Run a HUBZone map eligibility check on your office and employee addresses, read the designation type, and learn which green pins expire first. The SBA HUBZone map tells you whether one address sits inside a zone today. It never answers the 35 percent employee test, and five separate clocks decide how long each designation lasts. Open the SBA HUBZone map (https://maps.certify.sba.gov/hubzone/map), type an address, and read what comes back. That is the whole mechanical part of a HUBZone map eligibility check. The map answers one question: does this point sit inside a designated area right now. It does not tell you whether your firm qualifies. Certification needs two separate findings under 13 CFR 126.200, and the map helps with only one of them. It also hides a timing problem. Five different refresh clocks govern the designations, so a green result today can vanish before your next recertification. The HUBZone Map Eligibility Check Run the check twice, for two different reasons. First, enter your principal office address. SBA tells firms to "Check the HUBZone map to determine whether your principal office and employees are located in a HUBZone." Second, enter the home address of every employee. Those results feed a headcount, not a yes or no. Read the designation type, not just the shading. The map labels each qualifying area with one of seven categories. Four of them are a Qualified Census Tract, a Qualified Non-Metropolitan County, a Redesignated Area and a Qualified Base Closure Area. The other three are a Qualified Disaster Area, Indian lands and a Governor-Designated Covered Area. Those labels carry very different lifespans. Write down which one applies to your office before you do anything else. Use SBA's own map, and nothing else. Third-party lookup tools copy a snapshot and go stale quietly. SBA runs the map that its certification analysts read, so that is the only result worth keeping in a file. ! Five HUBZone designation types with how long each one stays on the SBA map, from a disaster area lasting only until the next update to a base closure area at eight years (https://mhhifytmrlyksfrjacvi.supabase.co/storage/v1/object/public/blog-images/2026/10/hubzone-map-eligibility-check-figure.png) The two shortest-lived designations are also the two that get no long-term lease protection. Two Tests, One Map 13 CFR 126.200(c) sets the first test: "a concern's principal office must be located in a HUBZone." 13 CFR 126.103 then defines principal office as "the location where the greatest number of the concern's employees at any one location perform their work."
