Quiet hours in Richmond, CA — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Richmond's nighttime quiet hours run from 10:00 PM to 7:00 AM on weekdays and Saturdays, and until 8:00 AM on Sundays and holidays. During these hours, amplified sound, power tools, and loud activities audible at the property line are prohibited. Violations are enforced by Richmond Police and can result in infraction citations.
Under Richmond Municipal Code Chapter 9.52, nighttime quiet hours restrict sound that is audible from neighboring property. The standard residential quiet period is 10:00 PM to 7:00 AM Monday through Saturday, extending to 8:00 AM on Sundays and recognized holidays. During these hours, activities such as loud music, parties, power tool use, yard equipment, and commercial operations that produce audible sound beyond the property line can trigger enforcement. Officers may issue a warning on a first visit for a minor disturbance, but repeat calls to the same address within a short window typically result in an infraction citation and potential cost recovery for police response under Richmond's chronic nuisance framework. Commercial, industrial, and mixed-use properties adjacent to residential zones are held to the residential standard during quiet hours. Amplified outdoor events require a special event permit that specifies allowable hours, which may extend beyond standard quiet hours only with city approval.
