How much is set aside for small businesses
Small businesses received 32.3% of janitorial contract money in FY2025, by their status on each contract. Set-asides reserve part of the work outright. By the set-aside each contract reported:
- Small business set-aside (total): $125.4 million.
- 8(a) sole source: $116.0 million; 8(a) competed: $77.2 million.
- Service-disabled veteran-owned (SDVOSB) set-aside: $85.4 million competed, $4.3 million sole source.
- Women-owned and economically disadvantaged women-owned (WOSB, EDWOSB): about $6.1 million.
- HUBZone: $4.8 million.
- No set-aside: $904.5 million; set-aside not reported: $782.7 million (often orders under existing contracts, which follow the parent contract's terms).
A broad market, mostly bought contract by contract
1,551 companies received janitorial money in FY2025. The largest, Didlake Inc., had 3.4% of it, and the market's concentration index (HHI) was 107, far below the 1,500 that marks a concentrated market: no company dominates.
Most of the money went through standalone contracts ($900.7 million) and single-award IDIQs ($746.8 million), each held by one company. Shared vehicles open to several holders carried less: multiple-award IDIQs $85.8 million, blanket purchase agreements $52.0 million and GSA Schedule orders $3.3 million, about 6.7% together. For a new company that means most janitorial work is reachable through ordinary solicitations, without first winning a place on a vehicle.
Who counts as small for janitorial work
The SBA size standard for NAICS 561720 is average annual receipts of $22 million or less, averaged over the last five completed fiscal years and counting affiliates (13 CFR 121.201 and 121.104). SBA proposed new size standards in August 2026; until a final rule takes effect, $22 million applies. A solicitation's NAICS code sets the standard you are measured against.
Some custodial buys are coded by product and service code S201 (Housekeeping: custodial janitorial) under a different NAICS code, so a search by NAICS alone can miss them.
