How Everett Handles Noise from Specific Sources: A Practical Guide
Everett maintains 131 local ordinances across all categories, and 5 of those deal specifically with noise from specific sources. Here is a breakdown of what the city actually requires, what is prohibited, and where Everett falls on the strict-to-permissive spectrum compared to other cities.
Low-Frequency Bass Limits
Everett's noise code defines 'plainly audible' to explicitly include detection of rhythmic bass alone: officers don't need to identify a song's lyrics or title, just hear the bass, to enforce nuisance and disturbance noise violations under Everett Municipal Code § 20.08.020.
Key details: Standard: Plainly audible = detectable by unaided ear. Bass rule: Rhythmic bass alone is enough. No ID needed: Song title/artist not required. Enforces: EMC 20.08.090 nuisance/disturbance noise.
Refusing or intentionally failing to stop a public nuisance or disturbance noise when directed by an enforcement officer is a misdemeanor; three prior violations in 365 days elevate a further offense to a gross misdemeanor.
Delivery Truck Noise
Everett bars truck loading areas from required building setbacks and requires noise mitigation, barriers, berms, walls, or limited hours, wherever a loading berth sits within 100 feet of residential zoning.
Key details: Setback rule: no loading area in required setbacks. Trigger distance: within 100 feet of residential zoning. Mitigation options: barriers, berms, walls, hour limits. Backstop standard: must meet city noise ordinance.
The city engineer reviews loading-area siting at permitting; sites within 100 feet of residential zoning lacking adequate barriers, berms, walls or hour limits are not approved, and separate citations apply under the city's noise control code for excess sound levels.
Car Alarm Limits
Everett prohibits the frequent, repetitive or continuous sounding of any vehicle horn, siren or alarm that's plainly audible across a property line or 50 feet from the source, unless it's genuinely warning of danger or legally required.
Key details: Prohibited: Frequent or continuous horn, siren or alarm noise. Distance test: Plainly audible 50 ft or across property line. Exception: Genuine danger warning or legally required. Penalty: Misdemeanor, escalating to gross misdemeanor. Citation: EMC § 20.08.090(B)(1).
A continuously sounding car alarm plainly audible 50 feet away is a misdemeanor nuisance-noise violation; repeat offenders within 365 days face a gross misdemeanor.
Generator Noise
Everett's noise ordinance exempts emergency standby and backup equipment, including backup generators, from all noise limits at all times, so long as the noise is tied to genuine emergency work or utility repair.
Key details: Exemption: Emergency standby/backup equipment, always. Condition: Tied to genuine emergency use. Chapter: EMC Ch. 20.08, Noise Control. Non-emergency use: Not covered by this exemption.
Running a backup generator during a genuine power outage or emergency draws no citation: it's exempt under § 20.08.100(A)(7). Non-emergency generator noise isn't covered by this exemption and can still violate the chapter's maximum permissible sound levels.
The rules around generator noise in Everett lean permissive, but that does not mean anything goes.
HVAC & Mechanical Noise
Everett regulates HVAC condensers and other fixed mechanical equipment the same way as commercial and industrial noise sources generally: through decibel-based measurement against the district-specific dB(A) caps in Everett Municipal Code § 20.08.040, not a plainly-audible complaint standard.
Key details: Standard used: Decibel-based measurement, not plainly-audible. Applies to: Fixed equipment in any zone. Numeric cap: 55-70 dB(A) by district. Nighttime: 10 dB(A) further cut near District I.
Fixed equipment (like HVAC condensers) exceeding the applicable district dB(A) cap is enforced through certified sound-level-meter readings under Chapter 1.20 EMC, with misdemeanor exposure for habitual violators.
The Bottom Line
Everett's noise from specific sources 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 Everett is broadly strict or permissive.
All of the above reflects Everett's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
