54 U.S.C. § 306121 — Lease or exchange

(a) Authority To Lease or Exchange. No matter what other laws say, each federal agency, after consulting the Council, (1) must, as much as is practical, find and use alternatives — including adapting the property for new uses — for historic property the agency doesn't need for its current or planned work, and (2) may lease historic property it owns to any person or organization, or trade any property it owns for comparable historic property, if the agency head decides the lease or trade will properly preserve the historic property. (b) Proceeds of Lease. No matter what other laws say, the agency that signs the lease may keep the lease money and use it to cover administration, maintenance, repair, and related costs for that property or for other National Register property the agency owns or controls. Any leftover money must be deposited in the Treasury by the end of the second fiscal year after the year it was received.
