Seattle and King County Noxious Weed Board require control of listed invasive species. English ivy, Himalayan blackberry, and knotweed are top priorities. Salmon-safe landscaping practices encouraged throughout the city.
Seattle requires property owners to keep lots free of excessive weeds and overgrown vegetation. Washington has county-level Noxious Weed Control Boards per RCW 17.10 that maintain lists of noxious weeds property owners must control. Common targets include Scotch broom, Himalayan blackberry, knotweed, and purple loosestrife. City weed abatement enforced through code compliance. HOAs enforce stricter landscape standards. The wet western WA climate promotes aggressive weed growth. Native plant alternatives encouraged.
Notice to abate. City clears at owner's expense ($200 to $1,000+). Noxious weed violations: county enforcement + fines.
