Carman, Cornelius, House

The pin is a point inside the NPS boundary polygon, not a surveyed location.
Why it's listed
Built around 1835 on River Road South in the hamlet of Chelsea, this one-and-one-half story clapboard house sits on a raised stone basement and has a five-bay west facade with a central entrance, sidelights and transom, and a Doric portico. Pairs of brick chimneys and tripartite windows flanked by quarter-round lights mark the gable ends, and the roofline mixes a Federal cornice with a Greek Revival frieze. A shed-roofed rear extension, borrowed from New England practice, and a center-passage plan set it apart from similar local houses. Later wings were added on the sides and rear. The house was built for Cornelius Carman, a Hudson River boat builder who operated a shipyard in Chelsea. He built sloops, barges and steamers, including the river's first steam ferry in 1828, and is credited with introducing the movable centerboard on Hudson sloops. The house is valued as a late example of a regional Dutch-influenced farmhouse type and as a reminder of Carman's maritime career.
Significance in brief: The house is presented as an outstanding, late example of a vernacular farmhouse type that developed in western Dutchess County in the Federal period, blending Dutch and English tastes and showing the shift from Federal to Greek Revival style. It is also significant for its link to Cornelius Carman, a Hudson River boat builder who built the river's first steam ferry in 1828 and is credited with introducing the movable centerboard on Hudson sloops.

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.
