coverage, height limitations, and parking. Given the intense heat and significant solar exposure characteristic of Arizona's climate, the selection of appropriate building materials, insulation strategies, and HVAC systems is paramount to ensure energy efficiency, occupant comfort, and the long-term structural integrity of the ADU.
