HUBZone Certification for Construction & Trades Companies

For small businesses located in Historically Underutilized Business Zones.

Construction is one of the most certification-driven industries. Here's why it matters:

Federal Requirements: The Department of Transportation requires state DOTs to award a percentage of federally-funded contracts to Disadvantaged Business Enterprises (DBEs). This creates billions in set-aside opportunities annually.

Tier 1 Subcontracting: Major general contractors like Turner, Skanska, and Gilbane have aggressive diversity goals. They actively seek certified diverse subcontractors to meet their contractual obligations on large projects.

Bonding Advantages: Many certification programs offer bonding assistance and surety support, helping smaller contractors qualify for larger projects.

State and Local Set-Asides: Most states have MBE/WBE goals for public construction projects, creating additional opportunities beyond federal contracts.

The construction industry awarded over $45 billion to diverse contractors in the last fiscal year, making it one of the largest opportunity areas for certified diverse businesses.

Principal office must be in a HUBZone, 35% of employees must reside in a HUBZone.

HUBZone certification has three hard requirements: principal office location, employee residency, and ownership. All three must be met at the time of certification and maintained continuously.

Principal office location The business's principal office (where the majority of employees report, where management works, and where the most business activity occurs) must be located in a qualified HUBZone. A P.O. box, virtual office, or registered-agent address does not qualify. Verify the exact street address at maps.certify.sba.gov before doing anything else. HUBZone maps are updated annually; an address that qualified last year may not qualify today.

Employee residency (the 35% rule) At least 35% of your employees, counted by headcount, must live in a HUBZone. The percentage is computed on the number of employees and rounded to the nearest whole number: 10 employees means at least 4 must reside in a HUBZone (25 employees means 9). Hours matter only for deciding who counts as an employee; anyone who generally works a minimum of 10 hours per week during the four-week period before review counts, including part-time workers. SBA can examine payroll records and require employees to document their residential addresses with utility bills or driver's licenses.

Ownership The business must be 51% owned and controlled by one or more U.S. citizens, a Community Development Corporation, an agricultural cooperative, or a Native American tribe or Alaska Native Corporation (ANC). Tribally-owned and ANC-owned firms face no SBA size restrictions.

Size The firm must qualify as small under SBA size standards for its primary NAICS code. Verify at sba.gov/size-standards.

Step 1: Verify the principal office address Go to maps.certify.sba.gov and enter your exact business street address. Do this before anything else. HUBZone designations are updated every year; the map reflects the current status. If your address does not qualify, stop here and evaluate whether relocating the principal office makes business sense.

Step 2: Calculate the 35% employee residency ratio Pull your most recent payroll records. List every employee and their home address, and confirm who counts as an employee (generally anyone working at least 10 hours per week in the four weeks before review). For each employee, check whether their home address falls in a HUBZone using the same map tool. Calculate: HUBZone-resident employees ÷ total employees, rounded to the nearest whole number of required residents. If the result is below 35%, you are not currently eligible. Document this calculation; SBA may ask for it.

Step 3: Confirm SAM.gov registration is active HUBZone applications require an active SAM.gov registration. Confirm it's current and lists your HUBZone office address as your primary place of business.

Step 4: Gather documentation Before opening the certify.sba.gov application, have these ready: a signed lease or deed for the principal office address; proof of employee home addresses (driver's licenses, utility bills dated within 90 days); payroll records showing hours by employee; ownership documents (operating agreement, stock certificates, or membership ledger); and business tax returns for the past two years.

Step 5: Submit the application at certify.sba.gov The online application asks for business details, employee data, and document uploads. Be precise about how you calculate the 35%; SBA reviewers check the math.

Step 6: SBA review SBA targets a 60-90 day review period. Incomplete applications or address conflicts will trigger a request for additional information. Respond within 15 days.

Step 7: Program examination and ongoing compliance After certification, SBA can conduct a program examination at any time to verify continued eligibility. Maintain a residency log for all employees. If any employee moves out of a HUBZone, recalculate your ratio immediately. If a redesignation removes your office area from HUBZone status, you have a 3-year transition period during which you remain certified (per SBA redesignation rules).

Federal Opportunities

The federal government is the largest buyer of construction services. Key agencies include:

• Department of Transportation (DOT): Manages the DBE program for highway, transit, and airport construction
• Army Corps of Engineers: Billions in civil works, military construction
• General Services Administration (GSA): Federal building construction and renovation
• Department of Defense: Military base construction worldwide

How to Access: Register in SAM.gov, get your NAICS codes certified, and monitor opportunities on SAM.gov and agency-specific portals.

State and Local

Every state has a transportation department with DBE requirements. Many also have state-funded MBE/WBE programs for building construction and public works.
