How Compton Handles Noise Ordinances: A Practical Guide

Compton maintains 136 local ordinances across all categories, and 6 of those deal specifically with noise ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Compton falls on the strict-to-permissive spectrum compared to other cities.

Quiet Hours

Compton bars residents from running a radio, TV, stereo, or musical instrument loudly enough to disturb neighbors between 10:00 p.m. and 7:00 a.m. Municipal Code Sec. 7-12.6(a) applies the rule in every residential zone, backed by a five-decibel prima facie standard in the same section.

Key details: Quiet hours: 10:00 p.m. to 7:00 a.m.. Applies to: Residential zones citywide. Covered devices: Radios, TVs, stereos, instruments. Violation class: Misdemeanor. Extra remedy: Court injunction for repeat nuisance.

Running a radio, TV, or musical instrument loud enough to disturb a neighbor's peace between 10:00 p.m. and 7:00 a.m. is a misdemeanor under Sec. 7-12.5, enforced through Chapter 1, Sec. 1-6's general fine schedule. Compton Police can also ask a court for an injunction to shut down chronic nighttime noise from a repeat address.

Amplified Music & Outdoor Sound

Anyone using a loudspeaker or sound truck on Compton streets must first register with the Police Chief. Noncommercial use is capped at four hours a day, split between 11:30 a.m.-1:30 p.m. and 4:30-6:30 p.m., banned entirely on Sundays and holidays, and limited to 15 watts of power under Municipal Code Section 7-12.15.

Key details: Registration: filed with Police Chief 14 days ahead. Noncommercial hours: 11:30am-1:30pm and 4:30-6:30pm only. Power cap: 15 watts in final amplification stage. No-sound buffer: 100 yards of hospitals, schools, churches. Audibility limit: not audible beyond 100 feet.

Operating without registration or the required commercial license, or breaking any hours, wattage, buffer-zone or content rule, is a misdemeanor under Section 7-12.5, punishable under Chapter 1, Section 1-6.2, by a fine up to $1,000 and up to six months in jail, or both. Each day the violation continues counts as a separate offense, and a court may also issue a restraining order or injunction to abate the noise as a public nuisance.

This is not one of those rules that cities tend to ignore. Compton actively enforces its amplified music & outdoor sound requirements.

Construction Hours

Compton confines noisy building work, pile driving and excavation to 7:00 a.m.-7:00 p.m., Monday through Saturday, under Municipal Code Section 7-12.22, unless the noise stays fully enclosed inside a building or the Building Official issues a short emergency permit.

Key details: Permitted hours: 7:00 a.m.-7:00 p.m., Monday-Saturday. Sunday construction noise: not permitted outdoors. Emergency permit: from Building Official, max 3 days. Renewable: so long as the emergency exists. Equipment covered: pile drivers, steam shovels, hoists, hammers.

A contractor who runs prohibited equipment outside the permitted hours, or without a Building Official emergency permit, is guilty of a misdemeanor under Section 7-12.5, punishable under Chapter 1, Section 1-6.2 by a fine up to $1,000 and up to six months in jail. Each day the work continues outside the legal window is charged as a separate offense, and the City may also seek a civil injunction to stop the noise as a nuisance.

Vehicle Noise

Compton bans excessive vehicle stereo noise, altered mufflers and loud motorcycle exhausts under Municipal Code Sections 7-12.20, 7-12.21 and 7-12.27. A car stereo audible from 25 feet away, on public or private property, is treated as automatic evidence of a violation.

Key details: Audibility threshold: 25 feet = prima facie violation. Applies on: public and private property alike. Muffler required: on all combustion engines. Motorcycle mod ban: exhaust louder than stock. Exemptions: emergency and authorized City vehicles.

Violating the muffler, motorcycle or vehicle-stereo standards is a misdemeanor under Section 7-12.5, which covers all of Section 7-12 et seq. Under Chapter 1, Section 1-6.2 the maximum penalty is a $1,000 fine, six months in jail, or both, and each continuing violation may also be charged separately or addressed through a civil injunction abating the noise as a public nuisance.

Decibel Limits

Compton treats any noise that exceeds the ambient level at a property line, or inside an adjoining apartment, by more than five decibels as automatic evidence of a noise violation. Municipal Code Sec. 7-12.6(b) sets that five-decibel threshold, measured with an A-weighted sound level meter under Sec. 7-12.3.

Key details: Decibel threshold: 5 dB over ambient noise level. Measured at: Property line or adjoining unit. Meter standard: A-weighted sound level meter. Violation class: Misdemeanor, prima facie proof. Related rule: Same 5 dB test for HVAC, Sec. 7-12.11.

A property-line reading more than five decibels above the ambient noise level is, by itself, prima facie evidence of a violation under Sec. 7-12.6(b), no additional proof of annoyance required. Measurements must use an A-weighted sound level meter per Sec. 7-12.3. Violations are misdemeanors under Sec. 7-12.5, fined per Chapter 1, Sec. 1-6, with injunctive relief available for repeat offenders.

Barking Dogs

Compton bars keeping any animal, bird or fowl whose noise disturbs neighbors, through two overlapping Municipal Code sections: 7-12.10 for residential-zone keeping and 7-12.26 for any animal anywhere whose frequent, long-continued noise breaks a neighbor's peace.

Key details: Numeric threshold: none; reasonable-person standard used. Overlapping sections: Sec. 7-12.10 and Sec. 7-12.26. Zone limitation: 7-12.10 applies in residential zones. Covers: any animal, bird or fowl kept. Penalty: misdemeanor, up to $1,000/6 months.

A sustained violation of either animal-noise section is a misdemeanor under the chapter's general enforcement provision, Section 7-12.5, punishable under Chapter 1, Section 1-6.2 by a fine of up to $1,000, up to six months in jail, or both. Each day the noise continues after a warning may be charged as a separate offense, and the City may seek a civil injunction to abate it as a nuisance.

Compton is more permissive than most cities when it comes to barking dogs. That said, there are still limits.

The Bottom Line

Compton's noise ordinances rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Compton is broadly strict or permissive.

These rules come from Compton's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
