An accessory use shall be secondary to a primary use and shall be allowed only in conjunction with a principal use or building to which it relates under the same regulations as the main use in any zoning district. Accessory uses and structures are also subject to the development and site regulations found in Chapter 300, General Site Regulations. Accessory structures shall be designed to be of similar/compatible architecture and materials as the main buildings, and in addition shall be located, developed, and operated in compliance with the following standards in the agricultural and residential zone districts as follows:
A. Agricultural Accessory Structures. In the AC and RR districts, agricultural accessory uses and structures are allowed subject to the provisions of this section. Agricultural accessory uses and structures include any uses that are customarily related to an agricultural use including stables, barns, pens and sheds or other structures for the housing of such animals, feed, equipment, and tools.
1. Size. The maximum lot coverage allowed by the development standards shall not be exceeded.
2. Height. The agricultural accessory structure shall not exceed thirty-five (35) feet in height unless approved by the Zoning Administrator.
3. Building Separation. Agricultural accessory structures shall be separated from any main building by a minimum of six (6) feet.
4. Setbacks. Agricultural accessory structures shall meet all setback requirements of the main building.
B. Residential Accessory Structures. Residential accessory structures include any uses that are customarily related to a residence, including garages, greenhouses, storage sheds, studios, workshops, detached covered decks (i.e. a patio structure), detached uncovered decks and patios two and one-half (2.5) feet in height or greater, and similar structures. Uncovered decks under two and one-half (2.5) feet in height, and fences are not subject to the regulations in this section. Additional regulations for residential second units are located in Section 301.16, Second Dwelling Units.
1. Attached Structures. An attached structure is not, by definition, an accessory structure. A structure shall be considered attached to a main structure if it is architecturally compatible with and made structurally a part of the main structure, including sharing a common wall or roof-line with the main structure. A structure attached with a breezeway connecting a door of the residence to a door of the detached structure, with a roof that is a minimum of eight (8) feet in width and fifteen (15) feet in length, will be considered a part of the main structure for purposes of this Ordinance. An attached structure shall comply with all requirements of this Ordinance applicable to the main structure, including, but not limited to setback requirements and height limits.
2. Number of Structures. The number of detached accessory structures shall be limited to two (2) unless approved by the Zoning Administrator.
3. Size. The floor area of detached accessory structures shall not exceed a cumulative floor area of one thousand two-hundred (1,200) square feet unless approved by the Zoning Administrator. In reviewing a request for additional size, the Zoning Administrator may consider neighborhood compatibility, overall lot coverage, relationship of the accessory structure to the main structure and use, and any circumstances unique to the neighborhood. In no case shall the accessory building exceed the ground floor area of the main building and in no case shall the maximum lot coverage allowed by the development standards be exceeded.
4. Height. The maximum height shall not exceed eighteen (18) feet. The Zoning Administrator may consider buildings exceeding eighteen (18) feet in height that are stepped back one (1) foot from the required side and rear setback lines for every foot of height above eighteen (18) feet up to twenty-four (24) feet.
5. Building Separation. Detached accessory structures requiring a building permit, with the exception of shade structures, shall be separated from any main building by a minimum of six (6) feet.
6. Setbacks. When located in the rear one-third of a lot, detached accessory buildings shall not be located closer than four (4) feet to any rear property line. In instances where the rear property line is coterminous with an alley right-of-way, the accessory building shall not be closer than one (1) foot to such rear property line. Detached accessory buildings shall meet all other setback requirements of the main building. (Ord. 1866, 11-19-2019)
