Updated 3/15/2025
Overview
Arizona does not have a statewide building code; instead, code adoption is determined at the
local level. Each city or county establishes its own regulations, meaning the codes listed below
may not apply in all jurisdictions. However, there are some statewide minimum codes for
specific areas:
- The Arizona Department of Health Services adopts a minimum code for licensed health care facilities statewide.
- The Arizona Department of Housing establishes minimum codes for manufactured housing.
- The Arizona Office of the State Fire Marshal enforces a statewide fire code, currently the 2018 International Fire Code (IFC).
To determine applicable codes in a specific area, contact local building departments.

Local Adoption
A local adoption model means that the state does not mandate uniform building codes,
leaving code adoption and enforcement entirely to local jurisdictions. Cities and counties
determine which codes to implement, leading to potential variations in regulations across
different areas within the state.
