Summary
El Monte bars noisy handling of boxes, crates, containers, or building materials in residential zones between 10 p.m. and 7 a.m. Municipal Code Section 8.36.050(E) targets loading and unloading noise specifically, layered on top of the chapter's night-time ambient limit, which drops to 45 dBA in single-family zones and 50 dBA in multifamily zones after 10 p.m.
E. Loading/Unloading. In residential zones, the opening, closing or other handling of boxes, crates, containers, building materials, or similar objects in such a manner as to cause a noise disturbance is not permitted between the hours of ten p.m. and seven a.m.
Full Breakdown
Section 8.36.050(E) makes it unlawful, in residential zones, to open, close, or otherwise handle boxes, crates, containers, building materials, or similar objects in a manner that causes a noise disturbance between 10:00 p.m. and 7:00 a.m. The provision is aimed squarely at loading-dock and delivery-truck noise near homes, on top of the chapter's general night-time ambient ceiling, which under Section 8.36.040(A) drops to 45 dBA in single-family zones and 50 dBA in multifamily zones between 10 p.m. and 7 a.m., compared to 50 dBA and 55 dBA during the day.
A related nighttime curfew covers residential properties within 150 feet of a freeway: Section 8.36.050(H) sets a permissible standard of 62 dBA between 7 a.m. and 10 p.m. and 58 dBA between 10 p.m. and 7 a.m. for those parcels specifically. Interior noise inside a condominium, duplex, or multifamily unit is capped at the same Section 8.36.040(A) limits around the clock under Section 8.36.050(F), so a neighbor's late-night television or stereo can also be cited. Construction noise has its own separate nighttime curfew: power construction tools and equipment on outside building or repair work near a residential area are barred outside 6 a.m. to 7 p.m.
Monday through Friday and 8 a.m. to 7 p.m. on weekends under Section 8.36.050(C), though the Chief Building Official can grant a written variance from those hours for good cause.
Violations & Fines
A loading or unloading noise violation between 10 p.m. and 7 a.m. is enforced as a misdemeanor under Section 8.36.110, punishable by up to $500 in fines, up to six months in jail, or both, with each day a separate offense. Police may also summarily abate the disturbance under Section 8.36.090, and the case can proceed even if the violator can't be located, by mailing notice to their last known address.
