ADU Rules
Ventura permits ADUs and JADUs on lots with existing or proposed single-family or multifamily dwellings, consistent with California Government Code § 65852.2 (ADU) and § 65852.22 (JADU). State law preempts local bans in single-family zones, and Ventura's local zoning standards in Division 13 of the San Buenaventura Municipal Code (SBMC) must conform to those statewide floors.

Few RestrictionsADU Rental Restrictions
ADUs in Ventura may be rented, but state law prohibits rental terms shorter than 30 days. Gov. Code § 65852.2(a)(6) bars cities from approving ADUs as short-term rentals of 30 days or less; this preempts use of an ADU for Airbnb-style stays.
