Frequently Asked Questions
Can I build an ADU on my Phoenix property?
Yes. Arizona HB 2297 (effective September 2024) requires Phoenix to allow ADUs on single-family lots and removed the previous owner-occupancy requirement. Phoenix updated its local ordinance to comply. ADUs can be up to 50% of your primary dwelling floor area or 1,200 sqft (whichever is less). No additional parking is required. Side and rear setbacks cannot exceed 5 feet per state law.
What are the short-term rental rules in Phoenix?
Phoenix requires STR registration ($250/year). Arizona SB 1350 (2016) originally preempted cities from banning STRs outright, but SB 1168 (2022) gave cities back some regulatory authority including the ability to require registration, impose safety requirements, and penalize nuisance properties. Maximum occupancy is 2 guests per bedroom plus 2 additional guests. A local contact person must be designated.
Does Phoenix have a solar mandate?
No, Phoenix does not have a solar mandate for new construction. However, Arizona's strong HOA solar protection law (ARS 33-1816) means your HOA cannot prohibit solar installations. Phoenix receives approximately 299 sunny days per year, making it one of the best solar markets in the US. Building permits are required for all solar installations.
