Key Takeaways
- Installment plans are allowed but heavily regulated — RCW 59.18.610 permits landlords to offer payment plans only for move-in costs, not rent
- Maximum 3 installments required — tenants cannot be forced to pay more than one-third of move-in fees upfront; remaining balance due within 30 days of move-in
- Disclosure requirements are strict — all installment terms must appear in the lease or separate written agreement before tenant signs; verbal agreements are not compliant
- No additional fees or interest allowed — landlords cannot charge processing fees, late fees, or interest on installment balances under RCW 59.18.610
- Violation penalties: $500–$2,000 per violation — tenants can sue under the Consumer Protection Act (RCW 19.86) and recover treble damages plus attorney fees
- Move-in fees include deposits, prepaid rent, and fees — security deposits, damage deposits, and any upfront charges all fall under this rule; understand what qualifies
What Washington Law Says About Move-In Fee Installment Plans
In October 2023, Washington State enacted SB 5961, codified in RCW 59.18.610, fundamentally changing how landlords can collect money from tenants at lease signing. For self-managing landlords in Washington, this law eliminates guesswork: you cannot require a tenant to pay all move-in costs upfront, and if you offer an installment plan, you must follow specific rules or face legal liability.
The statute is narrowly tailored. It applies only to "move-in costs"—a term of art in Washington law that includes:
- Security deposits (maximum one month's rent under RCW 59.18.140)
- Damage deposits (if allowed separately from security deposit)
- First month's rent
- Last month's rent (if collected upfront)
- Any other prepaid rent or fees due before occupancy
Importantly, this statute does not regulate regular rent payments after the tenant moves in. Tenants can be held to paying full rent on the due date. The law is specifically about the financial barrier to entry—the lump sum that prevents low-income tenants from securing housing.
How Many Installments Can You Require or Offer?
RCW 59.18.610(2) sets a clear cap: landlords may not require tenants to pay more than one-third of move-in costs at lease signing. The remaining balance must be collected within 30 days of the tenant's move-in date.
In practice, this means:
| Move-In Cost Total | Maximum Due at Signing | Due by (30 Days Post-Move-In) |
|---|---|---|
| $3,000 (security deposit + first month's rent) | $1,000 (one-third) | $2,000 |
| $4,500 (security + damage deposit + first + last month's rent) | $1,500 | $3,000 |
| $2,000 (security deposit only) | $666.67 (one-third, rounded) | $1,333.33 |
The law permits up to three total payments, but does not mandate that you offer installment plans at all. If you choose to allow installments, you control whether that's two payments or three, provided the first payment is no more than one-third of the total.
Critical compliance point: The 30-day window starts from the date the tenant physically occupies the unit, not from lease signing or move-in notice. Document the actual move-in date in writing.
Required Disclosures: What Must Be in Your Lease or Agreement
RCW 59.18.610(1) requires that any installment arrangement be disclosed in writing before the tenant signs the lease. This is not optional, and verbal agreements do not satisfy the statute. The Washington Attorney General's office has clarified that "writing" means:
- A separate installment agreement signed by both landlord and tenant, or
- Specific language in the lease document itself outlining payment schedule and terms
Your written disclosure must include:
- Total move-in cost amount (itemized by type: security deposit, first month's rent, etc.)
- Amount due at lease signing (expressed as a dollar amount and percentage)
- Due date for remaining installments (specific date, not "within 30 days")
- Whether late fees apply (they cannot under this statute, but you must be clear that no penalties attach)
- Consequence of non-payment (e.g., whether non-payment could lead to lease termination)
Example compliant lease language:
"MOVE-IN COST INSTALLMENT PLAN: Tenant agrees to pay move-in costs as follows: (1) Security Deposit: $1,200; (2) First Month's Rent: $1,800. Total Move-In Cost: $3,000. Payment Schedule: $1,000 due upon lease signing (one-third); remaining $2,000 due by [specific date, 30 days from move-in]. No late fees, interest, or additional charges apply to installment payments under Washington law. Failure to pay installments by due date may result in lease termination and eviction proceedings under RCW 59.12."
Vague language like "installments available upon request" or "flexible payment terms" does not comply. You must be specific about amounts and dates before the tenant signs.
What You Cannot Do: Prohibited Practices Under SB 5961
Washington's move-in fee statute explicitly prohibits several practices that landlords in other states may use:
No Late Fees or Interest on Installment Balances
RCW 59.18.610(3) states that no additional fees, interest, or penalties may be charged on deferred move-in costs. If a tenant fails to pay the second installment by the due date, you cannot charge a 5% late fee or daily interest. Your remedies are limited to:
- Non-renewal of the lease at expiration
- Eviction for breach of lease terms (RCW 59.12.030)
Any attempt to charge even a $25 "processing fee" or 0.5% monthly interest violates the statute and exposes you to Consumer Protection Act liability.
No Bundling with Other Charges
You cannot disguise a move-in fee as an "application fee," "administrative fee," or "tenant screening fee" and then exclude it from the installment plan calculation. The statute defines move-in costs broadly, and Washington courts (and the Attorney General's office) interpret it expansively to protect tenants.
If you charge a $50 credit check fee, that is typically considered separate from move-in costs and due upfront. However, if you charge $300 for a "move-in inspection" or "administrative processing," a court may view that as a disguised move-in fee subject to the installment plan requirement.
No Conditional Approval Contingent on Installment Payment
You cannot approve a tenant's application "pending completion of installment payments" or condition lease execution on receiving the first installment. The lease must be executed and binding before the tenant is obligated to pay. Conditioning occupancy on payment is legal, but conditioning lease formation is not.
When Does the 30-Day Clock Start?
A frequent compliance mistake: landlords treat "move-in" as the date the tenant receives keys or the lease effective date. Under RCW 59.18.610, "move-in" means the date the tenant physically occupies the unit.
Example: A lease is signed on October 1 (effective date), but the tenant doesn't occupy the unit until October 15. The 30-day window for the final installment payment starts October 15, not October 1. This distinction matters if you're setting automated payment schedules.
Best practice: Include a separate document (move-in inspection report or tenant acknowledgment form) where the tenant dates their occupancy. This creates a paper trail if there's later dispute about when the clock started.
Interaction with Other Washington Rent and Fee Laws
SB 5961 exists alongside other Washington tenant protection laws. Make sure your move-in fee practice complies with all of them:
Security Deposit Limits (RCW 59.18.140)
You can charge no more than one month's rent as a security deposit. This cap is separate from any damage deposit or other prepaid fees. If monthly rent is $1,800, your security deposit cannot exceed $1,800, even on an installment plan.
Mandatory Lease Disclosures (RCW 59.18.060)
As covered in detail in our separate Washington Lease Disclosures guide, your lease must disclose several items including the move-in cost breakdown. The move-in fee installment plan fits within this broader disclosure requirement.
Last Month's Rent Practice
Washington allows landlords to collect last month's rent upfront as part of move-in costs. However, some jurisdictions (like Seattle, with SMC 14.09) have restricted this practice. Verify your local ordinance before collecting last month's rent upfront.
Penalties for Non-Compliance: What You Risk
Violations of RCW 59.18.610 are treated as unfair and deceptive acts under Washington's Consumer Protection Act (RCW 19.86). This creates significant liability:
| Violation Type | Potential Liability | Notes |
|---|---|---|
| Charging more than 1/3 upfront | $500–$2,000 per violation | Each tenant potentially = separate violation |
| Charging late fees on installments | Actual damages × 3 (treble damages) + attorney fees | No minimum; scales with severity |
| Failing to disclose terms in writing | Up to $2,000 per lease | Attorney General can also pursue enforcement |
| Disguising move-in fees as other charges | Treble damages + court costs | Fraud-adjacent; courts view skeptically |
Beyond monetary penalties, tenant lawsuits can drain your time and management bandwidth. A tenant (or tenant advocacy group) can file a class action if multiple tenants were charged the same violation.
Attorney General Enforcement: The Washington Attorney General's office has shown willingness to investigate landlord violations. In 2024, the Attorney General's tenant rights hotline logged over 1,200 calls related to move-in fees. While enforcement is complaint-driven, it signals that regulators are watching this area closely.
Practical Compliance Checklist for Self-Managing Landlords
Use this checklist before your next tenant lease signing:
- ☐ Calculate total move-in costs (security deposit + all prepaid rent/fees)
- ☐ Divide by 3 to determine maximum upfront payment (one-third)
- ☐ Draft specific lease language or separate installment agreement with exact dollar amounts and due dates
- ☐ Ensure document states clearly: "No late fees, interest, or additional charges apply to installment payments"
- ☐ Have tenant sign the lease or agreement before collecting any payment
- ☐ Document the actual move-in date in writing (e.g., move-in inspection checklist with date)
- ☐ Set payment reminder for final installment due 30 days post-move-in
- ☐ If payment is late, do not charge a late fee; assess only non-renewal or eviction options
- ☐ Keep copies of all signed agreements and payment records for at least 6 years (statute of limitations)
- ☐ Review local ordinances (Seattle, Tacoma, etc.) for additional restrictions
Interaction with LeaseBase Compliance Tools
Managing move-in fee installment compliance manually—especially across multiple units—creates errors. LeaseBase's compliance engine flags non-compliant lease language before you send it to a tenant, and our rent payment system allows you to set automatic installment schedules that track due dates separately from regular rent cycles. This separation prevents accidental mixing of installment obligations with rent payment rules, which is a common compliance trap for landlords juggling spreadsheets.
Frequently Asked Questions
Q: Can I require a tenant to pay all move-in costs upfront if they have excellent credit?
A: No. RCW 59.18.610 is mandatory, not optional. The statute applies to all tenants regardless of creditworthiness, income, or credit score. You can offer to waive the installment plan and allow a tenant to pay in full if they choose, but you cannot require it. The law is designed to protect all renters from prohibitive upfront costs.
Q: Does the installment plan requirement apply to commercial tenants or roommate situations?
A: RCW 59.18.610 applies to residential tenancies as defined in RCW 59.18.030. This includes apartments, houses, duplexes, and manufactured homes. It does not apply to purely commercial leases. However, if you rent out a single family home or duplex where one unit is occupied by a tenant and one is occupied by an owner or manager who provides services, the tenant-occupied unit is likely covered. Roommate situations where one person is the "landlord" and the other is the tenant are typically covered, but the landlord's ownership interest must be minimal.
Q: What if a tenant wants to pay the entire move-in cost upfront? Can I accept it?
A: Yes. The statute prevents you from requiring payment of more than one-third upfront, but it does not prohibit a tenant from voluntarily paying the full amount if they wish. Ensure the tenant's choice to pay in full is documented in writing (e.g., a note on the lease signed by both parties) to avoid later disputes about whether you illegally required it.
Q: If a tenant doesn't pay the final installment by day 30, can I evict immediately?
A: You can initiate eviction proceedings, but you must follow Washington's eviction timeline. Under RCW 59.12.030, you must provide a 10-day notice to cure or quit before filing for eviction. If the tenant pays within those 10 days, the eviction stops. If they don't pay and don't vacate, you can file a forcible detainer action. The total timeline (notice + court process) typically takes 30–60 days, not immediate.
Q: I offer tenants a discount if they pay all move-in costs upfront. Does that violate SB 5961?
A: This is a gray area but likely compliant if structured correctly. You can offer a voluntary incentive (e.g., "$100 discount if paid in full by signing") as long as you do not penalize tenants for using the installment plan (e.g., do not charge a "deferral fee"). The statute prohibits fees for installments, not rewards for early payment. However, document the incentive clearly in writing to avoid later claims that you disguised a mandatory upfront payment requirement.
Key Takeaway: Compliance is the Baseline, Not the Exception
SB 5961 is now four years old, and Washington tenants know their rights. A tenant or tenant advocacy organization can file a complaint with the Attorney General or sue under the Consumer Protection Act without expensive legal representation. The statute creates incentives for compliance: clarity in writing, no add-on fees, and a clear 30-day window.
For self-managing landlords, the path to compliance is straightforward: (1) calculate total move-in costs, (2) set the maximum upfront payment at one-third, (3) document the full schedule in writing before the tenant signs, (4) do not charge late fees, and (5) track the actual move-in date.
If you manage multiple units or multiple lease cycles annually, manual tracking introduces risk. Automating move-in cost calculations and installment payment schedules—separate from regular rent payments—reduces errors and removes the cognitive load of remembering which tenant is on which payment plan.
