HB 3071

This bill modifies Missouri's disclosure requirements for properties contaminated with radioactive or hazardous materials by expanding the definition of "knowledge" that triggers mandatory disclosure from requiring an affirmative report to including any written or electronic communication from a government agency about contamination. The legislation adds new requirements that property owners must disclose any government requests to test for contamination, grants tenants the right to terminate leases without penalty if they discover undisclosed contamination, and mandates that state agencies notify current residents within 30 days if they become aware of contamination at residential properties. Failure to make required disclosures when an owner has knowledge of contamination remains a class A misdemeanor, strengthening protections for tenants and buyers against exposure to hazardous living conditions.
