Noise Ordinances in Kent, WA: What Residents Actually Need to Know
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 9 specific rules on the books covering different aspects of noise ordinances, and some of them might surprise you.
Decibel Limits
Kent decibel limits follow WAC 173-60 and KCC 8.05 using EDNA zones. Residential receiving limit is 55 dBA day and 45 dBA night. Commercial sources are capped at 57 or 47 dBA into residential zones.
Key details: Residential Day: 55 dBA. Residential Night: 45 dBA. Meter Standard: WAC 173-58. Code: KCC 8.05 / WAC 173-60.
Exceeding the dBA matrix is a civil infraction under KCC 8.05. Measurements must follow WAC 173-58 sound level meter procedures for enforcement.
Leaf Blower Rules
Kent has no gas-powered leaf blower ban. Residential yard equipment is exempt from the 55 dBA limit between 7 AM and 10 PM under KCC 8.05. Outside that window, equipment must meet residential noise limits.
Key details: Allowed Hours: 7 AM to 10 PM. Gas Blower Ban: None in Kent. Night Limit: 45 dBA at property line. Code: KCC 8.05.100.
After-hours leaf blower operation that is clearly audible at a neighboring residential property is a civil infraction under KCC 8.05 enforced by Kent Police.
If you are coming from a city with tighter rules, you will find Kent gives residents more flexibility on leaf blower rules.
Industrial Noise
Kent industrial sources are capped at 70 dBA day and 65 dBA night at another industrial property, but only 60 dBA day and 50 dBA night when received at a residential property. KCC 8.05 and WAC 173-60 apply.
Key details: Industrial to Residential Day: 60 dBA. Industrial to Residential Night: 50 dBA. Industrial to Industrial: 70 dBA. Code: KCC 8.05 / WAC 173-60.
Industrial noise above WAC 173-60 limits at any residential or commercial receiving property is a civil infraction. Kent may escalate chronic problems to nuisance abatement.

Key details: Day Limit: 55 dBA residential. Night Limit: 45 dBA residential. Commercial to Residential: 57 day / 47 night. Code: KCC 8.05.090.

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