Lewis County, Washington eviction laws carries an average eviction-risk score of 7/10 (Elevated) across its 14 incorporated cities, placing it 13th of 39 Washington counties, where rank 1 is the highest-risk.

The average rent burden across the county is 30.8% of income, a figure that tilts tenant finances toward vulnerability and puts upward pressure on nonpayment rates.

Both cities sit above the county average and warrant extra scrutiny on tenant screening, cash-flow buffers, and vacancy assumptions. Napavine scores 7/10, matching the county average, while Morton comes in at 6/10.

The lower end of the risk spectrum offers more favorable conditions. Winlock, Onalaska, and Toledo all score 5.5/10, and Mossyrock is the lowest-risk city in the data at 5/10. The 1.3-point gap between Mossyrock and Chehalis underscores how hyper-local risk actually is in this county: neighboring communities can have materially different tenant populations, local economies, and eviction histories. A portfolio split across the county's lower-risk cities looks quite different from one concentrated in Centralia or Chehalis.
