   (B)   Setback yard exceptions. Setback yards provide space for private yards and building separation for fire protection/security, building maintenance, sunlight and air circulation. The setback standards are also intended to allow for flexibility in maintaining existing structures and in developing attached housing, consistent with the policies of the city’s comprehensive plan. Setbacks may be adjusted through the following means.

      (1)   Minor encroachments into a setback yard for chimneys, porches, decks, eaves and similar parts of a structure are permitted, pursuant to applicable building codes.

      (2)   The Planning Commission may reduce the required front yard setback requirement for a new or expanded building where it finds that one or more buildings on lots abutting the subject site and on the same block face (street frontage) have less than the minimum front yard setback. In such cases, the Commission may establish a minimum setback that is equal to the average front setback on the two abutting lots. Where only one building is on an abutting lot on the same block face, the Commission shall find the average using the standard setback and the setback of the existing building. The above exception does not apply to garage openings, carport entries and structures where vehicles are serviced, stored or repaired; the minimum street setback of 20 feet shall be maintained for those structures.

      (3)   All other setback yard exceptions are subject to review and approval of a variance pursuant to §§ 153.310 through 153.314.
