The United States General Services Administration (GSA) is a federal agency responsible for promoting effective use of federal real property assets, as well as the disposal of real property that is no longer mission-critical to federal agencies. With thousands of properties in the federal portfolio, disposing of underused federal property is a considerable task. GSA—while working together with partner federal agencies, state and local governments, non-profit organizations, business groups, and citizens—leaves a lasting positive impact on communities by making valuable government real estate available for numerous public purposes.
