Accessory dwelling unit regulations
Summary
State law tweaks from 2025 forced Marana to revise its ADU rules, including how 'restricted-affordable dwelling units' are defined and when ADUs can be used as short-term rentals. Municipalities lost the fight to ban short-term rentals in ADUs, but newer ADUs used as short-term rentals must be owner-occupied. The rules take effect once Marana hits 75,000 residents.

Impact analysis
No direct cost to residents; the changes mainly affect what homeowners can build and rent on their lots.
Homeowners who want to add or rent out an ADU get clearer, state-aligned rules.
