Property Management Laws And Regulations In Washington

Washington regulates third-party property management through several authorities at once, and the rules that matter most to a management company are the ones covering your license, your client trust accounts, and the money you hold on behalf of owners and tenants. This guide covers those rules for professional managers, with the statute or agency regulation behind each one.

Everything below is sourced to Washington's own statutes, agency rules, and court materials rather than to secondhand summaries. Specific dollar amounts and deadlines do change; the citations do not, so you can always open the authority and confirm the current text before you act on it.

Licensing Requirements For Property Managers

Washington requires a real estate broker or managing broker license, issued by the Department of Licensing under RCW 18.85, for persons who provide property management services for compensation, though the statute carves out several specific exemptions relevant to owners, resident managers, and limited-scope support staff.

• 'Property management services' is defined by statute to include marketing, leasing, and renting real property, and the physical, administrative, or financial maintenance of real property, or the supervision of those activities. (RCW 18.85.011)
• A person desiring a real estate broker or managing broker license must pass a licensing examination administered under rules of the Department of Licensing; real estate firms must likewise obtain a firm license. (RCW 18.85.101)
• Owners managing their own property, resident on-site managers acting for the owner or the owner's managing broker, court-appointed fiduciaries (receivers, trustees, personal representatives, guardians), and persons acting under a power of attorney from the owner are exempt from broker licensing. (RCW 18.85.151)
• A person employed or retained by an owner or a managing broker is exempt from licensing if limited to delivering or receiving lease documents, applications, or payments; showing a rental unit; or providing information about a rental unit, lease, application, or rental amount. (RCW 18.85.151(13))

Client Trust Account Rules

Washington's trust-account rules for property managers combine a statutory duty to hold client funds in trust (RCW 18.85.285) with detailed Department of Licensing administrative rules (WAC 308-124E) governing deposit timing, monthly reconciliation, and record retention, plus a notable exemption for property management trust accounts from the interest-bearing requirement that applies to sales trust accounts.

• A real estate broker who receives funds from any principal or party to a real estate transaction or property management agreement must hold those funds in trust for the purposes of the agreement or transaction, and must not use the funds for the broker's own benefit or the benefit of anyone not entitled to them. (RCW 18.85.285)
• Trust funds received must be deposited in a bank, savings association, or credit union insured by the FDIC or the NCUA share insurance fund. (RCW 18.85.285)
• Trust bank accounts used for property management transactions are exempt from the interest-bearing account requirement that otherwise applies to real estate sales trust accounts, though an interest-bearing property management trust account may still be established. (WAC 308-124E-110; WAC 308-124E-115)
• All funds received relating to the sale, renting, leasing, or optioning of real estate must be deposited in the firm's trust bank account no later than the next banking day after receipt. (WAC 308-124E-105)
• The designated broker is responsible for preparing a monthly trial balance of the client's ledger and reconciling that ledger against both the trust account bank statement and the trust account check register. (WAC 308-124E-105)
• Property management commissions held in a property management trust account must be withdrawn at least once monthly. (WAC 308-124E-115)

Trust account rules are where Washington management companies get into trouble fastest, because a shortage is a licensing problem and not just a bookkeeping problem. The Washington State Department of Licensing works from the records a broker is already required to keep, which puts trust accounting for property managers among recordkeeping obligations rather than optional hygiene. The habits that keep you clean are the boring ones: deposit on time, never let operating money and client money mix, reconcile every account every month, and keep a per, property record you could hand to an auditor without preparing it first. Our guide to preparing for a trust account audit walks through what examiners actually ask for.

Security Deposit Rules

Washington's Residential Landlord-Tenant Act requires a signed move-in condition checklist before a deposit is collected, and, as of a 2023 amendment still in effect, gives landlords 30 days after move-out to itemize and refund the deposit with supporting documentation for damage deductions.

• A landlord may not collect a security deposit or nonrefundable fee unless a written checklist or statement describing the condition and cleanliness of the premises has been provided to and signed by the tenant. (RCW 59.18.260)
• Within 30 days after termination of the rental agreement and the tenant vacating, the landlord must give a full and specific statement of the basis for retaining any of the deposit, together with any refund due, and must include supporting documentation such as receipts or paid invoices for damage-related deductions. (RCW 59.18.280)
• A landlord may not deduct for ordinary wear and tear from use, and deductions for damage must be documented and tied to conditions noted on the move-in checklist. (RCW 59.18.280)
• A landlord who fails to provide the required statement and refund within the deadline is liable for the full deposit amount, and a court may award up to two times the deposit amount for an intentional refusal to return it, plus attorney's fees and costs. (RCW 59.18.280)

Lease Agreements And Required Disclosures

Washington law requires several specific written disclosures at lease signing, including mold information and fire-safety information for multifamily buildings, and treats undisclosed nonrefundable fees as refundable deposits.

• At the time a rental agreement is signed, a landlord must provide the tenant with information about the health hazards associated with exposure to indoor mold, in a form provided or approved by the Department of Health. (RCW 59.18.060)
• A landlord of a multifamily residential building must provide new tenants, at the time the lease is signed, written notice or a checklist disclosing the building's fire safety and protection devices and systems, including a diagram of emergency evacuation routes. (RCW 59.18.060)
• A fee charged to a tenant is treated as a refundable deposit unless the rental agreement specifies in writing that the fee is nonrefundable. (RCW 59.18.260)

Entry Notice And Tenant Privacy

Washington requires two days' written notice for most nonemergency landlord entry, one day's notice to show a unit, and permits entry without notice only for emergencies.

• A landlord must give at least two days' written notice before entering the dwelling unit for agreed repairs or maintenance, services necessary to maintain the property, or inspections permitted under the lease, specifying the date, approximate time, and purpose of entry. (RCW 59.18.150)
• A landlord may enter to show the unit to prospective tenants, purchasers, workers, or contractors after giving one day's notice. (RCW 59.18.150)
• No notice is required for entry when there is a reasonably perceived emergency threatening the health or safety of a tenant or other occupant, or risking damage to the property. (RCW 59.18.150(6))

Rent, Late Fees, And Other Charges

Washington enacted a first-in-state statewide cap on rent increases in 2025 (HB 1217, codified in RCW 59.18.700-.720). After the first 12 months of a tenancy, most landlords may raise rent (and other recurring/periodic charges identified in the rental agreement) by no more than 7% plus the relevant Consumer Price Index, or 10%, whichever is less, once every 12 months, on 90 days' written notice, with a list of statutory exemptions.

• A landlord may not increase rent at all during the first 12 months of a tenancy, and thereafter may increase rent and other recurring or periodic charges identified in the rental agreement only once in any 12-month period, by no more than 7 percent plus the applicable Consumer Price Index or 10 percent, whichever is less. (RCW 59.18.700)
• A landlord must give a tenant a minimum of 90 days' prior written notice of a rent increase; for subsidized tenancies where rent is based on tenant income, the minimum notice is 30 days. (RCW 59.18.140)
• The rent-increase cap does not apply to, among other exemptions, tenancies in new construction for 12 years after the first certificate of occupancy, certain publicly owned or regulated affordable housing, federal low-income housing tax credit developments under an enforceable regulatory agreement, and specified owner-occupied properties (duplexes, triplexes, fourplexes, and shared-facility tenancies) where the owner is not a corporation, LLC, or REIT. (RCW 59.18.710)
• This rent-increase cap provision is scheduled to expire on July 1, 2040. (RCW 59.18.700)

Fee income is also taxable income, and how you record management fees, late fees, and pass, through charges affects both your compliance position and your books. See our guide to Washington property management tax deductions for the reporting side.

Fair Housing Obligations

The Washington State Human Rights Commission enforces the Washington Law Against Discrimination, which extends housing protections well beyond the federal Fair Housing Act's protected classes.

• The Washington State Human Rights Commission enforces the Washington Law Against Discrimination, including its housing provisions. (RCW 49.60)
• Washington's fair housing protections cover race, creed, color, national origin, citizenship or immigration status, families with children, sex, marital status, sexual orientation, age, honorably discharged veteran or military status, and the presence of a sensory, mental, or physical disability or use of a trained dog guide or service animal. (RCW 49.60)
• A person who believes they have been discriminated against in housing on a protected basis may file a complaint with the Washington State Human Rights Commission within one year of the alleged violation. (RCW 49.60)

Habitability And Safety Duties

Washington imposes a detailed, ongoing set of habitability duties on landlords and prohibits retaliation against tenants who exercise their rights, backed by a rebuttable presumption when adverse action follows protected activity closely in time.

• A landlord must at all times during the tenancy keep the premises fit for human habitation, including compliance with applicable codes, maintaining structural components (roofs, floors, walls, foundations) in reasonably good repair, keeping common areas clean and safe, and providing a reasonable pest-control program at the start of the tenancy. (RCW 59.18.060)
• A landlord may not take or threaten reprisals or retaliatory action against a tenant because of the tenant's good-faith complaint to a governmental authority about code violations, or because of the tenant's assertion of rights or remedies under the Residential Landlord-Tenant Act. (RCW 59.18.240)
• If a landlord takes a listed adverse action within 90 days after a tenant's good-faith protected act (or a related governmental inspection or proceeding), a rebuttable presumption arises that the action is retaliatory, subject to exceptions such as the tenant being in arrears on rent. (RCW 59.18.250)

Eviction Basics

Washington evictions proceed as unlawful detainer actions, preceded for nonpayment of rent by a statutory 14-day notice that must use the state's required form and may demand rent only, not other charges.

• For nonpayment of rent, a landlord must serve a statutory 14-day notice to pay rent or vacate; the tenant may avoid termination by paying the full amount demanded within 14 days after service. (RCW 59.18.057)
• The 14-day pay-or-vacate notice may demand only unpaid rent; late fees, damages, or other non-rent charges may not be included in that notice or used as the basis for an unlawful detainer action for nonpayment. (RCW 59.18.057)
• If the tenant does not comply with a proper notice, the landlord may commence an unlawful detainer action in superior court to obtain possession. (RCW 59.18.057; RCW 59.12)

Recent Changes Worth Tracking

These are the Washington changes most likely to affect a management company's procedures. Confirm the effective date against the source below before you update a lease template or a policy.

• Effective May 7, 2025 (immediate), provisions expire July 1, 2040: Washington enacted its first statewide cap on residential rent increases: after the first 12 months of tenancy, rent (and certain recurring charges) may be raised at most once every 12 months, by no more than 7% plus CPI or 10%, whichever is less, subject to statutory exemptions. (RCW 59.18.700-.720 (2025 c, HB 1217))
• Effective May 7, 2025: The minimum notice period for a rent increase was lengthened from 60 days to 90 days (30 days for subsidized, income-based tenancies), with a transitional 60-day rule for leases already in place when the law was signed. (RCW 59.18.140)

Staying Compliant Without Guessing

Most Washington compliance failures are not decisions, they are drift: a deposit that sat too long, a reconciliation that got skipped in a busy month, a lease template that never got updated after a statute changed. Build the calendar first. Monthly trust reconciliations, an annual review of your lease and disclosure packet against current statutes, and a documented process for deposits and refunds cover the large majority of what an examiner will ask about.

This guide is a starting point for professional managers, not legal advice. For a specific dispute, a novel fact pattern, or anything with real money at stake, work with a Washington attorney, and confirm the current text of any statute cited above with the Washington State Department of Licensing or the Washington legislature.
