residential building materials; requirements; prohibition

HB 2317 prohibits Arizona municipalities from banning approved building materials in single-family home construction or imposing extra restrictions on prefabricated homes compared to traditional homes. It also limits aesthetic regulations to designated historic districts, while allowing existing building, fire, and safety codes to remain in effect. The bill directly affects homeowners, builders, and local governments by preventing new restrictions on material choices and ensuring prefabricated homes face the same requirements as site-built homes. The bill failed during committee review on January 29, 2025.
