Dorr, Dr. Joseph P., House
Why it's listed
This brick house on Route 23 in Hillsdale, Columbia County, is a well-preserved example of early 19th century Federal-style domestic architecture. It has an upright main block with a recessed story-and-a-half kitchen ell, built together in a single episode. Walls are load-bearing red brick on a rubble stone foundation, with cut-stone lintels and sills, twelve-over-twelve windows, and a pedimented gable with a leaded elliptical fanlight. Inside are a side hall and double parlors, five wood mantels, six-panel doors, plaster walls, and a kitchen hearth with a bake oven. Changes have been limited, though parquet floors and a Greek Revival-style door surround were added later. The house was associated with Dr. Joseph P. Dorr, whose family was prominent in Columbia County in the 19th century. It was built as Hillsdale grew from activity along the Columbia Turnpike, and it remains a single-family dwelling with a modified carriage barn on the grounds.
Significance in brief: The nomination presents the house as a substantially intact, relatively unaltered example of early 19th century Federal-style domestic architecture in the region. It also has ties to Dr. Joseph Priestly Dorr and the Dorr family, who were prominent in Columbia County affairs, and to the growth of Hillsdale along the Columbia Turnpike.

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.
