  1. Connecticut Department of Consumer Protection - Electrical Contractor License (E-1)

    Electrical contractors in Connecticut are licensed by the Department of Consumer Protection under CGS Chapter 393. E-1 is the unlimited electrical contractor license and E-2 the unlimited journeyperson license. Only individuals may apply - DCP does not accept company applications - and the applicant must pass a trade examination given by DCP's exam vendor before the license is issued.

    Official government source

    $150 non-refundable initial contractor license fee and $150 annual renewal set by CGS Sec. 20-335 (journeyperson $90 initial, $120 renewal); the exam vendor charges a separate fee at exam registrationAll electrical licenses expire annually on September 30, so the first term is prorated; the license issues once the applicant passes the DCP trade exam

  2. New Haven zoning compliance and category-specific licenses (no general business license)

    New Haven issues no blanket general business license renewed annually and displayed at the place of business, and Connecticut has no statewide one. The city's Licenses & Permits index routes 'Business License' to the Permit & License Center, whose licences are strictly category-specific - Amusement, Auction and Auctioneer, Broker, Rooming House, Sales and Street Vendor/Peddler - with applications presented in person. What does apply to a business generally is zoning: the premises need a zoning permit or zoning compliance confirmation and a Certificate of Occupancy from the Office of Building Inspection & Enforcement under CGS Sec. 29-265. Note also that the department issuing building and licence approvals is the Office of Building Inspection & Enforcement, not Economic Development.

    Official government source

    No general business license fee exists; zoning, building and category-specific licence fees are set per category by New Haven's adopted fee schedulesA building permit must be issued or refused within 30 days of application (CGS Sec. 29-263(a)); Permit & License Center applications must be presented in person and are not issued same day

  3. New Haven Electrical Permit (per project)

    An electrical permit must be pulled from the City of New Haven's Office of Building Inspection & Enforcement for each electrical project, with a final inspection required on completion. Connecticut abolished county government in 1960, so no New Haven County permit exists. The permit is pulled by the licensed electrical contractor doing the work - Connecticut licenses the electrical trade at state level through the Department of Consumer Protection - and CGS Sec. 29-263(a) bars the building official from issuing a permit to a contractor required to be registered unless that contractor's name, business address and DCP registration number appear on the application.

    Official government source

    Set by the municipality's adopted permit fee schedule and scaled to the declared value of the work; every Connecticut building permit also carries a state code-education fee assessed per $1,000 of declared construction value (CGS Sec. 29-263(b))The building official must issue or refuse the permit within 30 days of the application (CGS Sec. 29-263(a)); a final inspection is required when the work is complete
