  1. City of Green Bay Office of the City Clerk — Business License

    Green Bay does not require a general/all-purpose business license. The City Clerk's office (Green Bay Municipal Code Ch. 10) licenses only specific regulated categories (e.g. Adult Entertainment, Alarm Business, Direct Seller/Solicitor, Entertainment Facility, Home-Based Businesses, Junk Collector, Massage Establishments, Mobile Food Vendor, Public Vehicle, Salvage, Secondhand Dealer, Tree & Brush Trimmer). Most business types listed here (barber shop, yoga studio, home bakery, daycare, handyman, cleaning service, photography, auto repair, electrical contractor, tutoring, nail salon, tattoo parlor, pet sitting, catering, personal trainer, hair salon, landscaping, plumbing) do NOT require a general city business license. Massage-therapy businesses need a specific Massage Establishment License, mobile-dog-grooming/pet-sitting need an Animal Establishment License, and food trucks need a Mobile Food Vendor License — each covered separately. Confirm with the City Clerk if unsure.
