Arizona's predominantly arid to semi-arid climate, characterized by intense summer heat, minimal rainfall, and significant diurnal temperature variations, demands building materials with high thermal resistance, effective passive cooling strategies, and robust UV protection for exterior finishes. While Arizona has made strides in standardizing ADU regulations statewide, local ordinances in cities like Tucson and Scottsdale still play a crucial role in dictating specific requirements concerning setbacks, lot coverage, and parking. Accessory Dwelling Unit Pros ensures comprehensive adherence to both state guidelines and municipal codes for all projects.
