(A) Accessory structure definition.
(1) An ACCESSORY STRUCTURE is a structure that is physically detached from, and secondary and incidental in terms of use to the primary structure. An accessory structure may be larger than the primary structure; for instance, a barn (accessory structure) larger than the house (primary structure).
(2) ACCESSORY STRUCTURE does not include water storage tanks (subject to fire department needs), propane tanks, and other similar infrastructure.
Typical accessory structures are shown in the example above.
(B) Applicability. The provisions of this section apply to all structures, including but not limited to garages, carports, sheds, barns, workshops, gazebos, and covered patios which are detached from the main building on the site.
(C) Setbacks.
Type and Size of Accessory Structure | Front Setback | Side Setback | Rear Setback | Notes |
At least one of the following apply: • Contains conditioned space, or • Exceeds 12 feet in height, or • Greater than 120 square feet | 5 feet behind the street-facing façade of the main structure | 5 feet | 10 feet | |
At least one of the following apply: • Does not contain conditioned space, or • Less than 12 feet in height, or • Smaller than 120 square feet | Same as the main structure | 3 feet | 3 feet | May not be located closer to the street than the main structure |
(2) Setbacks for accessory dwelling units are addressed in § 25.08.002 of this title.
(D) Plumbing. Accessory structures may have plumbing for a washer, dryer, toilet, shower, wet bar, efficiency kitchen, and/or utility sink, except for accessory dwelling units, which shall have all plumbing required for a dwelling unit. (For standards applying to accessory dwelling units, see Chapter 25.08.)
(E) Breezeway. A breezeway may be used to combine a primary structure and an accessory structure into a single primary structure. The combined structure shall be subject to all development standards for the primary structure.
When a breezeway is constructed, the formerly separate structures (left) are now considered one structure (right). See the Glossary in Chapter 25.09 for a definition of “breezeway.”
(F) Dwellings. Except for guesthouses or accessory dwelling units, accessory buildings shall not be used for dwelling purposes. Kitchen facilities shall not be allowed in an accessory building or guesthouse, except for accessory dwelling units. See the Glossary of this zoning code for a definition of “kitchen.”
(G) Deed restriction. Where an attached or detached accessory structure is designed, arranged, or may be occupied for use as a residence or business, (i.e., contains more than one room, bath, and/or wet bar), a deed restriction must be recorded that states that the building shall not be subsequently altered or used as a dwelling unit or business without obtaining county approval.
