Some military barracks ‘chronically neglected’ due to $285 billion in maintenance backlogs, GAO finds

The Department of Defense does not request enough funding to fully meet its installation maintenance and major improvement needs, a Government Accountability Office report found.

The department sought to fund 90% of its maintenance needs, but the GAO found that the services continue to request funding for only about 80% of their needs, according to the report released Friday. The funding shortfall led to an estimated $285 billion of maintenance backlogs in fiscal 2025.

“DOD has not fully determined the risks to its mission and to the quality of life of its personnel as a result of not meeting its funding goal,” the report reads. “Fully determining and communicating these risks would provide better information to DOD and Congress to weigh budget priorities.”

GAO authors examined Army, Navy, Marine Corps and Air Force military installations across the U.S. and its territories for this report.

The report found that the department does not request the full amount of maintenance funding as recommended by its Facilities Sustainment Model, which estimates the average annual sustainment funding requirement for facilities based on their size, location and other factors.

This contributed to the increased backlog of deferred maintenance needs. Even though in 2014 an Under Secretary of Defense for Acquisition, Technology, and Logistics memorandum was issued to establish a goal of funding regular maintenance at 90% or higher of the amount estimated by the Facilities Sustainment Model, the GAO continues to find that the services are not meeting that goal.

Instead, the Army, Navy and Air Force requested about 80% for fiscal years 2017 through 2020. The Marine Corps requested funding decreased from 80% to 40% over the past five fiscal years, opting to fund more facility restoration and modernization projects in exchange for reduced sustainment funding, the report says.

Maintenance and improvement projects’ backlogs can contribute to service members’ quality of life and negatively affect installations’ missions.

“By requesting less funding for installation maintenance and improvement projects than its models and experts recommend, DOD has chosen to accept some degree of risk that mission or quality of life will be negatively affected,” the report says.

In past reports, the GAO has found that barracks maintenance were “chronically neglected” and resulted in poor conditions of enlisted service members that affected their quality of life. Thousands of service members lived in substandard barracks, with some hosting potentially serious health and safety risks, a 2023 report found.

Of the 31 recommendations issued in 2023, the department implemented 19 as of April 2026. But many remain unaddressed, such as establishing an oversight structure for barracks, the report says.

The GAO found that challenges in hiring and retaining key maintenance workers are seen in remote and isolated locations and other obstacles include private sector employment competition as well as federal hiring, pay and work eligibility practices.

Military departments have not fully identified the extent of maintenance workforce shortages or created plans to address the hurdles.

The GAO also found that installations rely on maintenance work order data systems to respond to needs, but the tracking is limited and the data is generally unreliable for determining the effectiveness of maintenance performed across the services.

In the report, the GAO made 13 recommendations, including strengthening departmental oversight, determining risks associated with funding maintenance below levels proposed and improving maintenance data reliability.

The department fully or partially concurred with 12 recommendations and did not concur with one.
