An accessory dwelling unit is an attached or detached residential dwelling unit that may provide complete independent living facilities for 1 or more persons, and which may include provisions for living, sleeping, eating, cooking, and sanitation on the same parcel where the primary single-family dwelling is situated. An accessory dwelling unit may also be known as a secondary dwelling unit, granny flat, property caretaker's dwelling or guest house.

(b) Property caretakers, however, working as ranch hands for approved commercial horse boarding facilities may use a motor home, travel trailer or 5th wheel RV unit for their accommodation. See Vol. II, § 1-6-7(D)(7).
