(A) Where the owner of a lot of official record in any residential district at the time of the adoption of this chapter or his successor in title thereto does not own sufficient contiguous land to enable him to conform to the minimum lot size requirements of this chapter, such a lot may be used as a residential building site, provided, however, that the requirements of the district are complied with or a variance is obtained from the Board of Adjustment.
(B) Notwithstanding the foregoing, whenever two or more adjoining vacant lots of record are in single ownership at any time after the adoption of this chapter and such lots individually have less area or width than the minimum requirements of the district in which such lots are located, such lots shall be considered as a single lot or several lots which meet the minimum requirements of this chapter for the district in which such lots are located.
