Approximate location: the National Park Service places this pin arbitrarily within the property, not at a surveyed point (stated accuracy ±12 m).
Why it's listed
Built in 1854 for John C. Ostrom, this two-story brick house at 151 Main Street in Brockport, New York, is a fine example of the Italianate style. It has a five-bay facade, a low hipped roof topped by a wooden cupola, a full-width porch with chamfered piers and brackets, and a stepped series of rear wings. The interior keeps its center hall, fourteen-foot ceilings, Ionic-columned wooden arches, carved marble mantels, and oak and cherry woodwork. A brick Gothic Revival-inspired carriage house also survives on the 1.1 acre lot. The property is also tied to Dayton S. Morgan, who bought it in 1867 and lived there until he died in 1890. Morgan's firm built improved McCormick reapers in Brockport, and his company grew into a national business with offices in Chicago and Jackson, Michigan. Today the house serves as a house museum.
Significance in brief: The house is a distinguished local example of Italianate residential architecture, with a hipped roof, cupola, full front porch and a highly intact interior. It is also associated with Dayton S. Morgan, a Brockport industrialist who manufactured McCormick reapers there and lived in the house from 1867 until his death in 1890.

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.
