      2. Chain-link and woven mesh fences are prohibited in street and corner yards, except that chain-link fences, including those that are anodized or vinyl-clad, constructed without slats, are permitted in the street and corner yard area on corner lots when the side of any principal structure located on the subject lot faces a street, provided that the fence does not exceed four feet (4') in height and is located only in the area from the rear line of the structure to the rear lot line.
      3. Fences up to six feet (6') in height are permitted in the street and corner yard area on corner lots when the side of any principal structure located on the subject lot faces a street if the rear of the structure faces the rear of a structure that is located on an adjacent corner lot, provided that the fence is located only in the area from the rear line of the structure to the rear lot line.
      4. Fences up to six feet (6') in height are permitted in the street and corner yard area of an R-zoned lot occupied by a principal nonresidential use if the lot has multiple street frontages and contains a parking lot without a structure. Such fence must be an open-design fence (See DGMC Section 28.10.010(a)(5)) and be constructed along the parking lot perimeter immediately adjacent to an arterial street or non-residentially zoned property.

On double-frontage lots, when the rear of any principal structure located on the lot faces a street, and all directly abutting lots share this layout, the yard along that street frontage is considered a rear yard for purposes of these fence regulations. On double-frontage lots, when the rear of any principal structure located on the lot faces a street, and one or more directly abutting lots has the front of a principal structure that faces the same street, the fence must adhere to the yard requirements of the front facing principal structure.
