Full Breakdown
040(D)(1) sets the City's core nighttime bright-line test. 040(A), which bars any "disturbing, excessive, offensive, or unreasonable noise" that disturbs the health, safety, welfare or quiet enjoyment of others. Because the 50-foot audibility test is prima facie evidence, officers don't need a sound meter reading to write a citation during curfew hours, audibility alone establishes the violation. 040(B): intensity, whether the noise is usual or unusual, proximity to sleeping facilities, time of day, duration and whether it's recurrent. 050(B).
Violations & Fines
A first violation is enforceable as a misdemeanor or infraction under general Municipal Code penalty provisions. A second violation at the same property within 365 days exposes the responsible person, including a landlord with actual notice of a tenant's first violation, to an administrative fine of $1,000 per incident under CVMC 17.24.060(A), plus liability for the City's police-response costs under 17.24.060(C).
