ADU Owner Occupancy
Redding requires the property owner to live on-site if the lot has a junior accessory dwelling unit, but not if the lot has only a standard accessory dwelling unit. Municipal Code Section 18.43.140(I)(3) draws this owner-occupancy line, tying the requirement to the JADU's shared-entry, shared-utility design rather than to standalone ADUs.
