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

Pomona Municipal Code Section 18-196 addresses noise disturbances as part of the city's general nuisance and public welfare provisions under Article VI. The ordinance designates nighttime quiet hours from 10:00 PM to 7:00 AM on weekdays and from 10:00 PM to 8:00 AM on weekends and recognized holidays. During these hours, any sound that is audible beyond the property boundary of its source and disturbs the comfort, repose, health, or peace of persons of normal sensibilities is a violation. This standard applies to all sound sources including amplified music, voices, gatherings, vehicle engines, barking dogs, and mechanical equipment.

Outside of quiet hours, Pomona employs a general nuisance standard that prohibits willfully making or continuing any loud, unnecessary, or unusual noise that disturbs the peace or quiet of any neighborhood. Enforcement during daytime hours requires a higher threshold of disruption, typically sustained or repeated noise that interferes with normal residential activity. The distinction is important for Pomona's densely populated neighborhoods near Cal Poly Pomona, where student gatherings and late-night social activity generate a significant volume of complaints. The Pomona Police Department patrols these areas and responds to noise complaints, particularly on weekend evenings.

For ongoing property-related noise issues such as persistently barking dogs, malfunctioning alarms, or commercial equipment operating during quiet hours, the Pomona Code Enforcement Division handles investigations. Residents are encouraged to document the frequency and duration of disturbances before filing a formal complaint. The City also operates a mediation program through the Inland Valley Justice Center to help neighbors resolve noise disputes before they escalate to citations.
