The Renewal Deadline Hiding on Your October Calendar
Count 90 days back from January 1, 2027, and you land on October 3, 2026. That is the last day to serve a notice for a New Year's rent increase under the state minimum, and in several cities near Bellevue, the window for that date has already closed.
This guide explains what the 10% cap for 2027 allows, which rentals are exempt, and how local rules change your renewal timeline. It comes from Brink Property Management, a family-owned firm providing Bellevue property management across Greater Seattle since 1996.
Key Takeaways
- The 2027 ceiling is 10%. The Department of Commerce set the maximum for covered increases taking effect between January 1 and December 31, 2027.
- Year one is off-limits. No rent increase may take effect during the first 12 months of a tenancy.
- Fees count too. The cap applies to rent plus recurring or periodic charges listed in the rental agreement.
- Local rules can add up to 90 days. Seattle, Redmond, Kirkland, and unincorporated King County require more notice than the state minimum in some cases.
- Exemptions must be proven in writing. Owners claiming an exemption must state the supporting facts in the notice itself.
What Washington's 2027 Rent Cap Allows
Before choosing a renewal number, start with the limits written into state law.
The 10% Ceiling
Under RCW 59.18.700, enacted through HB 1217 in May 2025, annual increases are limited to 7% plus the Seattle-area Consumer Price Index or 10%, whichever is lower. For 2027, the Washington State Department of Commerce set the maximum at the full 10% for increases taking effect between January 1 and December 31, 2027.
The effective date matters: increases taking effect before January still fall under the 2026 limit of 9.683%.
The First-Year Freeze and the 12-Month Window
No increase may take effect during the first 12 months of a tenancy. After that, total increases within any 12-month period cannot exceed the cap, and the state notice form tells tenants rent can rise once every 12 months.
A fixed-term lease adds another limit. An increase cannot take effect before the current lease term ends, even with proper notice.
Fees Count Toward the Cap
The statutory notice form treats rent as including recurring or periodic charges for use and occupancy. A 9% rent bump plus a new monthly parking charge can exceed the limit.
The law also limits the price gap between month-to-month and fixed-term agreements on the same unit to 5%. A month-to-month premium can't be used to sidestep the ceiling.
Which Rentals Sit Outside the Cap
Some Eastside rentals aren't bound by the 10% limit, but an exemption only helps if you can document it.
RCW 59.18.710 exempts several tenancy types:
- Newer buildings: Units whose first certificate of occupancy was issued 12 or fewer years before the notice date.
- Owner-occupied small properties: A duplex, triplex, or fourplex where the owner lived in one unit when the tenancy began and still does, plus certain shared-space and single-family owner-occupied arrangements.
- Regulated affordable housing: Units owned by public housing authorities or qualifying nonprofits, and certain tax-credit properties.
The owner-occupancy exemptions don't apply when the owner is a REIT, a corporation, or an LLC with a corporate member. For a closer look at the 12-year rule, read our guide to the new-construction carve-out in HB 1217.
Mapping Notice Deadlines Across the Eastside
Your notice deadline depends on where the property sits, not where you live.
The 90-Day Statewide Floor
RCW 59.18.140 requires at least 90 days' prior written notice of a rent increase. The notice must be substantially the same as the state form in RCW 59.18.720, which Commerce makes available through its landlord resource center.
Local Rules That Stretch the Timeline
Several jurisdictions near Bellevue require more lead time:
Seattle: 180 days for any housing cost increase, according to the City of Seattle.
Redmond: 120 days for increases over 3% and 180 days for increases over 10%, under RMC 9.54.030.
Kirkland: The same 120-day and 180-day tiers under its tenant protections ordinance.
Unincorporated King County: 120 days for increases over 3%, per King County.
Because the 2027 cap is 10%, a covered unit in Redmond or Kirkland raising rent more than 3% needs 120 days. The 180-day tier mainly affects exempt units going above 10%.
For a January 1, 2027 increase, those rules translate to a July 5 deadline in Seattle, September 3 in the 120-day jurisdictions, and October 3 under the state minimum.
Getting Service Right
Notices must be served as described in RCW 59.12.040. That means personal delivery, or leaving a copy with a person of suitable age and mailing a copy, or posting and mailing when no one is available. A text or email alone won't qualify.
A rent increase is only as strong as the paperwork behind it. Miss the date, the form, or the delivery method, and the new rent has to wait.
A Four-Step Plan for 2027 Renewals
Turn the rules into a checklist you can run for every lease on your calendar.
Audit Tenancy Dates
Confirm each tenant's move-in date, lease end date, and last increase date. New rent can't start until both the first-year freeze and the current term have ended.
Check Local Ordinances
Verify the jurisdiction for every address, since a mailing address doesn't always match city limits. Then apply the longest notice period that fits the size of your increase.
Document Exemptions
If a unit is exempt, pull the certificate of occupancy or occupancy records now and state those facts in the notice. An exemption you can't support leaves the increase exposed to the same remedies as any over-cap hike.
Use the Statutory Form
Serve the state's Rent and Fee Increase Notice, completed in full with the effective date, percentage, and dollar amounts. Detailed owner financial reporting makes it easier to confirm current rent and prior increase dates before you fill in the form.
Why a 10% Ceiling Isn't a 10% Target
The cap sets a legal maximum, and the most profitable renewal number often sits below it.
The Cost of a Noncompliant Notice
If an increase exceeds the cap without a valid exemption, the tenant can demand a correction and may end the lease with 20 days' written notice. Courts can award excess rent paid, up to three months of unlawful rent, and attorneys' fees, while the Attorney General can seek civil penalties of up to $7,500 per violation.
The Cost of Turnover
A vacancy costs money too. A moderate increase that keeps a reliable tenant can outperform a maximum increase that triggers cleaning, marketing, and weeks without rent, a dynamic covered in our post on the tenant retention advantage. Brink's vacancy loss calculator can help you weigh those trade-offs before you set a number.
Because the cap limits how fast rent can catch up, accurate rental market analysis at move-in sets a stronger baseline for future renewals.
Your best renewal is the one your tenant accepts. A fair, well-timed increase protects income and occupancy at the same time.
Frequently Asked Questions
These are the questions Eastside owners ask most often about 2027 renewals.
Can I raise rent 10% on every tenant in 2027?
Only on covered tenancies that are past the first 12 months, haven't had an increase in the prior 12 months, and have reached the end of the lease term. Ten percent is a ceiling rather than an entitlement, and recurring fees count toward it.
What happens if I missed the deadline for a January increase?
The increase takes effect later. Serve a compliant notice as soon as possible, and the new rent can begin once the full notice period has run and the current lease term has ended.
Does the cap still apply when a tenant moves out?
No. RCW 59.18.700 allows a landlord to adjust rent by any amount after a tenant vacates and the tenancy ends. The first-year freeze then applies to the new tenancy.
