Just cause eviction rules in Washington County, OR — sometimes called tenant protection or "for cause" eviction ordinances — list the specific legal reasons a landlord can end a tenancy.
Oregon SB 608 requires landlord just cause to terminate a tenancy after the first 12 months. No-cause terminations are only allowed in the first year. Washington County enforces the statewide standard; Board Ordinance 888 extends 90-day no-cause notice countywide.
Under ORS 90.427, after 12 months of occupancy landlords must have qualifying cause to terminate: non-payment, material lease violation, repeat violations, or a landlord-based reason (sale to buyer occupying as principal residence, owner/family move-in, demolition/repair, conversion). For landlord-based (qualifying) terminations, landlords must pay one month's rent as relocation assistance (landlords with four or fewer units are exempt). In 2023, Washington County adopted an ordinance extending the statewide 60-day no-cause notice for first-year tenants to 90 days countywide, which the Board later aligned with the state's 90-day standard. Retaliatory and discriminatory evictions are separately prohibited under ORS 90.385 and ORS 659A.
Wrongful termination: tenant may recover up to 3 months rent plus actual damages and attorney fees. Failure to pay relocation assistance: liability for 3 months rent plus damages. Retaliation: treble damages possible.
