Step-by-Step: Verifying CT Contractor Registration
Go to elicense.ct.gov
This is the official CT DCP e-License portal. Do not use third-party lookup services — they may have outdated data. The DCP portal is updated in real time.
Click "License Lookup" or "Verify a License"
You don't need to create an account or log in. The lookup is public and free.
Select license type: "Home Improvement Contractor"
This is the HIC registration category under CGS § 20-420. Note: plumbers, electricians, and HVAC technicians are separately licensed — search their specific trade category.
Search by contractor or business name
Enter the name exactly as it appears on the bid or contract. If you have the registration number (should be on the contract), search by that for exact match.
Verify "Active" status
The registration must show "Active" — not expired, suspended, or revoked. An expired registration provides significantly fewer consumer protections.
Check for disciplinary actions
The record shows any complaints, violations, or disciplinary actions on file with DCP. Multiple complaints are a serious red flag even if the registration is currently active.
What CT Registration Actually Means (and Doesn't)
Registered contractor ✓
- • Can legally enforce contracts under the Home Improvement Act
- • Required to carry liability insurance
- • Must post $15,000 bond (CGS § 20-422)
- • Subject to DCP investigation and discipline
- • Victims can access the CT Home Improvement Guaranty Fund
Registration does NOT mean: ✗
- • The contractor passed any competency test
- • Their work will meet code requirements
- • They have no prior complaints (check the record)
- • Their subcontractors are registered
- • Their estimates are accurate or fair
Registration is the floor, not the ceiling. Use it as the first filter, then evaluate the bid itself on price, scope, and payment structure.
What Happens If You Hire an Unregistered Contractor
Hiring an unregistered contractor doesn't just put you at higher risk of fraud — it affects your legal rights in specific ways:
Contract may be unenforceable against the contractor
Under CGS § 20-429, home improvement contracts entered with unregistered contractors are difficult or impossible to enforce in CT courts. The contractor has less to lose by walking away.
No access to the CT Home Improvement Guaranty Fund
The fund only covers losses from registered (or recently registered) contractors. An unregistered contractor leaves you with small claims court and criminal referral as your only options.
No registration bond to claim against
Registered contractors carry a $15,000 bond under CGS § 20-422. Unregistered contractors have no bond — you're chasing an individual with no legal backstop.
Potential insurance complications
If an unregistered contractor's worker is injured on your property, your homeowner's insurance may have complications covering the claim since they weren't operating legally.
Work may fail permit inspection
Unregistered contractors often skip permits. Unpermitted work discovered during a home sale can require costly remediation and can block a closing.
