Overview of City Business Licenses

Most city business licenses in New Haven are administered by the City Clerk or by department-specific programs (for example, Environmental Health for food services and Building for construction-related permits). To find ordinance authority and local definitions, consult the New Haven municipal code on licensed activities and permits: Municipal Code - Licenses & Permits[2]. For application processing and general licensing inquiries, the City Clerk's licensing pages list permit types and contacts: City Clerk - Licensing[1].

Always confirm required permits early in your planning process.
