Does a home improvement contractor need a license or registration in Connecticut?
Yes, a registration. In Connecticut, anyone who owns a home improvement business, or offers or agrees to perform home improvements, must hold a certificate of registration from the Department of Consumer Protection, unless all of their home improvement contracts together come to no more than $1,000 in any twelve months. A registered contractor must show the certificate on request and state the registration and its number in every advertisement; working without one can bring a civil penalty of up to $1,500 per violation. A licensed tradesperson doing only the work of that license is exempt. This is Conn. Gen. Stat. §§ 20-419, 20-420, 20-427, 20-428.
