Colorado statute CRS 25-12-103 caps noise at a property line by zone: 55/50 dB(A) residential, 60/55 commercial, 70/65 light industrial, and 80/75 industrial (day/night). Jefferson County mirrors these limits.
The state noise statute sets prima-facie public-nuisance thresholds measured 25 feet or more from a property line, split by day (7 a.m.-7 p.m.) and night (7 p.m.-7 a.m.). Jefferson County's Noise Abatement Policy adopts the same residential figures and adds construction and vehicle standards. Daytime levels may be exceeded by 10 dB(A) for up to 15 minutes each hour. Periodic, impulsive, or shrill noise becomes a nuisance at 5 dB(A) below the listed caps. Measurements require wind under 5 mph.
Under state law, exceeding limits is prima facie a public nuisance abatable in district court. County citations are a Class 2 Petty Offense ($30-$300).
