The current narrowest house in the United States is also a spite house. It's a small house in Old Town, Alexandria, Virginia, a historic suburb of the DC metro area. It fills the carriageway between two houses and was built to keep people's wagons out of that carriageway. It predates the NY house by 50 years.
