The minimum lot, yard and height requirements herein set forth shall prevail in all cases, except as follows:
(a) Existing Nonconforming Lots. A single-family dwelling may be constructed as a permitted use in any R District on a nonconforming lot if the following conditions are satisfied:
(1) At the time of this Zoning Ordinance such lot is in existence as a separate entity.
(2) At the time of this Zoning Ordinance the owner of such lot does not own an adjoining lot.
(3) The plan for the lot and for the proposed single-family dwelling shall be in at least seventy percent (70%) compliance with each of the following requirements for single-family dwellings as specified in the district in which the lot is located: lot area, lot width, rear yard, side yard and maximum building coverage.
(b) Height Limitations. Height limitations need not apply to church spires, cupolas and domes, monuments, water towers, chimneys, smokestacks, silos, flag poles, radio and television towers, masts and aerials and parapet walls extending not more than four feet above the limiting height of the building.
(c) Front Yard Exceptions. Where forty percent (40%) of the lots of a block is occupied by buildings, the average setback of such buildings determines the dimensions of the front yard in the block, but the maximum front yard need not exceed thirty-five (35) feet from the lot line. Provided however, that in the event an unimproved lot is situated between two improved lots, each having a principal building within twenty feet of the side lot line of an unimproved lot, the front yard may be reduced to a depth equal to that of the greater front yard of the two adjoining lots, provided, however that it may not be reduced to below ten (10) feet.
