Yes, whenever GSA determines that it is more advantageous to assign property temporarily rather than permanently, it may do so. If the space is for office, storage, or related facilities, GSA will determine the length of the assignment/reassignment. Agencies are required to reimburse the landholding agency (or GSA, if GSA has become responsible for seeking an appropriation for protection and maintenance expenses) (see § 102-75.970) for protection and maintenance expenses. GSA may also temporarily assign/reassign excess real property for uses other than storage, office or related facilities. In such cases, the agency receiving the temporary assignment may be required to pay a rental or users charge based upon the fair market value of the property, as determined by GSA. If the property will be required by the agency for a period of more than 1 year, it may be transferred on a conditional basis, with an understanding that the property will be reported excess at an agreed upon time (see § 102-75.85). The requesting agency is responsible for protection and maintenance expenses.
