Oxnard, CA Accessory Structures: ADU Rental Restrictions (2026)

12(C) sets the rules for renting an ADU or JADU once it is built. Subsection (C)(1) confirms that the ADU and/or the primary dwelling unit may be rented at all, so an ADU is not restricted to housing family members. 12(A)(2): in that situation, either the JADU or the primary dwelling unit may be rented out, so long as the owner continues to reside in whichever one is not being rented. Subsection (C)(3) then imposes the minimum-term floor that applies across the board: rental terms for ADUs and JADUs shall be longer than 30 days.

5(G) for the state-mandated ADU category created under Cal. Gov't Code Section 66323, which says the rental of any ADU or JADU created under that ministerial pathway must be for a term longer than 30 days, so the restriction is not limited to one class of unit; it applies whether the ADU went through the standard Division 13 review or the state-mandated ministerial track. In effect, the code treats any ADU or JADU rental of 30 days or less as noncompliant use of the unit, closing off vacation-rental or extended-stay-hotel style operation of a backyard unit even where the city otherwise allows short-term rental of a primary home.
