November 12, 2025The Longest Shutdown Ever Is Over. D.C.’s ‘Bigger Problems’ Are Still Here
November 16, 2025WASHINGTON – The U.S. General Services Administration (GSA) and the U.S. National Science Foundation (NSF) today announced the execution of a lease for the new NSF headquarters. Following a publicly available request for interest from private-sector lessors, the new space located at the Randolph Building, 401 Dulany Street, Alexandria, VA, will support NSF employees in advancing the agency’s vital mission, while achieving significant cost savings for hardworking taxpayers.
“This relocation reflects President Trump’s commitment to delivering results for the American people through smart government and responsible stewardship of taxpayer resources,” said Acting Administrator Mike Rigas. “GSA reached a major milestone in consolidating our federal real estate portfolio to deliver an efficient workplace that enables both the NSF and the U.S. Department of Housing and Urban Development to better achieve their missions.”
“Virginia is a great place to be headquartered, and we are excited that the NSF will remain in Alexandria,” said Governor Glenn Youngkin. “Virginia is the proud home to many public and private-sector headquarters, and we thank GSA and NSF leadership for trusting us by keeping their national mission and the approximately 1,600 employees who work at the facility, in Virginia.”
“This relocation enables the U.S. National Science Foundation to remain in Alexandria while making responsible use of federal facilities and supporting the needs of our workforce and the research community. Co-location with the U.S. Patent and Trademark office will also strengthen both of our abilities to translate discoveries to innovation. NSF appreciates the work of the GSA, Gov. Youngkin, and everyone who has worked to ensure the agency has the infrastructure needed to meet its critical mission that supports our economic and national security,” said Brian Stone, performing the duties of NSF director.
The selected facility offers proximity to a number of public transit options, including the King Street and Eisenhower Metro stations, Amtrak and the Virginia Railway Express.
GSA will continue to work with NSF to ensure a smooth transition, enable effective design and build-out of the space, and support NSF’s full mission in this new location. We also look forward to welcoming HUD into their new home in the near future.
