The Smoke-free Illinois Act (SFIA), is an Illinois law that protects the public from the harmful effects of exposure to tobacco smoke and e-cigarette vapor. SFIA prohibits smoking of all forms of combustible tobacco, including cigarettes, cigars, hookah, and e-cigarettes, vapes, and any other electronic smoking device in public places, places of employment, and within 15 feet of any entrance, exit, windows that open, or ventilation intake of a public place or place of employment.

The act also includes requirements for signage and describes how to file a complaint, the enforcement process, and how fines will be determined for violations. Local ordinances may have additional regulations on where smoking is prohibited.


Under the Smoke-free Illinois Act, businesses must:

  • Not permit smoking at your business or within 15 feet of all entrances, exits, windows that open, and ventilation intakes.
  • Remove ashtrays from areas where smoking is prohibited.
  • Ensure smoking areas are at least 15 feet from outdoor patio areas.
  • Post “No Smoking or E-” signs at each entrance to the place of employment or public place  to notify patrons and employees that smoking, including e-cigarette use is prohibited.
    • “No Smoking or E-Cigarette Use” signs must comply with the specification in the Smoke-free Illinois Act and be clearly posted at each entrance of public places and place of employments where smoking is prohibited.
  • Business and individuals found in violation of the Smoke-free Illinois Act are subject to fines
