Blanket Parking Waiver: Unlike state law which allows cities to require parking unless specific exemptions apply (e.g., near transit), Dixon waives parking for all ADUs and JADUs. Sale to Qualified Buyer: The ordinance allows separate sale/conveyance of an ADU to a qualified buyer (typically low-income/non-profit) per Gov Code 66341.
