Pomona Outdoor Music Rules Rules (2026): What You Need to Know

Pomona Municipal Code Section 18-196 addresses amplified sound through its general noise disturbance provisions. During quiet hours — 10:00 PM to 7:00 AM on weekdays and 10:00 PM to 8:00 AM on weekends — amplified music, public address systems, and sound-reproducing devices that are audible at or beyond the property line of the source property constitute a per se violation. During daytime hours, these devices must not cause the noise level at adjacent residential property lines to exceed the applicable zone standard of 55 dBA.

Sound trucks and mobile amplification systems require a permit from the City and may operate only between 9:00 AM and 9:00 PM on weekdays. They are prohibited within 200 feet of schools, hospitals, churches, and senior care facilities. For organized outdoor events with amplified music — concerts, festivals, community celebrations — a Special Event Permit must be obtained through the Pomona Planning Division. The permit application requires a sound management plan, including speaker orientation, maximum decibel levels at the property boundary, and a designated sound monitor.

Pomona's proximity to the LA County Fairplex creates a unique dynamic. The Fairplex hosts numerous events throughout the year, including the LA County Fair, concerts, and car shows, many of which involve substantial amplified sound. The Fairplex operates under a separate agreement with LA County, but Pomona's noise standards still apply at the Fairplex property boundary where it abuts residential neighborhoods. Residents in the neighborhoods along McKinley Avenue and Fairplex Drive may contact both the Fairplex administration and Pomona Police if event noise exceeds acceptable levels.
