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 removes the specific population threshold for municipalities to adopt these regulations, instead requiring that if a municipality's population exceeds seventy-five thousand as determined by the most recent U.S. decennial census, it must implement the regulations within six months. If the municipality fails to do so, ADUs will be allowed on all residentially zoned lots.

Additionally, the bill clarifies that the section applies specifically to municipalities with populations over seventy-five thousand and modifies definitions related to permitted uses and restricted-affordable dwelling units. The term "permitted use" is updated to specify that it allows for development approval without the need for public hearings or special permits, while the definition of "restricted-affordable dwelling unit" is revised to indicate that such units are rented to households earning up to eighty percent of the area median income. Overall, the bill aims to streamline the process for municipalities to adopt regulations for ADUs and ensure compliance following population changes.
