Summary
Food and merchandise vendors at a Naperville street fair or festival must operate under the event's special event permit, hold county health department approval if selling food, and pay the city's food and beverage tax. Naperville police, fire and public works staff inspect vendor booths during the event, and any vendor found out of compliance can be barred from continuing to sell.
3-4C-5: Food and beverages may be sold at a special event if approved and licensed as necessary by the appropriate county health department. All vendors participating in a special event shall comply with the payment requirements of the City's food and beverage ordinance as amended from time to time. 3-4C-7: Individual vendors may only participate if it is determined that they are in compliance with applicable State law and City Code provisions. The City may inspect the event premises and participating vendors at any time during the event to ensure continued compliance with City Code, State law and specific permit conditions, if applicable.

Full Breakdown
75%) Downtown Food and Beverage Tax on sales inside the downtown boundary. The special event permit itself, obtained through the City Clerk's Office at least one hundred twenty (120) days before the event under § 3-4C-3, consolidates the licenses a street fair or festival vendor otherwise needs, including temporary signage, tents and right-of-way use, so a vendor booth does not need a separate permit for each item once the umbrella special event permit is issued. Compliance does not end at issuance: § 3-4C-7 puts the Fire Department, Police Department, Department of Public Works and the Transportation, Engineering and Development Business Group on notice of every proposed event, and states plainly that individual vendors may only participate if it is determined that they are in compliance with applicable State law and City Code provisions.
The same section authorizes the city to inspect the event premises and participating vendors at any time during the event to ensure continued compliance with City Code, State law and specific permit conditions. Event organizers must also carry insurance naming the city as an additional insured, and full-contact martial arts or carnival-style attractions trigger extra conditions under § 3-4C-6, but a straightforward food or merchandise vendor booth at a neighborhood festival is governed by the health-license, tax and inspection rules above.
Violations & Fines
Naperville has no separate fine schedule for special event vendor violations, so the citywide default in § 1-4-1 applies: a fine of not less than one hundred dollars ($100.00) nor more than five hundred dollars ($500.00) for each offense, with each day a violation continues counted as a separate offense. Under § 3-4C-7, city inspectors can pull a noncompliant vendor from the event on the spot, and under § 3-4C-4 the city bills the event organizer, not the vendor, for any City service costs the violation triggers.
