The Federal Acquisition Regulation and the General Services Administration

The Federal Acquisition Regulation runs to roughly two thousand pages, governs every dollar the United States government spends on goods and services through ordinary contracting channels, and is jointly maintained by three agencies that, on paper, have very little to do with one another: the Department of Defense, the National Aeronautics and Space Administration, and the General Services Administration. The arrangement is older than it looks and stranger than it sounds, and understanding GSA's specific corner of it requires a brief tour through how a regulation gets written when no single agency owns it.

What the FAR actually is

The Federal Acquisition Regulation is codified at Title 48 of the Code of Federal Regulations, which is a fact more often stated than absorbed. Title 48 is, in administrative law, the volume reserved for federal procurement rules. The FAR proper occupies Chapter 1 of that title; subsequent chapters hold agency-specific supplements such as the Defense FAR Supplement (DFARS) at Chapter 2 and the GSA Acquisition Manual (GSAM, formerly GSAR) at Chapter 5. The canonical, current text of the FAR is hosted at Acquisition.gov, which is itself operated by GSA on behalf of the FAR Council.

The regulation governs the full lifecycle of a federal contract: how requirements are written, how competitions are advertised, what clauses must be inserted into solicitations, what cost principles apply, how disputes are resolved, and what happens when something goes wrong. It applies, with various carve-outs, to executive branch agencies. Certain entities, the Postal Service and parts of the intelligence community among them, sit outside its reach or follow parallel rules. Edge cases of this sort are common in procurement law and tend to be where the interesting arguments happen.

The FAR Council, and why three agencies share a regulation

The FAR is issued under the authority of the Office of Federal Procurement Policy Act, codified in 41 U.S.C., which created the Federal Acquisition Regulatory Council, more economically known as the FAR Council. The Council has four statutory members: the Administrator for Federal Procurement Policy (who chairs it), the Secretary of Defense, the Administrator of NASA, and the Administrator of General Services. The presence of NASA on a body that governs janitorial contracts and office furniture purchases is a small monument to the politics of 1974, when the FAR's predecessor regulations were being consolidated and NASA, then a young and influential buyer of complex systems, secured a permanent seat.

Beneath the Council sit two working bodies that do most of the actual drafting. The Defense Acquisition Regulations Council (DARC) handles the military side. The Civilian Agency Acquisition Council (CAAC) handles everything else, and is chaired by GSA. CAAC representation includes most of the major civilian buying agencies — Treasury, Energy, Health and Human Services, Veterans Affairs, and so on — but the chair sits at GSA, and the secretariat work, the meeting logistics, and the institutional memory of civilian procurement policy reside there as well.

The practical consequence is that when a new FAR rule is contemplated, two councils must agree on the text. A proposed rule is drafted, often by a team drawn from both DARC and CAAC, published in the Federal Register for public comment, revised, and then issued as a Federal Acquisition Circular, which is the document that actually amends the FAR. This is slower than rulemaking inside a single agency. It is also, by design, less prone to producing rules that work for the Air Force but not for the Forest Service.

What GSA contributes, specifically

GSA's role in maintaining the FAR is not merely procedural. Three contributions are worth describing in plain terms.

The first is the chair of CAAC, which means GSA effectively coordinates the civilian agencies' position on every proposed FAR amendment. When a rule is technically optional in scope but politically charged — sustainable acquisition, for instance, or domestic content thresholds — GSA's CAAC team is where civilian agency objections are reconciled into a single voice that can sit across the table from DoD.

The second is the publishing infrastructure. Acquisition.gov, per GSA's own descriptions of the site, hosts the integrated, searchable text of the FAR along with archived versions, the open FAR cases that are currently in drafting, and the Federal Acquisition Circulars that have amended the regulation over time. The site is a GSA product, not a Council product, even though it serves the Council. The distinction matters mostly when something breaks and someone has to fix it.

The third is the GSAM, the GSA Acquisition Manual, which is the agency-specific supplement that GSA contracting officers follow when they are buying things on behalf of GSA itself or running the Multiple Award Schedule program. The GSAM cannot contradict the FAR, and where it adds requirements it must justify them; this is the same constraint DoD operates under with the DFARS. The GSAM is published in Chapter 5 of Title 48 CFR.

Recent areas of FAR activity

The FAR is amended several times a year, and a complete inventory of recent rules would be tedious. A few clusters, though, illustrate where the regulation has been moving.

Domestic preference rules have been an active area. The Buy American Act, which dates to 1933, sets domestic content thresholds for federal procurement, and successive administrations have raised those thresholds and tightened the definition of what counts as a domestic end product. The FAR clauses that implement Buy American — and the related, often confused Trade Agreements Act clauses, which apply different rules above certain dollar thresholds for products from designated countries — have been revised multiple times in recent years to reflect executive orders on domestic sourcing. The mechanics are intricate. Whether a particular laptop counts as American-made depends on where its components were manufactured, where it was substantially transformed, what the contract's dollar value is, and whether the buying agency has a waiver. None of this is GSA-specific, but GSA, as the operator of the Schedules program through which a great deal of commercial product procurement flows, has had to update its solicitations and its vendor guidance accordingly.

Cybersecurity is another. The FAR has, for some time, contained clauses on safeguarding contractor information systems and reporting cyber incidents, and proposed rules in recent years have sought to expand those obligations across civilian procurement, partly in response to incidents involving federal supply chains and partly in alignment with the Cybersecurity and Infrastructure Security Agency's broader policy posture. CAAC, with GSA in the chair, has been a forum where civilian agencies have shaped what those expanded clauses ought to look like.

Sustainability rules — the ones that govern energy efficiency standards, recycled content, biobased products, and disclosures of greenhouse gas emissions by contractors — have likewise moved. The FAR's sustainable acquisition framework draws on a tangle of underlying authorities, including statutes administered by the Environmental Protection Agency and the Department of Energy. Proposed amendments in this area tend to generate substantial public comment, both supportive and critical, and the resulting Federal Acquisition Circulars often look quite different from the original notice of proposed rulemaking.

The regulation as text, and where to read it

The full FAR, in its current form, is at acquisition.gov/far. It is organized into 53 parts, grouped into eight subchapters that move roughly in the order a procurement unfolds: general provisions, acquisition planning, contracting methods and contract types, socioeconomic programs, general contracting requirements, special categories of contracting, contract management, and clauses and forms. Reading it cover to cover is something almost no one does and almost no one needs to do; what most practitioners do instead is develop an instinct for which Part to consult for which question. Part 12 covers commercial item acquisition. Part 15 covers negotiated procurements. Part 19 covers small business programs. Part 52 contains the actual clause text that gets pasted into solicitations.

The structure is, on close inspection, a slightly absurd pile of definitions invented by humans, but it is internally consistent, and the cross-references mostly work. Where a clause refers to another clause, the citation is precise; where a definition applies only within a specific part, the part says so at the top. This is unfashionable virtue, but it is virtue.

Where the FAR meets the rest of GSA's work

GSA's FAR responsibilities are easier to understand alongside what the agency actually buys and operates. The Federal Acquisition Service runs the Multiple Award Schedule, the Government-wide Acquisition Contracts (GWACs) for information technology, GSA Advantage as a catalog ordering channel, GSA eBuy for solicitations against Schedule contracts, and the Reverse Auctions platform. Each of these vehicles is built on top of FAR authorities, particularly Parts 8 and 16 governing ordering against indefinite-delivery contracts, and each has its own implementing guidance in the GSAM.

The Public Buildings Service, on the real estate side, conducts construction and leasing acquisitions under the FAR and under 40 U.S.C., the title that vests GSA with its public buildings authority. The P100 Facilities Standards govern design and construction quality for federal buildings GSA manages, and those standards are referenced in construction solicitations as technical requirements rather than as FAR clauses, which is a useful distinction to keep in mind.

Identity and registration infrastructure sits adjacent to the FAR rather than inside it. SAM.gov, operated by GSA, is the system in which entities must register before they can receive a federal contract; the registration requirement itself is a FAR provision (FAR 4.1102), but the system is GSA's. Login.gov provides identity services for SAM and many other federal applications. None of this is FAR text, but the FAR depends on it functioning.

A note on what the FAR is not

The FAR is not the entire law of federal contracting. Above it sits statute — primarily Title 41 of the U.S. Code for civilian agencies and Title 10 for defense — which the FAR implements and cannot override. Below it sit agency supplements, internal policy memoranda, and the case law of the Court of Federal Claims, the boards of contract appeals, and the Government Accountability Office's bid protest decisions. A contracting officer reading only the FAR is reading perhaps sixty percent of what governs a given decision. This is worth saying because the regulation's prominence sometimes gives the impression of completeness it does not actually claim.

GSA's role, in this larger picture, is partly to keep the FAR coherent across the civilian agencies that use it, partly to publish it in a form that practitioners can actually read, and partly to operate the procurement vehicles and infrastructure systems through which a substantial fraction of federal buying flows. The work is unglamorous, mostly invisible to the public, and quietly consequential.
