Small-business programs
What is HUBZone certification?
Historically Underutilized Business Zone program
HUBZone is an SBA program for small businesses whose principal office is located in a Historically Underutilized Business Zone and at least 35% of whose employees live in a HUBZone, and certification makes a firm eligible for HUBZone set-aside and sole-source contracts.
Also written as: HUBZone certification, hub zone, HUBZone eligibility.
SBA states the requirements as: a small business at least 51% owned and controlled by U.S. citizens, a Community Development Corporation, an agricultural cooperative, an Alaska Native corporation, a Native Hawaiian organization or an Indian tribe; a principal office located in a HUBZone; and at least 35% of employees living in a HUBZone. The government's stated goal is 3% of all federal prime contracting dollars to HUBZone firms.
Unlike the other programs, HUBZone is geographic and therefore mutable. Designated areas are redrawn as the underlying data changes, so an address that qualifies today may not qualify at the next redesignation, and one that does not qualify now may later. SBA's HUBZone map is the authority for any specific address — nothing else is.
The 35% employee-residency test is the part firms most often fail on and the part they have most control over. It is a continuing obligation, not a one-time check at certification.
What this means when you bid
Verify your exact address on SBA's HUBZone map, not the neighbourhood or the ZIP code. Qualification is parcel-level and it changes.
