What a valid Washington rent increase notice includes
- • Full names of all tenants and the rental property address
- • The landlord’s name and mailing address
- • The current rent, the new rent, and the exact date the increase takes effect
- • Service at least 90 days before the effective date (Rev. Code Wash. § 59.18.140)
