Hammond House
Why it's listed
Built around 1719 by William Hammond, this small frame farmhouse in Eastview, near Hawthorne, was a tenant dwelling on the Philipsburg Manor. Hammond reportedly built it without a basement so it could be moved if his lease ended. The house has a five-bay front porch, a central section with two later wings: a detached cottage moved and joined to it in 1835 as a kitchen wing, and an east wing added in 1860. Inside are wide-board floors, large fireplaces and 18th-century paneling in the parlor. It is believed to be one of only two surviving Philipsburg tenant houses, from about two hundred that once stood on the manor. Hammond's son James, who inherited the farm, commanded the First Regiment of Westchester Militia in the Revolution and was held prisoner by the British for eighteen months. The family kept the property for several generations. The county historical society repaired it in 1926 and now opens it to visitors.
Significance in brief: The nomination argues it is an early 18th-century farmhouse and one of only two surviving Philipsburg Manor tenant dwellings, out of about two hundred originally. It was also the homestead of the locally prominent Hammond family, including James Hammond, a Revolutionary War militia colonel. It offers insight into the county's 18th-century vernacular architecture.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
