To require congressional approval before the sale, disposal, declaration of excess or surplus, transfer, or conveyance of Federal property with historical significance, and for other purposes.

HR 2046 requires federal agencies and the President to obtain congressional approval before selling, transferring, or disposing of any U.S. property listed on the National Register of Historic Places. Specifically, officials must first notify Congress and then secure a joint resolution approving the action. This applies to all historically significant properties, including land, buildings, monuments, and sites owned by the federal government. The bill directly affects federal agencies and the executive branch by adding a legislative review step for all such transactions.
