  1. City of Boise — No General Business License

    Boise does not require a general/blanket business license. Businesses must instead comply with zoning, required building/health permits, and any applicable activity-specific city license (Animal, Food & Alcohol Beverage, Security Services, Vehicle Licensing). Most professional/personal-service businesses fall under none of these categories and need no city business license — verify your specific business's obligations with the City Clerk's Licensing page.
