Washington State Property Management Laws and Requirements

Washington state property management laws treat renting out someone else’s property for compensation as a licensed real estate activity, and they layer on detailed rules covering written agreements, trust accounts, security deposits, tenant screening, fair housing, habitability, rent increases, and eviction. The Department of Licensing (DOL) enforces the licensing side under RCW 18.85, and the Residential Landlord-Tenant Act governs how you deal with tenants once units are occupied. Both sets of rules apply at the same time, and several have shifted meaningfully in the last few years, especially around rent caps and just-cause eviction.

Who Needs a Real Estate License

Managing rental property for someone else in Washington is a real estate brokerage service. Collecting rent, marketing vacancies, signing leases, and overseeing occupied units all require a Real Estate Broker or Managing Broker license from the DOL.¹ Every property management firm must operate under a Designated Broker, who bears ultimate responsibility for the conduct of all licensed staff.² Working without a license is a gross misdemeanor carrying a fine of up to $5,000, up to a year in jail, or both.

Exemptions

RCW 18.85.151 carves out a handful of narrow exemptions:³

Owners renting out their own property, or doing so for a spouse, child, or parent.
Resident on-site managers working for the landlord or the landlord’s managing agent.
Someone assisting a landlord who owns or manages no more than four residential units.
Receivers, trustees, personal representatives, executors, and guardians acting under court authority.
A person operating under a power of attorney granted by the property owner.

These exemptions are narrower than most people assume. If you manage units for multiple unrelated owners and take compensation for it, you almost certainly need a license regardless of how small the portfolio is.

The Written Management Agreement

Before a manager performs any services or collects any fees, Washington requires a written property management agreement signed by both the firm and the property owner.⁴ An oral arrangement does not satisfy the statute. At minimum the agreement must address:

How the firm is compensated (flat fee, percentage of rent, or another structure).
The type and frequency of status reports to the owner.
How client funds will be handled, deposited, and accounted for.
Whether the manager may hire, supervise, and pay employees or contractors on the owner’s behalf.
The specific scope of the manager’s authority.
The terms under which either party can terminate the relationship.

Any amendment must also be in writing and signed by both parties. Verbal changes are essentially unenforceable, which is where a lot of manager-owner disputes start.

Trust Accounts and Client Funds

Business operating money and client money never mix. Every firm receiving funds in a property management transaction must maintain a separate trust account at a Washington financial institution. The designated broker has to prepare a monthly trial balance of all client ledgers and reconcile it against both the bank statement and the check register; the checkbook balance, the bank reconciliation, and the client ledgers must agree at all times.⁵

Security deposits cannot be released to the owner or anyone else without the tenant’s written consent until the tenancy ends. Property management trust accounts are not required to bear interest, but if the written agreement directs it, an interest-bearing account can be set up for a particular owner’s funds. In that case all interest belongs to the owner, not the firm.⁶

Security Deposit Handling

All security deposits must sit in a trust account at a financial institution or licensed escrow agent in Washington. The tenant must receive a written receipt and written notice of the name, address, and location of the institution holding the money.⁷ Unless the parties agree otherwise in writing, interest earned on the deposit belongs to the landlord.

Once a tenant moves out, the manager has 30 days to either return the full deposit or provide a detailed written statement explaining what was kept and why. Missing the 30-day window forfeits any right to retain a portion of the deposit and makes the landlord liable for the full amount. If the failure was intentional, a court can award up to double the deposit plus attorney’s fees.⁸

Move-In Installments and Holding Fees

Tenants have the right to pay deposits, nonrefundable fees, and last month’s rent in installments. For tenancies of three months or longer, the tenant can split those charges into three equal monthly payments starting at the beginning of the tenancy. For shorter tenancies, two installments are allowed. No interest or extra fee may be charged for paying by installment, and refusing a written installment request costs the landlord one month’s rent plus attorney’s fees. A separate holding fee to reserve a unit before move-in cannot exceed 25 percent of the first month’s rent.⁹

Tenant Screening

Before charging a screening fee, the manager must give the applicant a written notice disclosing the name and address of the screening agency, the types of information that will be accessed, and the total fee.¹⁰ The fee cannot exceed the actual cost of the screening service.

If the manager rejects the applicant based on screening results, an adverse action notice has to go out in writing. It must include the name, address, and phone number of the reporting agency, a statement that the agency did not make the rejection decision, and an explanation of the applicant’s right to a free copy of the report and to dispute inaccuracies.¹⁰ Both state law and the federal Fair Credit Reporting Act drive this requirement.

Applicants can also present a comprehensive reusable tenant screening report and skip the screening fee entirely. To qualify, the report must have been prepared by a consumer reporting agency at the applicant’s request, include a credit report, criminal background check, and eviction history, and be no more than 30 days old. A manager who charges a screening fee anyway is liable for the fee plus up to $100, court costs, and attorney’s fees.¹⁰ The pre-screening written notice must also state whether the landlord accepts portable reports.

Fair Housing Protected Classes

Washington’s Law Against Discrimination reaches further than the federal Fair Housing Act. On top of the federal protected classes of race, color, national origin, religion, sex, familial status, and disability, Washington also prohibits housing discrimination based on:¹¹

Marital status.
Sexual orientation.
Gender expression or gender identity.
Citizenship or immigration status.
Honorably discharged veteran or military status.
Use of a trained guide dog or service animal.

The rules apply to advertising, screening, leasing, and every other stage of the operation. A facially neutral screening criterion or property rule can still violate the law if it disproportionately affects a protected class. Assistance animal requests draw particular scrutiny: reasonable accommodations override no-pet policies and breed or weight restrictions for service and emotional support animals, and pet rent, pet deposits, or extra insurance cannot be charged for them. The tenant remains liable for any damage the animal causes.

Habitability and Repairs

The Residential Landlord-Tenant Act imposes ongoing habitability duties that cannot be waived in a lease:¹²

Roofs, floors, walls, chimneys, foundations, and other structural components in reasonably good repair.
Electrical, plumbing, heating, and other landlord-supplied facilities in reasonably good working order.
Adequate facilities to supply heat, water, and hot water as reasonably needed.
A reasonable pest control program at the start of the tenancy, and continuing control in multi-unit buildings unless the tenant caused the infestation.
Substantial compliance with any building, housing, or health code whose violation would endanger tenant health or safety.

Tenants who face unresolved habitability problems have several remedies, including repair-and-deduct after written notice. Response timelines scale with severity: 24 hours for conditions that threaten life or cut off heat or water, 72 hours for other major repairs, and up to 10 days for less urgent issues. The landlord has no duty to fix conditions the tenant caused, and a tenant who unreasonably blocks access for repairs cannot later claim a habitability violation.¹²

Rent Increases and Late Fees

Under HB 1217, effective in 2025, a landlord cannot raise rent at all during the first 12 months of a tenancy. After that first year, annual increases are capped at 7 percent plus the Consumer Price Index, or 10 percent, whichever is lower. The Washington Department of Commerce has published a maximum allowable rent increase of 9.683 percent for 2026 for properties covered by the Residential Landlord-Tenant Act.¹³

Late fees run on separate rules. No late fee can be charged on rent paid within five days of the due date. If rent runs more than five days late, the landlord can then charge late fees retroactively to the first day after the due date.¹⁴ Accounting systems need to reflect the five-day grace period; a lease clause charging a fee on day two or three does not override the statute.

Just-Cause Eviction and Notice Periods

Washington is a just-cause eviction state for month-to-month and other periodic tenancies. The landlord cannot end the tenancy simply because they want the tenant out. Permitted grounds each carry their own notice period:¹⁵

Nonpayment of rent: 14-day written notice to pay or vacate.
Non-monetary lease violation: 10-day written notice to cure or vacate.
Waste, nuisance, or unlawful activity: 3-day written notice to vacate.
Owner move-in or sale to an owner-occupant: 90 days’ advance written notice.
Substantial rehabilitation, demolition, or conversion to non-residential use: 120 days’ advance written notice.

The notice must state the specific facts supporting the reason. Vague or conclusory notices invite dismissal in court. Service is by personal delivery, by leaving a copy with someone of suitable age at the premises and mailing a copy, or as a last resort by posting the notice conspicuously and mailing a copy.¹⁶

If the tenant does not comply, the landlord files an unlawful detainer action in court. Self-help evictions, like changing locks or shutting off utilities, are illegal. Courts examine whether the notice was properly served, whether the stated cause is one the statute recognizes, and whether the timelines were met to the day.

Retaliation and the 90-Day Presumption

Retaliating against a tenant for exercising legal rights is prohibited. Protected activities include filing complaints with government agencies about unsafe conditions, requesting repairs, joining a tenant organization, and reporting fair housing violations. If the landlord takes an adverse action such as raising rent, reducing services, or moving to evict within 90 days of a protected activity, the law presumes the action is retaliatory, and the landlord then carries the burden of proving a legitimate, non-retaliatory reason.

This trips managers up more often than expected. A repair request lands in March, an unrelated market-based rent increase notice goes out in April, and the manager is suddenly defending a retaliation claim from the wrong side of the burden. Documenting an independent business reason for any action taken near protected tenant activity is the only reliable defense.

Record-Keeping

Any property manager providing services for others must keep records sufficient to identify all transactions and funds handled for at least three years.¹⁷ That includes signed management agreements, lease documents, financial ledgers, trust account reconciliations, and correspondence about the properties under management. Records must be available for DOL inspection during an audit or investigation. The three-year clock runs from the date of the last entry on a transaction, not from the date the agreement was signed. Many firms hold records longer for liability reasons, since deposit disputes and owner accounting complaints often surface well after the formal relationship ends.
