SBA size standards for construction (NAICS 236, 237 and 238)
The construction rows of the SBA size-standard table in 13 CFR 121.201, reproduced from eCFR with the figure, the code and the footnote printed in the official table.
eCFR checked as of 2026-10-29. Section last amended 2026-09-29. Rows: 33.
FGExperts does not determine whether any business is small. Figures here are the published standard and the arithmetic you enter. Affiliation is not computed. Under 13 CFR 121.103 the receipts and employees of affiliates are generally counted, and affiliation turns on control and judgment. Only the SBA or the contracting officer can determine size.
