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

Auburn City Code Chapter 8.12 defines overgrown grass, weeds, and rank vegetation as public nuisances when they harbor rodents, create fire hazards, or detract from neighborhood appearance. The typical enforcement threshold is grass or weeds exceeding 12 inches (one foot) in height on developed residential or commercial parcels. Code enforcement responds to complaints; inspectors issue a courtesy notice giving 10 to 14 days for voluntary compliance before formal abatement. If the owner fails to mow, the city may hire a contractor to cut the lot and bill the owner, recording an unpaid balance as a lien. Exemptions apply to naturalized landscapes, native plant gardens, meadow-style plantings, and rain gardens that are part of an approved landscape plan or serve as permitted stormwater facilities. Undeveloped land, agricultural parcels, and critical area buffers (wetlands, streams) are also generally exempt. Report tall grass complaints to Auburn Code Enforcement at (253) 931-3040. Grass clippings must not be blown into streets or storm drains under ACC 8.28 stormwater rules.
