Connecticut Contractor Insurance

Does Connecticut Require Contractors to Carry Insurance?

Workers' compensation, once you have employees. General liability, not as a condition of home improvement registration.

One correction worth making, because it circulates widely. Several sites claim Connecticut General Statutes section 20-429 requires home improvement contractors to carry $1 million in general liability. It does not. That section governs what a home improvement contract must contain in order to be enforceable, and it says nothing about insurance limits.

The Guaranty Fund Protects Your Customer, Not You

Every registered home improvement contractor contributes to the Home Improvement Guaranty Fund. It reimburses homeowners harmed by a registered contractor, up to $25,000 per claim, covering actual damages and court costs rather than punitive damages.

A homeowner must first obtain a judgment, arbitration award, or restitution order, and you must have been registered when the contract was signed or at some point in the two years before it. The fund pays your customer. It is a consumer remedy, not coverage for your business, and it sits alongside a possible DCP action against your registration.

Connecticut Voids Hold Harmless Clauses, but Additional Insured Coverage Survives

Two definitions first. The promisor is the party promising to cover someone else's liability, usually you. The promisee is the party being covered, usually the general contractor or owner.

Section 52-572k makes a hold harmless or indemnity clause void as against public policy where it covers the promisee against liability for injury or property damage caused by the promisee's own negligence, or that of their agents or employees. It applies to construction, alteration, repair, and maintenance work, including moving, demolition, and excavation.

The statute carries an express carve-out: it does not affect the validity of an insurance contract or other agreement issued by a licensed insurer. Connecticut courts have read that carve-out to mean enforcing an additional insured clause does not violate the section, and have held that a waiver of subrogation is not a hold harmless or indemnity agreement at all.

That combination is unusual, and it cuts against the assumption most subcontractors carry into a negotiation. Striking the indemnity paragraph does not necessarily remove the risk transfer, because the insurance requirements sitting next to it can still do the work. Read both, not just the one labeled indemnification. Whether a specific clause holds up is a question for a Connecticut construction attorney, not an insurance agent.

What Connecticut Contractor Insurance Costs

Contractor general liability is generally rated per $1,000 of gross receipts or payroll, with the class code setting the rate. That mechanism sits behind every quote you receive.

As an illustration, a painting contractor rated at $13 per $1,000 of receipts, running $400,000 in annual receipts, sees a base premium near $5,200 before credits, debits, minimum premiums, and endorsement charges. Change the class code and the rate can double or halve. This shows the arithmetic and is not a quote.

The ranges below reflect what we commonly place for Connecticut contractors with modest receipts and clean loss history.

Connecticut's housing stock shapes these numbers. Much of the state's residential work happens in homes built before 1978, which brings lead-safe renovation practices into scope, and older systems mean more of your work sits next to somebody else's failing components. Defect and callback exposure follows, and standard forms handle less of it than owners expect, as our overview of what general liability does not do for construction defects explains.

Then there is the audit. Most general liability policies are audited after the term, and receipts above projection generate a bill. Subcontracted cost is the trap: with no certificate for a sub you paid, auditors commonly rate that spend at your own class code. Collect certificates before the first payment, and see verifying subcontractor insurance and how a general liability audit works.
