Licensing

Connecticut contractor license requirements

Connecticut has no single general contractor license. Residential contractors register with the Department of Consumer Protection, builders of large threshold buildings register as major contractors, and the trades carry their own occupational licenses.

Connecticut does not issue one all-purpose general contractor license. Instead, the Department of Consumer Protection (DCP) runs three registrations that cover most builders: Home Improvement Contractor for residential remodeling and repair, New Home Construction Contractor for anyone who builds or sells new homes to consumers, and Major Contractor for work on large threshold buildings. Electricians, plumbers, HVAC and sheet metal workers, and a long list of other trades need separate occupational licenses from DCP boards. A commercial general contractor working on ordinary buildings below the threshold limits generally needs no state contractor registration at all, although the trades on that job still must be licensed.

Home Improvement Contractor registration

This is the registration most small Connecticut contractors need. The Home Improvement Act (Chapter 400 of the General Statutes) defines home improvement broadly: repair, remodeling, alteration, conversion, additions, and sandblasting on any building used as a private residence or residential rental property, plus driveways, swimming pools, porches, garages, roofs, siding, insulation, sunrooms, flooring, patios, landscaping, fences, doors and windows, waterproofing, and water, fire, or storm restoration. If your residential contracts add up to more than $1,000 in any 12 consecutive months, you are a contractor under the law and must register.

  • Apply online only. DCP takes HIC applications through its eLicense system. Decide first whether you are registering as a sole proprietor or as a legal entity. An individual registration does not cover your LLC, and a legal entity must be registered with the Connecticut Secretary of the State before it applies.
  • Insurance. You need general liability insurance of no less than $20,000, and the application asks for the insurer's name and policy number.
  • Fee. The statute sets the registration fee at $120, and DCP adds $100 for the Home Improvement Guaranty Fund, for $220 total at application.
  • Background. The application asks about felony convictions, and applicants with a felony conviction complete DCP's Criminal Conviction Application Worksheet.
  • Salespeople. Anyone selling home improvement jobs on your behalf must hold a separate Home Improvement Salesperson registration.
  • Advertising. The law requires you to state in advertisements that you are registered and to include your registration number.

Licensed trades working only within their license are exempt from HIC registration, so a licensed plumber replacing a water heater does not also need an HIC. DCP's guide also notes that you do not need to register if you work only as a subcontractor for a registered home improvement contractor. The moment you contract directly with the homeowner, you need your own registration.

Home improvement contracts must follow the statute

Connecticut is strict about paperwork. Under section 20-429, a home improvement contract is not valid or enforceable against the owner unless it is in writing, signed by both the owner and the contractor, contains the entire agreement, the transaction date, your name, address, and registration number, a notice of the owner's cancellation rights, and a start date and completion date. It also must disclose other contracting businesses the owners have been involved with in the previous five years. Every change to the terms has to be in writing and signed by both sides, which means verbal change orders are a real risk in this state.

Say a kitchen remodeler signs a $62,000 job, then the homeowner asks for a $4,800 pantry addition at the walkthrough. If that change is not written up and signed before the work starts, collecting on it gets much harder. A change order template that both parties sign on the spot solves most of this.

Penalties are criminal, not just administrative. Offering or making a home improvement without a current registration is a class B misdemeanor under section 20-427, DCP can impose civil penalties after a hearing, and a violation of the chapter is treated as an unfair trade practice.

New Home Construction Contractor registration

Builders who construct or sell new homes to consumers register as New Home Construction Contractors, including on speculative housing. DCP lists the fee, effective July 1, 2022, as $360: a $120 registration fee and a $240 guaranty fund fee. If you also want to do remodeling, add the home improvement designation for another $100 guaranty fund fee rather than holding two separate registrations. The same $20,000 general liability minimum applies. DCP excludes contracts under $3,500 combined value for the same home and work done after the certificate of occupancy is issued. Like HIC registrations, NHC registrations expire every March 31 and must be renewed and paid online.

Major Contractor registration for threshold buildings

Commercial builders hit state registration only on big buildings. Under section 20-341gg, a major contractor is anyone who builds, structurally repairs, alters, dismantles, or demolishes a structure that exceeds the building code threshold limits, plus subcontractors whose work affects structural integrity on those buildings, such as roofing, masonry, and structural frame work. DCP describes a threshold building as one with at least 4 stories, 60 feet of height, a 150 foot clear span, 150,000 square feet of gross floor area, or an occupancy of 1,000 people, with extra limits for some use groups.

  • Submit the application online with two credit references: one from a supplier or subcontractor and one from a financial institution.
  • Registrations expire every June 30, and DCP lists the renewal fee as $500.
  • Contractors prequalified with the Department of Administrative Services for state work receive the registration and pay no fee while their prequalification stays valid.
  • A lapsed registration can be reinstated up to three years after it expires; after that you reapply.

Trade licenses come from separate DCP boards

DCP states plainly that people performing electrical, HVAC, plumbing, heating, and similar jobs must have the appropriate Connecticut license. Its list of occupational licenses includes electrical, plumbing, heating, piping and cooling, sheet metal and ductwork, fire protection, elevator, crane, glass, solar, irrigation, spa and pool, well drilling, and several others. Each board publishes a testing bulletin with the scope of each license level. If you run a general contracting firm, the practical question is which of your subs hold which license, and whether those licenses are current on the day they work. Tracking that alongside each sub's insurance certificate is what subcontractor compliance automation is built for.

How to look up a Connecticut contractor

Use DCP's eLicense system at elicense.ct.gov to verify a home improvement, new home construction, major contractor, or trade license. Results show whether an NHC holder has added the home improvement designation. Homeowners have a strong reason to check: the Home Improvement Guaranty Fund can reimburse up to $25,000 for a job done by a contractor who was registered, but only if the contractor was registered at the right time. Before you bid public work, also read the Connecticut prevailing wage rules and the Connecticut mechanics lien deadlines.

Frequently asked questions

Does Connecticut have a general contractor license?

No. Connecticut has no single general contractor license. Residential contractors register as Home Improvement or New Home Construction Contractors, builders on large threshold buildings register as Major Contractors, and trades such as electrical and plumbing hold DCP occupational licenses.

How much does a Connecticut home improvement registration cost?

DCP lists a non-refundable $220 application fee. That is the $120 registration fee set by statute plus $100 that goes to the Home Improvement Guaranty Fund. You also need at least $20,000 of general liability insurance.

Is there an exam for Connecticut home improvement registration?

No exam appears in DCP's home improvement or new home construction application requirements. The occupational trade licenses, such as electrical and plumbing, do involve exams and training requirements set by their boards.

When do Connecticut contractor registrations expire?

Home improvement and new home construction registrations expire every March 31. Major contractor registrations expire every June 30. Renew online through eLicense.

Do I need to register if I only work as a subcontractor?

DCP's guide says a subcontractor working only for a registered home improvement contractor does not need its own HIC registration. If you contract directly with a homeowner, you do. Licensed trades still need their trade license either way.
