Bill > HB3071

This bill modifies existing law to require property owners, sellers, or landlords to disclose in writing to potential or current renters, buyers, or transferees if the property is or was contaminated with radioactive or other hazardous material, provided the owner has empirically supported knowledge of such contamination. "Knowledge" is defined as receiving a written or electronic communication from a governmental agency confirming the contamination. Failure to disclose when possessing such knowledge constitutes a class A misdemeanor. The bill also grants current lessees the right to terminate their lease without penalty if they discover the owner knew of contamination and failed to disclose it, under specific lease conditions. Additionally, if a governmental agency requests a right of entry to test for contamination, the owner must inform prospective or current tenants/buyers of this request. Finally, if a state agency becomes aware of radioactive or hazardous material contamination at a residential property, it must notify the current resident in writing within thirty days.
