The Oil House is a small, brick masonry structure with a metal hip roof and metal door built in 1895. The structure sits on a concrete floor slab; it measures nine feet by seven feet and was built to hold 360 gallons of oil. The exterior walls are white with a red door and roof. The interior has cream-colored walls and a white ceiling. It was constructed as part of a system-wide conversion that began in 1888 and was completed about 1918 when stations converted from lard oil to the brighter burning, but more volatile kerosene, necessitating fuel storage segregated from housing.
