Do you need a license to be a carpenter in Connecticut?
No. Connecticut doesn't license carpenters as a trade. Contractors must register with CT Dept of Consumer Protection.
State registration · By ChiselJobs Team · Updated
In short
Connecticut does not license carpenters, but contractors register with the Department of Consumer Protection depending on the work. Home improvement jobs over $200 need a Home Improvement Contractor registration, new homes need a New Home Construction Contractor registration, and large commercial work needs a Major Contractor registration. There is no exam. Registrations renew every year: the home improvement registration costs $220 a year, the new home registration $360 including the guaranty fund, and a major contractor renewal $500. Home improvement and new home contractors must carry at least $20,000 in general liability insurance. The state uses the 2021 IRC and IBC with state amendments, and the Connecticut Department of Labor runs apprenticeship.
