(A) The owner of a lot of official record, which lot at the time of the adoption of this chapter does not include sufficient land to conform to the yard or other requirements of this chapter, may submit an application to the Board of Zoning Adjustment for a variance from the terms of this chapter in accordance with the provisions of §§ 155.120 through 155.124. The lot may be used as a building site, provided, however, that the yard and other requirements of the district are complied with as closely as is possible in the opinion of the Board of Zoning Adjustment.
(B) If two or more adjoining and vacant lots with continuous frontage are in a single ownership at any time after the adoption of this chapter and the lots individually are too small to meet the yard, width and area requirements of the district in which they are located, the group of lots shall be considered as a single lot or several lots of minimum permitted size, and the lot or lots in one ownership shall be subject to the requirements of this chapter.
