§ 155.093  MEASUREMENTS, COMPUTATIONS, AND EXCEPTIONS.
   (A)   Setbacks and yards.
      (1)   Measurements. Setbacks refer to the unobstructed, unoccupied open area between the furthermost projection of a structure and the property line of the lot on which the structure is located. Setbacks shall not contain any structure except when in conformance with this code. (See division (A)(4) (Architectural Projections) of this section.)
      (2)   Yards required for buildings. A yard or other open space required for a building shall not be included as part of a yard or other open space for another building.
      (3)   Front yard modifications. In existing residential areas, the required minimum front yard setback shall be the average of the existing front yard setback of all principal structures on the same side of the street and within 300 feet of the subject lot. If the average is less than the district requirement, the required minimum front setback is the average as calculated. This does not apply to panhandle lots. Modification of the front yard in accordance with this section will not create a nonconforming lot unless the lot or structure does not meet other applicable provisions of this code.
      (4)   Architectural projections.
         (a)   Cornices, eaves, sills, canopies, or similar architectural projections may extend or project into required side yards not more than two inches for each one foot of width of such side yard, and may extend or project into a required front or rear yard not more than 30 inches.
         (b)   Bay windows and chimneys may project into a required front, side, or rear yard not more than 18 inches, provided that the side yard is not reduced to less than three feet.
         (c)   Open structures, such as porches, balconies, platforms, carports, and covered patios, shall be considered a part of the building to which they are attached and shall not project into the required minimum front, side, or rear yard.
         (d)   Ramps, elevators, escalators, and similar improvements or devices constructed or installed to provide access by persons with disabilities may extend or project into a required front, side, or rear yard to the extent necessary to conform the accessibility device to design and materials specifications set forth in regulatory standards promulgated under the authority of the Americans with Disabilities Act.
   (B)   Height exceptions. Chimneys, towers, penthouses, scenery lofts, monuments, cupolas, domes, spires, false mansards, parapet walls, similar structures, and necessary mechanical appurtenances are exempt from the height regulations.
   (C)   Interior lot.
      (1)   The required minimum front yard setback shall be measured from the front lot line or the street right-of-way.
      (2)   The lot line located directly behind the rear of the structure, as determined by the Safety and Service Director, shall be the rear lot line and the rear yard setback shall be applied.
      (3)   All other lot lines shall be considered the side lot lines and the side yard setback shall be applied.
   (D)   Corner lots.
      (1)   Lots having a frontage on more than one street shall have the required front yard setback along each street.
      (2)   On any corner lot no fence or planting shall be erected or maintained within 20 feet of the corner right-of-way that interferes with traffic visibility across a corner. See corner visibility triangle § 155.107(J) (Visibility).
   (E)   Double frontage lots.
      (1)   Where a lot is considered a double frontage lot, the required minimum front yard setback shall be provided from both streets.
      (2)   The remaining lot lines shall be considered side lot lines and the side yard setback shall be applied to those lot lines.
   (F)   Cul-de-sac or curved-street lot.
      (1)   For a cul-de-sac lot or a lot abutting a curved street, the front yard setback shall follow the curve of the front property line.
      (2)   Lots on a cul-de-sac shall be required to have a minimum lot width of 40 feet measured at the right-of-way line.
      (3)   On a cul-de-sac or curved roadway, the required 40-foot street frontage is to be measured at the street right-of-way on the curve of the cul-de-sac or curved roadway.
