Where a district boundary line established in this subchapter or as shown on the Zoning Map divides a lot which was in single ownership at the time of enactment of this chapter, the use authorized thereon and the other district requirements applying to the least restricted portion of such lot under this chapter shall be considered as extending to the entire lot, provided the more restricted portion of such lot is entirely within 25 feet of the dividing district boundary line. The use so extended shall be deemed to be conforming.
