Quiet hours in Concord, CA — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Concord enforces nighttime quiet hours between 10 PM and 7 AM on weekdays and Saturdays, and until 8 AM on Sundays and holidays. During these hours, amplified sound, loud gatherings, power equipment, and other disturbances are prohibited in residential areas. Violations can result in warnings, administrative citations, and misdemeanor charges for repeat offenses.
Concord's quiet hours are established in Municipal Code Chapter 82 Article V and are reinforced by the city's noise element and construction permit conditions. The standard residential quiet period runs from 10:00 PM to 7:00 AM Monday through Saturday, with an extended weekend start of 8:00 AM on Sundays and federal holidays. During these hours, the nighttime exterior noise limit drops to approximately 50 dBA at any residential property line, and the general prohibition on loud, disturbing, or unnecessary noise is more strictly applied. Typical violations include loud parties, amplified music, barking dogs, and operation of mechanical equipment. Concord Police respond to acute disturbances and may issue warnings, administrative citations, or misdemeanor citations depending on the nature and frequency of the violation. Hosts of loud parties can be held financially responsible for police response costs under the city's loud/unruly gathering provisions. Code Enforcement handles chronic violators through escalating enforcement. Concord's quiet hours are consistent with most Bay Area municipalities and align with BAAQMD regional practices.
