ACCESSORY DWELLING UNITS (“Attached” ADUs/ ”Detached” DADUs) involve upgrading existing structures, adding capacity, and converting underutilized spaces into functional living areas. This can include adding kitchenettes, installing bathrooms, transforming garages, basements, or outbuildings into livable spaces, or creating a complete freestanding residence for either in-home care, extended family, long-term stays, or rental income.
