XL EagleRule of Two (Small business Rule of Two)
Rule of Two stands for Small business Rule of Two. The Rule of Two says a contracting officer should set aside a contract for small businesses when there is a reasonable expectation that at least two responsible small businesses will submit offers at fair market prices. It comes from the Federal Acquisition Regulation and court decisions interpreting it.
The FAR is being rewritten under an overhaul started in 2025, and agency deviations have changed how the rule applies to some orders under multiple-award contracts. The core idea remains, but check the current agency rules for specifics.
Why it matters to a small contractor
Responding to 'sources sought' notices and market research surveys is how you help trigger the Rule of Two. If no small firms respond, the agency may open the contract to large businesses instead.
Example
An agency posts a sources sought notice for grounds maintenance. Four small landscaping companies respond with capability statements, and the contracting officer decides to set the contract aside for small businesses.
Rule of Two: common questions
Does the Rule of Two apply to every purchase?
No. It has exceptions and special rules, including for some orders under existing multiple-award contracts. Purchases in a certain dollar range are also generally reserved for small businesses.
How can I make sure my response counts?
Answer every question in the sources sought notice, show relevant past work, and confirm your size under the listed NAICS code.
