Summary
Campbell County's A-1 Agriculture Zone allows one accessory dwelling unit per farm lot under § 154.076(C)(19), capped at 1,000 square feet on a minimum five-acre parcel, but the same subsection bars the ADU from being 'held out to the public or used as a short or long-term rental.' The identical rental ban applies to ADUs approved in the R-RE Rural Estate Zone under § 154.077(C)(12)(h).
(19) Accessory dwelling unit (ADU) with the following conditions: (a) The lot shall consist of a minimum of five contiguous acres with a primary dwelling unit; (b) The ADU shall be limited to one unit and subordinate in area, extent, and purpose, to the primary dwelling unit; (c) The total living space of the ADU shall not exceed 1,000 square feet; (d) The primary dwelling unit and the ADU must share the same driveway encroachment; (e) Sufficient off-street parking must be provided for uses on the lot. A paved parking pad must be provided for the ADU; (f) The driveway apron must be paved for a minimum of 12 feet; (g) The unit may not be used for a home-based business; and (h) The unit may not be held out to the public or used as a short or long-term rental.

Full Breakdown
Campbell County permits accessory dwelling units only as a conditional use in two rural residential zones, and both versions of the ordinance attach the same rental prohibition. 076(C)(19) requires the host lot to have at least five contiguous acres with a primary dwelling, limits the ADU to one unit that is 'subordinate in area, extent, and purpose' to the main house, caps total living space at 1,000 square feet, requires the ADU to share the primary home's driveway encroachment with a paved apron at least 12 feet wide, and bars the unit from housing a home-based business.
077(E)(3). 049 before the county will issue a building or occupancy permit, and sufficient off-street parking, including a paved parking pad, must be provided for the unit. The rental ban means the ADU may only be occupied by the property owner's family, farm employees, or other non-paying occupants; converting it into a listed short-term rental or a leased long-term rental unit removes it from the conditions under which the Board of Adjustments approved it.
Violations & Fines
Renting out an ADU short-term or long-term, or listing it publicly for rent, breaches the conditional-use approval granted under § 154.076(C)(19)(h) or § 154.077(C)(12)(h). Under § 154.999, that is a class B misdemeanor, with each day of the prohibited rental counted as a separate offense, and the Board of Adjustments can revoke the conditional use approval.
