New York Executive Mansion
Why it's listed
Overlooking Eagle Street in Albany, the Executive Mansion is a brick house of two and one-half stories with a four-story tower, a fifteen-bay front, and a slate roof combining hip and gable forms. Thomas Olcott built it around 1860 on the former Denniston Estate, on a rise once called Gallows Hill. Originally it had mansard roofs, a cupola, large porches and a stone entrance portico guarded by two iron greyhounds. The State had earlier bought a house on Elk Street in 1838, but no governor wanted to live there. Samuel Tilden rented this house, and in 1883, under Governor Lucius Robinson, the State purchased it as the official executive mansion. In 1887 architect Issac G. Perry expanded and remodeled it, giving it details like those of Albany City Hall and the State Capitol. The work reflects the influence of Henry H. Richardson. The house has housed the state's governors for almost a century.
Significance in brief: The nomination presents the house as the long-sought official governor's residence, purchased by the State in 1883 after earlier attempts failed. Its 1887 remodeling by architect Issac G. Perry gave it details similar to Albany City Hall and the State Capitol, showing the influence of Henry H. Richardson on late 19th-century architecture.

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.
