Showing ordinances that apply to East Richmond Heights, CA
East Richmond Heights is an unincorporated community (population 3,460) in Contra Costa County, California. Because East Richmond Heights is not an incorporated city, it does not have its own municipal code. Instead, Contra Costa County ordinances apply directly to properties here. The quiet hours rules below are the ones that govern your area.
Unincorporated Contra Costa County generally observes quiet hours from 10:00 PM to 7:00 AM, during which loud residential noise (parties, amplified music, power equipment) is prohibited. The county relies on the reasonable-person standard in Title 716 rather than a fixed nighttime decibel cap.
Quiet hours in unincorporated Contra Costa County run from 10:00 PM to 7:00 AM on weekdays, typically extended to 8:00 AM on weekends and holidays. During these hours, any noise plainly audible inside a neighboring dwelling with doors and windows closed is presumed unreasonable under the nuisance standard of the County Ordinance Code. Common violations include late-night parties, outdoor amplified music, barking dogs, and early-morning landscaping equipment. The Sheriff's Office responds to nighttime noise complaints in areas such as Alamo, Blackhawk, Discovery Bay, Bay Point, Kensington, and El Sobrante. A first response is usually a warning. A second call within a short window can result in an administrative citation. California has no statewide quiet-hours law, so the county's local rule prevails. HOAs in master-planned communities like Blackhawk and Rossmoor-adjacent areas often impose stricter quiet-hour rules that the county does not enforce but are privately enforceable by the association.
