Dewey-Humboldt, Arizona has adopted: Arizona has NO statewide mandatory building code floor for general construction — code adoption is a per-city/county authority under state enabling statutes (e.g., A.R.S. Title 9 for municipalities). The Town of Dewey-Humboldt (incorporated 2004 from the merger of the unincorporated communities of Dewey and Humboldt) runs its own independent Community Development Department / Building Safety Division and independently adopts and administers its own construction codes under Chapter 150 (Building Codes) of the Dewey-Humboldt Code of Ordinances; it does NOT contract the building-permit function to Yavapai County.
