Flagstaff, Arizona has adopted: Arizona has no mandatory statewide building code edition — cities and counties each adopt and amend their own codes (per Arizona Revised Statutes framework for municipal building regulation; no state building-code-adoption agency parallel to Montana's DLI exists). The City of Flagstaff independently administers its own Building Safety program within city limits, separate from Coconino County's building department, which handles unincorporated county areas.
