Fontana FAQ
Can I have a backyard party with speakers?
Yes during daytime hours. Keep sound from being plainly audible at neighboring property lines, and shut amplification off by 10 PM.
What about car stereos?
Audible at 50 feet from the vehicle is the traditional California standard. Fontana Police enforce both under state Vehicle Code and local nuisance rules.
Hesperia FAQ
Do I need a permit for a backyard party with a DJ in Hesperia?
For a normal private party, no — but the music must stop being audible at the property line by 10 PM and must not be a recurring nuisance. Larger events (50+ guests, ticketed, advertised) need a Temporary Use Permit from Planning under Title 16 Ch. 16.12.

Hesperia treats 10 PM as the nighttime nuisance threshold. After 10 PM, amplified music audible at a neighbor's property line is a Sheriff-and-Code-Enforcement matter.
Is loud car audio enforceable?
Yes — under California Vehicle Code §27007, sound audible more than 50 feet from a vehicle is an infraction, citable by the San Bernardino County Sheriff.
