Whatcom County, Washington Eviction Risk: High

Whatcom County carries an average eviction-risk score of 7/10 (Elevated) across its 19 cities, placing it squarely in the middle third of Washington state: 16 counties score higher and are less landlord-friendly, while 22 score lower. For a landlord or investor, that mid-table position means the operating environment is workable but not frictionless. Rents average $1,550 per month, renters make up 42.8% of households, and rent burden sits at 34.5%, a combination that keeps payment pressure consistently present and makes tenant screening discipline critical.

The intra-county spread, from 5.0 to 6.9, spans nearly two full points, which is meaningful when a single point can separate a smooth-running rental from one where eviction filings become routine. Investors evaluating the county as a whole will find the headline number reassuring compared to many Puget Sound markets, but the headline obscures sharp variation at the city level that should drive underwriting decisions.

The cities inside Whatcom County

Everson carries the county's highest risk score at 6.9/10, with a population of roughly 3,040. Point Roberts follows at 6.6/10, and Ferndale, the county's third-largest city at around 15,999 residents, checks in at 6.0/10. These three communities account for the ceiling of the range and warrant a closer look at local vacancy rates and tenant demographics before committing capital.

Bellingham, the county seat and by far the largest city at 93,438 residents, scores 7/10, matching the county average almost exactly. Lynden (5.1/10, population 16,234) and Birch Bay (5.3/10, population 10,837) represent the lower end of risk in the county. The takeaway for investors is that risk is genuinely hyper-local here: two properties six miles apart can face meaningfully different eviction odds depending on which municipality they sit in.

State-level laws that apply here

Every landlord in Whatcom County operates under Washington eviction laws's Residential Landlord-Tenant Act, RCW § 59.18. Notice requirements are layered by cause: nonpayment of rent triggers a 14-day notice under RCW 59.18.057, a curable material breach requires 10 days under RCW 59.12.030(4), and waste or nuisance is served with a 3-day notice under RCW 59.12.030(5). No-cause termination for tenancies under six months requires 20 days, while a just-cause no-fault termination such as an owner move-in or substantial rehab requires 90 days under RCW 59.18.650. Landlords with questions about sequencing these notices correctly should review the Washington eviction process before filing.

Washington eviction laws state requires just cause to end a tenancy, and the statewide rent cap formula is set at 7% plus CPI, capped at 10%. Filing fees run a flat $83.00; sheriff lockout fees range from $50 to $150; and attorney fees for a contested matter typically fall between $1,000 and 3,500. An uncontested eviction resolves in 30 to 60 days; a contested case can stretch to 60 to 150 days.
