2. Who Is Covered in Shoreline?

In Shoreline, the rent increase cap applies to virtually all residential rental properties, regardless of when they were built. This means tenants in both older and newer buildings benefit from the same protections after their first year of tenancy.

Key Points:

• No construction year cutoff – Unlike some states, Washington applies the cap to properties of all ages
• 12-month waiting period – Rent increases are not permitted during the first 12 months of tenancy
• Property types – Apartments, houses, condos, and other residential rentals are covered

Exemptions:

• Properties exempt from RCW 59.18

3. Maximum Allowable Rent Increases

Landlords in Shoreline can increase rent by up to **9.683%** in 2026, which represents 7% plus inflation (CPI), with a maximum cap of 10% per year. The exact percentage is recalculated each year based on June CPI 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
• First-year tenants may see increases above the cap (but still need 90-day notice)

4. Notice Requirements for Rent Increases

Rent increases require **90 days advance written notice** to tenants.

Notice Requirements:

• Statewide: 90 days written notice required
• Frequency: Once per 12-month period
• The notice must include the amount of the increase, new rent amount, and effective date

5. 12-Month Waiting Period

Tenants in Shoreline are protected from rent increases during their **first 12 months** of occupancy. After this initial period, rent increases are subject to the annual cap.

How It Works:

• During your first 12 months, landlords cannot increase rent
• After 12 months, rent increases are subject to the annual cap
• This protection applies to all covered properties, regardless of age
