NAICS 561210 – Facilities Support Services encompasses a broad spectrum of non-core operational services essential to maintaining federal and public infrastructure. This category includes building maintenance, groundskeeping, custodial services, waste management, security support, utility coordination, and facility operations management. These services enable government agencies to focus on mission-critical functions while outsourcing the day-to-day upkeep and logistical support of physical assets. In the federal contracting landscape, this NAICS code serves as a foundational enabler for mission continuity, particularly in high-traffic, mission-essential environments such as military installations, VA medical centers, and DHS border facilities. Top contractors in this sector include a mix of large primes and specialized small businesses, with RE-ENGINEERED BUSINESS SOLUTIONS, INC, AECOM TECHNICAL SERVICES, INC., and D2 GOVERNMENT SOLUTIONS, INC. leading in award volume. Other active players such as TMG THE MOORE GROUP INC, A-TEAM SOLUTIONS LLC, and PATRIOT CONSTRUCTION INC reflect a diverse ecosystem of firms offering integrated facility operations, maintenance, and logistical support services. Many of these contractors specialize in performance-based contracting models and are experienced in meeting stringent federal compliance standards, including OSHA, EPA, and DoD facility regulations. Key government buyers include the Department of Defense, Department of Veterans Affairs, Department of Homeland Security, and Department of Health and Human Services, with agencies like NAVSUP and Customs and Border Protection relying heavily on these services to sustain operational readiness. Demand is driven by the need for continuous, reliable facility operations in secure, high-availability environments, including medical facilities, detention centers, and logistics hubs. The competitive landscape is characterized by high entry barriers due to compliance requirements and contract complexity, but opportunities abound for firms with proven experience in federal facility management, energy efficiency programs, and integrated service delivery. Procurement trends favor long-term, performance-based contracts and increased emphasis on sustainability and resilience in facility operations.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 561210 work as a small business.

$47.0M
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
