Washington Renters: Your Rights When Facing Mold Problems

Mold issues in rental homes are more than just an eyesore—they can cause health concerns and threaten the quality of your living space. If you're a renter in Washington and have discovered mold in your unit, it's important to know your rights, the landlord’s responsibilities, and what steps you can take to get your home safe again under Washington law.

Understanding Mold and Your Right to a Healthy Home

Washington state law requires landlords to provide rental properties that are safe, clean, and in good repair. This "habitability" standard is protected by the Residential Landlord-Tenant Act (RLTA). Under this law, your landlord must ensure the property is kept up in a way that does not endanger your health—including fixing leaks and water problems that lead to mold.

What to Do If You Find Mold in Your Rental

If you spot mold:

  • Act quickly—mold can grow rapidly in damp or poorly ventilated areas.
  • Document the problem. Take clear photos and note the date you discovered the mold and any signs of water damage.
  • Notify your landlord in writing right away, describing where the mold is and attaching photos if possible.

Landlord Responsibilities in Washington

Your landlord is required to:

  • Maintain rental units free from hazards—this includes promptly repairing leaks and eliminating mold sources.
  • Comply with all local building and housing codes that impact health and safety.
  • Respond to written maintenance requests within required timelines (typically within 24 hours for emergencies).
Tip: Always make maintenance requests in writing and keep a copy for your records.

How to Request Repairs for Mold Problems

If the landlord does not fix the mold problem in a reasonable time after you notify them in writing, you have options:

  • Submit a written request again using Washington’s recommended format.
  • Withhold rent or pay for the repairs yourself—but only if you follow specific legal steps under the RLTA.
  • If still unresolved, you may file a complaint with your local building or health department.

Official Forms and Filing a Complaint

Notice to Landlord: Request for Repairs

  • Form Name: Washington State - Sample Tenant Repair Request Letter
  • Use this written notice to inform your landlord of the mold and request prompt repairs. Include your contact information, address, date, and details about the problem.
  • Find a sample template on the Washington State Attorney General's Landlord-Tenant Guide.

Notice of Intent to Repair and Deduct

  • Form Name: Notice of Intent to Repair and Deduct
  • You must provide written notice to your landlord as required under state law before you hire someone to fix the mold and deduct up to one month’s rent from your payment.
  • Guidance and sample language are available on the Washington Attorney General’s Tenants' Rights page.

Filing a Complaint with Local Authorities

For rent withholding and other repairs, you must follow the specific procedures in the Residential Landlord-Tenant Act (RCW 59.18) to avoid legal trouble. Washington does not have a separate residential tenancy tribunal; these disputes are usually handled in your local county court.

What to Expect After Reporting Mold

After you properly notify your landlord, they must promptly respond and begin remediation. Renters are not responsible for mold caused by faulty plumbing or building leaks. If you contributed to the problem (for example, by failing to ventilate bathrooms), you may share responsibility for any resulting damage.

If your landlord doesn't respond or retaliates after you report mold, it may be illegal. There are protections against retaliation in the RLTA.

FAQ: Mold Problems and Tenant Rights in Washington

  1. How quickly must my landlord fix mold problems?
    For dangerous conditions (severe leaks, hazardous mold), Washington law generally requires repairs within 24 hours of written notice. Non-emergency issues should be addressed within a reasonable time, such as 3–10 days, depending on the situation.
  2. Can I withhold rent until my landlord fixes mold?
    You can only withhold rent if you follow the legal steps found in the RLTA, such as providing proper notice and allowing your landlord time to respond. Make sure to read the process carefully or get legal advice first.
  3. Who is responsible for cleaning up mold in a rental?
    Landlords are responsible for fixing problems that cause mold, like leaks or broken windows. Tenants must keep their home reasonably clean and ventilated to avoid causing mold themselves.
  4. What should I do if my health is affected by mold exposure?
    If you’re experiencing health problems, see a doctor and inform your landlord in writing. You may contact your local health department for an inspection if the mold is extensive or dangerous.
  5. Is my landlord allowed to evict me for reporting mold?
    No. It is illegal for your landlord to retaliate against you—such as threatening eviction—for making a good-faith complaint about mold or repairs.

Key Takeaways for Washington Renters Facing Mold

  • Document and report mold problems to your landlord in writing as soon as possible.
  • Landlords are required by law to address health hazards—including mold—promptly.
