NAICS 236220 — Commercial and Institutional Building Construction

General contractors and design-builders constructing or renovating commercial and institutional buildings — offices, schools, hospitals, warehouses, and similar facilities. Most federal building work is solicited under this code, and it's where specialty subs find primes to bid to.

SBA size standard

$45.0M average annual receipts (13 CFR § 121.201, verified June 2026)

Why the standard matters

If your average annual receipts are under the standard, you can compete for small-business set-asides under this code — including 8(a), HUBZone, SDVOSB, and WOSB solicitations when your firm holds the certification.
