GSA is responsible for two acquisition regulations:

Federal Acquisition Regulation (FAR):   The FAR was established to codify uniform policies for acquisition of supplies and services by executive agencies. It is issued and maintained jointly, pursuant to the Office of Federal Procurement Policy (OFPP) Reauthorization Act, under the statutory authorities granted to the Secretary of Defense, Administrator of General Services and the Administrator, National Aeronautics and Space Administration. Statutory authorities to issue and revise the FAR have been delegated to the Procurement Executives in Department of Defense (DOD), GSA and National Aeronautics and Space Administration (NASA).

GSA Acquisition Regulation (GSAM) along with Acquisition Letters:  The GSAM incorporates the General Services Administration Acquisition Regulation (GSAR) as well as internal agency acquisition policy.  The rules that require publication fall into two major categories:

                (1)   Those that affect GSA’s business partners (e.g., prospective offerors, contractors).

                (2)   Those that apply to acquisition of leasehold interests in real property.  The Federal Acquisition Regulation (FAR) does not apply to leasing actions.  GSA establishes regulations for lease of real property under the authority of 40 U.S.C. 490 note.
