A fence, wall, or hedge up to six feet may be located anywhere on a parcel except in a traffic safety sight area, a required front setback, or a street-side setback - where the maximum is 42 inches. When ground levels differ between adjoining parcels, the height of a property-line fence is measured from the finished grade of the highest contiguous parcel.
