The Church Administration Building (CAB) is an administrative office building in Salt Lake City, Utah, serving as the headquarters of The Church of Jesus Christ of Latter-day Saints (LDS Church), the fourth-largest Christian denomination in the United States. Completed in 1917, the building is adjacent to Temple Square, between the Joseph Smith Memorial Building and the Lion House, on South Temple Drive. It differs from the Church Office Building in that it is much smaller and furnishes offices for the First Presidency and the Quorum of the Twelve Apostles. It also houses offices for other general authorities and their personal staff.
