The Phoenix City Council adopted the 2024 Phoenix Building Construction Code, Ordinance G-7397, on June 18, 2025, replacing the existing construction code. This comprehensive update integrates 15 model codes from national bodies like the International Code Council (ICC), National Fire Protection Agency (NFPA), International Association of Plumbing and Mechanical Officials (IAPMO), and American Society of Mechanical Engineers (ASME), along with city-specific amendments. The changes reflect current trends, safety advances, and new technologies, including provisions for electric vehicle charging infrastructure, reduced water consumption, inclusive home design, eased refrigerant installation in multi-family developments, and compliance with revised Arizona Statutes. The code adoption process involved extensive public input and reviews by various boards and subcommittees, ensuring alignment with local conditions and practices, such as requiring minimum cooling standards due to Phoenix's climate.
