What insurance does a general contractor need?

Three different authorities decide what a general contractor “needs,” and they don’t coordinate. Your state license board sets a floor, your state workers’ comp statute sets a mandate, and the insurance exhibit in every contract you sign sets the real number. Contractors rarely get in trouble with the first two; they get in trouble when a project’s requirement schedule demands limits and endorsements their program doesn’t have — which is exactly the situation that sends people to insurance forums asking someone to translate a subcontractor agreement.

The stack and who actually demands it

What licensing actually requires

This varies more than any carrier page admits. Washington won’t register a construction contractor without proof of $200,000 in public liability and $50,000 property damage coverage (or a $250,000 combined single limit), plus a $30,000 bond for general contractors and $15,000 for specialty trades. Other states require only the bond, or nothing beyond workers’ comp. Check your board’s registration page, not a national average.

Workers’ comp is where construction is treated differently on purpose. Florida requires coverage for construction businesses at one employee — including non-exempt owners — while its non-construction threshold is four. Most states draw a similarly hard line for the trades. If you have a crew, assume you’re over the line until your state’s workers’ comp authority says otherwise.

What contracts demand

The contract, not the law, sets a working GC’s real insurance program. Standard asks in owner and developer agreements:

• Specific GL limits — $1M per occurrence / $2M aggregate is the floor; larger projects push higher and add an umbrella requirement.
• Additional insured status for the owner, including completed operations — the claims that arrive years after you’ve left the site.
• Primary and non-contributory wording, so your policy pays before theirs.
• Waiver of subrogation and a certificate of insurance before mobilization.

Read the requirement schedule before you bid, not after. If it demands a $5M umbrella you don’t carry, that’s a cost of the job — see whether a $5M umbrella requirement is normal.

Your subs are your exposure

A GC’s insurance program is only as good as its subcontractors’ paperwork. Under Florida’s workers’ comp law, if a sub’s worker is injured and the sub never secured coverage, the contractor becomes responsible for the benefits — the statute deems everyone on the contract work employed in one and the same business. Many states have similar contractor-liability rules. Collect a certificate from every sub before their first day, and verify it; whether contractor insurance covers subcontractors is its own question with an unpleasant answer.

A decision path

1. Look up your state license board’s insurance and bond requirements — that’s your registration floor.
2. Count employees against your state’s construction workers’ comp threshold; in several states the answer is one.
3. Set GL limits from the contracts you want to win, not the legal minimum.
4. Any owned or employee-driven vehicles → commercial auto.
5. Build the sub file: certificates, additional insured endorsements, and workers’ comp verification for every sub, every project.

Questions contractors actually ask

Do general contractors need insurance? There’s rarely a single statute saying so, but between license boards, workers’ comp law, and contract requirements, an uninsured GC can’t legally or practically operate in most states.

How much insurance does a general contractor need? The limits question is answered by your contracts: $1M/$2M GL is the standard floor, and commercial work increasingly layers an umbrella above it.

Do contractors need E&O insurance? Most contractors asking this mean general liability. E&O for contractors covers design and consulting errors — relevant if you do design-build, otherwise secondary.

Do general contractors need workers’ comp? Once you cross your state’s construction threshold, yes — and in states like Florida that threshold is one employee, counting non-exempt owners.
