Federal Real Property: Further Consolidating DOT Office Space Could Save Hundreds of Millions of Dollars

What GAO Found The Department of Transportation (DOT) and its component agencies are underutilizing their office space department-wide based on the Utilizing Space Efficiently and Improving Technologies (USE IT) Act benchmark of 60 percent utilization. Specifically, GAO found that 89 percent of DOT’s 189 office buildings, including the DOT and the Federal Aviation Administration (FAA) headquarters complexes, were underutilized in August and September 2025 based on the USE IT benchmark. This was largely consistent with DOT’s USE IT Act reporting in March 2026.
