It is tied to Lewis Kemp, an early Mad River Township settler who also donated land for the township's oldest burial ground. It is also a surviving example of a vernacular saltbox with an early brick addition.","narrative":"Built around 1806, this two-story saltbox on Burkhardt Avenue in Dayton began as a three-bay rough-cut limestone house with a coursed stone foundation. A two-bay brick addition later extended it while keeping the saltbox form, and a small gable-roofed front porch was added around 1900. Lewis Kemp and his wife Elizabeth, with eight children, came from Frederick County, Maryland, with a party of 96 people and settled in Mad River Township, where he built the house soon after arriving. Kemp also donated about an acre in 1815 for the township's oldest burial ground, and a log schoolhouse was built nearby the same year. The house is regarded as the oldest private residence in Dayton. When nominated, it was vandalized inside but structurally sound, and a public housing project was being built behind it. Its location on a hazardous curve raised the possibility of demolition for road straightening.","period_of_significance":"19th Century (specific date c. 1806 for the stone portion)","architect_builder":null,"architectural_style":"Vernacular Saltbox","criteria":[],"status_note":"Described as deteriorated and vandalized, with doors, hardware and one mantel removed and wiring exposed, but structurally sound with excellent potential for restoration.
