If you are already licensed, they cannot "re-license" you.
They must register you.
There's a village near me that wants to hit up all contractors with a $50 fee:
All businesses as defined by the Village of Wilmette’s Ordinance No. 94-0-5 may not operate without a valid general business license issued by the Village of Wilmette. This includes the following businesses performing services in Wilmette regardless of the location of the business: any contractors performing an activity requiring a Building, Plumbing, Electrical, Demolition, or Excavation permit.
Also included are Landscapers, Pesticide Sprayers, Lawn Fertilizers, Weed Sprayers, and Garbage or Refuse Haulers.
I'm supposed to bid on a job down there... think I might bring an excerpt from the ILCS ;D
