FY2025 federal contract obligations, USAspending.gov
NAICS 561720 obligated $2.1 billion in FY2025 across 6,046 contract actions. DoD leads at $1.2 billion, but GSA at $356 million is the number that changes strategy, because that is federal building custodial work competed through the Public Buildings Service on a predictable regional cycle. DHS follows at $111 million, VA at $109 million, and DOT at $50 million.

Competing in this code
Two structural facts govern this code, and neither is size. First, a large share of federal custodial requirements are on the AbilityOne Procurement List and are not competed at all, so a solicitation you can actually bid is a smaller universe than the $2.1 billion suggests. Second, Service Contract Act wage determinations plus health and welfare set the labor cost floor identically for every bidder, which compresses price competition into productivity assumptions and management overhead. With 944 IDVs in the code, the durable position is a regional multiple-award contract with GSA or a service component, where you compete on task orders and never re-propose from scratch.
Frequently Asked
NAICS 561720 questions, answered.
What is the SBA size standard for NAICS 561720?
SBA sets it at $22 million in average annual receipts, averaged over your last five completed fiscal years. Come in at or under that and you are small on every NAICS 561720 solicitation, including the set-asides.
Which agencies buy janitorial services under NAICS 561720?
FY2025 obligations: DoD ($1.2 billion), GSA ($356 million), DHS ($111 million), VA ($109 million), DOT ($50 million). GSA's Public Buildings Service is the most reachable buyer for a commercial custodial firm, since its regional requirements recompete on a predictable cycle.
How does AbilityOne affect competition under NAICS 561720?
Substantially. Many federal custodial requirements sit on the AbilityOne Procurement List and are assigned to nonprofit agencies employing people who are blind or have significant disabilities rather than competed. The addressable share of the code's $2.1 billion is therefore smaller than the total suggests, and checking Procurement List status before pursuing a site is basic diligence.
What decides price competitiveness in federal janitorial contracts?
Not wages. Service Contract Act wage determinations and health and welfare rates apply identically to every bidder, so labor cost is fixed. Competition happens in productivity assumptions, supervisory ratio, supply and equipment cost, and management overhead. Bidders who try to win on wage rate are either non-responsive or non-performing.
