CO SB171

Entertainment facilities with 7,000+ seats must designate and enforce at least 4% of seating capacity as substance-free areas where alcohol, electronic smoking devices, marijuana, and tobacco are prohibited, effective January 1, 2026.

Substance-free seating cannot be limited exclusively to seats with poor views and must include accessible seating for persons with disabilities; facilities must adopt written policies, enforce the ban, and display prominent signage.

Tickets for substance-free seating must be conspicuously marked and incorporate the facility's policies as terms and conditions of purchase and resale.

Failure to comply with substance-free seating requirements constitutes "good cause" for state and local licensing authorities to refuse, deny, suspend, or revoke alcohol beverage licenses, or impose fines.

Local authorities may impose more stringent substance-free seating requirements than the 4% minimum; the act takes effect after a 90-day period following legislative adjournment unless subject to referendum.
