It was documented by the Historic American Buildings Survey (HABS) in 1937. The house was added to the National Register of Historic Places on January 1, 1976, for its significance in agriculture and architecture. It was designated a contributing property of the Washington Valley Historic District on November 12, 1992.

John Smith was born in Caldwell, New Jersey. In 1798, he purchased 140 acres (57 ha) of land here. He was a member of the Presyterian Church in Morristown and a trustee of the Washington Valley Schoolhouse. The house has two sections. The oldest is a one and one-half frame structure dated as 18th century. It was moved and attached to the main section in 1812. The main section is a two-story red brick building constructed in 1812, with the year set in black brick on the west gable. After Smith's death in 1855, the property was inherited by his son, Jonathan Hugh Smith. He improved the productivity of the farm by adding limestone and built a lime kiln on the property. He was a member of the South Street Presbyterian Church and also a trustee of the schoolhouse.
