This bill proposes updates to section 9-461.18 of the Arizona Revised Statutes regarding accessory dwelling units (ADUs). The current law mandates that municipalities with a population over seventy-five thousand must adopt regulations allowing ADUs on lots where single-family dwellings are permitted. The bill modifies this requirement by stipulating that if a municipality's population exceeds seventy-five thousand as determined by the most recent U.S. decennial census, it must adopt the necessary regulations within six months. If it fails to do so, ADUs will automatically be permitted on all residentially zoned lots within that municipality.

Additionally, the bill clarifies that the provisions apply specifically to municipalities with populations over seventy-five thousand and retains existing exemptions for certain land types, such as tribal land and areas near military or public airports. It also updates definitions within the statute, changing "shall be" to "is" for restricted-affordable dwelling units and replacing "determination" with "determine" in the context of permitted uses. Overall, these changes aim to streamline the process for municipalities to comply with ADU regulations while ensuring that the law remains applicable to larger populations.
