Bellevue, WA Property Maintenance: Vacant Lot Maintenance (2026)

Owners of vacant and undeveloped lots in Bellevue are subject to the same property maintenance standards as occupied properties under Land Use Code 20.25E. Required maintenance includes: mowing or controlling vegetation over 12 inches in height; removing trash, debris, and illegal dumping; eliminating standing water that could breed mosquitoes; securing any structures against unauthorized entry; and maintaining fencing if present. Lots in Critical Areas (wetlands, streams, steep slopes, fish and wildlife habitat) cannot be cleared or graded without permits even to meet maintenance rules, and alternative management may be required. Vacant lots adjacent to residential uses must receive more frequent maintenance to prevent fire and rodent hazards. Owners of lots with recurring illegal dumping may be required to install fencing or gates. The city may perform emergency abatement if the property presents imminent health or safety risks, with costs billed to the owner as a property lien. Vacant lot violations can accrue fines of 100 to 500 dollars per day. Contact Code Compliance at 425-452-4570 with concerns.
