Arizona has NO statewide building code. Home Rule state - municipalities adopt independently. Most jurisdictions on 2018 I-Codes. Phoenix adopted 2024 PBCC (Ordinance G-7347, effective Aug 2025) with cool roof mandates and EV readiness. State preemptions: Office of Manufactured Housing (OMH), State Fire Marshal (OSFM). Pool barriers statewide via A.R.S. 36-1681 (60-inch height). ROC licenses contractors statewide.
