(A) In any case where a lot of official record or a lot which has received final plat approval by the Planning Commission, at the date of the adoption or amendment of this chapter, does not conform to the width, depth, or area requirements of this chapter with respect to such lots, it shall be considered a legal nonconforming lot.
(B) Any such lot which has received preliminary plat approval by the Planning Commission shall be reviewed by the Planning Commission and may be considered a legal nonconforming lot if it is found that such lot may reasonably be used as a building site for any structure or use permitted within the zoning district involved without requiring a dimensional variance.
(C) Any subdivision or tract of land which has been previously rezoned to a residential classification may be developed in accordance with the lot area requirements for said zoning district rather than the area requirements contained in this chapter, provided that all requirements of the subdivision regulations are observed.
