Stony Kill Farm

Why it's listed
Stony Kill Farm is a farm complex on Route 9D in Fishkill, about four miles north of Beacon. Its main building is a five-bay, two-and-a-half story stuccoed manor house completed in 1843, with a neoclassical form and restrained Gothic Revival details, including pointed-arch gable windows and carved marble mantels in each of its eight principal rooms. Nearby stands the Washington House, an eighteenth-century stone tenant dwelling built in four sections, along with a nineteenth-century board and batten barn complex, early twentieth century residences, and later farm buildings. The land descends from a 1683 purchase by Gulian Verplanck, and the Verplanck family lived at the manor house until 1943, when it was given to New York State on condition that it remain an active farm. The property was valued for its family associations, its intact mid-nineteenth century house, its tenant house, and its surviving farmland in a developing area. It now serves as an agricultural and environmental education center.
Significance in brief: The nomination cites the complex's ties to the Verplanck family, a leading Hudson Valley family, and to the manorial land system. It notes the largely intact mid-nineteenth century manor house in its original setting, and the Washington House as a rare, little-altered eighteenth-century stone tenant house. It is also described as one of the last active farms in a developing area.

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.
