Prescott Valley FAQ
Can I build an ADU in Prescott Valley, AZ?
Yes in many zones, but the rules are set by the Prescott Valley Land Development Code, not by Arizona's statewide ADU mandate. With a population under 75,000, Prescott Valley is not preempted by A.R.S. §9-461.18 (HB 2720), so the Town's own zoning controls where ADUs are allowed and under what conditions.
Does Arizona's statewide ADU law apply to Prescott Valley?
No. Arizona House Bill 2720 (codified at A.R.S. §9-461.18) only mandates by-right ADUs in cities and towns of 75,000 or more residents. Prescott Valley has approximately 49,856 residents and is exempt — local zoning still controls.
Do I need septic approval for a Prescott Valley ADU?
Yes if your parcel is not on Town sewer. Yavapai County Environmental Health must review your existing septic system's capacity (or approve a new system) before the Town issues the building permit. Many lots outside the Town core rely on septic.
Sedona FAQ
Can I rent my ADU on Airbnb?
Only if the ADU received its certificate of occupancy before September 14, 2024, OR if the property's primary dwelling is the owner's primary residence.
Can I sell the ADU separately?
No — ADU ownership must remain with the principal dwelling owner.
