Nuisance vegetation complaints in unincorporated Multnomah County are handled by Multnomah County Vector Control and Code Enforcement (503-988-3464). No specific statewide grass height ordinance exists for unincorporated county areas, but excessive overgrowth and nuisance plants are subject to county nuisance regulations.
Multnomah County Vector Control and Code Enforcement investigates nuisance conditions including excessive vegetation in unincorporated areas. Under ORS 452, the county has authority to address vegetation that creates vector control problems. Noxious weed eradication is required under Oregon Department of Agriculture rules. An intergovernmental agreement between the City of Portland and Multnomah County extends Portland's Nuisance Plants Required Removal Program to parts of unincorporated county for ODA-listed noxious weeds. Excessive vegetation that creates fire hazard, vector breeding habitat, or obstructs county roads may be subject to county abatement. Contact Vector Control and Code Enforcement: 503-988-3464.
Notice to abate. City abatement at owner’s expense ($200 to $1,000+). Administrative fees. Property lien for non-payment.
