Sag Harbor Village District (Boundary Increase)
Why it's listed
Sag Harbor's historic district covers the older core of a port village on Long Island's South Fork. It enlarges a district first listed in 1973, adding about 35 percent more land after a 1990-91 village survey. The district contains nearly 900 resources, mostly freestanding wood-frame houses one to three stories high, built from the late eighteenth to the mid-twentieth century, along with commercial blocks on Main Street, four cemeteries and two large parks. Lots were first laid out in 1745 south of the Long Wharf, and the 'Y'-shaped road pattern survives. Development followed whaling in the early nineteenth century, factory work such as the Fahys watchcase factory, and later resort building, including Queen Anne cottages on Palmer Terrace. The district also includes Eastville, a nineteenth century African American and Native American community. Boundaries exclude areas dominated by post-World War II construction or heavy alteration.
Significance in brief: The district preserves a village whose street pattern dates to 1745 and whose housing stock spans the late eighteenth to mid-twentieth centuries, from the whaling era through factory and resort development. It also includes Eastville, described as a unique nineteenth century African American and Native American community. The expansion was based on a 1990-91 survey that identified many more eligible buildings.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
