What must a Washington residential lease include?
A Washington residential lease should include the names of the landlord and every tenant, the property address, the rent amount and due day, the lease term and start and end dates, the security deposit amount (up to no statewide cap in Washington), state-mandated disclosures (federal lead paint disclosure for pre-1978 units, plus any Washington-specific disclosures), and signature lines. Washington landlord-tenant law applies several mandatory terms even if the lease is silent. A Washington-specific lease template applies the correct clauses automatically. LeaseKit builds these from the relevant statutes.

This is an informational answer based on Washington landlord-tenant code as of early 2026. It is not legal advice. Housing law changes year to year and local ordinances (especially in rent-controlled or rent-stabilized cities) can override or add to state law. For contested cases, consult a Washington-licensed attorney.
