The proposed bill amends Arizona Revised Statutes to allow municipalities and counties to adopt ordinances for the development of accessory dwelling units (ADUs) in areas zoned for single-family or multifamily use. The ordinances must designate specific areas where ADUs are permitted, impose standards such as parking, height, setbacks, and landscaping, and ensure that the ADUs do not exceed the allowable density for the lot. Notably, the bill prohibits requirements for minimum lot size and mandates that municipalities and counties act on permit applications within sixty days if there is an existing dwelling on the lot.

Additionally, the bill defines an "accessory dwelling unit" as a residential unit that provides independent living facilities and is located on the same lot as a primary residence. It specifies that ADUs cannot be sold separately from the primary residence, can be either attached or detached, and sets size limitations for both attached (maximum of 50% of the primary dwelling's size) and detached units (maximum of 1,200 square feet). Overall, the bill aims to streamline the approval process for ADUs while maintaining certain standards and restrictions.
