A township board may license persons or entities engaged in the business of providing adult entertainment within the boundaries of the township but outside the limits of cities, villages, and incorporated towns. The board shall fix the amount, terms, and manner of issuing and revoking licenses, except that license fees for the privilege of engaging in the business of providing adult entertainment may not exceed $300 per year. The operation of an adult entertainment business without a license is a separate petty offense for each day of violation. For purposes of this Section, “adult entertainment” means commercial production, presentation, sale, dissemination, or distribution of material that, when considered as a whole, appeals predominantly to interest in nudity or sex.
