Essential Roommate Agreement Clauses for Washington Tenants

When living with roommates in Washington, a clear roommate agreement can prevent misunderstandings and help everyone understand their rights and responsibilities. Unlike a lease, a roommate agreement is a contract between co-tenants or occupants, spelling out how you’ll share rent, utilities, chores, and other matters. While Washington law doesn’t require roommate agreements, having one gives you peace of mind should issues arise.

Why You Need a Roommate Agreement in Washington

Sharing a rental home can be rewarding, but conflicts sometimes happen—especially about money, chores, or guests. A written roommate agreement helps clarify expectations, offers a backup if disputes arise, and makes it easier to show proof if you end up in court or need support from your landlord.

Must-Have Clauses for Your Roommate Agreement

Your agreement should be in writing, signed, and dated by everyone involved. The following are common clauses every Washington tenant should consider including:

• Names of all roommates: List all people who live in the rental unit.
• Lease terms: Start and end dates; clarify if everyone’s on the master lease or some are subtenants.
• Rent responsibility: State how much each roommate pays, when, and the payment method. Decide who pays the landlord versus who reimburses other roommates.
• Security deposit: How much did each roommate contribute? Who gets what back? How is damage handled?
• Utilities and bills: How will you split bills for power, internet, water, etc.? Who’s responsible for paying each?
• Cleaning and chores: Outline how you’ll share cleaning tasks, trash removal, and communal space upkeep.
• Guests and overnight stays: Are guests allowed? For how long? Do they need to be approved by everyone?
• Noises and quiet hours: Set guidelines for noise, especially if anyone works early or late hours.
• Pets: Are pets allowed? If so, who is responsible for them and any related costs?
• Conflict resolution: Include steps you’ll take if there’s a disagreement, such as a house meeting or outside mediation.
• Move-out procedure: What happens if someone wants to leave early? How will you find a replacement or handle lost rent?

Roommate Agreements vs. Lease Agreements

Roommate agreements are separate from official lease agreements signed with your landlord. Remember:

• All tenants on the lease are usually jointly responsible for the rental—if one person doesn’t pay, all can be held liable under the Washington Residential Landlord-Tenant Act¹.
• Roommates not on the lease (subtenants) have fewer protections. It’s important to check your lease and get landlord permission before subletting. See the WA Attorney General Tenant Resources for details.

What Washington Law Says About Shared Housing

Washington law does not govern how you split rent or assign chores among roommates, but it does protect all tenants against unlawful eviction and ensures your landlord follows proper procedures as outlined in the Residential Landlord-Tenant Act (RCW 59.18).¹

Official Forms You Might Use

• Notice of Intent to Move Out: While there is no state-mandated roommate-specific form, tenants can use a Notice of Intent to Move Out to inform roommates (and the landlord) about plans to leave. For example, if you decide to move before the lease ends, written notice helps you avoid rent disputes later.
• Change of Roommates (Add/Delete Resident): Check with your landlord or property manager—many have their own forms, such as an "Addendum to Lease" or "Roommate Change Addendum." You can request a copy directly or see examples on the WA Attorney General’s Landlord-Tenant page.

The Tribunal for Rental Disputes in Washington

In Washington, the superior court in your county handles formal rental disputes, including those between roommates if monetary damages or eviction actions are involved. You can learn more from the Washington Courts’ official website.

Action Steps for Drafting and Using a Roommate Agreement

• Meet with all roommates to discuss expectations and draft your agreement together.
• Write down all terms and have everyone review and sign the document.
• Keep a copy for each roommate. If you add or change roommates, update your agreement and notify your landlord if required by your lease.

Taking these steps early can help reduce future disputes, confusion, or costly legal issues.

FAQs About Roommate Agreements and Shared Housing in Washington

1. Are roommate agreements legally binding in Washington?
   Yes, a written and signed roommate agreement is a legally binding contract between roommates. However, it does not change your obligations under your main lease or state law.
2. Can my roommate evict me from our shared apartment?
   No, only the landlord can formally evict someone. Roommate disputes may lead to a civil lawsuit, but only the landlord can perform a legal eviction according to the Residential Landlord-Tenant Act.²
3. What if my roommate stops paying their share of rent?
   If you’re both on the lease, the landlord can hold all tenants responsible for the full rent. Try to resolve the issue together and consult your agreement; you may need to seek mediation or legal advice if the dispute continues.
4. Do all roommates need to be on the lease?
   Not necessarily. Some tenants are approved subtenants, but anyone not on the lease has fewer rights and can be asked to leave by either the main tenant or landlord, subject to proper notice.
5. Can I use a roommate agreement form from another state?
   It’s best to use a form designed for Washington or draft your own, since laws vary. Refer to the WA Attorney General's Tenant Resources for sample templates.
