(a) Survey real property under its control (i.e., property reported on its financial statements) at least annually to identify property that is not utilized, underutilized, or not being put to optimum use. When other needs for the property are identified or recognized, the agency must determine whether continuation of the current use or another use would better serve the public interest, considering both the Federal agency's needs and the property's location. In conducting annual reviews of their property holdings, the GSA Customer Guide to Real Property Disposal can provide guidelines for Executive agencies to consider in identifying unneeded Federal real property;

(b) Maintain its inventory of real property at the absolute minimum consistent with economical and efficient conduct of the affairs of the agency; and

(c) Promptly report to GSA real property that it has determined to be excess.
