If two or more contiguous lots are under common ownership at any time after December 14, 1994, and one or more of these lots fails to meet the requirements of §
340-9 with regard to minimum lot area or minimum lot width, or lot building coverage, or minimum setbacks as required by the applicable sections of this chapter, or the off-street parking requirements of this chapter, such lots shall be considered to be an individual lot of land for the purpose of this chapter. Contiguous lots or parcels shall share common and abutting boundary lines and not be separated by a street or other property. Contiguous parcels under separate ownership shall be considered to make up a single lot if application is made by all owners of such parcels. No single lot shall be used in violation of the requirements of §
340-9 with regard to minimum lot area or minimum lot width, except as provided in this chapter.
