Arizona’s new housing laws, HB2720 and HB2721, require cities to increase housing options by legalizing accessory dwelling units (ADUs) and allowing multi-family units near central business districts. Cities with over 75,000 residents must update zoning codes by January 2025 for ADUs and by January 2026 for multi-family units. Some cities, like Phoenix and Tucson, need to adjust existing rules, while others, like Peoria, must create new ones. Gilbert has limited the impact by designating a central business district, restricting multi-family development.
