Owning rental property in Washington State can be a strong long-term investment, but it also comes with a complex set of legal responsibilities. Washington has some of the most tenant-protective rental laws in the country, and failing to comply—even unintentionally—can expose landlords to fines, lawsuits, or delayed evictions.
Whether you are a first-time landlord or a seasoned investor, understanding the fundamentals of Washington State rental laws is essential to protecting your property and your income. Below is an overview of the most important areas every Washington landlord should understand.
1. Fair Housing and Tenant Screening Laws
Washington landlords must comply with both federal Fair Housing laws and Washington State’s expanded protections. In addition to federally protected classes, Washington law includes protections for:
Source of income (such as housing vouchers)
Sexual orientation and gender identity
Military or veteran status
Disability, including emotional support animals
When screening tenants, landlords must apply consistent criteria to all applicants and follow Washington’s First-in-Time rule in many jurisdictions. This means you generally must offer the rental to the first qualified applicant who meets your written screening criteria.
Landlords are also required to provide applicants with:
Written screening criteria
Disclosure of any screening fees
A written reason if an application is denied
2. Security Deposit Rules
Washington State has strict rules regarding security deposits. Key requirements include:
A written lease agreement is required to collect a deposit
A move-in condition checklist must be provided and signed
Deposits must be held in a trust account at a financial institution
Tenants must be informed in writing where the deposit is held
After move-out, landlords have 21 days to either:
Return the full deposit, or
Provide an itemized statement explaining any deductions
Failure to follow these rules can result in landlords being required to return the full deposit—sometimes up to twice the amount, plus legal fees.
3. Rent Increases and Rent Rules
Washington does not currently have statewide rent control, but rent increases are regulated.
For most month-to-month tenancies, landlords must provide:
At least 60 days’ written notice before increasing rent
Rent cannot be increased during a fixed-term lease unless the lease explicitly allows it. Additionally, local jurisdictions may impose stricter notice or disclosure requirements, so landlords must stay informed about city and county rules.
4. Required Notices and Entry Laws
Landlords in Washington may not enter a rental property without proper notice, except in emergencies.
Standard notice requirements include:
At least 48 hours’ notice for inspections or repairs
At least 24 hours’ notice before showing the property to prospective tenants or buyers
Notices must state the reason for entry and be delivered properly. Repeated or improper entry can be considered harassment and may expose landlords to legal action.
5. Maintenance and Habitability Obligations
Washington law places clear responsibility on landlords to provide and maintain habitable housing. This includes:
Weatherproofing and structural safety
Functioning plumbing, heating, and electrical systems
Adequate garbage disposal
Compliance with health and safety codes
If a landlord fails to make necessary repairs after proper notice, tenants may have legal remedies, including repair-and-deduct options or termination of the lease under specific conditions.
6. Eviction Laws and Just Cause Requirements
Washington State eviction laws are detailed and highly regulated. In many cases, landlords must have “just cause” to terminate a tenancy, particularly for month-to-month leases.
Common lawful reasons include:
Nonpayment of rent
Lease violations
Owner move-in or sale of the property
Substantial renovation or demolition
Evictions require proper written notice, strict timelines, and court approval. “Self-help” evictions—such as changing locks or shutting off utilities—are illegal and can result in severe penalties.
7. Why Professional Property Management Matters
Because Washington rental laws change frequently and vary by jurisdiction, many landlords choose to work with a professional property management company. Professional managers help ensure:
Compliance with current laws and local ordinances
Proper documentation and notices
Legally sound tenant screening
Reduced risk of costly legal mistakes
For landlords who want peace of mind and protection, professional management can be a critical asset.
Final Thoughts
Understanding Washington State rental laws is not optional—it is a core part of being a successful and compliant landlord. Staying informed, maintaining proper documentation, and following legal procedures can protect both your investment and your reputation.
If you want help navigating Washington’s rental regulations or ensuring your property is fully compliant, working with an experienced property management team can make all the difference.
