Washington Move-In Fee Installment Plans — Legal Requirements & Compliance Guide (2026)

What Changed: Washington's Move-In Fee Installment Plan Law

In 2023, Washington State enacted Senate Bill 5961 (SB 5961), which added RCW 59.18.610 to the state's landlord-tenant code. This law fundamentally changed how landlords can structure move-in fees by allowing installment payment arrangements—a tool designed to reduce financial barriers for tenants while giving landlords flexibility in fee collection.

Prior to this law, move-in fees (including security deposits, damage deposits, and other upfront charges) had to be paid in full before a tenant moved in. The new statute permits landlords to offer an alternative: spreading those fees across multiple installments paid after the tenant takes occupancy.

However, this flexibility comes with detailed compliance requirements. Many Washington landlords misunderstand or ignore these rules, exposing themselves to civil liability and regulatory enforcement. This guide walks you through the exact legal obligations under RCW 59.18.610 so you can offer installment plans safely.

Understanding Move-In Fees Under Washington Law

What Qualifies as a Move-In Fee?

RCW 59.18.610 applies to "move-in fees," which include:

• Security deposits
• Damage deposits
• Cleaning fees
• Move-in inspection fees
• Administrative or processing fees charged at lease signing
• Pet deposits or pet fees

The statute does not apply to regular rent, late fees, or utility deposits. If you're charging fees beyond the categories above, consult a Washington-licensed attorney about whether they qualify as "move-in fees" subject to these rules.

The Cap on Total Move-In Fees

Washington law also limits the total amount of move-in fees you can charge. Under RCW 59.18.270, the combined total of security deposits and other move-in fees cannot exceed one month's rent. This cap applies whether fees are paid upfront or through an installment plan.

For example: If monthly rent is $1,500, your total move-in fees (security deposit + damage deposit + pet deposit + cleaning fee + admin fee) cannot exceed $1,500. This is a separate compliance requirement that works alongside the installment plan rules.

Core Requirements of RCW 59.18.610

1. Written Disclosure Before Lease Signing (Non-Negotiable)

The centerpiece of RCW 59.18.610 is disclosure. You must provide tenants with written disclosure of all material terms of any installment plan before they sign the lease. This is not optional—it is a statutory requirement.

What must be disclosed:

• The total amount of the move-in fee
• The number of installments
• The amount of each installment payment
• The due date or payment schedule for each installment
• Any late payment fees or consequences if an installment is not paid on time
• Whether prepayment is allowed and if there are any prepayment penalties (there cannot be any)
• The method of payment accepted (e.g., check, ACH, credit card, online portal)

Timing requirement: This disclosure must be provided before the tenant signs the lease—not after, not verbally, not "we'll send it to you later." If a tenant can point to evidence that they signed the lease without receiving written disclosure of the installment terms, you are in violation of the statute.

Format requirement: The disclosure must be in writing. Email works. Text does not. A printed handout works. A verbal conversation does not. Courts and the Washington Attorney General will enforce this strictly.

2. Installments Must Be Separate From Rent

This is a critical distinction that many landlords get wrong: installment payments for move-in fees must be billed and collected separately from regular rent payments.

You cannot send a tenant a single invoice for "$1,500 rent + $500 installment #1" or include installments in the monthly rent bill. The installment payment must appear on a separate invoice, be paid to a separate account, or be clearly itemized as distinct from rent.

Why does this matter? If installments are mixed with rent, and a tenant fails to pay, the collection and eviction process becomes legally complex. Washington courts have held that if move-in fees are bundled with rent, they may be treated as rent under the eviction statutes, which changes your remedies and procedural rights. Keep them separate to protect yourself.

3. No Prepayment Penalties (Statutory Ban)

RCW 59.18.610 explicitly prohibits prepayment penalties. A tenant can pay off their entire installment balance early without incurring:

• Additional fees
• Interest charges
• Acceleration of remaining installments
• Any other financial penalty

If your lease or agreement includes prepayment penalties, that clause is void. If you charge a tenant a prepayment penalty, you have violated the statute and exposed yourself to a civil claim.

4. Installment Payment Schedule Flexibility

The statute does not mandate when installments are due, only that the schedule must be disclosed in writing. Common structures include:

• Monthly installments: One installment due on the first of each month for 3-4 months
• Biweekly installments: Tied to tenant pay schedules
• Lump-sum payment after X months: First installment due at move-in, second due after 3 months

Whatever schedule you choose must be disclosed before lease signing and must be reasonable. A 12-month installment schedule may raise questions about whether you're effectively providing financing (which may trigger additional consumer protection regulations). Industry practice typically limits installment periods to 3-6 months.

Compliance Checklist for Move-In Fee Installment Plans

Before you offer an installment plan to a prospective tenant, use this checklist to ensure full compliance:

Compliance Requirement	Status	Documentation Needed
Total move-in fees do not exceed one month's rent	☐ Yes ☐ No	Calculation showing total fees ≤ monthly rent
Written disclosure provided before lease signing	☐ Yes ☐ No	Signed lease with dated disclosure attached or signed separately
Disclosure includes all material terms	☐ Yes ☐ No	Checklist: total amount, installments, amounts, dates, late fees, prepayment terms
Installments are billed separately from rent	☐ Yes ☐ No	Sample invoice showing separate line items for rent and installment
No prepayment penalties in lease or agreements	☐ Yes ☐ No	Lease language review; written confirmation tenant can prepay penalty-free
Payment methods clearly communicated	☐ Yes ☐ No	Written disclosure listing accepted payment methods
Records retained for at least 3 years	☐ Yes ☐ No	Folder or digital system with lease, disclosure, payment receipts, correspondence

What Happens If You Violate RCW 59.18.610?

Civil Liability

If you fail to comply with RCW 59.18.610, a tenant can sue you in civil court. Potential remedies include:

• Return of all installment payments — if the disclosure was improper or missing
• Damages: The tenant can recover actual damages (harm caused) plus statutory damages if the court finds willful violation
• Attorney fees: Washington courts often award attorney fees to the prevailing party in landlord-tenant disputes, so even if the dollar amount is small, legal costs can be substantial
• Treble damages: In some cases, courts award three times the actual damages if the violation was deemed intentional or reckless

Regulatory Enforcement

The Washington Attorney General's Office and local consumer protection divisions monitor landlord-tenant compliance. If a tenant files a complaint, you may face:

• Investigation by the Attorney General
• Demand to refund improperly charged fees
• Cease-and-desist orders against continuing the practice
• Civil penalties (the Attorney General can seek penalties for pattern violations)

Reputational and Operational Risk

Violations of RCW 59.18.610 often become public. Tenant complaints appear on review sites, social media, and legal databases. This affects your ability to attract quality tenants and can make future litigation more expensive as attorneys highlight a pattern of non-compliance.

Common Mistakes Landlords Make (And How to Avoid Them)

Mistake #1: Verbal Disclosure Only

The problem: Telling a tenant about the installment plan verbally, then sending the lease without written terms.

Why it fails: The statute requires written disclosure. Your word against the tenant's word in court is a losing position.

How to fix it: Create a written "Move-In Fee Installment Plan Agreement" that includes all material terms. Have the tenant sign it, dated, before they sign the lease. Keep a copy in your records.

Mistake #2: Bundling Installments With Rent Invoices

The problem: Sending one invoice that reads: "Rent: $1,500 | Move-In Installment #1: $375 | Total Due: $1,875"

Why it fails: The statute requires separate billing. This creates confusion and legal ambiguity if a dispute arises.

How to fix it: Send two invoices: one for rent, one for the move-in installment. Or use a property management platform that can itemize these separately (see LeaseBase Rent Payments).

Mistake #3: Including Prepayment Penalties in the Lease

The problem: Your lease states: "If tenant pays off the installment plan early, they forfeit the final month's installment" or "Prepayment triggers a $100 administrative fee."

Why it fails: RCW 59.18.610 explicitly bans prepayment penalties. This clause is void and unenforceable.

How to fix it: Review your lease template and remove any language that penalizes early payment. Affirmatively state that prepayment is allowed without penalty.

Mistake #4: Charging Unreasonable Late Fees for Missed Installments

The problem: Your disclosure states that a missed installment triggers a 10% fee or $200 late charge, with no cap.

Why it fails: While RCW 59.18.610 allows you to disclose late payment consequences, Washington courts scrutinize penalties that are disproportionate to actual harm. A 10% fee on a $375 installment ($37.50) is reasonable; a flat $200 on the same amount is not.

How to fix it: Cap late fees at 5-10% of the installment amount, or use a flat fee that is proportionate to the installment size (e.g., $25-50). Disclose this clearly in writing.

Mistake #5: Not Retaining Documentation

The problem: You delete emails, lose the signed disclosure, and don't keep payment records after 12 months.

Why it fails: If a tenant disputes the installment plan years later, you have no proof you disclosed the terms. You're at a disadvantage in any legal proceeding.

How to fix it: Keep a folder (physical or digital) for each tenant that includes: the signed lease, the signed installment disclosure, all payment receipts, correspondence about the installment plan, and any late payment notices. Retain for at least 3 years after the tenancy ends.

How to Draft a Compliant Move-In Fee Installment Disclosure

Here's a template structure for a written disclosure that meets RCW 59.18.610 requirements:

MOVE-IN FEE INSTALLMENT PLAN AGREEMENT

Property Address: [Address]
Tenant Name(s): [Name(s)]
Lease Commencement Date: [Date]

Total Move-In Fee Amount: $[Total]

Installment Schedule:
— Installment #1: $[Amount] — Due [Date]
— Installment #2: $[Amount] — Due [Date]
— Installment #3: $[Amount] — Due [Date]
[Add additional installments as needed]

Payment Instructions:
Make checks payable to [Landlord/Company Name] and mail to [Address]. Or pay online at [Portal/Link]. Or call [Phone] to arrange ACH transfer.

Late Payment Consequences:
If an installment is not received by the due date, a late fee of $[Amount or X%] will be charged. Repeated late payments may trigger additional remedies under RCW 59.18.

Prepayment Policy:
You may pay off your entire installment balance at any time without penalty or additional charges.

Separate From Rent:
This installment plan is separate from your monthly rent obligation. Rent and installment payments must be made separately.

Acknowledgment:
I/We acknowledge receipt of this disclosure and understand the terms of the move-in fee installment plan above. I/We agree to comply with this schedule.

Tenant Signature: _________________________ Date: _______
Landlord Signature: ________________________ Date: _______

Print this disclosure, have the tenant sign and date it, and attach it to the lease (or incorporate it into your lease document). Keep a signed copy in your records.

Integration With Your Rent Collection Workflow

To maintain compliance while managing move-in fee installment plans efficiently, your billing and collection system must treat installments separately from rent. This means:

• Separate invoicing: Issue distinct invoices for rent and installments, with different invoice numbers or line items
• Separate tracking: Track installment payments separately from rent payments (don't lump them together on a dashboard or report)
• Separate payment posting: When a tenant pays, clearly allocate the payment to the correct obligation
• Documented communication: If a tenant misses an installment or confuses rent with an installment, send clarifying communication in writing

If you're using a spreadsheet or manual system, this becomes error-prone and creates documentation gaps. Platforms like LeaseBase Rent Payments allow you to manage multiple billing streams per tenant and generate compliant invoices and payment records automatically.

Frequently Asked Questions

Q1: Can I require an installment plan, or must it be optional?

A: RCW 59.18.610 does not prohibit mandatory installment plans, but Washington policy favors tenant flexibility. Best practice is to offer installment plans as an option, allowing tenants to either pay the full move-in fee upfront or choose the installment route. This reduces legal exposure and demonstrates good-faith compliance with the statute's intent.

Q2: What if a tenant stops paying installments and I want to evict?

A: If an installment payment is missed, you have remedies similar to unpaid rent, but the process differs. You cannot immediately file for eviction based on a missed installment (unlike missed rent). Instead, you must follow the proper notice procedures under RCW 59.18.030 (notice to pay or quit). Consult a Washington-licensed attorney before pursuing eviction for unpaid installments, as courts treat this differently from rent default.

Q3: Can I offer different installment plans to different tenants?

A: Yes, you can customize installment terms based on the lease (e.g., offering a 3-month plan to one tenant and a 6-month plan to another), as long as each plan is disclosed in writing to that specific tenant before lease signing. However, do not discriminate based on protected class (race, religion, familial status, disability, etc.), as this would violate the Fair Housing Act and Washington's Law Against Discrimination.

Q4: Does the installment plan disclosure need to be a separate document, or can it be part of the lease?

A: It can be either. You may include the installment terms directly in the lease document (perhaps in a section titled "Move-In Fees"), or use a separate, signed agreement. The key requirement is that it be in writing and signed (or acknowledged) by the tenant before the lease is executed. Many landlords use a separate agreement to make it clear and prominent, reducing disputes.

Q5: What if I change the installment schedule after the lease is signed?

A: You cannot unilaterally change the installment schedule after the lease is signed. If you and the tenant agree to modify the schedule (e.g., the tenant requests to pay off the balance early), get written acknowledgment from the tenant. If you want to impose a new schedule without tenant consent, you are in violation of RCW 59.18.610 and subject to civil liability.

Compliance Resources and Next Steps

To ensure you're fully compliant with RCW 59.18.610 and other Washington landlord-tenant laws:

• Audit your current lease and disclosure forms: Review existing templates to ensure installment plan terms are disclosed in writing before lease signing, and that no prepayment penalties are included.
• Standardize your billing process: Implement a system that invoices rent and installments separately, with clear documentation for each tenant's payment schedule.
• Document everything: Create a retention system (physical or digital) that preserves signed leases, disclosures, payment records, and correspondence for at least 3 years.
• Stay current on law changes: Washington's legislature frequently updates landlord-tenant statutes. Subscribe to updates from the Washington Tenants Union, Attorney General's office, or a landlord association.
• Consult a local attorney: If you have questions about specific situations or want to review your templates, a Washington-licensed landlord-tenant attorney can provide guidance tailored to your portfolio.

For multi-unit portfolios, consider using a platform that automates compliance workflows. LeaseBase Compliance Engine helps you track move-in fee disclosures, installment schedules, and payment histories so you maintain records and enforce terms consistently across all tenants.

Conclusion

Washington's move-in fee installment plan law (RCW 59.18.610) gives landlords a valuable tool to attract tenants by reducing upfront financial barriers. But this flexibility comes with strict compliance requirements: written disclosure of all material terms, separate billing from rent, prohibition of prepayment penalties, and careful documentation.

Violations are not technical or minor—they expose you to civil liability, attorney fees, regulatory enforcement, and reputational damage. The cost of compliance (creating a one-page written disclosure and invoicing separately) is minimal compared to the cost of a lawsuit or regulatory action.

Use the checklist, template, and guidance in this article to implement compliant installment plans. If you manage multiple properties or have a large portfolio, automate the tracking and disclosure process to reduce human error and ensure consistency across all your leases.

Move-in fee installment plans can be a legitimate, profitable part of your tenant acquisition strategy—but only if you follow the law.
