(a) In any residence district where forty percent (40%) of the property fronting upon the side of a street between two intersecting streets and located in such district has been improved with buildings as of August 8, 1978, and a front yard of greater depth that the minimum or of less depth than the minimum required by the schedule of height and area regulations has been provided for the majority of such buildings, such minimum may be disregarded; but no building hereafter erected or altered in such residence district between the existing buildings and the street corner shall be placed nearer to the street than the minimum prescribed in this chapter or the average distance already established by the buildings already erected, whichever is greater; but the minimum depth of front yard for a dwelling on a lot between two adjoining lots, on each of which a building exists as of August 8, 1978, shall be the average of the depths of front yards observed by such buildings.
Where less than forty percent (40%) of such property has been improved with buildings, or where dwellings do not front upon a street, the minimum depth of front yard shall be as required by the schedule of height and area regulations.
(b) For a corner lot in the "A" or "B" residence district, the minimum depth of yard along either frontage shall be the depth of rear which is required along the same street for the adjoining lot; provided, that nothing in this provision shall be interpreted as to reduce the buildable width of a corner lot of record as of August 8, 1978, to less than twenty-five feet; or to require more than one yard adjacent to the street line in excess of twenty-five feet in depth (or width); or in a retail business district to require a yard along either frontage to be more than fifteen feet in depth (or width).
(c) When a dwelling in a light industrial district fronts on an alley, the front line of such dwelling shall be at least fifteen feet from the center of such alley.
(d) In a retail business district located within a use district where front yards are required, the depth of front yard need not exceed that required by this chapter for buildings in an adjoining residence district and located in the same block and fronting on the same street.
(e) In the "B" residence district, where all the lots fronting on one side of a street between two intersecting streets are within a retail business district and at least twenty percent of such lots are improved with commercial buildings as of August 8, 1978, a front yard greater in depth than the average distance already established by such existing commercial buildings shall not be required.
(f) In the "B" residence district, where part of the lots fronting on one side of a street between two intersecting streets are within a retail business district and part within a residence district, a front yard provided for a lot in such retail business district need not exceed the least depth already established by an existing building which fronts on the same street as the lot in question and is located between such lot and the adjacent residence district in the same block.
