Menifee, CA
Riverside County
Menifee has no standalone amplified-sound permit chapter. Amplified music — backyard speakers, DJ events, car audio, business sound systems — is regulated through MMC Chapter 11.07 "Unruly or Loud Conduct," which makes it unlawful and a public nuisance to engage in (or host a gathering involving) loud conduct that disturbs the peace. The General Plan Noise Element uses 65 dBA CNEL as the exterior residential threshold; construction-related amplified equipment must also respect MMC § 8.01.010 construction hours. State law (Vehicle Code § 27007) separately limits vehicle amplified sound audible at 50 feet.

Menifee FAQ
Can I play amplified music in my backyard?
Yes, but volume that disturbs neighbors can be cited as a public nuisance under MMC § 11.07.020. The General Plan Noise Element treats 65 dBA CNEL as the exterior residential threshold; sound that crosses property lines well above ambient levels is the typical trigger for enforcement.
Do I need a permit for an outdoor amplified event?
Larger amplified events at commercial sites or public venues typically require a Temporary Use Permit through the Menifee Title 9 Development Code, with hour and decibel conditions tied to the General Plan Noise Element standards.
What about loud car stereos?
Cal. Vehicle Code § 27007 prohibits amplified sound from a motor vehicle on the highway that is audible 50 feet or more from the vehicle. Menifee Police enforce this as a state-law infraction.
Riverside FAQ
Can my backyard speakers play at any volume during the day?
No. Under the 2025 amendment to RMC § 7.35.010(D), if your amplified music is plainly audible 25 feet or more beyond your property line, it is a violation regardless of the time of day.
What changed in 2025?
City Council amended § 7.35.010 to add subsection (D), which extends the prohibition on plainly-audible amplified sound to all hours, not just the previous 10 p.m.-7 a.m. window. § 7.15.010 fines were also reaffirmed at $500/$750/$1,000.
Are concerts and school events exempt?
Yes - § 7.35.020(B) exempts authorized school bands, school athletic and entertainment events, and occasional public/private gatherings between 7 a.m. and 10 p.m. A variance under § 7.40.010 is required to run later.
