Tweddle Farmstead
Why it's listed
This farmstead on Beaver Dam Road in Montgomery, New York, centers on a farmhouse built in stages during the early nineteenth century. A small rear wing, said to be the original dwelling, was joined about 1830 by a five-bay, one-and-a-half story main block built by George Van Alst. The front doorway with sidelights, transom and corner blocks, the square porch columns, cut stone foundation, parlor mantels and molded plaster cornice all reflect Greek Revival taste, and much of the interior fabric and original hardware survives. The property also includes a late nineteenth-century stone springhouse, a wagonhouse, a barn built in 1935 after fire destroyed earlier barns, buried workshop ruins and five old maples on the front lawn. Thomas Tweddle bought the farm in 1868 for his son John, and the family has kept it since. The farmstead was listed for its architecture and for what it can show about local farming practices.
Significance in brief: The farmhouse is argued to be an intact example of Greek Revival detailing, both inside and out. The surrounding farm outbuildings and landscape features add to its value. Together they reflect the town's growth as a prosperous rural farming community and may yield information on agricultural practices of the Wallkill and lower Hudson Valley.

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.
