The Cannon House Office Building (Cannon Building)--completed in 1908--and the East and West House Underground Garages (East and West Garages)--built in 1968--have deteriorated over time and will need to be repaired, according to assessments conducted for the Architect of the Capitol (AOC). AOC plans to renovate these three facilities over approximately the next 8 years as part of a long-term effort to reduce maintenance backlogs and execute major renewal projects to sustain all Capitol Complex facilities.
