No service station shall have an entrance or exit for vehicles within 200 feet along the same side of a street of any school, playground, church, hospital, public building or institution, except where such property is in another block or abuts another street which the lot in question does not abut.

No service station shall be permitted where any oil draining pit or visible appliance for any purpose (other than gasoline filling pumps or air pumps) is located within 50 feet of any future street line or within 150 feet of any residential district. All such appliances or pits, other than gasoline filling pumps, or air pumps, shall be within a building. Gasoline and air pumps shall be permitted within the required front yard space of service stations, but shall be no closer than 20 feet to any future street line.

No junked motor vehicle or part thereof, or motor vehicles incapable of normal operation upon the highways shall be permitted on the premises of any service station. It shall be deemed prima facie evidence of violation of this chapter if more than three motor vehicles incapable of operation are located at any one time upon any premises not within a closed and roofed building excepting, that a number not exceeding six motor vehicles may be located upon any service station premises outside of a closed or roofed building, for a period of time not to exceed 48 hours and providing that the motor vehicles are awaiting repair by the owners thereof.
