About this bond

What a contractor license bond is

Some states, and many cities and counties, make contractors post a bond to get or renew a license. It protects customers, workers and the public if the contractor breaks the licensing laws, for example by abandoning a job or not paying workers. The contractor repays the surety for any claim it pays.

In Connecticut

  • Registration is required for residential work on single or multifamily dwellings of six units or less, among other property types.
  • New home construction contractors register separately and must carry liability insurance of at least $20,000 (DCP guide).
  • A town can set its own bond rules for specific permits, such as street excavation.

FAQs

Common questions.

Does Connecticut require a contractor license bond?

See the facts above for what the state requires. Even where the state doesn't, a city or county can. Check with the licensing office where you'll work.

Is a license bond the same as insurance?

No. The bond protects your customers and the public, not you. If the surety pays a claim, you repay it. Liability insurance is what protects your business.

What happens if the bond lapses?

The licensing agency is notified and can suspend your license until a new bond is on file. Renew before the expiry date.

What does it cost?

You pay a premium, not the bond amount. The surety sets the premium after it reviews your application, usually as a percentage of the bond amount. We show you the terms before you commit.
