10-2-5: ZONING LOT REQUIREMENTS:
   A.   Contiguous Lots: When two (2) or more contiguous lots of record or parts of lots of record, one or both of which are substandard with respect to lot width and/or area for the regulations of the district in which they are located are in the same ownership or control as defined in this title and are in combination of such a size as to constitute at least one conforming zoning lot, such lots of record or portions thereof shall, for purposes of this title, be regarded as one zoning lot. Any development of that resulting zoning lot must be in conformity with all the regulations of the district in which it is located. If the resulting zoning lot exceeds the minimum requirements of the district in which it is located, the zoning lot may be subdivided into additional zoning lots so long as each resulting zoning lot meets or exceeds the minimum requirements of the district in which it is located. Such contiguous substandard lots of record in such common ownership or control on the effective date of this title shall be considered as being one or more conforming zoning lots for purposes of this title whether or not such common ownership or control ceases to exist.
   B.   Division Or Sale Of Improved Lots: No zoning lot improved with a dwelling unit or other principal building or structure shall thereafter be divided into two (2) or more lots, and no portion of any zoning lot which is improved with a dwelling unit or other principal building or structure shall be sold unless all zoning lots resulting from each division or sale and improved with a dwelling unit or other principal building or structure conform to all of the bulk regulations of the zoning district in which they are located.
   C.   Reduction In Dimensions: No yard or zoning lot shall be reduced in dimension or area so that the lot width, lot frontage, lot area, yards, or required open space become less than the minimum requirements set forth herein. Yards, zoning lots, parcels, or subdivision lots of record created after the effective date of this title shall meet at least the minimum requirements set forth herein. (Ord. 2010-04-07, 4-1-2010)
