A. Where a district boundary line divides a lot which was in single ownership of record at the time of enactment of the ordinance, the rules applying to the less restricted portion of such lot shall be considered as extending to the entire lot. If the more restricted portion of such lot is more than 50 feet beyond said dividing district boundary line, such less restricted use shall be limited to the portion of the lot lying within 50 feet of said boundary line.
B. Questions concerning the interpretation of exact location of district boundary lines shall be determined by the Board of Adjustment according to rules and regulations which it may adopt, as hereinafter provided under Chapter 167.
