Full Breakdown

Section 9.08.050 lists two overlapping nighttime-quiet provisions. Subsection B, Radios, Stereos, Etc., bars playing or operating a radio, stereo or sound amplifying equipment in a manner that disturbs the peace, quiet and comfort of neighboring inhabitants, and it goes further for the night window: operating any such equipment between 8:00 p.m. and 7:00 a.m. in a manner audible to a property or structure adjacent to the building, structure or vehicle from which the sound comes shall be prima facie evidence of a violation of the section, meaning the city need not separately prove the sound was unreasonable once it clears that audibility and time threshold.

Subsection D, Yelling, Shouting, Etc., applies the identical prima facie structure to yelling, shouting, hooting, whistling or singing in a residential or commercial area between the same 8:00 p.m. and 7:00 a.m. hours. Both clauses sit inside the non-exclusive list of loud-or-raucous-noise acts declared unlawful by Section 9.08.020 and the policy statement in Section 9.08.010, which finds that loud or raucous noise is detrimental to public health, welfare and safety and constitutes a public nuisance that may be abated as such. Section 9.08.060 supplies the penalty: a misdemeanor or infraction at the prosecuting authority's discretion, each violation a separate offense, a service fee for repeated calls to the same address within 24 hours, and nuisance abatement under Chapter 8.16 for chronic offenders.

Violations & Fines

A radio, stereo or voice disturbance audible next door between 8:00 p.m. and 7:00 a.m. is prima facie evidence of a violation under Section 9.08.050(B) or (D), punishable as a misdemeanor or infraction under Section 9.08.060(A) at the prosecuting authority's discretion. Repeated police calls to the same address within 24 hours add a service fee, and chronic disturbances can be abated as a public nuisance.

Frequently Asked Questions

What counts as a nighttime noise violation in Montebello?
Section 9.08.050(B) makes it prima facie evidence of a violation if a radio, stereo or sound amplifying equipment is operated between 8:00 p.m. and 7:00 a.m. in a way audible to an adjacent property, structure or vehicle. The city does not need separate proof the sound was unreasonable once that audibility and time-of-day threshold is met.
Can yelling or singing at night get someone cited in Montebello?
Yes. Section 9.08.050(D) treats yelling, shouting, hooting, whistling or singing in a residential or commercial area between 8:00 p.m. and 7:00 a.m. as prima facie evidence that the activity disturbs the peace and quiet of a reasonable person, the same evidentiary shortcut the code applies to nighttime radio and stereo noise.
Does one noise complaint automatically mean a violation occurred in Montebello?
During the 8:00 p.m. to 7:00 a.m. window, an audible radio, stereo or yelling disturbance heard from an adjacent property is prima facie evidence of a violation under Section 9.08.050(B) or (D), but prima facie means the presumption can still be rebutted; outside those hours the same conduct must be shown to actually disturb a reasonable person's peace and quiet.
