HUBZone program basics

The HUBZone program helps small businesses in historically underutilized business zones win federal contracts through set-asides and a price preference. Unlike the other SBA programs, it is built around location: where your principal office is and where your employees live. That makes it unusually open, since it does not depend on the owners' gender, veteran status or economic background, but it also makes it unusually sensitive to change, because maps get redrawn and employees move. This guide explains who qualifies, what certification gets you, how to keep it, and how to decide whether it is worth pursuing.

What a HUBZone is

HUBZone stands for Historically Underutilized Business Zone. The designations come from several sources, including qualified census tracts, qualified non-metropolitan counties, Indian lands, certain base closure areas, redesignated areas, governor-designated covered areas and qualified disaster areas. SBA publishes all of them on the HUBZone map, where you can enter an address and see whether it qualifies. The government aims to award at least 3% of federal prime contracting dollars to HUBZone small businesses each year, according to SBA's HUBZone program page.

Who qualifies

SBA lists four core requirements. The business must be small under SBA size standards. It must be 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. Its principal office must be located in a HUBZone. And at least 35% of its employees must live in a HUBZone. The full criteria are in Title 13, Part 126, Subpart B of the Code of Federal Regulations.

The principal office is the location where the greatest number of your employees perform their work, which is not necessarily where the owner sits or where the business is legally registered. The 35% residency rule counts employees, not payroll, and it applies to where employees live, not where they work. Both tests are checked against the current map.

A hypothetical example shows how the two tests interact. A twelve-person landscaping company has its yard and office in a qualified census tract, so the principal office test is met. To meet the residency test, at least five of its twelve employees (35% of twelve is 4.2, and you cannot have a fraction of a person) must live in any HUBZone, not necessarily the same one. If two of those employees move to non-HUBZone addresses, the firm could fall below the threshold. Firms that rely on the program therefore tend to track employee addresses as carefully as they track payroll.

Benefits

Certified firms can compete for HUBZone set-aside contracts and sole-source awards that are closed to everyone else. They also get a 10% price evaluation preference in full and open competitions, which no other SBA program offers. In practice, when a HUBZone firm competes against large businesses in an unrestricted competition where the preference applies, the evaluators add 10% to the other offers' prices for comparison purposes, subject to the detailed rules in FAR Subpart 19.13, which, among other things, do not apply the factor to offers from other small businesses. The preference does not apply in every situation, and the solicitation will say when it does.

HUBZone firms can also compete in any other program they qualify for. FAR 19.203 gives no order of precedence among the 8(a), HUBZone, SDVOSB and WOSB programs, so a firm that is also, say, women-owned and certified can pursue both kinds of set-aside.

Like all set-aside winners, HUBZone contractors must follow the limitation on subcontracting in FAR 52.219-14, which also applies to contracts won using the HUBZone price evaluation preference unless the firm waived the preference. On a services contract, for example, the firm generally may not pay more than 50% of the amount paid by the government to subcontractors that are not similarly situated, meaning not also HUBZone-certified small businesses.

Applying

Applications are free and are made through SBA Certifications, where you can also find checklists and a pre-application eligibility check. You will need an active SAM.gov registration first. Expect to document ownership, the principal office location and employees' residence addresses, along with proof that the people you count are genuinely your employees.

Keeping certification

According to SBA, HUBZone firms recertify every three years, and there is no limit to how long a business can participate as long as it continues to qualify. Businesses must notify SBA if they are involved in a merger or acquisition. SBA may also conduct unannounced site visits and program examinations to verify the information a firm provided.

The map itself changes. SBA must update HUBZone designations periodically; it notes that the map was last updated in 2023 and is next due for updates at some point in 2026, to reflect expiring redesignated areas, and in July 2028, to reflect changes to qualified census tracts and qualified non-metropolitan counties. Governor-designated covered areas and qualified disaster areas can change in any year. If your office or your employees' homes sit in an area slated to change, plan ahead.

Common mistakes

Several mistakes catch HUBZone applicants and participants. One is assuming that a home or office address that qualified years ago still qualifies; always check the current map before applying and before recertifying. Another is counting people who are not really employees, such as owners who do no work or contractors paid on a 1099 basis, without checking how SBA's rules treat them. A third is forgetting that the 35% test is a continuing obligation rather than a one-time hurdle, so a hiring push in a non-HUBZone area can quietly push a firm out of compliance. A fourth is treating certification as a guarantee of work. Like every SBA program, HUBZone certification gives you access to certain competitions, but you still need to find the opportunities and submit a winning offer.

Is HUBZone right for you?

The program is a strong fit for small firms that already operate in or near designated areas and hire locally. It is a harder fit for firms whose workforce is spread out or who would need to relocate just to qualify. Look at the work, too: browse current HUBZone set-aside opportunities and filter by your industry and your state to see how often agencies use the program for the kind of work you do. For a broader comparison, read HUBZone, WOSB, SDVOSB and 8(a) set-asides compared.
