How much landlord raise rent washington renters can face is now limited by state law. In 2025, Washington passed House Bill 1217, a statewide rent stabilization law. It took effect on May 7, 2025. For all of 2026, the maximum rent increase for most homes is 9.683%. That number comes from the Washington State Department of Commerce. If you just got a rent increase notice, this matters right now. Knowing how much landlord raise rent washington law allows can help you spot an illegal increase. It can also help you plan your budget before the new rent starts.
This guide explains the 2026 cap, the notice rules, and which homes are exempt. It also covers what you can do if your landlord asks for too much. In most cases, you have real options. However, the details depend on your type of housing and your lease.
How Much Landlord Raise Rent Washington Law Allows in 2026
The rule is written in RCW 59.18.700. It sets the yearly cap at 7% plus inflation, or 10%, whichever is lower. Inflation is measured by the Seattle-area Consumer Price Index (CPI). The CPI is a government number that tracks how fast prices rise.
Each year, the Department of Commerce figures out the next year’s cap. For 2026, that number is 9.683%. For example, if your rent is $1,800 a month, the most it can go up in 2026 is about $174. As a result, your new rent could not go over about $1,974. You can check the official number on the Department of Commerce HB 1217 resource page.
Timing rules also limit how much landlord raise rent washington tenants can be charged. A landlord cannot raise your rent during the first 12 months of your tenancy. After that, rent can go up only once in any 12-month period. Typically, that means one increase per year, at most.
Who Is Covered and Who Is Exempt
Most renters in Washington are covered by the cap. However, some homes are exempt. The question of how much landlord raise rent washington law permits depends on which group your home falls into. Here is a quick breakdown.
| Type of Housing | 2026 Rent Increase Limit |
|---|---|
| Most apartments and rental houses | 9.683% per year |
| Manufactured or mobile home lots | 5% per year |
| New buildings (first 12 years after occupancy permit) | Exempt from cap |
| Owner lives in one unit of a duplex, triplex, or fourplex | Exempt from cap |
| Public housing and some nonprofit or income-restricted housing | Exempt (other rules may apply) |
New construction is exempt for 12 years. That clock starts when the building gets its first certificate of occupancy. A certificate of occupancy is a city permit saying a building is safe to live in. For example, a building finished in 2020 stays exempt until 2032.
The owner-occupied exemption is narrow. The owner must actually live in one of the units. In most cases, it does not apply if a corporation owns the property. If you are unsure, ask your landlord in writing why they think your unit is exempt.
Notice Rules for a Rent Increase
Your landlord must give written notice before rent goes up. Under RCW 59.18.140, most tenants must get at least 90 days’ notice. Manufactured home tenants also get 90 days’ notice. The notice should state the new rent amount and the date it starts.
Some cities give even more protection. For example, Seattle requires 180 days’ notice for rent increases. Seattle may also require relocation help for some tenants facing big increases. Local rules can change how much landlord raise rent washington renters will actually pay. As a result, it is smart to check your city’s rules too.
If a notice arrives late, the increase may not be valid on the date listed. Typically, the increase cannot start until the full notice period has passed. Keep every notice you receive. Write down the date it arrived and how it was delivered.
What to Do If Your Rent Increase Is Too High
First, do the math. Multiply your current rent by 0.09683. Add that number to your current rent. If the new rent is higher, the increase may be illegal. This simple check shows how much landlord raise rent washington law allows for your unit.
Second, respond in writing. Politely tell your landlord the increase appears to exceed the 2026 cap. Cite RCW 59.18.700. Keep a copy of your letter or email. In many cases, landlords fix the error once it is pointed out.

Third, know your rights if the problem continues. If the increase is over the cap, you may end your lease early. You would give 20 days’ written notice, and you should not owe a penalty. You may also be able to recover the extra rent you paid. Damages can include up to three months’ rent, plus attorney fees and costs. The state can also seek civil penalties up to $7,500 per violation.
Finally, get help. You can file a complaint with the Washington Attorney General’s landlord-tenant office. You can also call a local legal-aid office, such as the Northwest Justice Project. However, results depend on your facts. Check with your court or a local legal-aid office before taking action.
