Washington Apartment Bedbug Disclosure Laws: Renter Guide

Moving into a new apartment should be a fresh start, not a source of stress. For renters in Washington, knowing your rights about bedbug disclosures is key to protecting your health and safety. In this article, we break down what Washington law says about bedbug notifications, your landlord’s responsibilities, and what to do if you suspect bedbugs in your new home.

Bedbug Disclosure Requirements for Washington Renters

Washington has clear requirements for landlords regarding bedbug disclosures. These laws aim to ensure renters can make informed decisions and avoid the serious health and financial issues bedbugs can cause.

  • Disclosure Obligation: Landlords must provide written information about bedbug identification, prevention, and control to new tenants at or before move-in.1
  • If the unit, building, or complex has had a bedbug infestation within the past year, landlords must give you written notice of this history before you sign your rental agreement.2
  • If a landlord learns of a bedbug infestation during your tenancy, they must notify tenants in affected units promptly and provide information on the landlord's treatment plan.

Where Does This Law Come From?

Bedbug disclosure rules in Washington come from the Residential Landlord-Tenant Act (RCW 59.18), which sets the standards for rental housing health and safety.

What Information Must Landlords Give?

When you move in, your landlord must give you written materials created or approved by the Washington State Department of Health. This information helps renters:

  • Recognize signs and symptoms of bedbugs
  • Understand how to report bedbug problems
  • Learn what both tenants and landlords can do to prevent and address infestations

You can review official Department of Health resources at the Washington State Department of Health: Bedbugs page.

What Should You Do If You Find Bedbugs?

If you discover possible bedbug activity in your apartment:

  • Immediately notify your landlord in writing. It’s best to send a dated notice (email or letter saved for your records).
  • The landlord then has a legal duty to inspect and, if necessary, arrange for bedbug removal at their expense.
  • Tenants must cooperate with instructions to prepare the unit for inspection or treatment.
Always report a suspected infestation as soon as possible—early action protects your health and helps stop the spread.

Official Washington Bedbug Reporting Form

While Washington State does not have a single statewide bedbug-specific form, your landlord may provide an internal form to submit complaints. If an issue persists, you can use the standard Landlord Repair Request Notice format:

If your landlord does not respond within a "prompt" time (usually within 24-48 hours for health hazards), you may have additional remedies under state law.
