How do adu owner occupancy rules compare between Surprise, AZ and Tempe, AZ?
Surprise and Tempe have similar restriction levels.
Surprise, AZ
Maricopa County
Under Arizona's ADU statute (ARS § 9-461.18) Surprise cannot require owner occupancy of the principal dwelling or the ADU for long-term rental purposes. The statute also prohibits any familial, marital, or employment relationship requirement between owner and occupant. The only owner-occupancy authority remaining is for ADUs built after September 14, 2024, that are used as short-term rentals — Surprise can require the owner to live on-site in that narrow scenario.

Tempe does not require owner occupancy for ADUs. Arizona HB 2720 (ARS 9-461.18) prohibits cities over 75,000 population from conditioning ADU permits or use on owner occupancy. Both the primary residence and the ADU may be rented to separate tenants. HOA CC&Rs in Tempe's smaller HOA communities (The Lakes, Warner Ranch, Circle G Ranches) may still impose occupancy restrictions subject to ARS 33-1817.

Surprise FAQ
Does Surprise require the owner to live on-site to have an ADU?
No, not for long-term rentals. ARS § 9-461.18 preempts municipal owner-occupancy mandates for cities over 75,000 population. The only exception is for ADUs built after September 14, 2024, that are used as short-term rentals.
Can I rent out both the main house and the ADU to different tenants in Surprise?
Yes under state law. ARS § 9-461.18 expressly permits separately leased long-term rental of the single-family dwelling and ADU on the same parcel. Sun City Grand and other HOAs may still restrict this through CC&Rs.
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.
