Connecticut Contractor Bond— Which Type Do You Actually Need?
Connecticut does not issue a single "general contractor license." The state regulates contractors through three separate DCP registration programs -- each with different bonding requirements. Home improvement contractors need a $15,000 surety bond. New home builders pay into a guaranty fund instead. Major contractors have no state bond requirement at all. Out-of-state contractors face a separate DRS tax bond.
Most websites get this wrong by conflating these programs. Below is the accurate breakdown, verified against current Connecticut General Statutes and DCP regulations. For a general overview of contractor license bond requirements by state, see our comprehensive guide.

Official Connecticut Requirements
"No home improvement contractor shall engage in the business of home improvement unless such contractor has been registered with the Commissioner of Consumer Protection and has filed a surety bond in the penal sum of fifteen thousand dollars."Connecticut Department of Consumer Protection (DCP) • Connecticut General Statutes Section 20-420 and 20-426a (Chapter 400)
The Four-Registration System Most Contractors Get Wrong
The single biggest mistake contractors and competitors make is treating Connecticut as a one-bond state. The DCP administers three distinct registration programs, and a fourth bond type applies to out-of-state contractors through DRS.
Connecticut Contractor Registration and Bonding Comparison
Four contractor types, three different bonding mechanisms (CGS Chapters 399a and 400; CGS 12-430)
| Contractor Type | Regulating Agency | Bond / Fund | Amount | Statute |
|---|---|---|---|---|
| Home Improvement (HIC) | DCP | Surety Bond | $15,000 | CGS 20-426a |
| New Home Construction (NHC) | DCP | Guaranty Fund | $120-$480 fee | CGS 20-417b |
| Major Contractor | DCP | None Required | N/A | CGS 20-341 |
| Nonresident (Tax Bond) | DRS | Surety Bond | 5% of contract | CGS 12-430(7) |
NHC contractors pay into the New Home Construction Guaranty Fund -- they do NOT file a $15,000 surety bond. Many sources incorrectly state otherwise.

Get Your Free QuoteNew Home Construction Contractors: No Bond Required
This is where most sources get it wrong. If you build new residential dwellings in Connecticut, you register under Chapter 399a (CGS Section 20-417b), not Chapter 400. New home construction (NHC) contractors do not file a $15,000 surety bond. Instead, they pay into the New Home Construction Guaranty Fund, which reimburses consumers up to $30,000 for defective work or contract breaches.
Multiple competitor websites and online directories incorrectly state that NHC contractors must file a $15,000 surety bond. This is factually wrong. The $15,000 bond applies only to home improvement contractors under Chapter 400. NHC contractors under Chapter 399a pay into the guaranty fund. Verify this directly with Connecticut DCP's NHC registration page.
Major Contractors: No State Bond
Connecticut's major contractor registration covers commercial and industrial construction work. Unlike HIC registration, major contractors have no surety bond requirement at the state level. The registration process focuses on financial capability and track record instead.
While major contractors skip the state-level bond, they may still need bonds for specific public works projects under Connecticut's Little Miller Act (CGS Section 49-41), which requires payment and performance bonds on state-funded construction. Vehicle dealers operating in Connecticut also need a separate Connecticut auto dealer bond through the DMV. Contractors licensed in neighboring Massachusetts face different registration requirements through the OCABR. Learn more about contractor license bonds by state to compare how other states handle commercial contractors.
Contractors registered with CT DRS for 3+ years may file Form AU-961 instead of the standard AU-960, qualifying for a reduced bonding requirement. See CT DRS Special Notice SN 2005-12 for details.

Who Is Exempt from the HIC Bond?
Several categories of workers are exempt from home improvement contractor registration and bonding
State-licensed electricians, plumbers, and other specialty professionals working exclusively within the scope of their trade license are exempt from HIC registration and the $15,000 bond requirement.
Employees of federal, state, or local government agencies performing home improvement work in their official capacity are not required to register as HICs or file a bond.
Instructors at accredited vocational schools performing work as part of an educational program are exempt from HIC registration requirements.
If you are unsure whether you qualify for an exemption, contact Connecticut DCP at (860) 713-6000.
Disciplinary Bond Provisions
Under CGS Section 20-422, the DCP Commissioner has authority to require a surety bond as a condition for registration renewal or reinstatement for contractors who have faced disciplinary action. This disciplinary bond is separate from and in addition to the standard $15,000 HIC bond. The amount is set at the Commissioner's discretion based on the nature and severity of the violation.
If you need a disciplinary bond to reinstate your Connecticut contractor registration, we can help. These bonds require specialized underwriting. Contact us for a custom quote.
Municipal Contractor Bonds in Connecticut
Beyond state requirements, many Connecticut municipalities impose their own bonding requirements for local contractor permits
Municipal bond amounts and requirements vary. Always confirm with the local building department before beginning work in a new jurisdiction.
Five Steps to an Active HIC Registration
Follow this process to register as a home improvement contractor with DCP. For a general overview, see our how to get a surety bond guide.
Determine Your Registration Type
Confirm you need HIC registration (work on existing 1-4 family homes). If you build new homes, you need NHC registration instead (no bond). If you do commercial/industrial work, you need major contractor registration (no bond).
Purchase Your $15,000 Surety Bond
Apply for your HIC bond through a licensed surety provider. Most contractors with reasonable credit get approved within 24 hours. The bond must name the State of Connecticut as obligee.
Obtain General Liability Insurance
Secure at least $20,000 in general liability insurance from an admitted carrier. DCP requires proof of both the bond and insurance before approving registration.
Submit DCP Application
File your registration application with the DCP License Services Division along with your bond, insurance certificate, and $220 fee. Legal entities must also include a Certificate of Good Standing from the CT Secretary of State.
Maintain Your Registration
HIC registration expires March 31 each year. Keep your bond and insurance current continuously -- if either lapses, DCP will suspend your registration. Your surety must notify DCP within 30 days of bond expiration or cancellation.
Under CGS Section 20-426a, a surety on a home improvement contractor bond may petition for release 12 months after the contractor ceases registration with DCP. However, the bond cannot be released if any claims are pending. This 12-month hold period protects homeowners who may discover defects after the contractor has left the industry.
If you are winding down your contracting business in Connecticut, plan for at least one additional year of bond premium beyond your last active registration period. For more information on how surety bond pricing works during wind-down periods, see our cost guide.
