Snohomish County sets no maximum lawn or grass height for private residential yards in unincorporated areas. The old Title 7 nuisance chapters are repealed, and Title 10 covers only chronic (crime-related) nuisance property, not overgrown lawns. Height rules come from your city or HOA.
There is no active Snohomish County Code section capping residential grass or lawn height. Former sanitation-nuisance chapters (SCC 7.16, 7.20, 7.24, 7.28, 7.32) are all marked "Repealed," and Title 10's nuisance provision (Ch. 10.75, Chronic Nuisance Property) targets properties tied to repeated criminal activity, not tall grass. County vegetation authority is limited to state-listed noxious weeds (RCW 17.10, enforced by the Snohomish County Noxious Weed Control Board) and Title 30 tree-canopy/landscaping standards for new development. Incorporated cities within the county (Everett, Lynnwood, Marysville, etc.) may impose their own weed-and-grass height limits, so check your city code if you live inside city limits.
No county grass-height fine. Overgrown vegetation is enforceable only if it qualifies as a state-listed noxious weed under RCW 17.10 or a chronic nuisance under SCC 10.75.
