Washington Property Disclosure Laws

Death, biohazard, and meth contamination disclosure rules for Washington real estate and rentals — for sellers, buyers, and landlords.

Death disclosure
Not required
Time window
N/A
Meth disclosure
Required
Suicide addressed in statute
No
Stigma safe harbor
Yes
Primary statute
Wash. Rev. Code § 64.06

For Sellers

Washington Form 17 seller disclosure covers physical condition only. Deaths, crimes, and other stigma events are not material facts under Washington law.

Statute: Wash. Rev. Code § 64.06

  1. Check your state seller disclosure form — answer every question truthfully, even if the specific event is not listed.
  2. When in doubt, disclose in writing. Nondisclosure claims are harder to defend than disclosure complaints.
  3. Consult a licensed real estate attorney in your state before listing if a biohazard event occurred on the property.

For Buyers

Remedy standard: Form 17 seller disclosure statement. Stigma-only claims are generally barred in Washington, but sellers must answer truthfully if asked in writing — lies in response to a direct question are actionable fraud in every state.

  1. Ask the seller in writing whether any death, crime, meth activity, or biohazard event has occurred on the property.
  2. Order a professional inspection and, if suspicious, request meth residue testing or environmental screening.
  3. Search local news archives and the address on public record databases before closing.

For Landlords

Death disclosure to tenants: Not required. Biohazard/meth disclosure: Required as a habitability matter. Bedbug disclosure: Not required by state law. Federal lead paint disclosure applies to pre-1978 housing in all states.

  1. Review your state landlord-tenant act for disclosure obligations before advertising the unit.
  2. Keep written documentation of any remediation performed, including certificates from licensed biohazard contractors.
  3. When a prospective tenant asks about a past incident, answer truthfully — silence in response to a direct question can be actionable.

Meth Contamination Rules

Washington has comprehensive meth cleanup law — contaminated properties are posted by local health officers and must be decontaminated to 1.5 µg/100 cm² (raised from 0.1 in 2015) by certified contractors.
