New Law (Public Act 21-197) Effective July 1, 2022:
- All applicants must obtain general liability insurance of no less than $20,000 to be eligible for a home improvement contractor registration. Applicants will be required to provide the name of their insurance provider and policy number in their application.
- All applications must be submitted online.
- You must determine whether you want to register as an individual (sole proprietorship) or a legal entity (LLC, corporation) prior to applying.
- If you contract with consumers as an LLC, then you should register as an LLC. Holding a home improvement contractor registration as an individual does not cover the LLC.
- Legal entities (both in-state and out-of-state) must register their business with the CT Secretary of State’s Office prior to applying.
- If you will be building new homes, you should apply for a New Home Construction Contractor registration first. You can designate home improvement work as part of that registration process. (see New Home Construction Contractor)
