Walla Walla County, Washington Eviction Risk: Elevated

Walla Walla County lands at 6.8/10 (Moderate) on the eviction-risk scale, ranking 19th of 39 counties in Washington eviction laws, placing it squarely in the middle third of the state. That score tells landlords and investors they are not walking into a high-volatility environment, but they are not in the most landlord-friendly tier either: 18 counties carry more risk, and 20 sit below this county. With an average rent of $1,244 and a rent-burden rate of 34.6%, a meaningful portion of the tenant base is financially stretched, which matters when underwriting vacancy or non-payment exposure.

The county's 8 incorporated cities and communities span a narrow but meaningful range, from 4.5 at the low end to 5.5 at the high end. That one-point spread means that where inside the county a property sits changes the risk profile in ways that aggregate county numbers alone will not reveal. Operators who treat the county as monolithic are leaving due-diligence gaps.

The cities inside Walla Walla County

The city of Walla Walla anchors the upper end of the risk range at 5.5/10, with a population of 33,925, making it by far the county's largest market and its highest-risk one. Waitsburg scores 5.1/10, and College Place, with 9,854 residents, comes in at 5.0/10, sharing that score with the much smaller community of Prescott. These four cities are where tenant-side financial pressure and regulatory exposure are most concentrated.

Conditions ease as you move to the county's smaller communities. Burbank scores 4.9/10, Touchet 4.8/10, Walla Walla East 4.7/10, and Garrett sits at the county floor of 4.5/10, with a population of 1,697. The risk gradient is real: a landlord operating exclusively in Garrett or Walla Walla East operates in a materially different environment than one concentrated in the city of Walla Walla. Hyper-local underwriting, not county-level averages, is what makes the difference here.
