Summary
El Monte treats loudspeakers and sound-amplifying equipment as a 'special noise source' under Municipal Code Section 8.36.050(D): amplified sound that exceeds the ambient noise limit at a neighboring property line is a violation, no matter what time of day it runs. The rule applies on top of, not instead of, the base decibel limits set for each zoning district.
D. Amplified Sound. The use of loudspeakers or sound amplifying equipment in the city which exceeds the noise limits at any property line of a receiving property shall be a violation of Section 8.36.040(A).
Full Breakdown
Section 8.36.050(D) singles out loudspeakers and sound-amplifying equipment as a special noise source: any use of such equipment in the city that exceeds the noise limits at any property line of a receiving property is a violation of Section 8.36.040(A), the chapter's underlying ambient noise standards. Those standards cap noise at 50 dBA in single-family zones and 55 dBA in multifamily zones during the day (7 a.m. to 10 p.m.), dropping to 45 dBA and 50 dBA respectively at night (10 p.m. to 7 a.m.), with higher ceilings of 65/60 dBA for commercial zones and a flat 70 dBA for industrial zones.
Because amplified sound is measured the same way as any other noise source, exceeding those property-line limits with a PA system, outdoor speakers, or a DJ setup is enough to trigger a violation, regardless of whether the event is a private party or a commercial promotion. The same chapter separately makes hosting a private or public dance, party, gathering, or event in a residential neighborhood unlawful if the resulting sound constitutes a noise disturbance, under Section 8.36.080, and repeated large gatherings that draw a police response can expose the person in charge of the premises to civil liability for abatement costs of up to $1,000 under Section 8.36.100.
Measurements are taken with an A-weighted sound level meter on slow response under Section 8.36.030, from any point on the affected residential property, per Section 8.36.060.
Violations & Fines
A first amplified-sound violation is a misdemeanor under Section 8.36.110, punishable by up to $500 in fines, up to six months in county jail, or both, with each day of continued violation a separate offense. Police can also summarily abate the noise disturbance under Section 8.36.090, and a large gathering that draws an emergency response can trigger civil liability for the city's response costs, capped at $1,000.
