Carll House (Boundary Decrease)
Why it's listed
Dating to about 1750, this farmhouse at 380 Deer Park Road in Dix Hills is a two-and-one-half story, five-bay residence with a gable roof, a center hall plan, a massive central chimney and shingle sheathing. A one-and-one-half story side wing has a saltbox profile, and the interior keeps its period finishes and a beehive oven. A Federal period door surround with sidelights reflects an early nineteenth century remodeling. The property also holds a mid-nineteenth century cottage and three early nineteenth century barns arranged around a small pond, set behind dense vegetation and hedges. The house is considered important as an intact example of early settlement architecture in Huntington, and its size reflects the prosperity of the Carll family, who occupied it through the nineteenth century. It was the birthplace of Major Timothy Carll, a Revolutionary War soldier. Together with its outbuildings, it survives as a rare, relatively unaltered farm complex amid extensive development.
Significance in brief: The house is argued to be an intact, representative example of early settlement period architecture in Huntington. Its large size reflects the prosperity of the locally prominent Carll family. It survives with four period outbuildings as a rare historic farm complex amid heavy development, and it was the birthplace of Revolutionary War soldier Major Timothy Carll.

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.
