Cowlitz County, Washington Eviction Risk: Elevated

Cowlitz County carries an average eviction-risk score of 6.6/10 (Elevated), placing it 4th riskiest of 39 counties in Washington, with only three counties scoring higher statewide. For landlords, that positioning matters: the underlying conditions, a 40.5% renter share, a 14.3% poverty rate, and an average rent burden of 30.5%, point to a tenant base that is financially stretched and more prone to payment stress than the state average. Investors coming from lower-risk markets elsewhere in Washington eviction laws will find Cowlitz County demands tighter screening standards and more active lease management.

The county's 11 cities do not share that risk evenly. Scores range from a low of 5.9 to a high of 7/10, a spread wide enough that the right submarket materially changes the operating picture. Average rent runs $1,210 per month across the county, but cost exposure on an eviction can far exceed any single month's rent once legal fees enter the equation.

The cities inside Cowlitz County

Kelso sits at the top of the risk table with a score of 7/10, the highest in the county. Its population of 12,684 is concentrated in older rental housing stock, and the combination of elevated poverty and high renter share makes it the market where landlords most frequently absorb a contested eviction timeline. Longview, the county's largest city at 38,069 residents, scores 6.7/10, still well above the county average and in the Elevated tier. Together, Kelso and Longview eviction risk account for the bulk of the county's rental activity and carry the most consequential risk exposure for portfolio landlords.

Further down the list, Woodland scores 6.3/10 and Longview Heights comes in at the county's low end with 5.9/10. Lexington registers 6/10. The gap between Longview Heights and Kelso, 1.1 full points, is meaningful: a landlord operating exclusively in Longview Heights faces a materially different risk profile than one concentrated in Kelso. Risk in Cowlitz County is hyper-local, and city-level scores should drive underwriting decisions rather than the county average alone.

State-level laws that apply here

Washington eviction laws's Residential Landlord-Tenant Act (RCW § 59.18) governs every tenancy in Cowlitz County and sets firm procedural floors. For nonpayment of rent, the required notice period is 14 days under RCW 59.18.057, one of the longer pay-or-vacate windows in the region. A material, curable breach triggers a 10-day notice, while waste, nuisance, or unlawful activity compresses to 3 days. No-cause terminations for tenancies under six months require 20 days, and just-cause no-fault terminations such as owner move-in or substantial rehabilitation require a full 90 days. Washington eviction laws state law also mandates just-cause justification for most terminations, which raises the procedural bar for any landlord who needs to exit a problematic tenancy without a lease violation to cite.

On the cost side, the court filing fee is a flat $83, sheriff lockout fees range from $50 to $150, and attorney fees run $1,000 to $3,500 depending on complexity and whether the case is contested. An uncontested eviction resolves in roughly 30 to 60 days; a contested case can stretch to 60 to 150 days.
