Washington Landlord-Tenant Law Guide

Every rental agreement in Washington must include specific disclosures:

• Lead-based paint disclosure for properties built before 1978
• Move-in checklist documenting the property condition
• Mold disclosure as required by state law
• Name and address of the property owner or authorized agent
• Fire safety information including smoke detector and carbon monoxide detector locations

Month-to-month tenancies require 60 days written notice to terminate in Seattle and many other jurisdictions (check your local ordinances as this varies).

Washington has strict rules governing security deposits:

• No statutory limit on deposit amounts (but must be reasonable)
• Deposits must be held in a trust account at a Washington bank
• Landlords must provide written notice of the bank name and address
• Return deposit within 30 days of tenancy end with itemized statement
• Failure to comply may result in 2x the deposit amount in damages

Different situations require different notice periods:

Landlords must maintain rental properties in habitable condition. For a complete breakdown of maintenance obligations, see our guide on landlord repair responsibilities in Washington. Required standards include:

• Functioning plumbing, heating, and electrical systems
• Weather-tight structure (roof, windows, doors)
• Working smoke detectors and carbon monoxide detectors
• Adequate garbage receptacles
• Locks on all exterior doors
• Hot and cold running water

Tenants have the right to repair and deduct for certain issues if landlords fail to make repairs within a reasonable time (typically 10 days for emergencies).

Washington State now requires just cause to terminate most tenancies. Valid reasons include:

• Non-payment of rent
• Material lease violations
• Owner or immediate family member intends to occupy
• Major renovation requiring vacancy
• Property being removed from rental market
• Sale to buyer who intends to occupy

Some jurisdictions like Seattle and Tacoma have additional local requirements. Always verify current local ordinances before proceeding with any tenancy termination.
