The White House is owned by the federal government of the United States, which means it is not privately owned by an individual or organization. Instead, it serves as the official residence and workplace for the President of the United States.
The building itself is part of the public domain and is managed by the National Park Service. While the President lives there during their term in office, they do not own the property personally. It has been the residence of every U.S. president since John Adams in 1800 and is often seen as a symbol of the U.S. government.
In summary, while a sitting president resides in the White House, it is owned by the government and remains a historical and cultural landmark accessible to the public through tours and various events.
