Yavapai County, AZ Accessory Structures: ADU Owner Occupancy (2026)

Section 537(B)(7)(d) ties owner-occupancy directly to the certificate date, not to the ADU's age or design. It applies whenever 'the owner of the property where an ADU is used as a vacation or short-term rental must reside on the property if a Certificate of Occupancy or similar final approval for the ADU was issued by the County on or after September 14, 2024.' An ADU that received its Certificate of Occupancy before that date, and is used as a vacation or short-term rental, isn't reached by this residency condition; the county drew the line at ADUs approved on or after the date the current Section 537 standards took effect.

The rule sits alongside two other Section 537(B)(7) conditions that apply to the same short-term-rental scenario: the ADU still can't be used for nonresidential purposes such as Special Events requiring a permit under Resolution No. 1752 (subsection (c)), and renting the property out, long-term or short-term, doesn't excuse the owner from the separate A.R.S. §33-1902 rental-registration filing with the County Assessor (subsection (b)). Read together, an owner who wants to run a newer ADU as a short-term rental has to actually live on the parcel, keep the use residential, and stay current on the state rental registration; all three conditions apply at once, not as alternatives.
