It is an agency of the legislative branch of the federal government and is accountable to the United States Congress and the Supreme Court. Both the agency and the head of the agency are called "Architect of the Capitol". The head of the agency is appointed to a 10-year term by the President of the United States, confirmed by the United States Senate, and is accountable to the President.

The head of the agency sits on the Capitol Police Board, which has jurisdiction over the United States Capitol Police, and on the United States Capitol Guide Board, which has jurisdiction over the United States Capitol Guide Service. Until 1989, the architect of the Capitol was appointed by the president of the United States for an indefinite term. Legislation in 1989 provides that the president appoints the architect for a term of ten years, with the advice and consent of the Senate, from a list of three candidates recommended by a congressional commission. On confirmation by the Senate, the architect becomes an official of the legislative branch as an officer and agent of Congress. The architect is eligible for reappointment after completion of the term.
