NAICS Code for Facilities Management

Federal facilities management spans base operating contracts, installation support, custodial services, maintenance, and grounds care. GSA, DoD, VA, and DoE operate thousands of facilities across the country, and the contracts that keep them running flow through a specific set of NAICS codes with some of the highest size standards in federal contracting.

Primary NAICS codes for facilities management

561210: Facilities Support Services ($47M size standard) The core facilities management NAICS. Use this if you do combined operations for client facilities: janitorial, maintenance, grounds, security, mailroom, reception bundled together. Federal base operating contracts (BOCs) typically flow through this code.

561720: Janitorial Services ($22M size standard) Specifically for janitorial and custodial work. Use this if your primary service is cleaning rather than bundled facilities services.

561730: Landscaping Services ($9.5M size standard) For grounds maintenance, landscaping, and tree services. Much lower size standard — graduate fast.

238990: All Other Specialty Trade Contractors ($19M size standard) For specialty maintenance and trades that don't fit dedicated NAICS.

Secondary NAICS codes to consider

561110: Office Administrative Services ($12.5M) For administrative support services to federal facilities.

561612: Security Guards and Patrol Services ($29M) For facilities management firms whose work includes significant guard operations.

238210: Electrical Contractors ($19M) For specialty electrical maintenance.

238220: Plumbing, Heating, and Air-Conditioning Contractors ($19M) For specialty HVAC maintenance.

Which code should be your primary

Two questions.

Are you bundled or specialized? If you perform multiple facility services under a single contract (a typical BOC), primary under 561210. If you specialize in one service (janitorial only, landscaping only), primary under the specific NAICS.

What size standard gives you runway? 561210 has a $47M standard — one of the highest in federal contracting. 561720 is $22M. 561730 is $9.5M. Primary choice affects how long you remain small.

For fast-growing facilities firms, primary under 561210 (when the work mix supports it) significantly extends set-aside eligibility. A landscaping-only firm graduating out of small at $9.5M faces a very different competitive environment than a facilities firm at $47M.

Size standard considerations

Facilities NAICS range from $9.5M (landscaping) to $47M (facilities support). This 5x spread means positioning decisions have real size-standard consequences. A firm doing landscaping under contracts that could arguably be classified as facilities support should think carefully about which NAICS it primaries under.

SBA has specific rules on when bundled services qualify for 561210 vs being classified under the dominant component service. Typically, a contract with more than one service type and no dominant component (say, 40% janitorial, 35% grounds, 25% maintenance) qualifies for 561210. A contract that's 85% janitorial with light other work gets classified as 561720.

Federal demand snapshot

GSA operates the largest federal real estate portfolio and contracts extensively for facilities services. DoD base operating contracts (Army BOS, Navy BOS, Air Force BOS) are multi-year IDIQ vehicles worth billions.

VA facilities management — medical center operations, cemeteries, regional offices — is a consistent SDVOSB set-aside category under Vets First.

HUBZone set-asides are common across facilities contracts, particularly at DoD installations located in HUBZone designated areas.
