Arlington is a growing city of approximately 22,000 residents in Snohomish County, situated along the Stillaguamish River roughly 40 miles north of Seattle. As the broader Puget Sound housing market has pushed renters outward into communities like Arlington, demand for rental housing has increased, making an understanding of tenant rights especially important for local renters.
All residential rentals in Arlington are governed by Washington's Residential Landlord-Tenant Act (RLTA), codified at RCW 59.18. This law covers everything from security deposit handling and habitability standards to eviction procedures and anti-retaliation protections. Arlington has not enacted any local tenant-protection ordinances beyond what state law requires, so the RLTA is the primary source of renter rights in this city.
This page is intended as an informational overview to help Arlington renters understand the law — it is not legal advice. Laws can change, and your specific situation may require guidance from a licensed attorney or a local legal aid organization.
This city has no local rent control, and under RCW 35.21.830 no Washington city or county may enact it. This statewide preemption — extended to counties by RCW 36.01.130 — has barred local rent control since 1981, so no city in Washington has the authority to adopt its own rent cap or rent stabilization ordinance.
Rent in Washington is no longer unlimited, however. Under HB 1217 (RCW 59.18.700, effective May 7, 2025), residential rent increases are capped statewide at the lesser of 7% plus CPI or 10% in any 12-month period; the Washington Department of Commerce set the maximum allowable increase at 9.683% for the 2026 calendar year. A landlord may not raise the rent during the first 12 months of a tenancy, and must give at least 90 days' written notice before any increase takes effect. Units first occupied for residential use within the previous 12 years are exempt from the cap (RCW 59.18.710).
Rent still cannot be raised during a fixed-term lease unless the lease expressly allows it, and a landlord may never increase rent in retaliation for a tenant exercising a legal right, such as requesting repairs or reporting a code violation (RCW 59.18.240).
Washington's Residential Landlord-Tenant Act (RCW 59.18) provides Arlington renters with a robust set of protections across several key areas:
Habitability (RCW 59.18.060): Landlords must maintain rental units in a condition fit for human habitation. This includes keeping the structure weathertight and structurally safe, maintaining electrical, plumbing, heating, and hot-water systems in good working order, providing adequate garbage receptacles, and ensuring common areas are safe and sanitary. Tenants must notify the landlord in writing of defects.
Repairs (RCW 59.18.070 & 59.18.100): After receiving written notice of a repair need, landlords must make emergency repairs within 24 hours and non-emergency repairs within a reasonable time — generally interpreted as 10 days for serious conditions and up to 30 days for less urgent issues. If a landlord fails to act, tenants may pursue remedies including rent escrow, repair-and-deduct (up to one month's rent), or lease termination for serious violations.
Security Deposits (RCW 59.18.260–59.18.285): Landlords must provide a written rental agreement and a move-in checklist before accepting a deposit. Deposits must be held in a trust account. The full rules are detailed in the Security Deposit section below.
Notice Requirements (RCW 59.18.650; RCW 59.18.700): Washington requires just cause to end most residential tenancies; a landlord cannot terminate a month-to-month tenancy with a bare 20-day no-cause notice. The 20-day notice in RCW 59.18.200 is the tenant's notice to end a month-to-month tenancy. For covered residential tenancies, HB 1217 requires at least 90 days' written notice before a rent increase and caps 2026 increases at 9.683% after the first 12 months of tenancy, with RCW 59.18.710 exemptions including units whose first certificate of occupancy was issued within the past 12 years.
Anti-Retaliation (RCW 59.18.240): It is illegal for a landlord to increase rent, reduce services, threaten eviction, or take other adverse action against a tenant in retaliation for reporting code violations, contacting a government agency about housing conditions, organizing with other tenants, or exercising any other legal right. A tenant facing retaliation may raise it as a defense in eviction proceedings or sue for damages.
Lockout & Utility Shutoff Prohibition (RCW 59.18.290): Landlords are strictly prohibited from removing doors or windows, shutting off utilities, or taking any other self-help measures to force a tenant out. Only a court-issued writ of restitution enforced by a sheriff may lawfully remove a tenant from a rental unit.
Washington State's security deposit rules under RCW 59.18.260 through RCW 59.18.285 apply to all Arlington rentals. Key rules include:
No Statutory Cap: Washington law does not limit the maximum amount a landlord may charge as a security deposit. However, any deposit amount and the conditions for its return must be stated in a written rental agreement.
Move-In Checklist Required (RCW 59.18.260): Before accepting a security deposit, the landlord must provide a written checklist or statement describing the condition of the unit. Both parties must sign it. If no checklist is provided, the landlord forfeits the right to withhold any portion of the deposit for damages.
Trust Account Requirement (RCW 59.18.270): Security deposits must be deposited in a trust account in a Washington financial institution. The landlord must provide the tenant with written notice of the bank name and address where the deposit is held.
Return Deadline (RCW 59.18.280): Within 30 days after the tenant vacates and returns the keys, the landlord must either return the full deposit or provide a written, itemized statement of deductions along with any remaining balance. Allowable deductions include unpaid rent, damage beyond normal wear and tear, and cleaning costs if the unit was not left in the condition required by the lease.
Penalty for Non-Compliance (RCW 59.18.280): If a landlord wrongfully withholds a deposit or fails to provide the itemized statement within 30 days without a legitimate reason, a tenant may sue and recover up to twice the amount wrongfully withheld, plus court costs and reasonable attorney's fees.
Evictions in Arlington follow the process set out in Washington's Residential Landlord-Tenant Act (RCW 59.18.650 and related sections). Washington requires landlords to have a legally recognized just-cause reason before terminating a tenancy or filing for eviction.
Just-Cause Requirement (RCW 59.18.650): Landlords must cite one of 16 statutory just-cause reasons to end a tenancy. Common just-cause grounds include nonpayment of rent, material lease violation, engaging in criminal activity on the premises, the owner's intent to substantially rehabilitate or sell the property, and others listed in RCW 59.18.650(2). A landlord cannot simply decide not to renew a lease without a qualifying just-cause reason.
Notice Types and Periods:
Unlawful Detainer Filing (RCW 59.12): If the tenant does not comply with the notice, the landlord may file an Unlawful Detainer action in Snohomish County Superior Court. The tenant will receive a summons and has the right to appear and contest the eviction at a hearing. The court will decide whether the landlord has met the legal requirements.
Writ of Restitution: If the court rules in the landlord's favor, the court issues a Writ of Restitution, which is served by the Snohomish County Sheriff. Only the Sheriff may physically remove a tenant — landlords have no right to remove a tenant by force on their own.
Self-Help Eviction is Illegal (RCW 59.18.290): A landlord who changes locks, removes doors or windows, shuts off utilities, or takes other self-help measures to force a tenant out without a court order is breaking the law. Tenants subjected to self-help eviction may sue for actual damages, up to $2,000 in exemplary damages per violation, and attorney's fees.
No-cause termination is not a valid landlord path in Washington. Under the statewide just-cause law (RCW 59.18.650), a landlord may not end or decline to renew a periodic (month-to-month) tenancy without stating one of the statute's enumerated just-cause grounds. The 20-day notice under RCW 59.18.200 is the tenant's own notice to move out of a month-to-month tenancy — it is not a no-cause eviction tool for landlords. No-fault grounds such as the owner or a family member moving in, sale of the property to a buyer who will occupy it, or demolition or substantial rehabilitation each require at least 90 days' written notice under RCW 59.18.650(2).
