Arizona has no statewide energy code, and Maricopa County has not adopted a cool-roof ordinance for unincorporated areas. The county follows the 2018 International Residential Code with limited energy provisions, leaving roof-reflectance choices to the property owner.
ARS section 41-2192 invites but does not require Arizona local governments to adopt the International Energy Conservation Code. Maricopa County Planning and Development has adopted the 2018 IRC and IBC for unincorporated areas, but skipped most IECC chapters and any cool-roof reflectance or emittance requirement. There is no county solar reflectance index minimum, no required ENERGY STAR roofing, and no white or reflective surface standard. Phoenix, Tempe, Mesa, and Chandler have stronger residential energy provisions inside city limits, including limited cool-roof or radiant-barrier requirements in newer subdivisions. Unincorporated builders may earn voluntary credit through the EPA ENERGY STAR program but face no county mandate.
Because Maricopa County has not adopted a cool-roof ordinance, there are no specific code citations or fines tied to roof reflectance. Standard building permit and inspection penalties apply if any roofing work is done without a permit.
