State Department overseas building management (Bureau of Overseas Buildings Operations)

State's building backlog jumped from $96M to $3B in a single year

Summary

Two GAO reports, 21 months apart, examine different parts of the same system: the State Department's Bureau of Overseas Buildings Operations, which owns or leases about 8,500 properties worth tens of billions of dollars across roughly 290 diplomatic posts. A September 2021 report found State's deferred-maintenance backlog leapt from $96 million to $3 billion in a single year -- a jump from a change in accounting method, not new damage -- with a quarter of its buildings in poor condition and no plan to fix it. A June 2023 report found the program built to assess hurricane, earthquake, and flood risk to that same portfolio has fewer than half the staff a State-commissioned workforce analysis says it needs.

State's Bureau of Overseas Buildings Operations (OBO) manages more than 8,500 owned and leased properties supporting about 290 diplomatic posts worldwide. A September 2021 GAO report found State's deferred-maintenance backlog jumped from $96 million in fiscal 2019 to $3 billion in fiscal 2020 -- almost entirely because OBO changed how it estimates the backlog, not because buildings suddenly deteriorated. More than a quarter of State-owned buildings were in poor condition, and OBO had no plan specifying the funding or time frame needed to fix them; officials estimated it would take 30 to 40 years at then-current funding. A June 2023 GAO report examined a different piece of the same portfolio: the Climate Security and Resilience (CS&R) program, created in 2020 to assess hurricane, earthquake, and flood risk to State's roughly $70 billion in overseas facilities, was staffed at 4.33 full-time positions against a contractor workforce analysis recommending 11.

A backlog that grew on paper, not on the ground

Between fiscal 2015 and 2019, State's overseas property portfolio grew 11 percent by count and square footage, and operating expenditures grew 24 percent, from $530 million to $656 million a year. Maintenance funding didn't keep pace: it averaged $505 million annually over that period, essentially flat. Then, in its fiscal 2020 financial report, State's reported deferred-maintenance backlog jumped from $96 million to $3 billion. traced the jump to a methodology change -- OBO began supplementing manual condition surveys with parametric models that estimate how much building systems have deteriorated based on age and expected lifespan, rather than relying on facility managers to report complete survey data. The new number is a more complete estimate of a problem that was already there, not evidence the problem got 31 times worse in a year.

The bigger number came with a real design choice attached. To calculate it, OBO applied a single acceptable-condition standard -- a 70-percent condition index, rated "fair" -- to every asset type: chancery office buildings and communications infrastructure held to the same bar as recreation centers and warehouses. OBO had considered a tiered standard, weighting mission-critical buildings against a higher bar (85 percent) than non-mission-dependent ones (70 percent), and didn't adopt it. 's own analysis found 2,197 of 8,293 State-owned buildings and structures, more than a quarter, in poor condition -- and among assets State itself designates mission-critical, like the Manila chancery that houses nearly 200 staff, the rate was one in five.

found State followed five of nine leading practices for managing a deferred-maintenance backlog, partially followed three, and skipped one entirely: developing a plan that specifies the funding and time frame needed to bring the backlog down. Without it, officials could only estimate -- 30 to 40 years at current funding levels -- rather than show Congress a path. made five recommendations, covering the condition standard, mission-criticality weighting, standardized inspections, a funding-and-timeline plan, and predictive investment modeling. State agreed to all five.

The risk-assessment program running on four people

The 2023 report picks up a different thread in the same portfolio: what happens when embassies get hit by the hazards the maintenance backlog leaves them less prepared for. State's Havana embassy is still repairing hurricane damage from 2017 -- an $18 million fix, delayed further by the difficulty of importing construction materials into Cuba, not expected to finish until 2024. In Manila, recurring flooding has pushed OBO toward a preliminary plan to replace the entire post, including the only U.S. Veterans Affairs medical clinic located outside the United States -- a project says could exceed $1 billion.

OBO's answer to these risks is the Climate Security and Resilience program, created in 2020 with no dedicated funding line of its own -- its budget grew from $5.6 million to $9.2 million between fiscal 2020 and 2022 only by pulling $21 million from three other OBO accounts. Staffing tells the same story. A contractor workforce analysis commissioned by OBO recommended growing the program from 4.33 to 11 full-time positions -- hazard specialists, data analysts, an integration lead -- to keep up with rising demand for its work across the department. Instead of adding those positions, State's fiscal 2024 budget request directed 11 new hires to OBO's separate Energy Program; officials told they hadn't yet decided whether CS&R would get any of the staff its own plan says it needs. Faced with the shortfall, CS&R rewrote its own implementation timeline in April 2022 -- stretching from 6 years to 12, through 2033 -- and even that revised plan assumes the program won't be fully operational at current staffing.

What each report recommended

's 2021 recommendations targeted how State counts and prioritizes its maintenance backlog; State agreed with all five, though it pushed back on the implication that OBO lacked any plan at all. 's 2023 recommendation was narrower: once fiscal 2024 staffing decisions were final, CS&R should revisit its own goals and timelines to match whatever staff it actually received, rather than keep running on a plan built for positions that don't exist. State concurred with that recommendation too.

The takeaway

  • A $3 billion number that says more about accounting than damage. State's deferred-maintenance backlog for its overseas buildings grew 31-fold in a single year, from $96 million to $3 billion, because OBO adopted a more complete estimating method -- not because a quarter of the portfolio fell apart in twelve months. That quarter was already in poor condition; the new method just measured it.
  • The mission-critical label doesn't buy better upkeep. Chancery offices and other buildings State itself calls essential to its mission were in poor condition at nearly the same rate (20%) as buildings it calls non-essential (28%) -- because State applies one condition standard to both, a choice found it had considered changing and didn't.
  • The office meant to assess disaster risk to $70 billion in facilities is running at under 40% of its own recommended staffing. With 4.33 of a recommended 11 full-time positions and no dedicated budget line, the Climate Security and Resilience program has already had to push its own implementation plan back six years, to 2033.
