State guide
Washington
Washington has the most developed official meth-property framework of the three states here: local health officers declare properties unfit, state law requires certified decontamination contractors, and the Department of Health publishes a current certified-contractor list. I found current local meth-property list pages for Tacoma-Pierce County and King County, but I did not find a current public statewide contaminated-property registry page run by DOH.
Checked against official sources on October 4, 2026. Rules and links change; confirm with the office listed before you act.
- Contaminated property list
- Washington law says local health officers report contaminated properties to DOH and the department may make a contaminated-properties list available, but I did not find a current public statewide DOH meth-property registry page; local lists are published by some health departments.
- Seller and landlord disclosure
- For sales of improved residential real property, RCW 64.06.020’s disclosure statement asks whether the property has been used as an illegal drug manufacturing site; I did not find a separate statewide landlord meth-disclosure statute, but law enforcement must notify landlords of drug seizures under RCW 59.18.075/69.41.062.
- Cleanup standard
- 1.5 micrograms per 100 square centimeters of methamphetamine.
- Certified decontamination contractors
- Official page →
- State program
- Washington State Department of Health, Drug Lab Cleanup Program; local health officers/health departments administer contaminated-property orders and reuse determinations
