Riverside sets exterior noise limits of 55 dBA daytime and 45 dBA nighttime in residential zones, with graduated limits for commercial and industrial areas under RMC 7.35.
The Riverside noise ordinance establishes zone-based maximum exterior sound levels measured at the receiving property line: residential 55 dBA (7 AM - 10 PM) and 45 dBA (10 PM - 7 AM); commercial 65/60 dBA; industrial 70/65 dBA. These limits apply continuously; an additional rule prohibits any noise exceeding the limit by more than 5 dBA for 15 minutes per hour, 10 dBA for 5 minutes per hour, 15 dBA for 1 minute per hour, or 20 dBA at any time. Impulsive noises (hammering, pile drivers) are evaluated against lower thresholds. Measurements must be taken with a meter meeting ANSI S1.4 Type-2 standards. Riverside aligns with the statewide General Plan Noise Element requirements in Cal. Gov. Code 65302(f).
Confirmed excess triggers administrative citations ($100-$500); measurements can be compelled as evidence for code-enforcement and civil-nuisance proceedings.
