Washington County regulates nuisance vegetation under Chapter 8.20 of the Code of Ordinances. Cities set specific grass height limits (typically 10 inches). Oregon state law (ORS 105.550–105.570) authorizes municipalities to enforce weed control and nuisance vegetation standards.
Washington County code compliance enforces maximum vegetation height on residential and commercial properties. Grass, weeds, and overgrown vegetation exceeding the height limit (typically 10 to 12 inches) constitute a public nuisance under ORS 105.550 to 105.570. Property owners receive a notice to abate with a compliance deadline (usually 10 to 30 days). If not corrected, the city may abate and charge costs via property lien. Oregon’s rainy climate means grass grows quickly - regular maintenance is essential.
Notice to abate. City abatement at owner’s expense ($200 to $1,000+). Administrative fees. Property lien for non-payment.
