Arizona Administrative Code

The Arizona Administrative Code (A.A.C.) is the publication of regulatory rules adopted by Arizona agencies. The A.A.C. was published in its entirety in 1974. It is organized into Titles by topic and further divided into Chapters, Articles, and Sections. The current A.A.C. is published on the website of the Arizona Secretary of State.

Amendments to the A.A.C. and repeal of its provisions are made by numbered Supplements. Researchers consult the Supplements to learn when a particular provision was adopted, amended, or repealed and to read changes in the text of a rule.
