Williams, 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). The City of Williams runs its own independent Building Department and adopts and administers its own construction codes; it does not defer building permitting to Coconino County.

No corresponding new numbered ordinance repealing/replacing Ordinance No. 956 was found published in the American Legal Publishing code library or via Wayback Machine as of July 2026, but the City's own current-facing submittal-requirements document (undated but filename '2024 Design Criteria.pdf', hosted directly under the Building Department page alongside a 2024-cycle Solar Policy and 2025-dated fillable permit application forms) is the most current, most directly-published statement of which code edition the City is actually enforcing for new submittals as of this writing. Both the 2015-cycle codified ordinance and the 2024-cycle submittal-requirements sheet are cited throughout this record; where they conflict, the 2024 Design Criteria document is treated as controlling for current practice, with the codified Ordinance No. 956 amendments (administrative sections, fee/refund cross-references, permit expiration rules) still applicable since no repeal was found.
