Adams County uses Colorado's statewide decibel limits (CRS 25-12-103), measured 25 feet beyond the property line: Residential 55/50, Commercial 60/55, Light industrial 70/65, Industrial 80/75 dB(A) (day/night).
The Colorado Noise Abatement Act sets zone-based maximum permissible noise levels that the unincorporated county enforces. The day period is 7am to next 7pm; the night period is 7pm to next 7am. A daytime source may exceed its zone limit by up to 10 dB(A) for a single 15-minute period in any hour. Periodic, impulsive, or shrill noise is measured against limits 5 dB(A) below the listed values. Exceeding a limit at the 25-foot measuring point is prima facie evidence of a public nuisance.
Readings above the zone cap are prima facie evidence of a public nuisance under CRS 25-12-103, abatable through the Sheriff/code enforcement.
