FAQ
Does Connecticut require a general business license?
Connecticut doesn't have a single statewide general business license. Requirements come from industry-specific state agencies and municipal offices.
Do I need the HIC registration for construction?
If you perform home improvement work in Connecticut, yes — HIC registration with the Department of Consumer Protection is mandatory. Failure to register can result in inability to enforce contracts and potential fines.
