Why it's listed

Built in 1749 in what is now the Village of Fort Johnson, this two-story limestone house served as the home of Sir William Johnson, a Mohawk Valley land agent, trader and military leader. It is the second and oldest surviving of his residences. For more than a decade it was the scene of treaty-making and annual meetings with the Iroquois, along with visits from leaders of tribes in New England and the Mid-West. Johnson's diplomacy helped keep the Iroquois allied with the British during the French and Indian War. The building is also valued as a Georgian house of the frontier: five bays wide, with a center hall plan, random ashlar limestone walls, a slate hipped roof with dormers, and a symmetrical south facade with a central entrance porch. It is described as one of the best preserved buildings of its type in New York State. Johnson's son John lived here after 1763, before moving to Johnson Hall in 1774.

Significance in brief: It is the second and oldest surviving residence of Sir William Johnson, where he held annual meetings and major congresses with the Iroquois and other tribes. His diplomacy there kept the Iroquois allied with the British during the French and Indian War. Architecturally, it is a well-preserved example of a mid-18th-century Georgian detached house on the colonial frontier.

What listing means for this property

National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved.
