St. Louis County Indoor Clean Air Act Code aka "Smoking Ban"

Indoor Clean Air Code | St. Louis County

The St. Louis County Council has passed and the voters of St. Louis County have approved the “Indoor Clean Air Code” (Chapter 605), which has been in effect as of January 2, 2011.

The “Indoor Clean Air Code” allows smoking in drinking establishments with a valid liquor license that have applied for and met the qualifications for exemption.

St. Louis County Ordinance 605.030 defines the term “Drinking Establishment” as follows:

Any business with a valid license issued by the St. Louis County Department of Revenue (pursuant to Chapter 801, Title VIII SLCRO 1974 as amended, "Alcoholic Beverages") to sell intoxicating liquor by the drink or to sell beer and light wine by the drink whose on-site sales of food for consumption on the premises comprises no more than 25% of gross sales of food and both alcoholic and non-alcoholic beverages on an annual basis.

Application Requirements:

The application must state the correct legal name of the owner, i.e., Sole Ownership, Partnership, or a Corporation, the DBA if applicable, address of business, phone number(s), email address, years of operation, and the St. Louis County liquor license number.

Also required is the prior year’s fiscal report of food and beverage sales percentage, including a break-out of the food sales percentage.

Instructions for completing the financial information are located on the reverse side (page 2 of the online application) of the Smoking Exemption Application. The application must be signed, notarized, and accompanied by the application fee in the amount of $35.00.

Following the filing of the application, an investigation will be conducted to determine if all requirements as set forth in Chapter 605 are satisfied. Upon approval of the application, the St. Louis County smoking exemption certificate will be issued.


If your establishment is located in a municipality that has a smoking law or ordinances in effect, DO NOT COMPLETE an application for St. Louis County’s smoking exemption. The local smoking law takes precedence.
