The Army needs $34 billion to renovate and modernize its buildings, with $19 billion required to clear the maintenance backlog alone. Fort Bragg, North Carolina, and U.S. Army Garrison Hawaii require a significant amount of work, accounting for $11.2 billion of the total costs. The Congressional Budget Office report does not mention recent problems with moldy barracks, but it states that two-thirds of Army buildings do not require renovation or modernization. However, Fort Bragg and Hawaii facilities have higher deferred maintenance costs due to the larger share of the Army's building inventory and the need for significant upgrades or redesigns. Completing all deferred maintenance would cost $19 billion, while the Army has only spent an average of $2.5 billion annually on maintenance and sustainment.
