The resources below list the active rules for each Arizona state agency. Data regarding the number of rules each agency has, along with the original authority for each rule are available for analysis. Rule authority is assigned to one of the following categories: agency discretion, state statute, federal statute, or definitions/applicability. Additional information can be found in the definitions and methodology document.
Arizona state agency rules are frequently improved or eliminated based on the changing needs of the state. These rule changes oftentimes have positive impacts on working professionals and business establishments within the state. OEO calculates the administrative cost savings generated from improving or eliminating agency rules.
