Accessory Dwelling Units. Except for a sale pursuant to subsection H of this section, and except for junior accessory dwelling units pursuant to subsection (G)(2) of this section, no owner of the subject lot shall be required to occupy either the primary residence or accessory dwelling unit as the owner's residence.
2. Junior Accessory Dwelling Units. Owner-occupancy shall be required in the single-family residence in which the junior accessory dwelling unit will be permitted. The owner may reside in either the remaining portion of the structure or the newly created junior accessory dwelling unit. Owner-occupancy shall not be required if the owner is a governmental agency, land trust, or housing organization.
H. Sales to Qualified Buyers. An accessory dwelling unit may be sold or conveyed separately from the primary dwelling to a qualified buyer if all of the criteria in subsections (H)(1) through (H)(5) of this section are met. For the purposes of this subsection, the term "qualified buyer" means persons or families of low or moderate income, as that term is defined in Health and Safety Code Section 50093.

Full Breakdown
Municipal Code § 11.43.040(G) splits owner-occupancy by unit type. For a standard accessory dwelling unit, no owner of the lot is required to occupy either the primary residence or the ADU. For a junior accessory dwelling unit, the smaller, in-home unit capped at 500 square feet, owner-occupancy of the single-family residence is required, though the owner may live in either the main house or the new junior unit. That requirement is waived only if the owner is a government agency, land trust, or housing organization.
Violations & Fines
Renting out both the primary residence and a junior ADU with no owner living on-site violates § 11.43.040(G)(2) and can result in denial or revocation of the junior ADU permit.
