The “three strikes” rule actually is slang for two independent grounds for eviction. RCW 59.20.080 (1)(h) provides that a community owner may terminate a tenancy if the landlord serves a tenant three fifteen-day notices, within a twelve month period, to comply with the material terms of the rental agreement or park rules. (The twelve-month period commences with the date of the first notice).
RCW 59.20.080 (1)(m) provides that a park owner may terminate a tenancy if a tenant is served three five-day notices to pay rent or vacate within any twelve-month period, commencing with the date of the first violation.
Both of these grounds for termination require that each “strike” be memorialized by delivery of the appropriate notice. In case of rules violations, fifteen-day notices (MHCW has a form notice) are served on the tenant, pursuant to RCW 59.20.150, setting forth the rule or duty violated and how such rule or duty was violated. In a case of failure to timely pay rent, five day notices (MHCW has a form notice) are served on the tenant, pursuant to RCW 59.20.150, setting forth the amount of rent and late charges owed.
Once you have fully complied with either of the above-stated grounds for termination, you may proceed to an unlawful detainer action. Mediation is not required under these grounds for termination.
