accessory dwelling units; requirements.

This Arizona bill mandates that cities with over 75,000 residents must allow homeowners to build attached and detached accessory dwelling units on their property. It sets specific rules for these units, such as limiting their size to 75% of the main home's area or 1,000 square feet, and requires them to be permitted without needing special approvals. The law also restricts local governments from imposing certain conditions, such as demanding familial relationships between owners and tenants, requiring extra parking, or forcing units to match the exterior design of the primary home. Additionally, the bill preempts local control over vacation rentals by prohibiting cities from banning them entirely, though it allows for basic health, safety, and zoning regulations.
