The Congressional Budget Office is located on the fourth floor of the Ford House Office Building, Second and D Streets, SW, Washington, DC 20515-6925. The building is just across Third Street from the Federal Center SW Metrorail station, but the entrance is on Second Street, on the other side of the building. Street and garage parking are limited, and neither is provided by CBO. Many visitors find it easiest to arrive via Metrorail. The Orange, Blue, and Silver lines serve the Federal Center SW station.
