A nonconforming lot may be used and a building may be constructed upon a nonconforming lot, notwithstanding its deficiency in area or dimension, provided that any building, structure or use thereon shall comply with all applicable regulations as to use, location, setback, coverage, dimension and condition, as well as to all performance standards and common regulations, except to the extent that the zoning hearing board, on application made for special exception, finds that conformity to such location or dimension or common regulation would deprive the applicant of all reasonable use of the lot. It shall be incumbent upon the applicant to conform as nearly as possible to each, all and every locational and dimensional standard and each and every common regulation and performance standard, notwithstanding the status as nonconforming lot of record, except to the extent that the requirement would deprive the applicant of all reasonable use of the lot.
