Connecticut Contractor License Lookup

About Connecticut contractor licensing

Connecticut uses the Department of Consumer Protection's eLicense system to verify many contractor and home improvement credentials. For homeowners, the advantage is that the state offers a centralized lookup for registrations and licenses that would otherwise be hard to distinguish, especially on remodeling and specialty-trade jobs.

How licensing works in Connecticut

Connecticut relies on statewide regulation for many home improvement and trade categories. Depending on the work, the contractor may hold a registration, a trade license, or both. That distinction matters because a home improvement registration is not the same thing as an electrical, plumbing, or HVAC credential. Homeowners should verify the general home improvement authority and then separately check any trade licenses tied to the proposal.

What to verify in Connecticut

Use the DCP verification portal to search by business name, individual name, or credential number. Confirm the credential is active and review the credential type so you know whether you are looking at a home improvement registration or a licensed trade. Compare the legal name and address to the contract exactly. If the job includes major mechanical or electrical work, verify those trades separately in the same state system.

State-specific tips

• › Ask the contractor which Connecticut credential covers the contract: home improvement registration, trade license, or both.
• › Do not assume a salesperson's card proves the company is properly registered; verify the business entity itself.
• › For basement finishing and additions, check whether the proposal includes trade work that needs separate licensed professionals.
• › If the company uses a parent brand and a local subsidiary, make sure the subsidiary on your contract is the one in DCP records.
• › Use the state lookup before paying a deposit, not after the contract is already signed.
