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

Pasco does not exempt undeveloped or vacant parcels from its nuisance code. Under PMC 9.90.040 (Specific nuisances), conditions that commonly arise on vacant lots are declared public nuisances, including weeds, noxious weeds, grass and other vegetation that constitute a fire hazard, encroach on sidewalks or neighboring properties, damage public improvements, impair visibility of traffic signs or signals, or that have reached a height of 12 inches. Dead, dying or grown-and-died vegetation that is a fire hazard or otherwise a menace to public health, safety or welfare is also a nuisance, as are junkyards, dumping grounds and accumulations of rubbish or debris. The city's Common Code Violations guidance specifically lists weeds in excess of 12 inches, dust blowing onto neighboring properties, and parking on unimproved surfaces such as dirt or grass as enforcement priorities, all of which frequently affect vacant land. When a vacant lot is not maintained, PMC 9.90.100 authorizes the Director of Community and Economic Development (or designee) to send written notice to the owner; if the owner fails to act within the specified period, the city may clean and level the premises and remove weeds, vegetation, rubbish and debris, charging the cost to the owner. Unrecovered abatement costs may become a lien filed with the Franklin County Auditor. Vacant-lot owners should keep parcels mowed and clear and respond promptly to any notice.
