If you have employees, you need workers compensation from their first day, and in practice you will also need general liability to win most jobs. Those are the two coverages that matter most. Connecticut has no single statewide contractor license, but it does make you register for home improvement or new-home work, and those registration applications ask about your insurance. Towns also want proof of workers comp before they issue a building permit.
Who this is for: Connecticut contractors and tradespeople sorting out what registration and insurance they need to work legally and to win jobs.
The short version
- Connecticut has no single general contractor license; it uses registrations run by the consumer-protection agency.
- Home improvement work and new-home building require registration, and the applications capture your insurance.
- Workers comp is required for any contractor with one or more employees, separate from any registration.
- Towns want proof of workers comp, or a signed exemption affidavit, before issuing a building permit.
- General liability is not a state mandate but is required by almost every client and general contractor.
Registration versus insurance
It helps to keep two different things straight: the registration that lets you offer certain work, and the insurance the state and your clients require. The consumer-protection agency runs a Home Improvement Contractor registration for residential remodeling and a New Home Construction Contractor registration for building and selling new homes. Those registrations capture your insurance details, and home improvement registrants also pay into a state guaranty fund that protects homeowners. But registration is not the same as coverage; workers comp comes from the Workers' Compensation Act and applies to any contractor with employees regardless of how they are registered.
| Item | What it is | Insurance angle |
|---|---|---|
| Home Improvement Contractor registration | Required for residential remodeling above the state dollar threshold | Application captures your liability insurer; registrants fund a homeowner guaranty fund |
| New Home Construction Contractor registration | Required to build and sell new homes | Application captures liability and workers comp information |
| Workers compensation | Mandatory with one or more employees | Comes from the Workers' Compensation Act, separate from registration |
| Building permit | Issued by your town for the job | Town wants proof of workers comp, or a signed exemption affidavit |
Why workers comp is the one you cannot skip
Of everything on the list, workers comp is the hard requirement for a contractor with a crew. It is mandatory under Chapter 568 from your first employee, and Connecticut watches construction closely. Towns require proof of coverage, or a signed exemption affidavit if you truly have no employees to cover, before they will issue a building permit, so a lapse can stall your job before it starts. And because a general contractor can be made to answer for an uninsured subcontractor's injured workers, the builders you want to work for will insist on seeing your certificate.
The coverage clients actually ask for
Beyond the state's rules, your contracts drive what you carry. General contractors, developers, and commercial clients almost always require general liability and proof of workers comp before they let you on site, and many want to be named on your liability policy. General liability is not a Connecticut mandate, but in practice it is the ticket onto most jobs. A contractor who carries both, and can produce certificates quickly, wins work that an uninsured competitor cannot.
A Connecticut remodeler example
Illustrative, not a quote. A Bristol remodeling contractor registers as a Home Improvement Contractor to do residential work and hires two carpenters. The registration application asks for his insurance, and because he has employees, Connecticut requires workers comp from their first day. When he pulls a permit for a kitchen addition, the town asks for proof of coverage, which he already has, and a general contractor on a larger job asks for both his liability certificate and his workers comp certificate before letting his crew on site.

Real questions Connecticut owners ask
Does Connecticut require a contractor license with insurance?
Connecticut has no single statewide contractor license, but it requires registration for home improvement and new-home work, and those applications capture your insurance. Workers comp is required separately if you have employees.
Do I need workers comp to get a building permit in Connecticut?
Effectively yes if you have employees. Towns want proof of workers comp coverage, or a signed exemption affidavit if you truly have no employees, before they will issue a building permit for the job.
What is the difference between registration and workers comp?
Registration lets you legally offer home improvement or new-home work and captures your insurance details. Workers comp is a separate legal duty under the Workers' Compensation Act for any contractor with employees.
Is general liability insurance required for Connecticut contractors?
Not by the state for most work, but almost every general contractor, developer, and commercial client requires it before letting you on site, so in practice you need it to win jobs.
Do I need workers comp if I am a solo contractor with no employees?
Not on yourself by default, but a general contractor will usually still want a certificate. Many solo contractors carry a low-payroll policy so they can show proof of coverage and get on the job.
Why does the general contractor want my workers comp certificate?
Because a general contractor can be held responsible for an uninsured subcontractor's injured workers in Connecticut. Requiring your certificate is how they protect themselves from your potential gap.
What insurance does the New Home Construction registration ask about?
The new-home builder registration application captures your liability insurer and your workers comp information where it applies, on top of the workers comp you must carry if you have employees.
Why Connecticut owners choose Morrow
- We shop the right market for you. In Connecticut you buy workers' comp on the open, competitive market from any private insurer licensed in the state, because there is no state fund, and if no carrier will take you the NCCI-run assigned risk plan is the guaranteed backstop, so we can shop your rate freely and still have a fallback for hard-to-place work.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
