ADU Owner Occupancy

Anaheim cannot require owner occupancy on standard ADUs permitted after January 1, 2020 because California Government Code §65852.2(a)(6), made permanent by AB 976 (2023), prohibits local owner-occupancy mandates. Junior ADUs (JADUs) under AMC 18.38.110 still require owner occupancy of either the primary dwelling or the JADU because they share walls and utilities.
