Bellevue, WA Landscaping Rules: Grass Height Limits (2026)

Bellevue City Code Chapter 9.06 Public Nuisances gives code enforcement authority over properties with overgrown vegetation, weeds, or unmaintained landscaping that constitute a public nuisance. Unlike some jurisdictions, Bellevue does not specify an exact grass height limit such as 6 or 12 inches. Instead, code enforcement officers evaluate complaints based on whether vegetation harbors pests, creates fire hazards, obstructs sight lines, encroaches on rights-of-way, or substantially detracts from neighborhood character. Complaints typically arise when grass reaches 12 inches or more and the property appears abandoned or neglected. Commercial properties and undeveloped lots face similar expectations. Noxious weeds listed by Washington State Noxious Weed Control Board and King County must be controlled under RCW 17.10. Property owners receive written notice and typically 10 to 30 days to remedy violations before fines accrue. Unresolved nuisance conditions can result in city abatement with costs charged to the property as a lien.
