Before you sign with a roofer, remodeler, or handyman in Connecticut, you can check three things in about ten minutes. Is the contractor registered with the state? Do they hold the trade license the job needs? Will the work be permitted? This guide covers all three, using the state's own rules.
NeedNow connects you with independent local pros. We don't verify registrations unless we say so on a listing. Please look them up yourself using the steps below.
1. Home Improvement Contractor (HIC) registration
The Department of Consumer Protection (DCP) says an individual or business must register with DCP if they contract with a consumer to perform work on residential property. DCP's contractor manual adds that it is illegal to perform or offer home improvement work in Connecticut without a valid registration.
What counts as home improvement? DCP's list includes "any permanent change to residential property," such as driveways, pools, porches, garages, roofs, siding, insulation, flooring, patios, landscaping, painting, fences, doors and windows, waterproofing, and alarm systems that don't require electrical work.
What doesn't need an HIC registration? DCP lists these exclusions:
- Work homeowners do on their own property
- Subcontracted work
- Work covered by the scope of a trade license
- Commercial work
- Contracts under $200
- Property maintenance such as snowplowing, mowing, pruning, or cleaning services
- Tree and shrub cutting and grinding
- Building new homes, which needs a separate New Home Construction Contractor registration
So your house cleaner or lawn service doesn't need an HIC registration for that work. Your roofer, painter, fence installer, or deck builder generally does.
What registration requires. DCP says applicants must carry general liability insurance of at least $20,000. Registrations expire every year on March 31. Registered contractors must show their registration number in all advertising, including business cards, ads, and vehicles.
How to look up a registration
- Ask for the HIC number. It should also be on the contract.
- Search it on the state's eLicense site at elicense.ct.gov. DCP tells consumers to verify licenses and registrations there before hiring.
- Check that the name on the registration matches the business you're signing with. DCP notes that a registration held by an individual doesn't cover that person's LLC.
- Ask for proof of insurance. DCP says a contractor who won't give you their insurance provider and policy number is a red flag. You can also call the insurer to confirm the policy is active.
2. Trade licenses: electrical, plumbing, HVAC, and more
A registration isn't a license. DCP says people doing electrical, HVAC, plumbing, heating, and similar work must have the right Connecticut license. It publishes the scope of work for each license level for electrical, plumbing, heating and cooling, sheet metal, solar, irrigation, pool and spa, and other trades.
You can check trade licenses on eLicense too. If the job mixes trades, such as a bathroom remodel with new wiring and plumbing, expect more than one credential: the general contractor's HIC registration, plus licensed electricians and plumbers for their parts of the work.
3. What a Connecticut home improvement contract must include
DCP's contractor manual says the contract isn't valid or enforceable against the homeowner unless it has all of the following and is signed with a registered contractor:
- The contractor's name, address, and HIC registration number
- The entire agreement, in plain language
- The transaction date (the day you sign), the start date, and the completion date
- Signatures and dates from both the contractor and the homeowner
- A notice of your right to cancel, on a form you can detach
Three-day right to cancel. You can cancel until midnight of the third business day after signing, and DCP notes that Saturday counts as a business day. DCP says homeowners aren't responsible for work done during that window. The only exception is a real emergency that the homeowner starts and describes in their own writing.
Changes must be in writing. DCP's manual says a written estimate isn't a contract. Any change or addition must also be in writing.
Deposits and payment
In a May 2025 release, DCP said legitimate contractors won't ask for more than one-third of the project cost up front. It recommends paying in thirds: a deposit, a payment halfway through, and the rest at completion. DCP says to pay deposits with something traceable, such as a credit card. If a contractor doesn't take cards, pay by check made out to the name on the registration. Never pay in cash or through peer-to-peer apps.
DCP's memory aid for contracts is CATER: Credential, Abstract (the scope), Timeline, Expense, and Right to cancel.
4. Building permits
DCP says many home improvement projects need a building permit from the town where the work is done. Either the homeowner or the contractor can apply, and the permit must be in hand before work begins. DCP also says having the right permit is ultimately the homeowner's responsibility. If your contractor is pulling it, confirm with the building official that it has been issued.
Connecticut uses a single State Building Code, and each town enforces it. Towns publish their own permit rules:
- Branford requires permits for building, altering, repairing, or demolishing a structure, and for replacing electrical, gas, mechanical, or plumbing systems regulated by the code. It also publishes a list of exempt work, such as painting, tiling, and other finish work with no structural changes, and some small sheds and fences. When a contractor applies, Branford's checklist asks for proof of their HIC registration.
- Guilford takes permit applications through its online portal.
- For other towns, the state keeps a list of local building officials.
5. If something goes wrong
- Talk to the contractor first, in writing, and keep copies.
- File a complaint with DCP. DCP asks consumers to fill out its complaint form and email it, with contracts, receipts, and permits, to dcp.complaints@ct.gov.
- The Home Improvement Guaranty Fund can reimburse homeowners up to $25,000 when a contractor who was registered doesn't pay a court judgment or restitution order. You need that judgment first. You must apply within two years of the judgment, and the contractor must have been registered when you signed (or within two years before, or at the time of the judgment). If you hire someone who isn't registered, you lose this protection.
