Accessory Buildings & Structures

 ACCESSORY BUILDINGS

Accessory buildings are subordinate to, and serve a purpose customarily incidental to, the principal building.  Examples of Accessory Buildings include sheds, detached garages, and gazebos. A site plan indicating the intended location of the building is required with the permit packet. Requirements for accessory buildings are:

  • Accessory buildings may not be constructed over easements or impact drainage.
  • Required setbacks must be maintained. Typically, a 5 ft. setback from the property line is required. Contact Community Development to verify property specific setbacks.
  • Typically, accessory buildings may only be located in rear yards. If you have a corner lot, contact Community Development to discuss locations.
  • 10 feet minimum separation is required between the principal building and the accessory building.
  • The maximum height of accessory buildings is 12 feet, measured to the midpoint of the roof peak. 
  • Construction materials should be similar to the principal structure and in character with the surrounding built environment.
  • All accessory buildings and structures cannot cover more than 30% of the rear yard.
  • Protection from decay is required on all wood siding, sheathing, and framing less than 8 inches from the exposed ground
  • Building Slabs: 
    • Buildings 400 sq. ft. or less may use a 4" slab.
    • Buildings 401 to 600 sq. ft. must have a 12" x 12" reinforced edge footing completely around the perimeter below the 4" slab; vegetation shall be stripped and a minimum 4" compacted aggregate shall go under the floor.
    • Buildings 601 sq. ft. or larger shall have 42" deep frost footings.
  • Restrictive covenants may have additional requirements.
ACCESSORY STRUCTURES
Accessory structures are similar to accessory buildings in that they are subordinate and incidental to the principal building, but accessory structures are not enclosed and do not have a roof. Fences, decks, pools, dog runs, flagpoles, and sport courts are a few examples of accessory structures. A site plan indicating the intended location of the structure must be provided with the permit application. Requirements for accessory structures are:

  • Accessory structures, except decks over 50 sq. ft. and fences, may be constructed in any yard, but all accessory buildings and structures cannot cover more than 30% of that yard.
  • Accessory structures cannot interfere with easements or drainage.
  • Required setbacks must be maintained. Typically, a 5 ft. setback from the rear property line and a 2 ft. setback from the side property line is required. Contact Community Development to verify property specific setbacks.
  • There are additional requirements for the following accessory structures. Click the links for an information and permit packet, or Contact Community Development for those projects without a link.
  • Restrictive covenants may have additional requirements.
