Pasco, WA Property Maintenance: Weeds & Overgrown Grass (2026)

Pasco sets a specific vegetation height limit. Under PMC 9.90.040 (Specific nuisances), weeds, noxious weeds, grass and other vegetation are a public nuisance when they constitute a fire hazard, encroach on sidewalks or neighboring properties, damage public improvements, impair the visibility of traffic signs or signals, or have reached a height of 12 inches. The code also treats trees, plants, shrubs, grass, brush, weeds or other vegetation that have grown and died and are a fire hazard or menace to public health, safety and welfare as nuisances, along with lawns, shrubs, trees or plantings that have been dead for more than three frost-free months. The city's Common Code Violations page confirms that weeds in excess of 12 inches, or weeds growing onto other properties, and dead/dying landscaping are routinely cited. Enforcement follows PMC 9.90.100: the Director of Community and Economic Development (or designee) notifies the owner or occupant in writing when weeds, grass, vegetation, rubbish or debris accumulate so as to become a fire hazard or injurious to public health. If the owner fails to remove the growth within the specified period, the city may enter, clean and level the premises, and remove the weeds and vegetation, charging the cost to the owner. Costs, plus reasonable legal and administrative expenses, may be assessed and secured by a lien filed with the Franklin County Auditor. Keeping grass and weeds below 12 inches and removing dead plantings keeps owners compliant.
