Landon, Samuel, House
Also known as: Thomas Moore House

Why it's listed
Built around 1750 by Samuel Landon, this L-shaped, one and one-half story house on Main Road in Southold is an example of New England Colonial building on eastern Long Island. It has a central fireplace, shingled walls and roof, a five-bay front with an entablature-style door surround, and a kitchen wing added about 1860. The site was granted in the seventeenth century to shipwright Thomas Moore, whose original house disappeared, possibly by fire, which is why the building is also known by his name. Later owners included a blacksmith and War of 1812 officer, members of the Corwin family, and a local postmaster. It served briefly as a caretaker's house in the late 1930s. The Southold Historical Society bought it in 1970, removed later additions such as a dormer and Greek Revival entrance, and now uses it as a museum with exhibits and school programs. It was listed for its role in Southold's settlement and for its intact colonial architecture.
Significance in brief: The house is significant under Criterion A for the settlement and growth of Southold, because the site was granted to shipwright Thomas Moore in the seventeenth century. It is significant under Criterion C as a highly intact example of New England Colonial residential architecture, with rooms grouped around a large central fireplace.

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.
