Duncan, 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 (A.R.S. Title 9 for municipalities). The Town of Duncan is a small incorporated town that runs its own building-permit program directly out of Town Hall (the Town Manager's office functions as Building Official) rather than deferring to Greenlee County; this is confirmed by the Town's own Building Permits & Fees page, its Chapter 7 (Building) town code chapter, its Schedule of Fees and Charges, and its paper 'Application for Building Permit and Inspection' form, all of which are Duncan's own documents (not county documents).

Not the Town of Duncan — the Duncan Valley Rural Fire District (DVRFD), a separate special taxing district, requires and reviews permits for fire sprinkler systems, fire alarm systems, fire hydrant systems, and commercial hood systems under the 2018 International Fire Code plus DVRFD amendments. This is in addition to the Town's own Building Permit, not a replacement for it.
