Noise Ordinances in Kent, WA

If you live in Kent or are thinking about moving there, noise ordinances are one of those things you probably won't think about until they affect you directly. Kent has 6 specific rules on the books covering different aspects of noise ordinances, and some of them might surprise you.

Barking Dogs

Frequent, repetitive, or continuous barking or howling that disturbs a reasonable person's peace is a public disturbance under Kent City Code 9.02.680(A)(1)(e), a misdemeanor, unless the animal is at a shelter, licensed kennel, veterinary hospital, or pet shop complying with Chapter 8.03 KCC.

Key details: Governing rule: KCC 9.02.680(A)(1)(e), public disturbance. Standard: Frequent, repetitive, or continuous animal sounds. Exemption: Licensed shelters, kennels, vet hospitals, pet shops. Exemption condition: Must comply with Chapter 8.03 KCC licensing. Penalty classification: Misdemeanor under KCC 9.02.680(C).

Chronic barking or howling that unreasonably disturbs a neighbor's peace is a misdemeanor under KCC 9.02.680(C), carrying Washington's standard misdemeanor exposure of up to 90 days in jail and a $1,000 fine under RCW 9A.20.021(3). Licensed shelters, kennels, veterinary hospitals, and pet shops in compliance with Chapter 8.03 KCC are exempt from the provision.

Aircraft Noise

Kent's noise code completely exempts aircraft noise from regulation: sound from aircraft in flight and sound originating at airports that's directly related to flight operations is excluded from every provision of KCC 8.05.090, the city's maximum permissible noise level standard. The exemption sits in KCC 8.05.140(2), alongside similar carve-outs for public-road traffic and interstate railroads.

Key details: Exempt provision: KCC 8.05.140(2). Covers: In-flight aircraft and flight-related airport sound. Not exempt: Non-flight engine testing/maintenance, daytime only (8.05.110(3)). Enforcement: None; noise control office has no jurisdiction. Related section: KCC 8.05.160 bars nuisance-noise claims too.

Because aircraft-in-flight and flight-related airport noise fall entirely outside KCC 8.05.090 and 8.05.180, the noise control office has no authority to issue a notice and order, assess the chapter's $250 civil fine, or treat the sound as a nuisance. A complaint filed under KCC 8.05.200 against exempted aircraft or airport noise will not result in enforcement action under Chapter 8.05.

The rules around aircraft noise in Kent lean permissive, but that does not mean anything goes.

Vehicle Noise

Kent outlaws motor vehicle sound systems loud enough to be heard 50 feet away, a $150 traffic infraction under KCC 9.36.045. The same chapter separately fines compression-brake noise at $100 and tire-squealing quick starts at $150, giving Kent police three distinct citations for excessive vehicle noise on city streets.

Key details: Stereo audibility limit: 50 feet from the vehicle. Stereo noise penalty: $150 infraction (KCC 9.36.045). Compression brake penalty: $100 infraction (KCC 9.36.060). Quick-start/tire-squeal penalty: $150 infraction (KCC 9.36.040). Enforcing agency: Kent Police Department.

A stereo-noise citation under KCC 9.36.045 is a $150 traffic infraction plus state fees, cited by any Kent police officer who can hear the vehicle from 50 feet. Compression-brake violations run $100 under KCC 9.36.060, and quick-start tire-squealing runs $150 under KCC 9.36.040. All three are civil infractions heard in Kent Municipal Court, not criminal charges, and drivers may contest or seek mitigation at a scheduled hearing.

Construction Hours

Kent's noise code exempts home maintenance and repair noise from its decibel limits only between 7:00 a.m. and 10:00 p.m., per KCC 8.05.110(1). Outside that window, or for work that isn't home repair, KCC 8.05.090's maximum permissible sound levels apply, and the building department's noise control office enforces violations with a $250 daily civil fine under KCC 8.05.280.

Key details: Exempt hours: 7:00 a.m. to 10:00 p.m. for home repair noise. Governing section: KCC 8.05.110(1). Enforcer: Building department noise control office. Civil fine: $250 per day, cumulative. Repeat penalty: Misdemeanor after 5 violations in 5 years.

Violating Kent's noise exemption window triggers a $250 civil fine per day under KCC 8.05.280(A), assessed after the noise control office serves a notice and order (KCC 8.05.220) and, absent a granted extension, an abatement notice (KCC 8.05.250) referring the case to the city attorney. Five separate violations within five years become a misdemeanor under KCC 8.05.280(B), carrying criminal penalties under KCC 1.01.140 on top of the accumulating $250-per-day civil fine.

Decibel Limits

Kent caps noise crossing onto a neighbor's property using a zone-based table: KCC 8.05.090 sets limits from 55 dBA (quiet residential to quiet residential) up to 70 dBA (industrial to industrial), measured at the receiving property, with a 10 dBA nighttime reduction for residential receivers.

Key details: Quietest limit: 55 dBA, Class A source to Class A receiver. Loudest limit: 70 dBA, Class C source to Class C receiver. Nighttime reduction: -10 dBA for Class A receivers, 10pm-7am. Civil fine: $250 per day. 5th offense in 5 years: Becomes a misdemeanor.

KCC 8.05.280 makes conduct unlawful under KCC 8.05.090 through 8.05.250 subject to a $250 civil fine, cumulative so each day of continued violation is a separate offense. Five separate subsequent offenses by the same violator within five years also become a misdemeanor, carrying criminal penalties under KCC 1.01.140 in addition to the $250-per-day civil fine. The building department, designated the noise control office under KCC 8.05.050, issues warnings, abatement notices, and citations.

Quiet Hours

Kent tightens its noise limits at night rather than banning sound outright: KCC 8.05.100(1) cuts the maximum permissible decibel levels in Table I by 10 dBA for any residential (Class A EDNA) property between 10:00 p.m. and 7:00 a.m. That drops the baseline Class A-to-Class A daytime limit of 55 dBA under KCC 8.05.090 down to 45 dBA overnight.

Key details: Nighttime window: 10:00 p.m. to 7:00 a.m.. Nighttime reduction: Table I limits cut by 10 dBA. Class A daytime cap: 55 dBA, residential to residential. Class A nighttime cap: 45 dBA, residential to residential. Civil fine: $250 per day under KCC 8.05.280.

A confirmed nighttime violation subjects the property owner or noise source operator to the same KCC 8.05.280 civil fine as a daytime violation: $250, cumulative for each day the excess noise continues after a notice and order. Five separate nighttime or daytime violations within a five-year period elevate to a misdemeanor, adding criminal penalties under KCC 1.01.140 to the accumulating civil fine.

The Bottom Line

Kent'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 Kent is broadly strict or permissive.

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