Newport Beach Quiet Hours Rules (2026): What You Need to Know

NBMC Chapter 10.28 provides the primary noise control framework for the City of Newport Beach. The ordinance defines quiet hours as the period from 10 PM to 7 AM on weekdays (Monday through Friday) and 10 PM to 8 AM on weekends and city-recognized holidays. During quiet hours, it is unlawful to create, cause, or allow any noise that is audible beyond the boundaries of the property where it originates and that disturbs or could disturb a person of normal sensitivity residing in the vicinity. This standard applies equally to amplified music, live music, loud conversations, gatherings, barking dogs, swimming pool equipment, HVAC units, generators, and any other sound source.

Newport Beach's unique geography — encompassing a working harbor, the Balboa Peninsula, several islands, and hillside communities — means that sound can carry significant distances over water and through the canyon topography of Newport Coast. The Police Department receives a high volume of noise complaints during summer months, particularly on the Peninsula and Balboa Island where short-term rental guests, boating activity, and outdoor dining generate elevated noise levels. Officers responding to noise complaints will typically issue a verbal warning on the first contact and a citation on subsequent contacts within the same event.

The city also regulates noise from commercial establishments through conditional use permit conditions. Restaurants, bars, and entertainment venues operating in areas such as Cannery Village, Lido Village, and Mariner's Mile are often subject to specific noise conditions in their CUPs that may impose earlier quiet-hour cutoffs and lower decibel limits than the general residential standards. Chronic noise offenders, including problematic short-term rental properties, may be subject to enhanced enforcement including administrative citations and referral to the City Attorney.
