Mason County, Washington Eviction Risk: Elevated

Mason County carries an Elevated eviction-risk score of 6.1/10, placing it 12th among 39 counties in Washington eviction laws, meaning 11 counties are riskier and 27 are more landlord-friendly. That ranking puts Mason County firmly in the higher-risk third of the state, a reality landlords and investors need to price into their underwriting before committing capital here.

Across the county's 8 cities, scores span a 1.3-point range, from 5.3 at the low end up to 6.6 at the high end. An average rent of $1,304 pairs with a rent-burden rate of 29.7%, meaning a meaningful share of tenants are already stretched thin, which historically correlates with higher nonpayment rates and slower cure timelines when cash-flow problems arise.

The cities inside Mason County

The sharpest concentration of risk sits in Skokomish, which scores 6.6/10, the highest in the county, though its population of 560 limits its portfolio footprint. Shelton is the county seat and by far the largest market, home to 10,612 residents, and it scores 6.4/10, making it both the most consequential and second-riskiest city for landlords. Union comes in at 5.9/10, while Belfair, the county's second-largest community at 4,557 residents, scores 5.7/10, a more moderate risk profile that reflects its somewhat different tenant demographics.

On the lower end of the spectrum, Grapeview and Porter score 5.4 and 5.5 respectively, and both Malone and Hoodsport sit at 5.3/10, the floor for the county. Even those scores represent elevated conditions by statewide norms. The key takeaway is that risk in Mason County is hyper-local: a landlord invested in Shelton faces meaningfully different operating conditions than one holding units in Hoodsport, even within the same county framework and the same state statutes.

State-level laws that apply here

All Mason County landlords operate under RCW § 59.18, Washington eviction laws's Residential Landlord-Tenant Act. The notice calendar varies significantly by cause: nonpayment of rent requires a 14-day notice under RCW 59.18.057, a curable material breach triggers a 10-day notice, and waste or unlawful activity can be addressed with a 3-day notice. No-cause terminations carry longer lead times: 20 days for tenancies under six months, and 90 days for just-cause no-fault scenarios such as owner move-in or substantial rehabilitation under RCW 59.18.650. Washington state law requires just cause for most terminations and imposes a rent-increase cap formula of 7% plus CPI, capped at 10%.

On costs, landlords should budget carefully. The court filing fee is a flat $83, sheriff lockout fees run $50 to $150, and attorney fees for contested cases range from $1,000 to $3,500. An uncontested case resolves in roughly 30 to 60 days; a contested matter can stretch to 60 to 150 days. Washington eviction costs are not trivial even in straightforward cases, and a contested file can easily consume months of lost rent on top of direct legal expenses. Washington also designates source of income as a protected class under the Washington State Human Rights Commission, which affects screening decisions and requires careful compliance.

With a poverty rate of 16.8% and only 30.8% of residents renting, Mason County's rental market is relatively small but economically stressed, making tenant selection and lease terms critically important.
