Outdoor Music: Chino vs Ontario
How do outdoor music rules compare between Chino, CA and Ontario, CA?
Chino and Ontario have similar restriction levels.
Chino, CA
San Bernardino County
Amplified outdoor music in Chino is regulated by Chino Municipal Code Chapter 9.40 (NOISE) plus the City's special-event permitting process. Amplified sound that exceeds the §9.40.040 exterior noise standards (65 dBA daytime / 55 dBA nighttime at the nearest residential property line) is a violation unless covered by an exemption — most commonly a city-permitted special event, parade, or authorized public-park activity. Routine amplified music from a backyard party, restaurant patio, or event venue must comply with the standard. Chino updated its loud-party ordinance in 2019 to impose a flat-rate fine schedule for noise nuisance / disturbing-the-peace responses; subsequent responses to the same address within a defined period trigger escalating cost-recovery charges and may be assessed against the property owner.

Chino FAQ
Can I have a backyard wedding with a DJ in Chino?
A one-time private residential event with amplified sound is generally allowed if it ends before 10 p.m. and stays under 65 dBA at the nearest neighboring property line. For louder or later events, request a special event permit and notify neighbors in advance — this builds a record of good faith if a noise complaint arrives. After 10 p.m., the 55 dBA nighttime limit applies and a sub-bass-heavy DJ setup will typically exceed it at the property line.
Does my restaurant patio need a separate permit for a live acoustic band?
Yes if your CUP doesn't already include an entertainment provision. Check your conditions of approval — many older Chino CUPs are silent on entertainment, in which case amplified or live music is a new use requiring a CUP amendment. Even with a CUP, the §9.40.040 standard still applies at the nearest residential property line.
Ontario FAQ
Do I need a permit for outdoor music at a wedding?
Most venues carry the permit. For private property outdoor events with amplified music, check with Ontario's special-event office and plan to end amplified sound by 10 PM.
Can a restaurant have a live band on the patio?
Yes if the conditional-use permit and entertainment license allow it. The business must stay within noise limits and meet any curfew conditions set by the city.
