After the council and board shall have established building or set-back lines on such major highways, no new building or structure shall be erected within such building or set-back lines in the area and no permit for such building shall be issued by the city building inspector as respects the territory over which the municipality shall have enforcement jurisdiction or by the county engineer, hereby designated to administer and enforce building line and set-back regulations for the county, as respects the territory over which the county shall have enforcement jurisdiction. The city board of adjustment, as respects the territory over which the county shall have enforcement jurisdiction, shall hear appeals of any property owner aggrieved by such building line and set-back regulations in specific cases, in order than unwarranted hardship, which constitutes an unreasonable deprivation of uses as distinguished from a mere grant of privilege, may be avoided, the intended purpose of the regulations strictly observed, and the public welfare and public safety protected.
