Island County, Washington Eviction Risk: Elevated

Island County, Washington eviction laws carries a county-average eviction-risk score of 6.8/10 (Moderate), placing it at rank 27 of 39 Washington counties, where rank 1 is the highest-risk. That position means 26 counties in the state are riskier for landlords, and only 12 are more favorable, putting Island County in the lower-risk third of Washington. For a landlord deciding where to deploy capital, that context matters: this is not a hostile market by state standards, but the Moderate label is not a green light either.

Across the county's 14 cities, risk scores range from 4.4 to 5.5, a gap of 1.1 points that reflects meaningfully different operating environments within a small geographic footprint. Average rent sits at $1,682, and 34.4% of residents rent rather than own, giving landlords a viable tenant pool. The average rent burden of 31% of income is worth watching: tenants at that level have limited cushion when income dips, which translates to collection risk that smart underwriting should price in.

The cities inside Island County

The highest-risk locations in the county are Freeland (5.5/10), Camano (5.4/10, population 17,303), and Clinton (5.4/10). These three communities sit noticeably above the county average and warrant closer due-diligence on tenant screening, lease terms, and reserves before purchasing. Freeland and Clinton are smaller communities, but Camano's size, at over 17,000 residents, makes it the most consequential high-risk market in the county by volume.

At the other end of the spectrum, Lake Ketchum (4.5/10), Sunday Lake (4.6/10), and Oak Harbor (4.8/10) are the lowest-risk cities in the county. Oak Harbor is the largest city in Island County at a population of 24,362, and its comparatively lower score reflects more stable operating conditions. Coupeville (4.9/10, population 1,980) also sits in the lower tier. The 1.1-point spread across these cities underscores how hyper-local eviction risk is: two properties on opposite sides of the county can carry materially different risk profiles despite sharing the same county-level legal framework.

State-level laws that apply here

Every landlord in Island County operates under Washington state law, specifically RCW § 59.18 (Residential Landlord-Tenant Act). Notice requirements depend on the reason for eviction: nonpayment of rent requires a 14-day notice (RCW 59.18.057), a material and curable lease breach requires 10 days (RCW 59.12.030(4)), and waste, nuisance, or unlawful activity can be addressed with a 3-day notice (RCW 59.12.030(5)). No-cause terminations for tenancies under six months require 20 days, while just-cause no-fault terminations such as owner move-in or substantial rehabilitation require a full 90-day notice under RCW 59.18.650. Understanding the Washington eviction process before a problem arises is essential, because an uncontested case still takes 30 to 60 days from filing to resolution, and a contested matter can stretch to 60 to 150 days.

Procedural costs add up quickly. The court filing fee is a flat $83, sheriff lockout fees run $50 to $150, and attorney fees typically range from $1,000 to $3,500. Washington also requires just-cause justification to end a tenancy and caps annual rent increases at 7% plus CPI, with a maximum of 10%. Source of income is a protected class under state law. Landlords should review Washington eviction costs and Washington tenant protections carefully before acquiring rental property anywhere in the state, Island County included.
