Summary
Parker flatly bars renting or leasing an accessory dwelling to third parties. An owner also cannot live in the accessory unit and rent out the primary residence instead; the accessory dwelling can only house occupants tied to the primary household.
(4) General conditions for accessory dwellings.
(a) No accessory dwelling, either attached or detached, may be rented or leased to third parties by the owners or residents of the primary residence. The owners of the primary residence may not live in the accessory dwelling, and rent to third parties the primary residence.
Full Breakdown
37(O)(4)(a) states that no accessory dwelling, either attached or detached, may be rented or leased to third parties by the owners or residents of the primary residence, and it closes the obvious workaround: owners of the primary residence may not live in the accessory dwelling and rent the primary residence to third parties instead. 37(O)(2)(d) that must be renewed annually. An attached dwelling needs at least one acre, must be architecturally integrated with the primary residence, and cannot sit more than 20 feet from the rear or side of the main dwelling.
Because the special use permit is annual, the city has a recurring checkpoint to confirm a unit is not being used as a rental. The no-rental rule protects the underlying zoning purpose, keeping the property as a single-family use rather than a de facto duplex or short-term rental operation.
Violations & Fines
Renting or leasing an accessory dwelling to a third party, or swapping residents between the primary house and accessory unit to enable a rental, violates § 156.37(O)(4)(a) and is enforceable under § 156.99(B) as a misdemeanor carrying a fine of up to $2,000 per offense, with each day of the violation a separate offense; the required annual special use permit renewal also gives the city grounds to deny continuation.
