A. Setbacks--Corner Lots. The setback from the street upon which the principal building will face shall be the minimum required front yard. The setback from the street upon which the side of the building will face shall be the minimum required front yard setback for the street upon which it is contiguous.

B. Setbacks--Through or Double Frontage Lots. Front yard setbacks for double frontage lots shall be provided for both streets upon which the lot has frontage, and any accessory use(s) shall be prohibited from the required front yard setback of the street upon which the principal building fronts.

C. Setbacks--Partially Developed Areas. Where the majority of lots in a block fronting on the same side of a street between two intersecting streets are lawfully occupied with buildings having greater or lesser front yard depth than required by these regulations, no building hereafter erected or altered shall vary in the front yard setback by more than five feet from the average depth of said existing front yard setbacks without written approval of contiguous property owners. However, in no case shall setbacks be less than fifteen (15) feet.

D. Setbacks--Multiple Buildings on Lot. Whenever more than one main building is to be located on a lot, the required yards shall be maintained around the group of buildings and buildings shall be separated by a horizontal distance that is at least equal to the height of the highest adjacent building.
