Secondhand Smoke Regulations & Responsibilities

Secondhand Smoke Regulations & Responsibilities

Our state and local communities have worked together to pass comprehensive smoking ordinances. In 2006, the Colorado Clean Indoor Air Act (CCIAA) was passed, making most indoor places in Colorado smoke-free. The law intends to protect all Coloradans by reducing their exposure to secondhand smoke. There is no safe level of exposure to secondhand smoke.

Most Public Places Are Smoke-Free

Under the Colorado Clean Indoor Air Act (CCIAA), nearly all indoor places are smoke-free, including restaurants, bars, libraries, theaters, common areas, and many other community locations. A building’s main entryway must also be smoke-free, and smoking should not take place within 15 feet of that entryway.


Private homes, cigar bars, tobacco retailers, limos under private hire, and a certain number of hotel or motel rooms are among the few exceptions to the law.

Local Regulations

Boulder County municipalities may have enacted stricter regulations regarding smoking, so be sure to check your municipal code. Property owners and managers are also allowed to implement stricter code under the CCIAA. Many places have already begun to implement more smoke-free protections on their properties.
