It shall be unlawful for any person to conduct, engage in, maintain, operate, carry on, or manage any business, either by himself or itself, or through an agent, employee, or partner, without first having obtained a license for such business.  A license is required when any person, by himself or through an agent, employee, or partner, is held forth as being engaged in the business, or if he solicits patronage therefor, actively or passively, or if he performs or attempts to perform any part of such business in the City.

    If any business falls into more than one of the categories requiring a license under this chapter, a separate license shall be obtained for each category.

    A license shall not be required for any amusement, entertainment or exhibition given by residents or the City who are not engaged therein as a business for personal profit or gain and the proceeds of which are exclusively for the benefit of a charitable organization registered with the Illinois Attorney General pursuant to the Solicitation for Charity Act (225 ILCS 460/01.01, et seq.).
