The Short Version
Mission Viejo Municipal Code Chapter 9.02 establishes quiet hours during which noise that disturbs the peace and comfort of residential neighborhoods is prohibited. Nighttime quiet hours run from 10 PM to 7 AM daily. During these hours, any noise that is audible beyond the property line and disturbs or could disturb a person of normal sensitivity is unlawful. The ordinance covers amplified music, loud gatherings, barking dogs, mechanical equipment, and other sources of unreasonable noise. Mission Viejo is a master-planned community of approximately 95,000 residents in south Orange County. The city's residential character — with extensive HOA-governed neighborhoods developed primarily in the 1970s and 1980s — means that noise complaints are taken seriously by both the city and individual homeowners associations. While the municipal code provides the baseline legal framework, many HOAs in Mission Viejo impose additional quiet-hours restrictions that may be more stringent than the city ordinance. Residents may report noise complaints to the Orange County Sheriff's Department, which provides contract law enforcement services to Mission Viejo, at the non-emergency line (949) 770-6011. For chronic or property-related noise issues, Code Enforcement can be contacted through the city's Community Development Department at (949) 470-3056.

What Happens If You Violate This?
Quiet-hours violations are infractions punishable by fines of $100 for a first offense, $200 for a second offense within one year, and up to $500 for subsequent offenses within one year. Chronic noise disturbances that constitute a public nuisance may be prosecuted as misdemeanors, carrying fines up to $1,000 and/or up to six months in county jail. The city may also pursue administrative abatement proceedings for properties with persistent violations. HOA enforcement is separate and may include fines, hearing notices, and potential lien authority under the association's CC&Rs. Residents may face both city and HOA penalties for the same noise event.
