About each permit
Home Improvement Contractor Registration
The trigger is unusually low: any permanent change to residential property under a contract of $200 or more needs this registration, which puts a great deal of ordinary remodelling work inside it. The consumer protection department's own exemption list is worth knowing precisely — homeowners working on their own property, subcontracted work, work already covered by a trade license, commercial property, routine property maintenance like mowing or snow ploughing, and tree work are all excluded, and building a new home falls instead under the separate new home construction registration below.
New Home Construction Contractor Registration
Building a new home is licensed separately from remodelling an existing one, at $360 rather than the home improvement contractor's $220, with $120 of that earmarked for the state's guaranty fund rather than being pure registration cost. A contractor doing both new construction and home improvement work pays a further $100 to add the second registration rather than paying for each in full. The expiry date moved from 30 September to 31 March by a 2022 statutory change, so anything published before July 2022 has the wrong renewal month.
Heating, Cooling and Sheet Metal License
Connecticut's third individual trade license on the same $150-and-$150 pattern, with its own expiry date of 31 August — a contractor holding electrical, plumbing and HVAC licenses together is renewing on three separate dates across the year rather than one shared date.
Plumbing and Pipefitting License
Structurally identical to the electrical license — $150 to apply and $150 a year to renew, issued to the individual rather than the firm — but on its own expiry date, 31 October rather than 30 September, so a business holding both licenses renews them separately across the calendar.
Electrical Contractor License
The license belongs to the person, not the firm — the consumer protection department states plainly that only individuals may apply and a company application is not accepted. A contracting business therefore operates under a licensed individual acting as its qualifying contractor rather than the business itself being licensed, which matters when a company changes who does its electrical work. Plumbing and HVAC licensing follow the identical $150-to-apply, $150-a-year structure, differing only in their expiry month.
