Summary
El Monte caps property-line noise by zone under Municipal Code Chapter 8.36: 50 dBA day and 45 dBA night at single-family homes, 65/60 commercial, and 70 dBA in industrial zones. A data center's fixed cooling and generator noise cannot exceed these ambient limits by more than 5 dBA.
It is unlawful for any person to create any noise which would cause the noise level at the property line of any property to exceed the ambient noise level by more than five (5) decibels for a cumulation period of fifteen (15) minutes in any hour.
Full Breakdown
El Monte's noise ordinance, Municipal Code Section 8.36.040, sets ambient noise standards at the property line by zoning district: single-family residential 50 dBA (7 a.m.-10 p.m.) and 45 dBA (10 p.m.-7 a.m.); multifamily 55/50; commercial 65/60; and industrial 70 dBA day and night. It is unlawful to raise the noise level at any property line more than 5 dBA above the ambient limit for 15 cumulative minutes in an hour. At a residential-manufacturing boundary the residential limit governs, and a residence inside an industrial zone is protected at 50 dBA overnight. The code's "fixed noise source" definition expressly covers generators, compressors, fans, air conditioners, and refrigeration equipment - a data center's cooling and backup power.
Violations & Fines
Noise over the Section 8.36.040 limits is a misdemeanor punishable by a fine up to $500 or six months in jail, and each day is a separate offense; the city can also abate it as a public nuisance.
