Full Breakdown
The Town of Castle Rock regulates noise directly under Municipal Code Chapter 9.16 (Noise Control), section 9.16.030 Prohibited Acts. As a Colorado home-rule town, Castle Rock sets its own thresholds and does not defer to the county. The Town's published standard is that radios, televisions, musical instruments and similar devices may not be audible 100 feet away, nor audible through walls common to two parties. Construction hours of operation are 7 a.m. to 7 p.m., meaning quiet hours run 7 p.m. to 7 a.m. Colorado's state maximum-permissible-noise statute (CRS 25-12-103) backs this up, treating residential noise above 55 dB(A) daytime / 50 dB(A) nighttime measured 25 feet from the property line as prima facie public nuisance.
