MO HB3071

Requires property owners, sellers, and landlords to disclose in writing to lessees, purchasers, or transferees if premises are or were contaminated with radioactive or hazardous material, provided they have empirically supported knowledge of such contamination

Expands the definition of "knowledge" from requiring a formal report to include any written or electronic communication from a governmental agency confirming contamination

Grants lessees the right to terminate their lease at no cost if they discover the owner/landlord knew about contamination and failed to disclose it

Requires property owners to disclose to tenants or buyers when a governmental agency requests a signed right of entry to test for radioactive or hazardous material contamination

Mandates state agencies notify current residents in writing within 30 days if they have knowledge of radioactive or hazardous waste contamination at residential property; failure to disclose known contamination constitutes a Class A misdemeanor
