The Colorado Clean Air Act prohibits smoking in indoor public places and workplaces, including educational institutions and daycare facilities; healthcare facilities (including doctor's offices); restaurants, bars, private clubs, bowling alleys, gaming areas of casinos, and theatrical productions. Smoking is also prohibited on public transportation vehicles (CO Rev. Stat. Sec. 25-14-201et seq.).
The owner or manager of a facility where smoking is not prohibited under the Act may post the area as completely nonsmoking or limit smoking to specific designated areas.
Smoking is permitted in outdoor areas of businesses, but not within 15 feet of entryways.
Smoking is permitted in businesses with three or fewer employees not open to the public; however, an employer must provide a smoke-free area to employees who make this request.
Smoking is permitted in:
• Private homes, residences, and vehicles (except when used as part of a daycare facility);
• Designated residents' rooms in assisted living facilities
• Limousines and private cars for hire
• One-quarter of rooms in hotels and motels
• Retail tobacco businesses
• Cigar bars
• Designated smoking lounges at airports
• Nonresidential buildings on family farms and ranches with gross incomes under $500,000.
Local entities (counties, cities, and towns) may enact, adopt, and enforce smoking regulations that are more stringent than the Act, and many have done so. For example, they may extend the distance where smoking is permitted near entryways beyond 15 feet. A list of local ordinances in the state is available at http://www.gaspforair.org
