Washington Move-In Fee Installment Plans — SB 5961 Compliance Guide (2026)

What Is SB 5961 and Why It Matters to Your Screening Process

In 2023, Washington State passed SB 5961, codified in RCW 59.18.610, which fundamentally changed how landlords can structure move-in fees and, critically, how they can offer installment payment plans. For self-managing landlords working with 2-75 units, this law directly affects your tenant screening, lease execution, and debt collection processes.

The law addresses a real tension in the rental market: tenants with good credit or strong income often face significant upfront costs (deposits, fees, prorated rent) that create barriers to housing access. Installment plans lower that barrier. But without guardrails, installment agreements became predatory—landlords charged excessive interest rates, imposed unreasonable late fees, and used default clauses as leverage for eviction.

SB 5961 set clear rules. If you offer move-in fee installment plans, you must follow these requirements, or you face statutory penalties that include tenant damages, civil fines, and attorney fees. The statute applies whether you’re financing fees yourself or using a third-party payment platform. Non-compliance is not a gray area—it’s a specific violation with measurable consequences.

Scope and Applicability: When RCW 59.18.610 Applies

Move-in fees defined: Under RCW 59.18.610(1), “move-in fees” include deposits, application fees, administrative fees, cleaning fees, pet fees, or any other charge required as a condition of tenancy—except for rent itself. If you’re collecting it before or at move-in and it’s not base rent, it likely qualifies.

When the law applies: RCW 59.18.610 applies when:

• You offer a tenant an installment plan to pay move-in fees (regardless of whether the tenant accepts)
• The installment plan extends move-in fee payments beyond the date tenancy begins
• You are the owner, landlord, property manager, or authorized agent of the rental property in Washington State

When it does NOT apply: The statute does not govern rent payment installment plans, utilities, or charges unrelated to move-in fees. However, if you structure rent as an “application fee” or “admin fee,” it may be recharacterized as a move-in fee subject to the statute.

Core Requirements Under RCW 59.18.610: What You Must Do

1. Written Installment Agreement (Required Before Tenancy Begins)

RCW 59.18.610(2)(a) mandates a written agreement. This is not optional, and it is not satisfied by email exchanges or verbal agreements. The agreement must be in writing and provided to the tenant before tenancy commences.

What the agreement must include:

• Total amount owed (itemized by fee type)
• Number and amount of each installment payment
• Due date for each installment
• The interest rate (if any) expressed as a percentage per annum
• Late fee amount (and the statutory cap: lesser of 5% of installment or $50)
• Default triggers (what constitutes default)
• Consequences of default (notice requirements, cure periods, potential remedies)
• Statement that the agreement is binding on both parties

Practical compliance tip: Use a template specific to Washington State that incorporates all statutory language. Do not copy agreements from other states or modify residential lease language. The specificity of the installment agreement is a key enforcement point. If a tenant disputes late fees or default procedures, the clarity of your written agreement is your best defense.

2. Interest Rate Cap: Maximum 8% Per Annum

RCW 59.18.610(2)(c) explicitly states: “The installment payment agreement shall not provide for an interest rate in excess of eight percent per annum.”

This is a hard ceiling. Agreements that exceed 8% annual interest are void. The tenant is not obligated to pay the excess interest, and you cannot enforce it. Moreover, charging a rate above 8% constitutes a violation of the statute, exposing you to statutory damages.

Calculation example: If a tenant owes $2,000 in move-in fees split into four monthly installments of $500, and you charge 8% annual interest, the interest accrual is calculated as:

• Month 1: $500 × 0.08 ÷ 12 = $3.33
• Month 2: $500 × 0.08 ÷ 12 = $3.33 (on remaining principal)
• Total interest over 4 months: approximately $10

Most installment plans for move-in fees do not accrue interest, or accrue minimal interest. If you’re unsure whether your rate complies, consult a Washington State attorney licensed to practice consumer protection law.

3. Late Fee Limits: Lesser of 5% or $50 Per Installment

RCW 59.18.610(2)(d) restricts late fees on installment payments:

“Any late fees imposed shall not exceed the lesser of five percent of the installment amount or fifty dollars.”

Example calculations:

Installment Amount	5% of Installment	Compliant Late Fee Cap
$500	$25	$25 (lesser of $25 or $50)
$1,000	$50	$50 (tied; use $50)
$1,500	$75	$50 (lesser of $75 or $50)

Critical point: Late fees are applied per missed installment, not as a single lump sum. If a tenant misses two installments, you may charge late fees on each (capped separately). However, you cannot charge late fees on top of late fees or compound them.

Non-compliant late fee examples (violations):

• Charging $75 on a $1,000 installment (exceeds 5% cap)
• Charging $100 flat for any late payment (exceeds $50 limit)
• Charging a late fee plus an “administrative fee” for processing the late payment (the statute does not allow stacking)
• Applying late fees retroactively or after the grace period has expired

4. Default Procedures and Notice Requirements

RCW 59.18.610(3) specifies how you must handle installment payment defaults. You cannot accelerate the balance or pursue eviction based solely on installment non-payment without following statutory procedures.

Required default procedures:

1. Written notice of default: You must provide written notice to the tenant stating the specific installment(s) past due, the amount owed, and the date by which payment must be made.
2. Cure period: The tenant must be given a reasonable opportunity to cure the default. While the statute does not mandate a minimum cure period, industry standard and judicial interpretation suggest at least 5-10 business days.
3. No acceleration without breach: You cannot declare the entire balance due immediately unless the installment agreement explicitly authorizes acceleration, and even then, you must provide notice and an opportunity to cure first.
4. No eviction for installment-only defaults: RCW 59.18.610(3) clarifies that default on installment payments alone cannot trigger an unlawful detainer (eviction) action under RCW 59.12.030. You must pursue the debt through small claims court or collection, not through eviction.

Practical implication: If a tenant falls behind on an installment plan, your remedies are limited to:

• Pursuing the debt in small claims court or civil court
• Reporting the debt to credit reporting agencies (with proper verification)
• Using a collection agency (in compliance with the Fair Debt Collection Practices Act)

You cannot evict based on installment non-payment alone. If you try, the eviction will fail, and you may face counterclaims for wrongful eviction or statutory violations.

Prohibited Practices Under RCW 59.18.610

The statute defines what you cannot do:

No Acceleration Without Statutory Process

You cannot declare the entire installment balance due immediately upon a single missed payment, unless your agreement explicitly permits acceleration AND you follow the notice and cure procedures outlined above.

No Charging of Installment Fees

RCW 59.18.610(2)(b) states: “The installment payment agreement shall not provide for any charge or fee for offering an installment payment plan.” You cannot charge the tenant a “processing fee,” “payment plan fee,” or “administration fee” for the privilege of paying in installments. The only permissible charges are interest (up to 8%) and late fees (capped at 5% or $50).

No Waiver of Statutory Rights

Any clause in an installment agreement that purports to waive the tenant’s rights under RCW 59.18.610 is void. For example, you cannot include language stating “Tenant waives the right to a cure period” or “Tenant agrees that late fees may exceed 5%.” Such waivers are unenforceable.

No Retaliation or Adverse Action for Requesting Installments

While not explicitly stated in RCW 59.18.610, Washington’s broader tenant protection laws (RCW 59.18.240) prohibit retaliatory conduct. If a tenant requests an installment plan or defaults on one, you cannot increase rent, decrease services, or threaten eviction as retaliation.

Penalty for Non-Compliance: What You’re Risking

RCW 59.18.610(4) and the broader Consumer Protection Act (RCW 19.86) establish penalties for violations:

Violation Type	Potential Consequence	Enforcement
Charging excess interest (over 8%)	Actual damages + statutory damages up to $5,000	Tenant suit in small claims or civil court
Charging excess late fees (over 5%/$50)	Refund of excess + statutory damages + attorney fees	Tenant suit in small claims court
No written agreement or non-compliant agreement	Actual damages + civil penalties up to $5,000 per violation	Tenant suit; potential enforcement by Attorney General
Attempting eviction for installment-only default	Dismissal of eviction + damages + attorney fees	Tenant defense in eviction proceeding
Pattern of violations (multiple tenants)	Up to $7,500 civil penalty per violation under RCW 19.86	Washington State Attorney General Consumer Protection Act claim

Attorney fees: RCW 59.18.610(4) explicitly allows prevailing tenants to recover attorney fees and court costs. If a tenant sues you for a $200 late fee violation, the tenant’s attorney costs—which may easily exceed $1,500—become your liability.

Real-world scenario: A landlord in King County offers 12 tenants installment plans with 10% annual interest. One tenant, represented by a legal aid attorney, sues for excess interest charges of $120. The court awards the tenant $120 in damages, $5,000 in statutory penalties, and $2,500 in attorney fees. Total exposure: $7,620 on a single claim. Multiply by multiple tenants with similar violations, and statutory damages can compound quickly.

Step-by-Step Compliance Checklist for Move-In Fee Installment Plans

Before offering an installment plan:

• ☐ Obtain a Washington State-specific installment agreement template (or hire an attorney to draft one)
• ☐ Review the template against RCW 59.18.610(2) to confirm all required terms are included
• ☐ Confirm the interest rate does not exceed 8% per annum
• ☐ Verify late fee language states “lesser of 5% of installment or $50”
• ☐ Define default clearly (e.g., “failure to pay by the 5th business day after due date”)
• ☐ Include notice and cure procedures in the agreement
• ☐ Confirm there is no “installment plan fee” or “processing fee” language
• ☐ Ensure the agreement states it is binding and cannot be modified orally

When presenting to a tenant:

• ☐ Provide the written agreement before tenancy begins (not at move-in)
• ☐ Give the tenant a copy to keep
• ☐ Obtain the tenant’s signed acknowledgment that they received and understand the agreement
• ☐ Keep the signed agreement in your tenant file for at least the duration of the lease plus 3 years
• ☐ Do not modify the agreement after the tenant has signed it without a separate amendment signed by both parties

During the installment period:

• ☐ Send payment reminders with due dates (5-7 days before due date)
• ☐ Track payments meticulously (spreadsheet or property management software with audit trail)
• ☐ If a payment is late, send written notice of delinquency within 2 business days
• ☐ Include the amount due, due date, and cure period (suggest 5-10 business days)
• ☐ Apply late fees only after the cure period has passed, and only if the installment remains unpaid
• ☐ Do not attempt to accelerate the balance or evict based on installment non-payment alone
• ☐ If the tenant does not cure, pursue collection through small claims court, not eviction

Integration with Your Tenant Screening Process

Installment plans are a screening and retention tool. A tenant who cannot pay move-in fees upfront may still be an excellent long-term tenant if they have stable income. However, offering installments without proper controls creates risk.

Best practices for installment-based screening:

• Income verification: Require pay stubs or income documentation to confirm the tenant can afford installments plus monthly rent
• Credit check: Review credit reports for payment history on installment debt (auto loans, credit cards). Tenants with patterns of missed payments are higher risk
• References: Contact prior landlords to verify rent payment history and timeliness
• First installment due before move-in: Require the first installment to be paid before you deliver possession. This establishes payment capability and commitment
• Bank account verification: Confirm the tenant’s bank account is active and has sufficient funds to cover the initial installment
• Co-signer option: Offer tenants with weaker credit the option to add a co-signer to the installment agreement (ensure the co-signer also signs)

Proper screening reduces default risk and protects you from tenants who cannot realistically manage installment payments.

Third-Party Payment Platforms and Installment Services

Many Washington landlords use third-party platforms (such as rent payment apps or fintech companies) that offer installment financing to tenants. These platforms often charge *the tenant* interest or fees—not the landlord.

Your compliance responsibility: Even if you use a third-party platform, you remain liable for violations of RCW 59.18.610 if the platform’s terms do not comply. Specifically:

• Ensure the platform provides a written installment agreement that includes all statutory terms
• Verify the platform’s interest rate does not exceed 8% per annum
• Confirm late fees charged by the platform do not exceed 5% or $50
• Review the platform’s default and collection procedures to ensure they do not violate RCW 59.18.610(3) (e.g., no aggressive acceleration or retaliatory eviction threats)
• Maintain a copy of the platform’s installment agreement terms in your tenant file

If a tenant sues the platform for RCW 59.18.610 violations, you may be named as a co-defendant because you benefited from the arrangement. Vet your third-party providers carefully.

Interaction with Other Washington Landlord-Tenant Laws

RCW 59.18.610 does not exist in isolation. It intersects with other Washington protections:

Security Deposits and Move-In Fees

Security deposits are governed separately under RCW 59.18.260. A “security deposit” cannot be accessed by the landlord until the tenant moves out and it is applied to damages or unpaid rent. If you offer an installment plan on a “security deposit,” you are violating both RCW 59.18.260 and RCW 59.18.610 because the deposit is held in trust and cannot be reduced in installments.

Solution: Separate deposits from installment-eligible fees. Use clear terminology: “security deposit” (non-installment, held in trust) vs. “move-in fee” (installment-eligible).

Unlawful Detainer and Eviction

As noted above, RCW 59.18.610(3) explicitly prohibits eviction based on installment-only defaults. If you attempt to evict a tenant for non-payment of an installment plan, the eviction will be dismissed. The tenant may also countersue for wrongful eviction under RCW 59.18.240 (retaliation statute), exposing you to additional damages.

Notice and Disclosure Requirements

RCW 59.18.060 requires landlords to provide tenants with certain disclosures before or at lease signing. While RCW 59.18.610 is the specific installment plan statute, you should include clear language in your lease about whether installment plans are available and under what conditions. Tenants have a right to know this upfront.

Frequently Asked Questions

Q: Can I offer installment plans at my discretion, or must I offer them to all tenants?

A: You are not required to offer installment plans at all. RCW 59.18.610 does not mandate that landlords provide installment options. However, if you *do* offer them to any tenant, you must comply with the statute’s requirements for that tenant. You may apply consistent criteria (e.g., “installment plans available to tenants with income above 3x rent”) as long as you apply them consistently and do not discriminate based on protected classes (race, color, national origin, disability, etc.).

Q: If a tenant pays an installment late but eventually pays in full, can I still charge a late fee?

A: Yes, if the payment is past the due date and you have provided notice and a cure period, you may charge the late fee even if the tenant eventually pays. The late fee is a penalty for late payment, not a refundable charge. However, once the tenant pays (including the late fee), you cannot charge additional fees unless a subsequent installment is also late.

Q: Can I use an installment agreement from another state or a template I found online?

A: No. RCW 59.18.610 is Washington-specific, and agreements drafted for other states or generic templates will not comply with Washington law. Use a Washington State-specific template or hire an attorney. Non-compliance is costly.

Q: What if a tenant claims they never received the written installment agreement?

A: Document delivery carefully. Send the agreement via email (with read receipt), certified mail, or hand-deliver it. Obtain the tenant’s written or electronic acknowledgment that they received it. If you cannot prove delivery, you lose the statutory presumption that the agreement is valid, and the tenant may challenge your late fees or default procedures.

Q: Can I combine an installment plan with a co-signer requirement?

A: Yes. A co-signer can sign the installment agreement and be jointly liable for the debt. However, ensure the co-signer agreement complies with RCW 59.18.610 (same terms, rates, and procedures apply). Also, verify the co-signer is not a guarantor of the entire lease unless they sign a separate lease addendum—mixing guarantor and co-signer roles can create ambiguity about liability.

Practical Implementation: Sample Installment Agreement Language

Below is a simplified example of compliant language. This is not a complete agreement and should be reviewed by an attorney before use:

“MOVE-IN FEE INSTALLMENT AGREEMENT

Property Address: [Address]

Tenant Name: [Name]

1. Total Amount Owed: $[amount], comprised of:
– Security Deposit: $[amount]
– Application Fee: $[amount]
– Move-In Administrative Fee: $[amount]

2. Installment Schedule: Tenant agrees to pay the above amount in [number] installments as follows:
– Installment 1: $[amount] due on [date]
– Installment 2: $[amount] due on [date]
(etc.)

3. Interest Rate: Tenant agrees to pay interest on the outstanding balance at the rate of [0-8]% per annum. [OR: No interest will be charged.]

4. Late Fees: If an installment payment is not received by 5:00 PM on the due date, Tenant will be charged a late fee of the lesser of 5% of the installment amount or $50. Late fees will be due within 5 business days of notice.

5. Default: Default occurs if Tenant fails to pay an installment by the due date. Landlord will provide written notice to Tenant of the delinquency. Tenant has 10 business days to cure by paying the late installment in full plus any applicable late fees.

6. Remedies: If Tenant cures the default within the cure period, no further action will be taken. If Tenant does not cure, Landlord may pursue collection through small claims court or civil court. Tenant will be responsible for court costs and reasonable attorney fees.

7. No Acceleration Without Cure Opportunity: Landlord will not declare the entire remaining balance due unless Tenant fails to cure a default after receiving notice and a cure period of at least 10 business days.

8. Statutory Acknowledgment: This agreement is governed by RCW 59.18.610. Tenant has the right to cure any default as described herein. Tenant may not waive the rights granted under RCW 59.18.610.

Both parties acknowledge receipt of this agreement and agree to its terms.

Landlord/Authorized Agent: _________________________ Date: _______

Tenant: _________________________ Date: _______”

How Technology Can Help You Stay Compliant

Tracking installment payments, calculating late fees, and maintaining compliance documentation across multiple tenants is error-prone if done manually. Rent and fee payment systems that are Washington-compliant can help you:

• Generate compliant installment agreements automatically based on your lease and fee structure
• Track each installment payment and automatically flag late payments
• Calculate late fees within the 5% or $50 cap and prevent overcharges
• Maintain an audit trail of notices sent, payments received, and remedies applied
• Generate reports for tax or litigation purposes

Platforms like LeaseBase’s compliance-focused operations tools are designed to integrate installment management with your broader tenant file, so documentation is centralized and defensible.

Summary: Key Actions Before You Offer Installment Plans

If you manage a portfolio of 2-75 units and are considering offering move-in fee installment plans, here are the critical actions:

1. Obtain legal guidance: Consult a Washington State attorney to review your installment agreement template and fee structure.
2. Adopt a compliant agreement: Use a Washington State-specific agreement that includes all RCW 59.18.610(2) required terms.
3. Verify your fees: Confirm interest rates do not exceed 8% and late fees do not exceed 5% or $50.
4. Document everything: Maintain copies of all agreements, signed acknowledgments, payment records, and notices in your tenant file.
5. Train yourself on default procedures: Understand that installment-only defaults cannot result in eviction; use small claims court instead.
6. Implement technology: Use a rent payment or property management system that automates compliance tracking.
7. Review quarterly: Audit your installment agreements and payment practices against RCW 59.18.610 at least annually to catch any drift toward non-compliance.
