The Hammond House is located on Grasslands Road (New York State Route 100C) in the Eastview section of the town of Mount Pleasant, New York, United States. It is a wooden building whose oldest part dates to the 1720s, with latter additions during the 19th century. In 1980 it was added to the National Register of Historic Places.It is one of the oldest houses in Westchester County, and one of only two remaining tenant houses from the Philipsburg Manor. It also has a rich Revolutionary War history. Col. James Hammond, son of the original owner, commanded the Patriot Westchester Militia. Some historical evidence supports a legend that George Washington visited the house for a brief conference with Hammond in 1780, leaving just before the house was surrounded by Loyalists.During the war the Hammond family bought the land; they held on to it until the 1920s, when New York City acquired the property to protect its watershed. It was planning to demolish the structure, when the county historical society bought the deteriorating house and restored it for use as a historic house museum. It remained open in that capacity for another half-century. When the society shifted its focus to primarily serving as an archive, it sold it to New York Medical College, which used as a medical research laboratory for a decade. It was again saved from potential demolition by two brothers who bought it in the 1990s. They have been restoring it.
