Illinois to Connecticut: residential contractor license reciprocity
Illinois does not issue a statewide residential contractor license, so there is nothing to transfer. Here is Connecticut's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Everyone registers the same way; an out-of-state contractor license transfers nothing
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A residential contractor licensed or registered in another state registers in Connecticut exactly as a first-time applicant does, and the out-of-state credential neither helps nor hinders. The Department of Consumer Protection does not review, verify or credit another state's contractor license for a home improvement or new home construction registration, and it has nothing to waive: chapter 400 and chapter 399a contain no examination, no experience requirement, no education requirement and no interstate or reciprocity provision at all. Connecticut is also not one of the agencies that accept the NASCLA Accredited Examination for Commercial General Building Contractors, for the same reason - it holds no contractor examination for that examination to stand in for. The steps are identical for an applicant from Rhode Island, from Florida or from the next town. If you will contract through an LLC, corporation or other legal entity, register that entity with the Connecticut Secretary of the State first; out-of-state entities are expressly included. Buy general liability insurance of at least $20,000 and have the insurer's business name and policy number to hand. Then apply online through elicense.ct.gov and pay $220 for a home improvement contractor registration, or $360 for a new home construction contractor registration, plus $100 if you want home improvement work added to the new home registration. Both registrations expire every March 31 and renew online for the same amount.
DCP does not publish a processing time for either registration. Applications and renewals are online only; the department no longer accepts paper renewal notices or checks by mail or drop box. Renewal notices go out about 30 days before the March 31 expiry, and failing to receive one does not excuse a late renewal. Registration is not a permit: no contractor may start work until the municipal building official has issued the applicable building permit, and for new home construction the building official may not issue the permit until the contractor produces the registration certificate and number. A Connecticut home improvement contract is unenforceable against the homeowner unless it is in writing, signed, dated, carries the contractor's registration number, gives start and completion dates and includes the cancellation notice required by CGS 20-429; new home construction contracts have a matching list in CGS 20-417k. The Home Improvement Guaranty Fund pays a homeowner at most $25,000 on a single claim and the New Home Construction Guaranty Fund at most $30,000, and DCP can revoke a registration until the contractor repays the fund.

What you must already have
- No trade examination, business-and-law examination, apprenticeship, classroom hours, years of experience, financial statement or qualifying party is required. Nothing in the application asks what you have built before, so documented years of homebuilding in another state neither shorten nor replace any step.Confirmed against the full text of CGS chapter 400 and chapter 399a and against both DCP application pages. The narrow exceptions sit inside the home improvement registration rather than above it: a contractor who performs radon mitigation must be certified by the National Radon Safety Board or the National Environmental Health Association, and one who removes or replaces a residential underground heating oil storage tank must have completed a DEEP-approved hazardous material training program and carry $1,000,000 of liability coverage (CGS 20-420(a)).
- Decide before applying whether the registration is person-held or entity-held. Registering as an individual sole proprietor does not cover an LLC or corporation you contract through. A business entity registers in its own name, lists its individual owners and designates the registered individual or individuals who will direct or supervise its home improvement work.CGS 20-420a(a), (b) and (d). The designated individual is a supervisory contact, not a qualifying party in the sense other states use: no competency test attaches to the designation.
- Every applicant, and every individual owner of an applicant business entity, must disclose any finding of guilt or conviction for an act that is a felony under Connecticut or federal law, or that would be a felony in Connecticut if committed elsewhere.CGS 20-421(a)(2) and 20-420a(b)(3). DCP may refuse or revoke a registration based on a felony conviction of an individual registrant or an individual owner, subject to CGS 46a-80 (CGS 20-426(a)(6)). Attach DCP's Criminal Conviction Application Worksheet (CHRO) where it applies.
- A business entity must be in good standing with the Connecticut Secretary of the State when it applies and when it renews, and must notify DCP of any change in that standing within thirty days.CGS 20-420a(e). Both DCP application pages state that legal entities, in-state and out-of-state alike, must register the business with the Secretary of the State before applying.
What you'll do to get licensed in Connecticut
- 1Application fee. Pay the application fee ($120). Home improvement contractor registration fee (CGS 20-421(b)). DCP collects it together with the $100 Home Improvement Guaranty Fund fee, so the department's page prints a single non-refundable application fee of $220.00. The registration expires on March 31 and renews online for the same $220. No application fee is charged for a year in which you have paid the new home construction registration fee or hold a valid NHC registration, and the fee is waived for a registration used solely to direct, supervise or perform home improvements for a business entity you own..
- 2Other. Home Improvement Guaranty Fund fee of $100 a year, payable with the application and with every renewal (CGS 20-432(b)). The fund reimburses a homeowner who wins an arbitration decision, judgment or restitution order against a registered contractor and cannot collect on it, up to $25,000 for a single claim. It is a consumer indemnity pool rather than insurance for the contractor: if DCP pays a homeowner out of the fund it may revoke the registration, and the contractor cannot be registered again until the fund is repaid with interest or a payment agreement is in place. ($100).
- 3Insurance. Carry the required insurance ($20,000). General liability insurance of not less than $20,000, required since Public Act 21-197 took effect on July 1, 2022. The application and the online renewal both ask for the insurance provider's business name and the policy number rather than a certificate. This is a floor set for registration, not a commercial limit: most residential work in Connecticut will call for far more coverage by contract or by lender requirement..
- 4Business license. Obtain a business license. Registration of the contracting entity with the Connecticut Secretary of the State, required of legal entities formed in Connecticut and of those formed in another state, before the DCP application is filed. A sole proprietor registering as an individual does not file with the Secretary of the State, but then the registration covers only that individual and not any company. A business entity must stay in good standing throughout, and must tell DCP within thirty days if that changes..
- 5Other. Online application through elicense.ct.gov. DCP accepts applications and renewals online only. Choose the individual (sole proprietorship) or legal entity form first, because switching later takes a separate ownership-change or sole-proprietor-to-legal-entity form. An entity application also lists the individual owners and designates the registered individual or individuals who will direct or supervise its home improvement work..
- 6Application fee. Pay the application fee ($120) (if applicable). New Home Construction Contractor registration fee (CGS 20-417b(b)), needed only if you will contract to build or sell a new single-family house, two-family dwelling or condominium unit before occupancy, including speculative and modular homes. DCP collects it with the New Home Construction Guaranty Fund fee for a single non-refundable $360.00 total, renewable each March 31 for the same amount. If you build new homes and also remodel, apply for the NHC registration first and add the home improvement designation to it; a separate home improvement application fee is not charged in a year when the NHC registration is valid..
- 7Other. New Home Construction Guaranty Fund fee of $240 a year, payable with the new home construction registration and each renewal (CGS 20-417i(b)). It reimburses a buyer who obtains a judgment, arbitration decision or restitution order against a registered new home construction contractor and cannot collect, up to $30,000. Adding home improvement work to an active NHC registration costs a further $100, which is the Home Improvement Guaranty Fund fee. ($240) (if applicable).
- 8Other. Separate credentials where the work calls for them. A home improvement or new home registration does not authorize electrical, plumbing and piping, heating, piping and cooling, elevator, fire protection sprinkler or glass work; each of those is examined and licensed under CGS chapter 393, and a tradesperson licensed there needs no home improvement registration for that work. Radon mitigation requires certification by the National Radon Safety Board or the National Environmental Health Association. Removing or replacing a residential underground heating oil storage tank requires a hazardous material training program approved by the Department of Energy and Environmental Protection plus $1,000,000 in liability coverage. Structural work on a threshold building calls for the separate Major Contractor Registration described on the general page. (if applicable).
Published fees on this path total $120, excluding exam-vendor fees, bonds, and insurance.

How Connecticut licenses residential contractors
Connecticut residential contractor · “Home Improvement Contractor (HIC) registration; New Home Construction Contractor (NHC) registration”
Statewide license
Issued by Connecticut Department of Consumer Protection, License Services Division
Connecticut does not license residential contractors for competency. The Department of Consumer Protection registers them under two consumer-protection statutes, and that registration is the only credential a remodeler or homebuilder needs. A Home Improvement Contractor (HIC) registration under the Home Improvement Act (CGS chapter 400) covers permanent work on residential property where the contract price exceeds $200 - driveways, pools, porches, garages, roofs, siding, insulation, flooring, patios, landscaping, painting, fences, doors, windows, waterproofing and alarm systems not requiring electrical work. A New Home Construction Contractor (NHC) registration under CGS chapter 399a covers contracting to build or sell a new single-family house, two-family dwelling or condominium unit before occupancy, including speculative housing and modular homes. Neither one involves an examination, an apprenticeship, an experience requirement, an education requirement, a financial statement, a surety bond or a named qualifying party: the statutes and DCP's application pages ask only for identity, a felony-conviction disclosure, general liability insurance of at least $20,000 and the fee. Connecticut says so itself. A home improvement contractor may not 'represent in any manner that such person's registration constitutes an endorsement of the quality of such person's workmanship or of such person's competency by the commissioner' (CGS 20-427(b)(6)), and a new home construction contractor must hand every buyer a written notice disclosing the same thing before signing (CGS 20-417d). The registration can be person-held or entity-held and you choose before you apply: registering as an individual does not cover an LLC you contract through, and a registered business entity must separately designate the registered individual or individuals who will direct or supervise its home improvement work. A contractor who does both kinds of work registers as an NHC first and adds the home improvement designation to that registration for $100 rather than buying a second registration. Licensed tradespeople are carved out - an electrician, plumber, HVAC contractor, elevator mechanic or sprinkler fitter licensed under CGS chapter 393 needs no home improvement or new home registration for the work that license covers.
Why Illinois has nothing to transfer
Illinois residential contractor · “No statewide license; local titles include Chicago General Contractor Class D or E and Chicago Home Repair”
Licensed by cities and counties
Illinois issues no statewide residential contractor, home builder or remodeler license, and no state agency examines or qualifies people who build or remodel houses. What the State does license is narrower and worth knowing: the Department of Financial and Professional Regulation licenses roofing contractors under the Illinois Roofing Industry Licensing Act, where a limited license covers residential properties of eight units or less and an unlimited license covers residential, commercial and industrial roofs, and a municipality or county may not issue a building permit to a roofing contractor without proof of that state license. IDFPR also licenses architects, professional and structural engineers, land surveyors and alarm contractors, and the Department of Public Health licenses plumbers, plumbing contractors and irrigation contractors, but nowhere on IDFPR's list of regulated professions is there a general, residential or building contractor. Everything else is local: Illinois municipalities are home rule units and license or register residential contractors one jurisdiction at a time, with the City of Chicago's General Contractor license by far the most consequential. A builder moving to Illinois therefore has no state license to transfer and no reciprocity to apply for; the practical work is registering in each city or county where they will pull permits, carrying the insurance each one demands, and obtaining the state roofing license if the company will do roofing. Statewide consumer law still applies: the Home Repair and Remodeling Act requires a written contract for any home repair or remodeling job over $1,000 and the "Home Repair: Know Your Consumer Rights" pamphlet on every job.
How local licensing works in Illinois
How it works in Illinois. There is no state license, no state application and no state exam for residential contractors. Each municipality decides who may pull a residential building permit, so a contractor must be licensed or registered separately in every jurisdiction where they build, and a credential from one Illinois city is not valid in the next. Almost all of these local programs are about identity, insurance, bonding and fees rather than trade competence, and none of them reviews or credits a residential contractor license held in another state. Roofing is the exception in the other direction: the State license is mandatory everywhere in Illinois, and cities from Rockford to Joliet to Cook County check it at the permit counter.
Chicago. This is the license that matters. 'A City of Chicago general contractor license is required to perform most types of building construction, alteration, repair, and demolition work within the City of Chicago', and it is needed to bid on, undertake, hire or supervise, or control the means and methods of work requiring a building, sign or demolition permit. Licenses are issued to businesses, including sole proprietorships, in five classes set by project value - the fair market value of materials and labor supplied by all contractors and subcontractors across all concurrent and consecutive work at the same site. The two classes a homebuilder or remodeler usually needs are Class D, capped at $4 million with ordinary demolition and $2 million per occurrence of insurance, at a $900.00 license and renewal fee, and Class E, capped at $500,000 with no demolition and $1 million per occurrence, at $300.00. There is no exam, no experience review and no qualifying party. The application asks for a statement of financial solvency in the format supplied, proof of authority to do business in Illinois (not required for sole proprietors), an Assumed Name Certificate from the County Clerk if a trade name is used, proof of insurance for the class from an insurer authorized in Illinois and rated B+ or better by A.M. Best, and government photo identification for the controlling persons. Continental Testing Services processes the application and renewal by mail for the Department of Buildings; the license runs one year and 'is automatically inactivated if the associated insurance policy expires.' Reinstatement costs $100.00 per year or part year expired.
Chicago, work that does not need a permit. A business that fixes, replaces, alters, modernizes, improves or adds to residential property but does not need a building permit takes a Home Repair license from Business Affairs and Consumer Protection instead: $1,000.00 for a two-year term, with a certificate of insurance of at least $300,000 per occurrence, and the rule that 'Home Repair licensees may not pull building permits.' A general contractor license replaces it - 'a home repair license is not required for a business that holds a General Contractor license', though a general contractor doing residential work must still follow the home repair consumer protection rules, which include a written estimate before work, a written invoice on completion, prior approval before exceeding the estimate, and the license number on contracts, advertisements and vehicles. Acquiring vacant land to build a new home, or renovating more than half of an existing building's floor area, requires a separate Residential Real Estate Developer license.
Cook County (unincorporated areas). 'All contractors performing work in unincorporated Cook County are required to register with the Cook County Department of Building and Zoning.' Registration costs $150 per trade initially and $75 per trade annually, due by December 31, and needs a $1,000,000 general liability certificate naming Cook County Building and Zoning at 69 W. Washington, Suite 2830, Chicago as certificate holder, filed by the owner or a corporate officer with the Articles of Incorporation or the current Annual Domestic Report. Roofing registrants must submit the State of Illinois roofing license and demolition registrants an approved bond. There is no exam. Homeowners who live on the property get 'General' contractor registration free of charge. Use the county's CookViewer tool first to check whether a site is actually unincorporated. Contact [email protected] or 312-603-0512.
Aurora. The Division of Building and Permits registers a General contractor for a $200 fee. The packet is the Contractor Licensing Application, a certificate of insurance naming the City of Aurora as primary and non-contributory additional insured with $1,000,000 general aggregate and $500,000 per occurrence, workers' compensation in compliance with Illinois statute, and proof the business is registered with the Secretary of State or a county DBA certificate. There is no test for the General category - Aurora's municipal testing applies only to electrical and mechanical contractors, who may use ICC certifications or a license from an accepted testing municipality instead. Roofing registration is also $200 and requires the state license, and workers' compensation cannot be replaced by an employee affidavit for roofers. Outstanding or expired permits will block a renewal. Submit to [email protected]; 77 S Broadway, (630) 256-3130.
Evanston. 'All contractors performing work within City limits are required to register with the City, including but not limited to General Contractors, Electrical, Carpentry, Concrete, Excavation, Masonry, Landscaping, Fence, Roofing and Sign contractors.' General Contractor registration is $150 and trade registration $125, both renewable annually through the Citizen Portal. Insurance must be general liability of at least $300,000 per occurrence, bodily injury of at least $100,000 per occurrence, property damage of at least $100,000 per occurrence and workers' compensation at statutory minimums, with Evanston as certificate holder; sole proprietors and partnerships with no employees may file an affidavit in place of workers' compensation, and right-of-way work needs $1,000,000 per occurrence naming the city as additional insured. State-regulated contractors submit a copy of the state license. An owner-occupant of a single-unit residence may act as their own general contractor.
Joliet. 'All contractors performing work within the City of Joliet must have current registration on file prior to permit issuance. There are no forms or fees for registration, unless you are a Sign Erector or for HVAC Testing.' Registration is a certificate of insurance naming the City of Joliet as certificate holder, with minimum limits of $250,000 bodily injury per person, $500,000 bodily injury per occurrence and $250,000 property damage per occurrence, emailed to [email protected]. Roofing needs the Illinois State Roofer's License, plumbing the Illinois Plumbing Contractor Registration, irrigation the state irrigation license, siding a Vinyl Siding Installers certificate, and electrical and HVAC a license from one of the municipalities Joliet accepts. Electrical, plumbing and HVAC contractors also file a project-specific Letter of Intent, and all subcontractors must be listed on the permit application.
Rockford. 'General contractors are not required to be licensed.' Rockford requires a building permit for any structure over 120 square feet that is constructed, altered, enlarged, repaired or moved, and for all roofing work, and notes that 'roofing contractors are required to obtain a license from the State of Illinois Department of Professional Regulation.' Tent erectors and outdoor sign contractors need annual city licenses.
Springfield. The Building and Zoning Department's published list of applications contains electrical and mechanical contractor registrations and licenses and nothing else for contractors - there is no general contractor or home improvement registration. The city's building permit application collects the general contractor's name and address but asks for a license number only on the roofing line. Building and Zoning is at 300 South 7th Street, Room 304, (217) 789-2171.
Peoria. Peoria's Contractor Business Licenses cover only four activities - parking lot paving, sidewalk and driveway work, placing a dumpster or storage unit in the right-of-way, and sewer connections - at $25.00 or $60.00 a year with license and permit bonds of $5,000 or $10,000. Its trade licenses cover electrical and HVAC contractors at $150.00 each, issued to individuals rather than businesses and requiring an open-book ICC exam unless the applicant holds a Normal or Pekin license, plus boiler tender and stationary engineer licenses. There is no general building contractor or residential builder license in Peoria.
Everywhere else. Other Illinois municipalities set their own rules and most of them register rather than license residential builders. Ask the building or development services department of each city, village or county before contracting there, and confirm the current fee and insurance limits before buying coverage, because these are set locally and change independently.
