Military Building Deferred Maintenance as a Continuing Defense Readiness and Budget Signal
The condition of military buildings remains an important federal infrastructure issue, not because a new flagship report has displaced prior analysis, but because subsequent oversight and budget materials confirm that deferred maintenance continues to carry operational and fiscal significance. The Congressional Budget Office’s August 2024 report, The Deferred Maintenance Backlog for the Military Services’ Buildings, estimated that the Air Force, Army, Marine Corps, and Navy together faced roughly $50 billion in deferred maintenance for more than 100,000 buildings maintained by their active components in the United States and its territories. That estimate was based on data current as of September 2020, yet the report remains an important benchmark for understanding the scale of the problem. (Congressional Budget Office)
What makes the issue especially important is that deferred maintenance is not simply an accounting matter. Military buildings support command functions, training, administration, housing, storage, and other mission-enabling activities. When maintenance is postponed, deterioration compounds over time, functional reliability declines, and later repairs often become more expensive. CBO’s framework helps make that relationship visible by using the Facility Condition Index, which compares the estimated cost of deferred maintenance to a building’s replacement value. In that analysis, the Army and Navy carried the largest shares of the total backlog, while the Marine Corps and Navy showed particularly high deferred maintenance costs on a per-building and per-square-foot basis.

Subsequent federal oversight has reinforced the view that building condition should be treated as a live governance issue. In 2025, GAO added building condition as a high-risk topic within federal real property, citing large increases in the cost of addressing deferred maintenance. GAO reported that the cost of addressing Department of Defense and civilian federal building repair backlogs more than doubled, rising from $171 billion to $370 billion from fiscal year 2017 through 2024. GAO also warned that unless the trend is reversed, federal assets will continue to deteriorate and may require premature replacement at significantly higher cost than timely maintenance and repair would have required. That broader federal context matters because it suggests that deferred maintenance is now being viewed not merely as a localized facilities challenge, but as a structural public management problem.

Current defense budget materials point in the same direction. The Department of Defense’s FY 2026 Operation and Maintenance budget documents continue to include substantial Facilities Sustainment, Restoration, and Modernization funding, including roughly $5.59 billion in the Air Force O&M account. The FY 2026 budget materials also reflect continued FSRM funding across the military departments, indicating that sustainment and restoration pressures remain active components of annual defense resource allocation rather than historical artifacts. Even where precise backlog figures are not restated, the persistence of these appropriations lines demonstrates that the maintenance burden remains embedded in current planning and execution.

For federal contractors, advisors, and policymakers, the practical significance is straightforward. Building maintenance backlogs are often early indicators of future demand for sustainment services, repairs, recapitalization planning, and modernization support. They also shape installation resilience, force quality of life, and the long-term affordability of military infrastructure. The most prudent reading of the available materials is therefore not that deferred maintenance was a one-time 2024 concern, but that it remains an unresolved defense infrastructure issue with continuing budgetary and operational consequences.
