Amplified music rules in Denver, CO — also called sound permit, PA system, or live music ordinances — set decibel limits, time-of-day restrictions, and when permits are required.
Denver regulates amplified sound under DRMC Chapter 36 with specific decibel limits and requires a Sound Amplification Permit from the Department of Excise and Licenses for outdoor events, concerts, and festivals. Residential amplified music must stay below 55 dB(A) at the property line during the day.
Denver's Noise Ordinance (DRMC §§36-1 through 36-19) establishes maximum permissible sound levels by zone and time. Residential zones allow 55 dB(A) from 7 AM to 10 PM and 50 dB(A) overnight; commercial and mixed-use zones allow 60 to 65 dB(A) daytime. For amplified public events, organizers must apply for a Sound Amplification Permit through Denver Excise and Licenses at least 30 days in advance, with fees starting around $75. Major outdoor venues (Red Rocks, Civic Center Park, Coors Field area) operate under venue-specific sound conditions. Residential amplified music audible beyond property lines or after 10 PM triggers DRMC §36-6 (disturbing the peace) enforcement. Colorado state law (CRS §18-9-106) also covers unreasonable noise as a class 1 petty offense. Denver Police respond to amplified noise complaints and may cite hosts, DJs, or venue operators. Complaints can also be filed via Denver 311 for code enforcement follow-up.
DRMC §36-6 noise violation: $150 to $999 and/or up to 300 days jail. Unpermitted public amplified event: $500+ plus cease-and-desist. CRS §18-9-106 (disturbing the peace): class 1 petty offense up to $500.
