Scottsdale FAQ
Does Scottsdale require me to live on the property to have an ADU?
No. Arizona Revised Statutes Sec. 9-461.18 (HB 2720) prohibits Scottsdale from requiring owner-occupancy as a condition for building or operating an accessory dwelling unit. Investor-owners may build and rent both the main house and the ADU to separate non-related tenants.
Can my Scottsdale HOA enforce owner-occupancy for ADUs?
HB 2720 (Ariz. Rev. Stat. Sec. 9-461.18) substantially limits HOAs from blocking ADUs that comply with the state by-right standards, particularly for covenants recorded after the statute's effective date. Older recorded covenants in established Scottsdale master-planned communities may be partially preempted; consult an Arizona real estate attorney for a specific CCR analysis.
Tempe FAQ
Does Tempe require owner-occupancy for ADUs?
No. Under Arizona HB 2720 (ARS 9-461.18), Tempe is preempted from requiring the property owner to live on-site as a condition of ADU permits or use. Both the main house and the ADU may be rented to separate tenants.
Can my Tempe HOA require me to live on-site to have an ADU?
Possibly, depending on your CC&Rs. ARS 33-1817 limits HOA provisions that effectively prohibit lawfully created ADUs, but reasonable architectural review and use restrictions may apply. Review your specific CC&Rs and consult an attorney before relying on or contesting an HOA owner-occupancy provision.
