accessory dwelling units; codes; owners

Arizona's SB 1110 requires cities with populations over 75,000 to allow accessory dwelling units (ADUs) on single-family residential lots. It mandates that municipalities permit at least one attached and one detached ADU per lot, with additional options for larger lots (one acre or more) and affordable units, while prohibiting restrictions like design matching, extra parking fees, or relationship requirements between owners and tenants. The bill sets a maximum ADU size (75% of the main home's floor area or 1,000 square feet) and requires cities to adopt these rules by January 1, 2025, or ADUs will be allowed without limitations on residential properties. It does not apply to tribal lands, military areas, or airport zones.
