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).

Dewey-Humboldt runs its own independent Building Safety Division within its Community Development Department, with a named Building Official (Marty Joanou) and Permit Technician (Rio Cochran); it does not contract building-permit administration to Yavapai County. However, the Town's building permit FEES are calculated using Yavapai County's own Valuation and Fee Schedule as a pass-through, with the Town adding a flat 42% administration surcharge — and septic-system permitting is separately and exclusively handled by Yavapai County, a mandatory prerequisite before Town plan review begins.
