2. City of Meridian — No General Business License

   Meridian does not require a general business license, and there is no annual renewal or display requirement. A new business moving into a commercial space typically needs a Certificate of Zoning Compliance and a Certificate of Occupancy from Community Development before opening. Only specific activities need a license or permit from the City Clerk's Office: alcohol licenses and catering permits, mobile sales units, temporary use permits, vehicle immobilization, fireworks, pawnbroker and precious metal dealer licenses, and dog licensing. Most businesses need none of these.
