self-certification program; administrative review

HB 2447 creates a self-certification program for Arizona cities and towns, allowing licensed architects and engineers to certify that construction projects meet building codes without full city review. The law enables local governments to eliminate public hearings for certain administrative approvals (like site plans and design reviews) and offers expedited permit processing for applicants with strong compliance records. It requires that all standards be "objective" and verifiable, meaning decisions must rely on clear benchmarks, not personal judgment. This bill directly affects local building permit processes, reducing administrative delays for qualifying projects while shifting responsibility to certified professionals. The law was signed by the governor on March 31, 2025, making it effective immediately.
