HUBZone Certification: Requirements and Application Guide
The HUBZone program helps small businesses in historically underutilized areas access federal contracting opportunities. Certified HUBZone firms can compete for set-aside contracts, receive a 10% price evaluation preference in full-and-open competitions, and access sole-source awards.
This guide covers the geographic and employment requirements, how to verify your location on the HUBZone map, the Certify.gov application process, and ongoing compliance obligations.

1. Principal Office Requirement
Your principal office must be located in a designated HUBZone. The principal office is the location where the greatest number of your employees perform their work. If most employees work in the field or remotely, the principal office is the location where business administration and management functions are performed.
The principal office must be a physical location — a P.O. Box or virtual office does not qualify. You must have a lease, deed, or other documentation proving your presence at the address. The SBA may conduct site visits to verify your principal office location. If you operate from a home office, it can qualify as long as the address is in a HUBZone and it is truly your principal place of business.
It is important to distinguish the principal office from other business locations. If you have multiple offices, only one needs to be in a HUBZone, but it must be the one where the most employees work or where management functions are centered. Satellite offices, warehouses, or job sites in non-HUBZone areas do not affect eligibility as long as the principal office requirement is met.
2. 35% Employee Residency Rule
At least 35% of your total employees must reside in a HUBZone. This is one of the most challenging requirements to maintain, especially as your company grows.
Who Counts as an Employee?
The 35% calculation includes all individuals on your payroll: full-time, part-time, and temporary employees. Independent contractors are generally not counted unless they work exclusively for your company and the relationship meets certain criteria that make them functionally equivalent to employees. Leased employees from staffing agencies are included in the count.
Residence Verification
Each employee's primary residence must be verified against the HUBZone map. Use the SBA HUBZone map tool to check each address. You should maintain records of employee addresses and periodically verify them, especially after employees move. Acceptable documentation includes driver's licenses, utility bills, lease agreements, or other proof of residence.
Managing the Ratio
As you hire new employees, be mindful of the 35% ratio. If you have 20 employees, at least 7 must live in a HUBZone. If you grow to 50, at least 18 must. Consider targeting your recruiting to HUBZone areas and making HUBZone residency a factor in hiring decisions (to the extent permissible under employment law). Some companies offer relocation incentives to help employees move into HUBZone areas.
3. HUBZone Map Verification
The SBA maintains an interactive HUBZone map that is the definitive tool for verifying whether an address is in a designated HUBZone. You should use this map to verify both your principal office address and employee home addresses before applying.
Types of HUBZone Designations
- ●Qualified Census Tracts: Low-income areas as defined by HUD
- ●Qualified Non-Metropolitan Counties: Counties with median household income below thresholds or unemployment above national average
- ●Indian Reservations: Lands within any Indian reservation
- ●Base Closure Areas: Areas surrounding military bases closed under the Base Realignment and Closure Act
- ●Governor-Designated Areas: Areas designated by state governors and approved by the SBA
- ●Disaster Areas: Qualified areas following major disaster declarations
Save screenshots or printouts of your map verification results. The SBA may ask for documentation showing your addresses were in a HUBZone at the time of application. HUBZone boundaries can change with census data updates, so re-verify periodically and especially before recertification.
4. Application Process on Certify.gov
HUBZone certification applications are submitted through the SBA's Certify.gov portal. The SBA targets processing times of 60 days for complete applications.
Required Documents
- ●Lease agreement or deed for your principal office
- ●Complete employee list with home addresses, job titles, and full-time/part-time status
- ●Payroll records or tax forms (W-2s or 1099s) verifying employment
- ●Proof of HUBZone residency for qualifying employees (driver's license, utility bills)
- ●Organizational documents (articles, operating agreement, bylaws)
- ●Proof of U.S. citizenship for owners (for at least 51% ownership)
- ●Business tax returns (most recent year)
After creating your Certify.gov account and linking your SAM.gov entity, select the HUBZone certification program. Complete each section, upload documents, and submit. The SBA may conduct a site visit to verify your principal office location and may contact employees to verify residency. Respond promptly to all SBA inquiries to avoid delays.
5. Recertification and Compliance
HUBZone certification must be recertified annually through Certify.gov. The SBA also requires recertification whenever a certified firm is being considered for a HUBZone contract award, and the SBA may conduct program examinations at any time.
Annual Recertification
Each year, you must log into Certify.gov and confirm that your principal office is still in a HUBZone and that at least 35% of your employees still reside in HUBZones. Update any changes to your employee list, addresses, or business structure. Set a reminder 30 days before your recertification deadline to gather updated documentation.
Contract Award Recertification
When a contracting officer proposes to award a HUBZone set-aside contract to your firm, you must recertify your HUBZone status at that time. This means your 35% residency ratio and principal office location must be compliant at the point of award, not just at initial certification. If you cannot recertify at the time of award, you may lose the contract opportunity.
Compliance Monitoring
The SBA conducts periodic program examinations (site visits and document reviews) of certified HUBZone firms. During an examination, the SBA verifies your principal office, employee addresses, ownership, and size status. Firms found not in compliance may be decertified and prohibited from reapplying for a specified period. Maintain organized records of employee addresses, payroll, and lease documents at all times.
6. Redesignation and Graduated HUBZones
HUBZone designations are not permanent. Areas can lose their HUBZone status when census data changes, economic conditions improve, or base closure areas exceed their eligibility period. This is called redesignation.
What Happens When Your Area Is Redesignated
If your principal office or employee residences are in areas that lose HUBZone designation, you may qualify for “graduated HUBZone” status. Under graduated status, you remain eligible for HUBZone set-aside contracts for up to three years. However, the price evaluation preference is reduced during the graduated period. This gives you time to either relocate to a current HUBZone or adjust your business strategy.
Planning Ahead
Monitor the SBA HUBZone map for upcoming redesignation changes. The SBA publishes advance notice of areas that will be redesignated. If your area is scheduled for redesignation, consider relocating your principal office to an area that will retain its HUBZone status. Similarly, factor HUBZone locations into your hiring strategy to maintain the 35% residency requirement after boundary changes.

Frequently Asked Questions
What is a HUBZone?
HUBZone stands for Historically Underutilized Business Zone. These are designated geographic areas including qualified census tracts, qualified non-metropolitan counties, lands within Indian reservations, qualified base closure areas, qualified disaster areas, and Governor-designated areas. The SBA maintains an interactive HUBZone map that shows all designated areas. HUBZone designation encourages economic development in distressed communities by directing federal contract dollars to businesses located in and employing residents of these areas.
How do I check if my address is in a HUBZone?
Use the SBA HUBZone map at maps.certify.sba.gov/hubzone/map. Enter your business address to see if it falls within a designated HUBZone. You should also check employee home addresses to verify they meet the 35% residency requirement. HUBZone designations change periodically based on census data, economic conditions, and other factors, so verify addresses regularly. The map shows the type of HUBZone designation (qualified census tract, non-metropolitan county, Indian lands, etc.) and any upcoming redesignation dates.
What happens if my area loses its HUBZone designation?
If your principal office or employee residences lose HUBZone designation due to redesignation, you may enter a "graduated HUBZone" status. Graduated HUBZone firms maintain eligibility for HUBZone set-aside contracts for up to three years after redesignation, but at a lower price evaluation preference (less than the 10% offered to fully qualified HUBZone firms). During this period, you should plan to either relocate to a current HUBZone or transition your business strategy to rely less on HUBZone set-asides.
Can I have employees who do not live in a HUBZone?
Yes. The requirement is that at least 35% of your total employees reside in a HUBZone — not that all employees must live in one. You can have up to 65% of your workforce living outside HUBZones. However, managing this ratio requires ongoing attention, especially as you hire new employees or existing employees move. Each time you recertify or when the SBA conducts a review, you must demonstrate that at least 35% of your employees (including all full-time, part-time, and leased employees) reside in a HUBZone.
