The Dupont Underground and Anacostia Boathouse Lease Extension Authority Act of 2026 authorizes the Mayor of the District of Columbia to extend the leases for two District-owned properties: the Dupont Underground and the Anacostia Boathouse. Specifically, the bill allows for the extension of the lease for the Dupont Underground, which is approximately 75,000 square feet of subterranean space, from its current expiration date of November 18, 2029, to November 18, 2042. Similarly, the lease for the Anacostia Boathouse, located at 1900 M Street, S.E., will be extended from June 7, 2030, to June 7, 2047.

This legislation overrides previous laws regarding the sale of real estate in the District that are no longer required for public purposes, thereby granting the Mayor the authority to amend the existing leases with DCenter Inc. and The Anacostia Community Boathouse Association, Inc. The bill includes a fiscal impact statement adopted from the committee report and outlines the effective date contingent upon the Mayor's approval and a 30-day Congressional review period.
