After Roosevelt's death, his son Elliott Roosevelt lived there for a while. He made some renovations, such as adding dormer windows and a mud room. Later he sold the house to the Potter family, who gave their name to the street leading to the home. It remained in their possession until 1996, when it was sold again to the Open Space Institute (OSI). The following year it was recognized as a National Historic Landmark, and the OSI began renovations, removing Elliott Roosevelt's additions and thinning some of the trees that had obstructed the view. In 2001, it was turned over to the National Park Service to be made part of the existing historic site. The house was opened to the public for the first time in 2001. It is used as a conference center, in addition to being open to the public.
