The city recognizes that accessory dwelling units (ADUs) in primarily residential zones can be an important tool in the overall housing plan for the city. The purposes of the ADU standards of this code are to:
A. Allow opportunities for property owners to provide social or personal support for family members where independent living is desirable;
B. Provide for affordable housing opportunities;
C. Make housing units available to moderate income people who might otherwise have difficulty finding homes within the city;
D. Provide opportunities for additional income to offset rising housing costs;
E. Develop housing units in single-family neighborhoods that are appropriate for people at a variety of stages in their life cycle; and
F. Preserve the character of single-family neighborhoods by providing standards governing development of ADUs. (Ord. 21-25: Ord. 09-23 § 2)
ATTACHED ACCESSORY DWELLING UNIT (AADU): A self-contained dwelling unit within an owner occupied single-family residence or located on an owner occupied property that is incorporated within the single-family residence which maintains complete independent living facilities for one or more persons, including permanent provisions for living, sleeping, eating, cooking and sanitation including a separate kitchen and/or laundry facilities.
DETACHED ACCESSORY DWELLING UNIT (DADU): A self-contained dwelling unit separated from a single-family residence but located on an owner occupied property which maintains complete independent living facilities for one or more persons, including permanent provisions for living, sleeping, eating, cooking and sanitation including a separate kitchen and/or laundry facilities.
OWNER OCCUPANCY: When a property owner, as reflected in title records, makes his or her legal residence at the site as evidenced by voter registration, vehicle registration, driver's license, county assessor records or similar means. (Ord. 21-25: Ord. 09-23 § 2)

(Ord. 21-25: Ord. 09-23 § 2)
