Small Business Set-Asides for Cleaning Contracts

Janitorial services sit in NAICS 561720, a code with a $22 million average-annual-receipts size standard under the SBA's current Table of Size Standards, a threshold generous enough that most independent BSCs qualify as small businesses even after a decade of growth. That size classification is what makes the entire federal set-aside system available, a structure built into the FAR that reserves specific dollar bands and specific contract types for small businesses before large contractors are ever allowed to compete.

How the dollar-tier system actually works

The FAR's small business set-aside mechanism is not a single rule. It is a series of dollar thresholds that change how a contracting officer is required to structure competition. Below the simplified acquisition threshold, acquisitions are automatically reserved for small business unless the contracting officer cannot find at least two small firms likely to bid. Above that threshold, the officer must still consider a set-aside if market research shows a reasonable expectation of receiving offers from two or more small businesses at a fair price, a rule known informally as the "rule of two." Only if that expectation fails does the acquisition open to full and open competition.

Within the small business universe, contracting officers must also consider socio-economic set-aside categories (8(a), HUBZone, WOSB, and SDVOSB) before defaulting to a general small business set-aside, following a specific order of consideration set out in FAR Part 19. A janitorial company holding one of these certifications is competing in a narrower, often less crowded field than general small business status alone provides.

What the rule of two means for your bid strategy

Contracting officers are required to conduct market research before soliciting a janitorial contract, and that research is what determines whether the rule of two is satisfied. Practically, this means the government is actively looking for evidence that small janitorial firms exist and can perform, a step that rewards contractors who make themselves visible in SAM.gov with an accurate NAICS 561720 profile and responsive capability statements when contracting officers issue sources-sought notices. A company that never registers or never responds to a sources-sought notice is invisible to the market research that decides whether a set-aside happens at all.

Above the simplified acquisition threshold, subcontracting plans become a separate lever: prime contracts awarded to large businesses above defined dollar thresholds generally must include a subcontracting plan with small business participation goals, which is why a certified small or socio-economically disadvantaged janitorial firm can find real subcontracting opportunities even on primes it could not win outright.

8(a) and HUBZone: where the numbers matter most

The 8(a) program runs on a 9-year term split into a four-year developmental stage and a five-year transitional stage, with sole-source award authority available up to defined dollar thresholds that are higher for manufacturing NAICS codes than for service codes like 561720, meaning a janitorial 8(a) firm's sole-source ceiling is the lower, services-based threshold, not the manufacturing figure. HUBZone eligibility requires that the firm's principal office sit inside a HUBZone-designated area and that at least 35 percent of employees reside in a HUBZone at the time of certification and throughout contract performance, a residency requirement that creates real operational constraints for a cleaning company scaling staff across multiple job sites, since new hires outside the zone can erode the ratio over time if not offset by zone-resident hiring.

WOSB and EDWOSB: an underused lane for cleaning companies

The Women-Owned Small Business program set aside a defined share of federal contracting dollars in industries the SBA has identified as underrepresented for women-owned firms, and janitorial services has appeared among eligible NAICS codes in various program cycles. A firm at least 51 percent owned and controlled by one or more women can self-certify or obtain third-party certification; the Economically Disadvantaged WOSB (EDWOSB) tier adds personal net worth, income, and asset limits similar in structure to the 8(a) program's economic disadvantage test, and carries sole-source authority up to defined thresholds that general WOSB status does not. Cleaning companies that qualify and have not pursued this certification are often leaving a real set-aside lane unused, particularly at agencies actively working to hit their own WOSB participation goals.

Stacking certifications without overcomplicating the bid

A janitorial firm eligible for multiple set-aside categories does not need to lead every proposal with every certification it holds. Lead with whichever certification is most relevant to the specific solicitation's set-aside type, and mention secondary certifications briefly where they strengthen a past performance or teaming narrative. Contracting officers evaluating a HUBZone set-aside are checking HUBZone eligibility specifically; burying that qualification under an unrelated SDVOSB narrative can cost you clarity where it matters most. Keep a one-page certification summary current and ready to attach to any proposal, listing certification type, certifying body, effective date, and NAICS codes covered, so you are never scrambling to document status under a submission deadline.

Watching for sources-sought notices, not just open solicitations

Contracting officers frequently issue a sources-sought notice before an RFP is finalized specifically to gather the market research the rule of two depends on, and this notice window is where a small janitorial company has real influence over whether a contract ends up set aside at all. Responding to a sources-sought notice with a capability statement showing relevant square footage experience, current certifications, and bonding capacity gives the contracting officer concrete evidence that small businesses can perform the work, directly supporting a set-aside determination. Companies that wait for the RFP itself to appear have already missed the stage where their input could shape whether the opportunity was set aside in the first place.

Frequently asked questions

Can a company hold more than one certification at once? Yes. A firm can be simultaneously certified as HUBZone, WOSB, and SDVOSB if it meets each program's independent eligibility test, and stacking certifications widens the set-aside pool a company can compete in.

Does exceeding $22 million in receipts disqualify a janitorial company immediately? Size standard determinations look at average annual receipts over a defined period (typically the most recent five years), not a single year, so a temporary spike does not automatically disqualify a firm; sustained growth above the standard does.

What happens if no small businesses respond to a set-aside solicitation? The contracting officer can cancel the set-aside and re-solicit under full and open competition if market research turns out to have been inaccurate, though this is treated as an exception requiring documentation, not a routine option.

Is a subcontracting plan required on every large-business janitorial prime contract? Only above specified dollar thresholds for non-construction contracts; below that threshold, subcontracting plans are not a mandatory requirement, though many agencies still encourage small business participation.
