The proposed General Assembly Raised Bill No. 5227 aims to regulate mold remediation in Connecticut, with new regulations set to take effect on October 1, 2026. The bill defines essential terms such as "mold" and "mold remediation," and outlines the responsibilities of the Commissioner of Consumer Protection and the Department of Consumer Protection. Starting January 1, 2027, individuals or entities performing mold remediation for compensation must obtain a valid certificate of registration from the Department, with exceptions for contractors already certified under existing laws. The bill mandates adherence to ANSI/IICRC S520 standards and requires public awareness campaigns about the health risks of indoor mold.

Additionally, the bill introduces new requirements for contractors, including proof of certification from recognized organizations, and establishes that violations will be classified as unfair or deceptive trade practices. It also includes provisions for ongoing reviews of mold remediation technologies and mandates annual reports from the Commissioner to the General Assembly regarding indoor mold health effects and remediation standards. The bill repeals and replaces certain sections of existing law to incorporate these new regulations, ensuring a comprehensive and updated approach to mold remediation in the state.
