  1. Indiana Plumbing Commission — Plumbing Contractor License

    Indiana has no 'Master Plumber' license. Anyone contracting plumbing work must hold a Plumbing Contractor license from the Indiana Plumbing Commission (Indiana Professional Licensing Agency). Qualify via four years in a Commission-approved apprenticeship school, four years working under a licensed plumbing contractor, or an equivalent out-of-state license with four years' experience, then pass the PROV-administered exam. Applicants must be at least 18.

  2. No General Business License in Evansville

    Evansville does not require a general/universal business license for most business types. The City Controller's office issues licenses only for specific activities (e.g., street vending, hotels, pawnbrokers, secondhand dealers) — none apply to a typical service business. Verify zoning compliance and, if applicable, a Certificate of Occupancy with the Area Plan Commission / Building Commission before opening.
