Washington Landlord & Tenant Updated October 20, 2026 Free Word and PDF

Residential Sublease Agreement — Washington

Before you use this: Attach the complete master lease and document any required Primary Landlord consent. If taking a deposit, complete and sign the move-in checklist and give Subtenant a copy. Complete the fire-safety and smoke-detector notice below, provide state-approved indoor-mold information, and check local and housing-program requirements. For covered housing built before 1978, complete the federal lead disclosure below and provide the approved pamphlet and available records. For a lease entered into after December 31, 2026, give the flood disclosures in section 4.

This Agreement is made on [__/__/____] between [PRIMARY TENANT FULL NAME] (“Sublessor”) and [SUBTENANT FULL NAME] (“Subtenant”). The owner or primary landlord is [NAME] (“Primary Landlord”).

1. Premises, master lease, and authorization

Address: [STREET, UNIT, CITY, WASHINGTON ZIP]. Space: ☐ Entire dwelling ☐ [ROOM/AREA] with shared use of [COMMON AREAS]. Master lease dated: [__/__/____]. Master lease term: ☐ Fixed through [__/__/____] ☐ Month to month. The complete master lease, amendments, and rules are attached as Exhibit A and delivered to Subtenant.

Master-lease subletting provision: [SECTION AND TERMS / NONE]. Authorization: ☐ Exhibit A permits this sublease without further consent. ☐ Primary Landlord's written consent is attached as Exhibit B or signed below. ☐ Required housing-program authorization is attached as Exhibit B. Subtenant will not occupy until all required authorization is documented. Sublessor remains responsible under the master lease unless Primary Landlord separately releases Sublessor in writing.

2. Term, rent, and charges

This sublease begins [__/__/____] and has a stated end date of [__/__/____], no later than Sublessor's lawful right to possession under the master lease. Any extension requires a signed writing and any required Primary Landlord authorization. The stated end date alone does not establish a right to remove Subtenant. Washington's RCW 59.18.650 limits when a landlord can end a fixed-term tenancy or refuse its continuation; some fixed-term tenancies become month to month. Any end-of-term notice, continued occupancy, or possession action must follow that section and the master lease.

Rent: $[____] per [MONTH / OTHER PERIOD: SPECIFY]. A full monthly rent period begins on day [1-28] and ends the day before that date next month; if another period is selected, each full period runs from [START DAY/DATE] through [END DAY/DATE]. Rent is due at the start of each selected period. Pay [PAYEE] at [ADDRESS/ACCOUNT] by [METHOD]. Nonelectronic payment method: [METHOD]. First full rent period, if any: [START DATE THROUGH END DATE / NONE], at the recurring rent stated above, due [__/__/____ / NONE] (that period's starting date). Complete the schedule for any initial or final partial rent period; write "none" where a period does not apply. If the whole term fits within one partial period, complete the initial row and mark the final row and first full period "none." Each partial amount replaces recurring rent for its covered dates; do not charge the same dates twice.

Partial period Covered dates Rent and payee Due date
Initial [START DATE / NONE] through [END DATE / NONE] $[AMOUNT / NONE] to [PAYEE / NONE] [__/__/____ / NONE]
Final [START DATE / NONE] through [END DATE / NONE] $[AMOUNT / NONE] to [PAYEE / NONE] [__/__/____ / NONE]

Credit rent already paid for the initial or final covered dates against the completed amount for those dates. Sublessor will return any excess prepaid rent within 15 days after this sublease lawfully ends and Subtenant vacates. This rent settlement is separate from the deposit return in Section 3 and does not release Sublessor from the master lease.

Late charge: ☐ None ☐ $[____] if rent remains unpaid more than five days after its due date. No late charge is payable for rent paid within five days after due; an incomplete amount means no charge is agreed.

Utilities/services paid by Sublessor: [LIST]. Paid by Subtenant: [LIST AND ALLOCATION]. Other agreed charges: [ITEM, AMOUNT, DUE DATE / NONE]. Permitted occupants: [NAMES]. Pets: [TERMS / NONE]. Parking/storage: [TERMS / NONE]. Attached rules: [IDENTIFY / NONE].

3. Deposit and condition

Subtenant pays a refundable deposit of $[____ / ZERO]. If the amount is above zero, the parties will complete and sign a written move-in checklist describing the premises' condition and cleanliness at the commencement of this sublease; Subtenant receives a copy. The deposit may be withheld only on the grounds written here: unpaid rent or other agreed charges, or documented damage caused by Subtenant beyond wear resulting from ordinary use. Sublessor will promptly place the deposit in a Washington trust account, give Subtenant a deposit receipt, and give written notice of the depository's name, address, and location: [DETAILS].

Within 30 days after both termination and vacation, or within 30 days after Sublessor learns of statutory abandonment, Sublessor will personally deliver or first-class mail to Subtenant's last known address any refund and a full, specific statement of deductions with the required estimates, invoices, receipts, or other documentation. Forwarding address: [ADDRESS / TO BE PROVIDED]. No deduction will be made for wear resulting from ordinary use.

4. Care, entry, and notices

Subtenant will keep the space reasonably clean, report repairs promptly, and avoid damage beyond ordinary use. Sublessor will maintain the dwelling as applicable law requires and coordinate repairs requiring Primary Landlord's action.

For lawful inspection, repairs, services, or showing, Sublessor will request consent and ordinarily give at least two days' written notice stating the entry date and time window and a phone number for objections or rescheduling. A showing to prospective or actual purchasers or tenants may use the statute's one-day notice rule. Entry will occur at a reasonable time and will not be used to harass Subtenant. Emergency or impracticability exceptions remain subject to law.

Sublessor notice address: [DETAILS]. If Sublessor resides outside Washington, the designated agent residing in the county for service of notices and process is [NAME, COUNTY, ADDRESS]. Primary Landlord notice address: [DETAILS]. Subtenant notice address: [DWELLING / OTHER]. The parties will promptly share notices from Primary Landlord that affect this sublease. At lawful termination, Subtenant will vacate, remove personal property, return keys to [PERSON], leave the dwelling reasonably clean subject to ordinary use, and provide a forwarding address. No provision authorizes self-help removal.

Flood disclosure for leases entered after December 31, 2026: The property may be located in a special flood hazard area or an area of potential flooding. Sublessor's insurance does not cover loss of Subtenant's personal possessions. Subtenant should consider renter's insurance and flood insurance for losses due to fire, flood, or other risks. Information about hazards affecting the property, including flood risk, is available from the county government where the property is located: [COUNTY AND COUNTY CONTACT OR WEBSITE].

  • Exhibit A: Complete master lease, amendments, and rules: ☐ Attached and delivered.
  • Exhibit B: Primary Landlord and program authorization: ☐ Attached ☐ Signed below.
  • Signed move-in condition checklist with Subtenant's copy: ☐ Attached.
  • Signed fire-safety and smoke-detector notice, plus approved mold information: ☐ Delivered as Exhibit C below.

  • Applicable local, federal, or program disclosures: [IDENTIFY / NONE APPLICABLE].

5. Agreement and signatures

Landlord-tenant paperwork governs who can stay in a property, on what terms, and what happens when something goes wrong. Leases, notices to quit, security deposit demands, and habitability complaints all have state and often city-specific requirements for timing, content, and service. Getting the paperwork right is what makes an eviction actually succeed or a security deposit actually come back, because judges regularly dismiss cases over small procedural mistakes.
