1137.03 NONCONFORMING LOTS OF RECORD.
   Any lot of record existing at the effective date of adoption of this Zoning Code or any of its subsequent amendments which does not conform to the lot requirements of the district in which it is located is to be considered a nonconforming lot of record.
   (a)   Single Nonconforming Lots of Record .
      (1)   In any district in which single-family dwellings are permitted, a single- family dwelling and customary accessory buildings may be erected on any single lot of record at the effective date of adoption or amendment of this Zoning Code notwithstanding limitations imposed by this Zoning Code. The lot must be in separate ownership and not of continuous frontage with other lots in the same ownership. This provision shall apply even though the lot fails to meet the requirements for area or width or both, that are applicable in the district, provided that yard dimensions and requirements other than those applying to area or width, or both, of the lot shall conform to the regulations for the district in which the lot is located.
      (2)   Variances of yard requirements of this Zoning Code other than lot area or lot width shall be obtained only through action of the Board of Zoning Appeals as provided in Section 1109.02.
   (b)    Nonconforming Lots of Record in Combination. If two or more lots or a combination of lots and portions of lots with continuous frontage in single ownership are of record at the time of passage or amendment of this Zoning Code and if all or part of the lots with no buildings do not meet the requirements established for lot width and area, the land involved shall be considered to be an undivided parcel for the purpose of this Zoning Code and no portion of it shall be used or sold in a manner which diminishes compliance with lot width and area requirements established by this Zoning Code, nor shall any division of any parcel be made which creates a lot with a width or area below the requirements stated in this Zoning Code.
