If, at that time of passage of this subchapter, a lot, or the aggregate of contiguous lots held in a single ownership, has an area or dimension which does not meet the lot size requirements of the zone in which the property is located, the lot or aggregate holdings may be occupied by a use permitted outright in the zone subject to the other requirements of the zone and providing, if there is an area deficiency, residential use shall be limited to a single-family residence.
