CT HB05227

Beginning January 1, 2027, persons performing mold remediation for compensation in Connecticut must hold a certificate of registration from the Department of Consumer Protection, with proof of certification from the Institute of Inspection Cleaning and Restoration Certification, National Organization of Remediators and Microbial Inspectors, or other commissioner-approved organization

Registered contractors already certified under Chapter 400 (Home Improvement Act) are exempt from the separate mold remediation registration requirement, but must still provide evidence of mold remediation certification to obtain their contractor certificate

All mold remediation must be performed in accordance with the ANSI/IICRC S520 "Standard for Professional Mold Remediation" or any commissioner-approved successor standard

The Department of Consumer Protection must conduct an ongoing public awareness campaign beginning February 1, 2027 about indoor mold health dangers, and conduct comprehensive technology reviews every five years

Violations constitute unfair or deceptive trade practices under Connecticut consumer protection law, with the act taking effect October 1, 2026
