Section 2302 of the Thomas R. Carper Water Resources Development Act of 2024, also known as the USE IT Act, mandates public reporting of occupancy and utilization rates of public buildings and federally-leased space. The data below presents key utilization statistics for each executive department covered by the Chief Financial Officers Act of 1990, also known as CFO Act agencies. The data represents occupancy over the period from Jan. 12, 2026, through March 6, 2026 in accordance with the definition of occupancy in the statute. CFO Act agencies are the definitive source for this data, submitting it to OMB Collect. Each agency determines the data submitted and any excluded assets.
An agency head may exempt individual public buildings from utilization monitoring and publication if determining that such monitoring or publishing would be detrimental to national security.
For questions about CFO Act agencies’ data, please contact the agency. For questions about the USE IT Act, visit USE IT Act and occupancy data or contact useitquestions@gsa.gov.
