Requires the Securities and Exchange Commission to stop signing new leases for general‑purpose office space itself and instead use the General Services Administration (GSA) to lease that space. Current SEC leases are not changed or canceled.

Directs the Government Accountability Office (GAO) to update its 2016 review of Federal entities with independent leasing authority and report to three Congressional committees on which entities still hold such authority, any changes since 2016, how much space they lease, whether they used GSA, and progress on past GAO recommendations.
