Amplified music rules in Littleton, CO — also called sound permit, PA system, or live music ordinances — set decibel limits, time-of-day restrictions, and when permits are required.
Arapahoe County regulates amplified music through the general noise ordinance and C.R.S. §18-9-106 disturbing the peace. Sound amplification permits are required for public events. Residential amplified music must not exceed property-line dB limits. Outdoor venues in unincorporated areas require special use permits.
Amplified music in Arapahoe County is regulated at two layers. The state floor is C.R.S. §25-12-103 (maximum permissible noise levels) and C.R.S. §18-9-106(1)(c) which makes unreasonable noise a Class 1 petty offense. In unincorporated Arapahoe County, the Sheriff's Office (County Sheriff John Kellner) handles enforcement of the county noise standards, which mirror the state dB schedule. Special events with amplified sound (concerts, festivals at venues like the Arapahoe County Fairgrounds) require a Special Event Permit from the county. In Aurora, City Code §94-90 governs sound amplification with permits issued through the Aurora Police Department for events exceeding standard noise limits. Centennial Municipal Code §7-1-70 and Littleton Municipal Code §6-4-9 follow similar frameworks. Home Rule cities can set stricter limits than the state floor. Outdoor concert venues like Fiddler's Green Amphitheatre (Greenwood Village) operate under conditional use permits with specific sound engineering conditions.
Noise violation without permit: $150 to $500 first offense in unincorporated county. Aurora disturbing the peace: up to $999 and 180 days jail (general penalty). Unpermitted event amplification: $500+ and event shutdown.
