Arizona building departments

This Arizona directory covers 15 Census county equivalents and local building-department guides. Cities and counties commonly control permit intake and local amendments. Start with the jurisdiction where the project is located rather than assuming a county-wide office.

How permitting works in Arizona

Primarily local adoption and administration. A county name is a geographic index, not a promise that the county government issues every building permit. Many projects are handled by a city, town, township, borough, parish, regional office, or independent city.

Arizona building codes are primarily adopted and enforced by local governments. State law provides a fallback for public buildings in areas without adopted local codes, using the state fire code and applicable building codes of the largest city in the county.
