What is a Residential Lease Agreement?
A residential lease agreement is a legally binding contract that gives a tenant the right to occupy and use property for a specific period in exchange for regular rental payments. This agreement stipulates the rights and responsibilities of both the landlord and tenant and brings the foundation for a successful rental relationship A clear, comprehensive lease agreement is the cornerstone of any successful Washington landlord-tenant relationship.
Crafting a legally enforceable lease goes beyond filling in a template: it requires close attention to Washington’s Residential Landlord Tenant Act, local ordinances, and tailored expectations for both landlords and tenants. This article highlights some essentials for ensuring compliance, protecting your rental property, and reducing the risk of costly disputes.
A Quick Note on Just Cause Eviction
Washington is one of several states that has imposed restrictions on the common law rules for evictions and other actions resulting in residential tenants being removed from their homes. At a state level, these are organized primarily in RCW 59.18.650, but local laws apply too. Under the state law, there are fundamental differences between qualifying term leases and periodic (or month-to-month) leases. Once a tenant has ever been on a periodic lease, many of the benefits of using term leases are lost forever. Check out our Just Cause Eviction article for more information.
Why You Should Have A Written Washington Lease Agreement
A common misconception we hear from our clients about tenants is that “they don’t have a lease, there’s nothing in writing.” But this is not the case. Oral agreements and/or the conduct of the parties can establish what is called an “oral lease” for residential property. These oral leases are periodic, or month-to-month, and are just as legally binding as written leases but without any of the benefits.
Using standardized written leases simplifies every stage of property ownership—from day-to-day management to lease renewals and eventual property sales. A uniform lease ensures consistency across tenancies, making it easier to reference terms, enforce obligations, and demonstrate compliance. When all tenants operate under the same framework, management decisions become more efficient, renewals follow predictable timelines, and prospective buyers can assess the property with confidence. In many cases, including those involving security deposits, Washington law requires that the terms be in writing.
Key Advantages of a Written, Uniform Lease:
- Defines Terms and Conditions: Establishes clear, consistent lease terms so both landlord and tenant understand their rights and obligations.
- Protects Rights and Responsibilities: Ensures compliance with state law while protecting the interests of both parties.
- Prevents Disputes and Legal Issues: Reduces ambiguity and minimizes the likelihood of misunderstandings or costly conflicts.
What Are The Essential Terms of a Washington Residential Lease Agreement?
Lease agreements should be comprehensive and compliant. Unlawful terms are unenforceable and most of a residential tenant’s rights are nonwaivable, regardless of what they agree to. Each agreement should be unique with specific details for the parties, rental premises, and rental terms. We elaborate on some of these specifics below:
- Names and Contact Information
Full names, addresses, and contact numbers of both the landlord and tenant (property manager too, if applicable).
- Property Description
Detailed address, description of the dwelling, bed/bath count, square footage, and any other property rented.
- Lease Term and Rent Amount
Duration of the lease with dates, rental amounts, payment due dates, and any late fee terms.
- Security Deposit and Fees
Specify the security deposit amount, non-refundable fees, and conditions for retaining the deposit.
- Rules and Regulations
Property use and conduct rules, such as noise levels, pet policies, and common area usage rules.
- Maintenance and Repairs
Responsibilities for property maintenance and repair procedures. Establish a protocol for tenants to report issues.
- Termination and Renewal Clause
Conditions and notice period for termination, renewal terms, and any options.
- Mandatory Disclosures
Federal, state, and local law all require disclosures. Common examples include lead paint, fire safety, and mold.
- Local Laws
15+ local Washington municipalities and counting have their own extra rules, be sure to double-check.
- Signatures of All Parties
Signed by the landlord, tenant, and any co-signers, with dates. The landlord must provide copies.
Again, all properties, units, tenants, and rental businesses are different. While forms are typically a great start for addressing most of the key issues, it is always important to pay attention to what is in the forms and be prepared to think critically when addressing unique circumstances.
Compliance with HB 1217
HB 1217 is a relatively new Washington law that governs a number of aspects of the leasing arrangement, including those concerning rent increases and required notices.
To learn more about these important provisions, please see this page on Landlord Compliance with HB 1217.
What Makes a Washington Lease Legally Enforceable?
To be enforceable, the lease must comply with:
- RCW 59.18 (Residential Landlord-Tenant Act)
- Local ordinances (e.g., Seattle’s Just Cause Eviction Ordinance, Tacoma’s rental housing code)
- State and federal disclosure requirements
Unlawful or unconscionable lease terms—such as waiving tenant rights or retaliating for complaints—are not enforceable under Washington law.
How Does “Just Cause” Eviction Affect Lease Terms?
Washington’s “Just Cause” eviction laws limit a landlord’s ability to terminate tenancies without a valid legal reason. These laws differ for fixed-term leases and periodic (month-to-month) tenancies.
Once a tenant is on a month-to-month basis, some advantages of fixed-term leases—like guaranteed end dates—may be lost.
Can I Use a Lease Form, or Do I Need a Residential Lease Lawyer?
While lease templates are a good starting point, they often miss critical nuances such as:
- Local city-specific requirements.
- Custom provisions for multi-unit or short-term rentals.
- Clauses dealing with subletting, pets, utilities, or renovations.
Our residential lease agreement attorneys can customize lease forms to your property or properties and review your current form lease or leases for compliance and suggested changes.
What Happens If I Don’t Have a Written Lease?
Without a written lease, your arrangement defaults to a month-to-month tenancy under Washington law. This can cause problems such as:
- Difficulty enforcing terms or collecting unpaid rent.
- Limited ability to recover damages or evict for cause.
- Increased disputes over repairs, deposits, or renewal rights.
A simple review by a residential lease attorney can help you avoid these costly pitfalls.
