Every building or structure or section or portion thereof moved over, upon, along, or across any street shall be moved under the inspection and supervision of the Board. The Board shall appoint an inspector for the moving of any building or structure and of each section or portion thereof; provided that in case two or more buildings or structures, or two or more sections or portions thereof are being moved at the same time along a route or routes so situated that one person can inspect the same, only one person shall be appointed therefor. Such inspection and supervision in each case shall be for such time as the Board shall deem necessary for the performance of such service. (Amended by Ord. No. 136,358, Eff. 5/6/68.)
