HUBZone Eligibility Requirements
Principal office means the location where the greatest number of the concern's employees at any one location perform their work. However, for those concerns whose “primary industry” (see 13 CFR 121.107) is service or construction (see 13 CFR 121.201), the determination of principal office excludes the concern's employees who perform the majority of their work at job-site locations to fulfill specific contract obligations.
Employee means all individuals employed on a full-time, part-time, or other basis, so long as that individual works a minimum of 40 hours per month. This includes employees obtained from a temporary employee agency, leasing concern, or through a union agreement or co-employed pursuant to a professional employer organization agreement.
