Hawkins, Jedediah, House
Why it's listed
Built around 1864 on South Jamesport Avenue in Jamesport, on Long Island's North Fork, this asymmetrical Italianate villa was commissioned by Captain Jedediah Hawkins, a ship captain and businessman. He and his brothers helped establish the menhaden oil industry, which shaped the economy of the Peconic Bay area. The wood-frame house, with brick nogging in its walls, follows a design from Samuel Sloan's 1861 pattern book Homestead Architecture. It features a tall central tower, bracketed eaves and verandas. It was the grandest house in Jamesport in its day and is the only extant building directly associated with Hawkins. Three nineteenth-century outbuildings, a summer kitchen, an outhouse and a milk house, also contribute to the property. After severe deterioration, a local builder and restoration specialist acquired the house in 2003 and restored it, guided by surviving historic fabric and photographs. It now operates as a restaurant and inn.
Significance in brief: The nomination cites Criterion B for its association with Captain Jedediah Hawkins, a wealthy businessman who helped establish the menhaden fish oil industry on eastern Long Island. Under Criterion C it is a preserved and restored Italianate country villa closely based on a design in Samuel Sloan's 1861 Homestead Architecture. It is the only surviving building directly tied to Hawkins.

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.
