Frequently Asked Questions
What is a HUBZone set-aside?
A HUBZone (Historically Underutilized Business Zone) set-aside is reserved for businesses located in designated HUBZone areas — typically rural, urban, or Native American lands with low income or high unemployment. HUBZone firms also receive a 10% price evaluation preference in full-and-open competition.
How do I get HUBZone certification?
Apply through the SBA's certify.sba.gov portal. Requirements: principal office must be in a HUBZone, at least 51% owned by U.S. citizens (or qualifying entities), and at least 35% of employees must reside in a HUBZone. Use the SBA's HUBZone map at maps.certify.sba.gov to verify your address qualifies.
