Quick Answer
Washington landlord tenant laws run through the Residential Landlord-Tenant Act, RCW Chapter 59.18. The biggest recent change is HB 1217, the state’s first statewide rent stabilization law. Rent increases are capped at the lesser of 7% plus inflation or 10% per year, with the 2026 limit set at 9.683%. Washington also requires “just cause” for ending most tenancies. A landlord can’t simply decline to renew a lease without citing one of the statutory reasons. Security deposits carry no statewide dollar cap but must be returned within 30 days. Nonpayment evictions require a 14-day notice using the state’s mandatory form.
Understanding Washington’s Landlord-Tenant Framework
The Residential Landlord-Tenant Act, RCW 59.18, sets most of the rules for Washington rental housing: security deposits, habitability, entry, and the eviction process. Two other chapters matter alongside it. RCW 59.12 governs the unlawful detainer court process landlords use to remove a tenant. Layered on top of that, RCW 59.18.650 sets a statewide “just cause” requirement. That means a landlord generally needs a specific, legally recognized reason to end most tenancies. The passage of time or a lease’s natural expiration isn’t enough on its own.
Layered over all of that, as of May 2025, is HB 1217, which created Washington’s first statewide rent stabilization program. You can read the full text of Washington’s landlord-tenant statutes directly from the Washington State Legislature’s RCW database.
Washington’s New Rent Stabilization Law (HB 1217)
Signed in May 2025 and in effect statewide since May 7, 2025, HB 1217 gave Washington its first rent cap, and it remains in effect until 2040. Three rules matter most.
The Cap Formula
Annual rent increases can’t exceed the lesser of 7% plus the Seattle-area Consumer Price Index, or 10%, whichever is lower. The Washington Department of Commerce recalculates this figure every year and publishes it in mid-July for the following calendar year. For 2026, that works out to 9.683%. A landlord also can’t raise rent at all during a tenant’s first 12 months. Manufactured or mobile home lot rent carries its own, lower cap of 5%.
Notice and Enforcement
Rent increases now require 90 days’ written notice, up from the 30-day minimum that applied before HB 1217, and some cities layer stricter local rules on top (Seattle requires 180 days for larger increases). If a landlord issues a notice above the legal cap, a tenant can terminate the lease penalty-free with 20 days’ notice. They can also sue directly for up to three times the amount charged above the cap. The Attorney General can also seek civil penalties of up to $7,500 per violation.
Exemptions
Not every rental falls under HB 1217. Buildings less than 12 years old, nonprofit and public housing authority units, and owner-occupied properties of four units or fewer are generally exempt. RentRedi’s guide to writing a rent increase notice covers how to structure a compliant increase notice. Checking your specific property against the current exemption list is worth doing before assuming the cap applies, or doesn’t.
Security Deposits in Washington
Washington sets no statewide dollar cap on security deposits, though the amount has to be disclosed in the written rental agreement, and Seattle has its own, stricter move-in cost limits. Two requirements make Washington’s deposit rules distinctive. First, the landlord must give the tenant a written, signed move-in checklist describing the unit’s condition before collecting any deposit. Without it, the landlord forfeits the right to withhold anything for damage. Second, the landlord must hold the deposit in a trust account at a Washington financial institution.
Once the tenancy ends, the landlord has 30 days to return the deposit or provide a full, itemized statement of deductions. That statement must include copies of estimates or invoices supporting any damage claims. Missing that deadline exposes a landlord to twice the deposit amount plus attorney’s fees. RentRedi’s guide to security deposits covers documenting move-in condition properly. Our recordkeeping guide covers keeping deposit funds separated the way Washington’s trust-account rule requires.
Just Cause: Washington’s Eviction Framework
Washington is a statewide just-cause state, one of a small number nationally. A landlord can’t simply choose not to renew a tenancy; ending one requires citing a specific, legally recognized reason.
Nonpayment of Rent
Nonpayment requires a 14-day notice to pay or vacate, and the notice has to use the Attorney General’s mandated statutory form. Washington courts have thrown out generic, out-of-state templates for omitting the required tenant-rights language, so a homemade notice is a real risk here. RentRedi’s guide to evicting a tenant walks through the filing and hearing process. Our eviction letter guide covers what a compliant notice needs to include.
Lease Violations
A substantial breach of a material lease term requires a comply-or-vacate notice with a cure deadline at least 10 days after service. Waste, nuisance, or criminal activity on the property allows a shorter path: at least 3 days’ written notice to quit, with no cure period required.
Ending a Periodic Tenancy
Because Washington requires just cause statewide, a landlord ending a month-to-month tenancy without a lease violation still needs to cite one of the statute’s enumerated reasons, selling the property, owner move-in, and substantial renovation are common examples, each with its own notice period. Our 30-day notice to vacate guide covers the tenant-side version of that notice.
Repairs, Entry, and Late Fees
Washington sets specific repair deadlines based on severity: 24 hours for a defect that cuts off hot or cold water, heat, or electricity, or is otherwise immediately hazardous; 72 hours for a broken refrigerator, range, or major plumbing fixture; and 10 days for everything else.
On entry, a landlord needs at least two days’ written notice for repairs, maintenance, or inspections. Showing the unit to a prospective tenant or buyer only requires one day’s notice. No notice is required in a genuine emergency or apparent abandonment. Violating the notice rule exposes a landlord to up to $100 per violation plus actual damages, and attorney’s fees if the conduct was willful.
Washington sets no statewide cap on late fees, but a landlord can’t charge one at all until rent is more than 5 days past due. In RentRedi’s own 2025 survey with BiggerPockets, units with tenants on autopay hit a 99% on-time rent rate, compared to 87% for units without it. That’s one of the more reliable ways to stay ahead of the 5-day line.
A Washington Landlord Reusing an Old Rent Increase Notice
Consider a landlord like Priya, a common scenario for anyone managing a handful of Washington units rather than a specific customer. Priya raised rent 12% last year without issue, before HB 1217 took effect. She plans to do the same this year using the same 30-day notice template she’s always used.
Both numbers are wrong now. The cap for 2026 sits at 9.683%, and the notice period has tripled to 90 days. A notice that repeats last year’s approach risks a penalty of up to three times the overcharge, on top of the Attorney General’s own enforcement authority. The fix is straightforward: check the current year’s published cap before sending any increase. Build the 90-day runway into the renewal calendar rather than treating it as an afterthought.
Common Mistakes Washington Landlords Make
Using Last Year’s Rent Cap Percentage
The cap changes every year based on CPI, and the Department of Commerce publishes the new figure each July. A notice that assumes last year’s number applies risks real liability under HB 1217.
Ending a Tenancy Without Citing Just Cause
Washington doesn’t allow a landlord to simply decline to renew. Every non-renewal or termination needs a specific, statutorily recognized reason, stated in the notice itself.
Skipping the Move-In Checklist
Without a signed, written checklist at move-in, a Washington landlord forfeits the right to withhold any part of the deposit for damage, regardless of how legitimate the damage claim is.
Using a Generic Nonpayment Notice Template
Washington’s 14-day notice has to track the Attorney General’s mandated form, including specific tenant-rights language. Courts have rejected notices that skip it.
FAQ
Washington changed more in the last two years than in most others in this series, and the questions renters and landlords are asking reflect that.
What is the new landlord-tenant law in Washington State?
The most significant recent change is HB 1217, effective since May 7, 2025, which created the state’s first rent stabilization program. Annual rent increases are capped at the lesser of 7% plus CPI or 10%, with a 2026 limit of 9.683%. The law also requires 90 days’ notice for any rent increase and bars increases entirely during a tenant’s first 12 months.
How much notice does a landlord need to give a tenant in Washington State?
It depends on the reason. Rent increases require 90 days under HB 1217. Nonpayment of rent requires a 14-day statutory notice. A curable lease violation requires at least 10 days, while waste, nuisance, or criminal activity allows a 3-day notice. Non-emergency entry requires two days, or one day for a showing.
How long does it take to evict a tenant in Washington State?
After the required notice period passes without compliance, the landlord files an unlawful detainer action under RCW 59.12. An uncontested case can resolve in a matter of weeks. A contested one, especially where the tenant raises a defense related to the rent cap or just-cause requirement, can take considerably longer.
What are my rights as a landlord in Washington State?
Landlords can raise rent up to the annual cap with proper notice, and enter for legitimate purposes with the required notice period. The statute also lets them end a tenancy for any of its recognized just-cause reasons, including nonpayment, lease violations, owner move-in, or sale of the property. They also have the right to hold a security deposit under the state’s trust-account and checklist rules.
Is Washington a landlord-friendly state?
Less so than many states covered in this series. Statewide rent stabilization, a just-cause requirement for ending most tenancies, mandatory notice forms, and real financial penalties for noncompliance all point toward a framework built around tenant stability. Landlords still retain meaningful rights, particularly around nonpayment and lease violations. Even so, Washington leans clearly toward tenant protections compared to states without rent control or just-cause rules.
How much can a landlord charge for a security deposit in Washington?
There’s no statewide dollar cap, though Seattle imposes its own, stricter move-in cost limits. Whatever the amount, it must be disclosed in a written rental agreement. It also has to be backed by a signed move-in checklist and held in a trust account. The deposit must be returned within 30 days of move-out with an itemized statement.
Does Washington’s rent cap apply to every rental property?
No. Buildings less than 12 years old, nonprofit and public housing authority units, and owner-occupied properties of four units or fewer are generally exempt from HB 1217. Confirming your property’s exemption status before assuming the cap applies, or doesn’t, is worth doing every year the exemption list gets revisited.
Conclusion
Washington rewards landlords who track the annual updates rather than repeat what worked last year: the rent cap changes every July, the notice periods differ by reason, and just cause means every non-renewal needs a real, stated basis. Read more of our state landlord tenant law guides here.
Next steps:
- Check this year’s published rent cap percentage before sending any increase notice. Confirm your property isn’t exempt from HB 1217 before assuming the cap applies.
- Review your nonpayment notice template against the Attorney General’s mandated 14-day form, since a generic template can get a case dismissed.
- Washington units need a system that keeps rent-increase notices, deposit deadlines, and just-cause documentation current automatically. See how RentRedi handles rent collection, lease e-signatures, and deposit tracking in one place.
