Mesa County, CO Noise Ordinances: Amplified Music & Outdoor Sound (2026)

Mesa County's Land Development Code sets a specific decibel ceiling for outdoor amplified music tied to its Agritourism accessory-use category, LDC Section 12.07.A.5.b(1). The limit is 65 decibels from 7:00 a.m. to 10:00 p.m. and 60 decibels from 10:00 p.m. to 7:00 a.m., "as measured at or beyond any of the property lines from which the noise is emanating," so enforcement is based on what a neighbor experiences at the boundary line rather than at the source.

This standard applies to accessory agritourism activities such as U-pick operations, farm stands, hayrides and the outdoor events and experiential lodging described in the same section, capped at 25 to 205 attendees depending on acreage and four events per month, not to exceed 24 per year. If an agricultural operation wants a bigger, louder gathering than the agritourism thresholds allow, the event is reclassified as a Minor Entertainment Event under LDC Section 6.02.Z, which requires a Conditional Use Permit application that must separately address "Noise limits set forth in C.R.S. §25-12-103," along with hours of operation, screening and distance from neighboring residences.

The two-tier structure means small farm events stay under the flat 65/60 decibel rule, while larger, ticketed festivals or concerts on agricultural land face a discretionary county review that folds in the state noise statute. Mesa County Community Development is the reviewing agency for the underlying land use permit, though a decibel complaint about an ongoing event would typically go to Code Compliance Services or the Sheriff's Office for a noise-disturbance response.
