No municipality with a population of less than 1,000,000, including a home rule unit, may increase the fee for a license to own or operate a vending machine or to dispense goods or services therefrom unless notice of a public hearing on the matter has been given and such hearing has been held. The amount of the increase annually shall not exceed the greater of (i) $25, (ii) the amount of the fee multiplied by 5%, or (iii) the amount of the fee multiplied by the percentage increase in the Consumer Price Index for All Urban Consumers for all items published by the United States Department of Labor during the 12-month calendar year preceding the year in which the fee is increased. Notice of the proposed increase shall be mailed at least 30 days before the hearing to the last known address of each person currently holding such a license. It is declared to be the law of this State, pursuant to paragraph (g) of Section 6 of Article VII of the Illinois Constitution, that this Section is a denial of the power of certain home rule units to increase vending machine license fees without complying with the requirements of this Section.
