Connecticut trade license reciprocity

Connecticut licenses electricians statewide through the Department of Consumer Protection (DCP); the journeyman-level license is the E-2 Unlimited Electrical Journeyperson, which allows all electrical work defined in CGS 20-330 while employed by a licensed contractor (limited journeyperson classes such as C-6, L-2, L-6, T-2 and PV-2 also exist). A new E-2 applicant qualifies through a Connecticut apprenticeship, through equivalent experience and training, or by holding an equivalent out-of-state license, and in every path must pass the PSI-administered E-2 exam (80 questions, 3.5 hours, 70%, open book on the 2020 or 2023 NEC). DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction, even though CGS 20-333a would allow the Commissioner to waive the exam for licensees of states that reciprocate. The application fee is $90, the exam is $59 per portion, and the initial license fee is $120; licenses expire every September 30 and renew for $120.

Connecticut has no license titled 'master electrician'; the top-tier personal license is the E-1 Unlimited Electrical Contractor, issued by DCP to an individual (DCP licenses individuals, not companies) and permitting all electrical work under CGS 20-330, pulling permits and contracting with the public. A new E-1 applicant needs 720 classroom hours matching DCP's Exhibit A curriculum and 12,000 OJT hours (8,000 as an apprentice plus 4,000 hours, two years, working as a licensed journeyperson), reachable through two years as a Connecticut journeyperson, equivalent experience and training, or an equivalent out-of-state license, and must pass both the PSI E-1 trade exam (100 questions, 4 hours, 70%) and the Business and Law exam (50 questions, 2 hours, 70%). DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction. Fees are a $150 application fee, $59 per exam portion and a $150 initial license fee; licenses expire every September 30 and renew for $150.

Connecticut licenses HVAC work statewide through the Department of Consumer Protection (DCP) as 'heating, piping and cooling' work; the journeyman-level credential is the S-2 Unlimited Heating, Piping and Cooling Journeyperson, which covers all heating, piping and cooling work defined in CGS 20-330 while employed by a licensed contractor. Narrower journeyperson classes exist for technicians whose experience is limited to part of the trade, chiefly the D-2 Limited Warm Air, Air Conditioning and Refrigeration Journeyperson (no oil burner servicing) and the B-2 Limited Gas and Oil Burner Journeyperson, plus D-4 cooling-only, G-2 gas piping and S-10 light heating-cooling classes. A new S-2 applicant qualifies through a Connecticut apprenticeship, through equivalent experience and training (8,000 on-the-job hours and 576 classroom hours), or by holding an equivalent out-of-state license, and in every path must pass the PSI-administered S-2 exam (70 questions, 3 hours, 70%, open book). DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction, even though CGS 20-333a would allow the Commissioner to waive the exam for licensees of states that reciprocate. The application fee is $90, the exam is $59 per portion and the initial license fee is $120; licenses expire every August 31 and renew for $120. EPA Section 608 refrigerant certification is a separate federal requirement for anyone handling refrigerants.

Connecticut has no license titled 'master HVAC'; the top-tier personal credential is the S-1 Unlimited Heating, Piping and Cooling Contractor, issued by DCP to an individual (DCP licenses individuals, not companies) and permitting all heating, piping and cooling work under CGS 20-330, pulling permits and contracting with the public. Limited contractor classes cover narrower scopes, chiefly the D-1 Limited Warm Air, Air Conditioning and Refrigeration Contractor and the B-1 Limited Gas and Oil Burner Contractor. A new S-1 applicant needs 576 classroom hours matching DCP's Exhibit A curriculum and 12,000 OJT hours (8,000 as an apprentice plus two years, 4,000 hours, working as a licensed journeyperson), reachable through two years as a Connecticut journeyperson, equivalent experience and training, or an equivalent out-of-state license, and must pass both the PSI S-1 trade exam (80 questions, 3 hours, 70%) and the Business and Law exam (50 questions, 2 hours, 70%). CGS 20-334a(a)(1) expressly allows journeyman service performed outside Connecticut to count if DCP finds it comparable. DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction. Fees are a $150 application fee, $59 per exam portion and a $150 initial license fee; licenses expire every August 31 and renew for $150.

Connecticut licenses plumbers statewide through the Department of Consumer Protection (DCP) under CGS Chapter 393 (plumbing and piping work). The journeyman-level credential is the P-2 Unlimited Journeyperson Plumber, which covers all plumbing and piping work defined in CGS 20-330 while employed by a contractor licensed for that work. Narrower journeyperson classes exist (J-2 well pumps, J-4 lawn sprinkler, P-6 sewer/storm/water, P-8 gasoline tank piping, PP-2 process piping, SP-2 spa and pool). A new P-2 applicant qualifies through a registered apprenticeship, equivalent experience and training, or an equivalent out-of-state license (576 classroom hours matching Exhibit A and 8,000 on-the-job hours) and, under CGS 20-333 and 20-334a(a)(2), must pass the state licensure examination. CGS 20-333a would allow the Commissioner to waive the exam only if the origin state reciprocates for Connecticut licensees, and DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction. Application fee $90 (non-refundable) and initial/renewal license fee $120; all plumbing and pipefitting licenses expire annually on October 31.

Connecticut has no license titled 'master plumber'; the top-tier personal credential is the P-1 Unlimited Plumbing Contractor, issued by DCP to an individual and permitting all plumbing and piping work under CGS 20-330 (permits and contracting with the public). Limited contractor classes cover narrower scopes (J-1, J-3, P-7, P-9, PP-1, SP-1). A new P-1 applicant needs two years as an unlimited licensed journeyperson or equivalent experience and training; the out-of-state equivalency table is 12,000 OJT hours (8,000 plus two years / 4,000) and 576 classroom hours matching Exhibit A. CGS 20-334a(a)(1)(A) lets out-of-state journeyman service count if DCP finds it comparable, and still requires the contractor examination. CGS 20-333a would allow an exam waiver only if the origin state reciprocates, and DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction. Fees are a $150 application fee and a $150 initial/renewal license fee; licenses expire annually on October 31.

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.

Connecticut issues no general, commercial or unlimited building contractor license. There is no state exam, no classification letter, no monetary limit tier and no qualifying party to become: a contractor may build, remodel or fit out a commercial building in Connecticut without holding any state contractor credential at all. What the state regulates instead is narrower and sits in three places. First, the trades: CGS chapter 393 licenses six occupations through examining boards at the Department of Consumer Protection - electrical work, plumbing and piping work, heating, piping, cooling and sheet metal work, elevator installation, repair and maintenance, fire protection sprinkler systems work, and automotive and flat glass work - so a general contractor meets those requirements by employing or subcontracting to the licensed firm. Second, structural work on large buildings: anyone who constructs, structurally repairs, structurally alters, dismantles or demolishes a structure that exceeds the threshold limits in CGS 29-276b - roughly four stories, 60 feet tall, a 150-foot clear span, 150,000 square feet of gross floor area or an occupancy of 1,000, with separate thresholds for institutional, residential and storage uses - must hold a Major Contractor Registration, and so must a subcontractor whose roofing, masonry or structural frame work affects the structural integrity of such a building. That registration is a screening rather than a qualification: DCP asks for two credit references, one from a supplier or subcontractor and one from a financial institution, and sets no examination, experience or education requirement; it renews every June 30 for $500, and a contractor prequalified with the Department of Administrative Services is registered without a fee. It does not reach smaller commercial buildings, new homes or residential work. Third, public money: bidding on a state or municipal construction contract estimated above $1,000,000 requires DAS prequalification under CGS 4a-100, which is bidder eligibility for public work and not a license to build privately. Connecticut municipalities do not license contractors; building departments enforce the statewide State Building Code and issue permits, and a commercial permit is issued to the project rather than against a contractor license. Connecticut also once had a Home Building Contractors chapter, CGS chapter 400d, and repealed it - the surviving credentials are the two consumer registrations described on the residential page.

Connecticut licenses home inspectors statewide through the Department of Consumer Protection under chapter 400f of the General Statutes, advised by an eight-member Home Inspection Licensing Board that sits inside the department. No one may examine and report on two or more systems of a one-to-four-family residential building for a fee without that license, although the statute leaves licensed architects and professional engineers outside the chapter altogether and lets electricians, plumbers, appraisers, insurance adjusters and other license holders keep working inside their own credentials. Connecticut reaches the license through a real two-stage route. A candidate first earns a Home Inspector Intern permit, which asks for a high school diploma or equivalent, a completed board-approved Home Inspection Intern Training Program of at least forty hours covering general home inspection, Connecticut license law, specialized practice areas and business law, and a named Connecticut-licensed supervisor who has agreed to supervise. The intern then performs at least one hundred inspections, the first ten with the supervisor present on site for the whole inspection and countersigning every document, keeps a signed log of them, and passes the licensing examination. The intern permit is a training credential rather than a second destination, so the full Home Inspector license is what an experienced inspector moving to Connecticut applies for, and section 20-492c lets that inspector skip the intern stage: on a written application and a $100 fee the department issues a license to anyone holding a valid license from another state whose standards it finds substantially equivalent to or exceeding Connecticut's. Either the Connecticut state examination or the National Home Inspector Examination satisfies the examination requirement, and the department's testing contractor is PSI. Connecticut requires no errors and omissions cover, no general liability cover and no bond from home inspectors, and it runs no guaranty fund for them: the department's Home Improvement, New Home Construction, Real Estate and Health Club funds cover other credential holders. Licenses expire on June 30 of odd-numbered years, renewal costs $250, and 20 continuing education hours are due each two-year cycle.
