Outdoor live or recorded music is limited by the same residential caps: 55 dB(A) (day) and 50 dB(A) (night) at 25 feet from a property line. Non-profit and government cultural events are exempt.
Under the Noise Abatement Policy, any outdoor activity making sound above the permissive levels is prohibited, so backyard concerts, patio speakers, and live bands must meet the 55/50 dB(A) residential thresholds. State statute CRS 25-12-103(11) and the county policy exempt cultural, entertainment, athletic, or patriotic events held by the state, a political subdivision, or non-profits, including concerts and music festivals. A daytime 10 dB(A) allowance for up to 15 minutes per hour also applies to ordinary sources.
Class 2 Petty Offense; $30 per offense up to a $300 maximum, plus court costs, unless the event qualifies for the cultural-event exemption.
