Which CT classifications count as general contractors

• MCO — Major Contractor
• NHC — New Home Construction Contractor
• HIC — Home Improvement Contractor

A record's classifications array carries these codes, so you can tell a licence that covers the work from one that merely exists.

Run it

curl "https://contractor-license-verification2.p.rapidapi.com/v1/licenses/CT/MCO.0900004" \
  -H "X-RapidAPI-Key: YOUR_KEY" \
  -H "X-RapidAPI-Host: contractor-license-verification2.p.rapidapi.com"

MCO.0900004 is a real CT licence (DELRAY CONTRACTING INC) in this trade, so that call works as written.

Before you rely on it

Connecticut has no single “general contractor” licence, and which of the three a contractor needs depends on the work. Home Improvement Contractor (HIC) is the registration for work on an existing home, and it is the one most homeowners are actually asking about — 134,746 of them. New Home Construction (NHC) covers building a house from scratch. Major Contractor (MCO) is for public works above a dollar threshold. A contractor holding only HIC is not registered to build you a new house.

What Department of Consumer Protection does not publish

• Surety bond
• Workers' compensation
• General liability insurance
• Disciplinary actions
• The qualifying individual behind a licensed company

Full coverage detail, including the caveats that apply to every Connecticut lookup, is on the Connecticut page.
