3. Maximum Allowable Rent Increases

For 2026, the maximum allowable rent increase in West Richland is **9.683%** (7% + CPI, maximum 10%). This cap is determined annually by the Department of Commerce using Seattle-area inflation data.

2026 Rent Increase Cap:

• Maximum increase: 9.683% (7% + CPI, capped at 10%)

Important Rules:

• Only one rent increase per 12-month period is allowed
• Landlords must provide at least 90 days written notice before any increase
• The cap applies to tenants who have lived in the unit for at least 12 months
