Seattle vs Eastside Rental Rules: What Changes for Owners

CompareFacts checked November 8, 2026Reviewed by Gary E. Wilson, President and Designated Broker

State law is the floor everywhere

Every rental in Washington starts with the Residential Landlord-Tenant Act, chapter 59.18 RCW. The parts owners run into most often apply the same in Seattle, Bellevue or Redmond:

• At least 90 days' written notice before a rent increase, under RCW 59.18.140.
• The statewide limit on rent increases in RCW 59.18.700, in effect since May 7, 2025, with exemptions listed in RCW 59.18.710.
• Just cause rules for ending a tenancy in RCW 59.18.650.
• Written screening criteria before you screen, under RCW 59.18.257, and the source of income protections in RCW 59.18.255.
• Deposit, move-in checklist and deposit return rules, covered on the Washington security deposit law page.

What Seattle adds

Inside Seattle, city rules are added to state law, and you follow both. The main additions, as described on the city's own pages:

• Registration. The Rental Registration and Inspection Ordinance (RRIO) requires most rentals, including single houses, to be registered and inspected when selected.
• First-in-time screening. You must offer the rental to the first qualified applicant who submits a complete application. Renting in Seattle says to give at least 72 hours to supply missing information and 48 hours to respond to an offer.
• Fair Chance Housing. Limits on requiring or acting on criminal history in screening, under SMC 14.09.
• Longer rent increase notice. Since November 9, 2021, every housing cost increase needs at least 180 days' written notice, and larger increases can trigger relocation assistance.
• Move-in cost limits. The move-in fees page says the deposit and fees combined cannot exceed one month's rent, non-refundable fees may cover only cleaning and screening, and tenants may pay in installments.
• Seattle just cause. The city's ordinance covers expiring leases, requires a renewal offer unless a just cause applies, and requires RRIO compliance to end a covered tenancy.
• Timing limits on move-outs. The city's just cause page lists limits during the school year for students and school employees, and between December 1 and March 1 for low and moderate income renters when the owner owns four or more housing units.

What Eastside cities add

The Eastside is several cities, not one. Here is what each city's own site showed when we checked:

• Kirkland. The city's tenant protections page describes Ordinance O-4810, effective September 17, 2022. It requires longer notice for larger rent increases, 120 or 180 days depending on the size, and caps move-in fees and deposits, including pet deposits, at one month's rent in total.
• Redmond. The city's housing resources page says Redmond Municipal Code chapter 9.54 adds tenant protections. Notice of a rent increase is generally between 90 and 180 days depending on the amount, move-in fees and deposits combined may not exceed one month's rent, late fees are limited, and landlords must post a summary of the protections.
• Bellevue. The city's landlord-tenant page points owners and tenants to the state Landlord-Tenant Act and offers mediation through its Conflict Resolution Center.
• Renton. Landlords must register residential rentals with the city every year, as covered in the rental registration guide.

Do not forget unincorporated King County

Some Eastside addresses sit outside any city. There, county code applies instead of a city's. King County Code Title 12 protects people who use Section 8 or other housing subsidies, or alternative sources of income, in chapter 12.20. Chapter 12.25 adds tenant rules such as a move-in cost cap of one month's rent, installment payments and longer notice for some rent increases.

Before you set up a lease, confirm whether the home is inside city limits. The mailing address alone may not tell you.

How the layers change management

The rules themselves are not the hard part. The hard part is running the right version for each home. A Seattle rental usually needs city registration before it is advertised, a first-in-time process that records when each complete application arrives, a Fair Chance notice on the application, Seattle language on notices, and rent planning on a 180-day calendar. A Bellevue rental may run on state rules, while a Kirkland or Redmond rental has its own notice and move-in limits.

Rent planning shows the gap most clearly. In Seattle, a notice must be served so that a full 180 days pass before the new amount starts, not counting the day of service, and the increase has to line up with the start of a rental period. In Bellevue, the state's 90-day minimum is the usual starting point. An owner who uses one calendar for both will likely serve a Seattle notice too late.

Before you hire anyone to manage homes on both sides of the lake, it helps to ask a few plain questions:

• Which city or county rules apply to each of my homes, and how did you confirm the city limits?
• Do you keep separate application, lease and notice forms for Seattle, and who updates them?
• How do you track registration renewals and program inspections?
• How do you plan rent changes around Seattle's 180-day notice and the state limit?
