Ten Broeck Mansion
Why it's listed
Ten Broeck Mansion is a two-story brick house with cellar and attic at 9 Ten Broeck Place in Albany. Built in 1797-98 on a rectangular central hall plan, it has common bond brick walls, a gabled roof with stepped gable ends, a five-bay west front and a small Greek Revival portico at the entrance. A wing extends south from the main block. Abraham Ten Broeck, who lived from 1734 to 1810, built the house while serving as Mayor of Albany. His career included the Colonial Assembly, the Continental Congress, command of county militia and service at Saratoga in 1777. After his death the house became a boys' school, and Harmanus Bleecker was among its pupils. James King bought it in the early 1830s, and Thomas Olcott purchased it in 1848. Four generations of the Olcott family lived there until they gave it to the Albany County Historical Association in 1948. It now serves as a museum with several restored period rooms.
Significance in brief: The house was built by Abraham Ten Broeck, who served as a colonial assemblyman, delegate to the Continental Congress, militia general at the Battle of Saratoga, state senator and Mayor of Albany. It is also noted for its architecture and its later use as a boys' school and as a family home for four generations of the Olcott family.

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.
