King County itself does not ban gas-powered leaf blowers countywide, but several cities including Seattle are phasing out gas blowers, and noise rules in KCC 12.86 apply to all power equipment.
Unincorporated King County has no outright gas leaf blower ban. Operators must still meet KCC 12.86 noise limits, which restrict sound from motorized equipment near residential property lines and during early morning and late evening hours. Seattle has adopted a phased gas-blower phase-out for city operations and is expanding to private use, while Mercer Island, Bellevue, and other cities are studying restrictions. Washington's Department of Ecology regulates small-engine emissions through statewide rules.
Operating equipment outside KCC 12.86 hours or above decibel limits can trigger civil infractions; specific city rules layer on additional penalties for gasoline-powered units.
