1153.02 EXISTING LOTS OF RECORD.
   In any district where dwellings are permitted, a one-family detached dwelling may be erected on any lot, fifty feet or wider, of official record as of the effective date of this Zoning Ordinance, irrespective of its area or width, provided the owner of such lot does not own any adjoining property, and provided further:
   (a)    Each of the side yard widths of any such lot shall not be less than ten percent of the width of the lot; provided, however, that on a corner lot, the width of the side yard adjoining the side street lot line shall not be less than eight feet or twenty percent of the frontage, whichever is the greater.
   (b)    The depth of the rear yard of any such lot need not exceed twenty percent of the depth of the lot, but in no case shall it be less than twenty feet.
   (c)    Where three or more contiguous unimproved lots of record with less than the required area and width are held by one owner, the Planning Commission may require replatting to fewer lots to permit compliance with minimum yard requirements. (Ord. 40-63. Passed 12-12-63.)
