Setbacks, Accessory Structures, and Building Height Measurements


  1. Front yard: no accessory structure shall be placed in the front yard of any lot.
  2. Rear yard:
    1. adjacent to an alley: 10 feet;
    2. not adjacent to an alley: 2.5 feet.

  6. Detached accessory structures: detached accessory structures are allowed in a side and rear yards provided that:
    1. The projected roof area of the structure does not exceed one hundred twenty (120) square feet.
    2. The maximum height of the structure at the highest point if the roof is 8 feet (8') or less;
    3. The structure is not placed on a permanent aggregate foundation; and
    4. No part of an accessory structure shall be placed in the front of the setback established by the location of the principal structure.

  4. Fifty (50) percent of lot must remain unobstructed open space.


Building Height Measurements

HEIGHT OF BUILDING: The height of a building is the vertical distance from the highest point of the structure to the average of two points: 1) the highest finished grade adjoining the building and 2) the lowest finished grade adjoining the building (excluding window wells and similar below-grade features). The calculated building height shall exclude any portions of the structure eligible for exemption under the provisions of this title. For purposes of calculating the height of a building, the finished grade shall not be artificially manipulated to gain more than six inches (6") in overall height.
