Accessory dwelling units (ADUs) are by nature in keeping with residential areas’ character and give residents the ability to adjust their living environment according to their needs by moving into the ADU as they age and downsize. ADUs can face permitting hurdles through appeals, though, and that can be eliminated by exempting them from local permitting. Communities could exempt ADUs that meet all setback and dimensional requirements, which still makes sure that these aspects are regulated, and limit such exemptions to owner-occupied lots (that way the owner can live in the ADU or primary structure).
