After the war, it was painted white to cover up the soot, and became known as the White House.ADDED: While the original answer is technically correct, I believe the questioner is asking about more recent history. President Harry S. Truman had to move out of the White House when it was discovered that the floors and foundation of the building were deteriorated and crumbling from age. During the White House renovation he lived across Pennsylavania Avenue from the White House in the "Blair House."
