Short-term rentals are prohibited citywide in Costa Mesa, so no STR-specific noise rules exist. The general noise control ordinance in CMMC Chapter XIII applies to all residential properties including those where illegal STR activity is suspected.
Since Costa Mesa prohibits all short-term rentals under Ordinance 2021-17, there are no STR-specific noise regulations. Common complaints about illegal STR operations include noise disturbances from guests, parties, and late-night activity. Any residential property is subject to the city's general noise control provisions in CMMC Chapter XIII regardless of rental status. Section 13-280 establishes exterior noise standards and Section 13-281 establishes interior noise standards. Residents who suspect illegal STR activity accompanied by noise disturbances should report both the illegal rental and the noise violation. Contact the Costa Mesa Police Department at (714) 754-5252 for immediate disturbances or Code Enforcement for ongoing issues.
Illegal STR operators face fines up to $1,000 per day. Noise violations from any property are separately enforceable under CMMC Chapter XIII with additional fines.
