Construction Liability Insurance

Construction liability insurance covers third-party bodily injury and property damage arising from your work — both while a project is active and, through completed-operations coverage, for years after it's finished. For California contractors, getting the ongoing-versus-completed-operations distinction right is one of the most consequential coverage decisions in the whole program.

Ongoing operations vs. completed operations

General liability splits into two distinct exposure periods: ongoing operations, covering claims that arise while you're actively working a project, and completed operations, covering claims that arise after the work is finished and the client has taken possession.

Construction defect and latent-damage claims routinely surface months or years after a project closes — a policy written without adequate completed-operations coverage leaves that entire tail exposed.

Ongoing operations covers claims during active work

Completed operations covers claims after project handoff

Construction defect claims often surface years later

Both exposure periods need to be addressed, not just one

Subcontractor liability and additional insured status

General contractors typically require subcontractors to carry their own liability coverage and name the GC as an additional insured — a specific endorsement, not something a certificate alone provides.

If you're the sub, confirm your policy can actually issue that endorsement before you commit to the contract's insurance requirements. If you're the GC, verify the endorsement in the issued policy, not just the certificate.

Subs are typically required to carry their own liability coverage

Additional insured status requires a specific endorsement

A certificate of insurance alone doesn't satisfy the requirement

Verify the endorsement in the actual policy

What drives construction liability pricing

Classification accuracy — matching your policy to your actual scope of work — is the single biggest driver of fair pricing. Misclassified operations lead to either overpaying or, worse, a coverage gap at claim time.

Complete loss history, project types, and subcontracted-versus-self-performed work all factor into how an underwriter prices the risk.

Subcontracted vs. self-performed work affects rating

Limits that match real contract requirements

Most California GC and lender contracts specify minimum liability limits — often $1M per occurrence / $2M aggregate as a baseline, sometimes higher for larger commercial projects.

Read the actual contract's insurance requirements before assuming your existing limits satisfy it — an umbrella policy is often the most cost-effective way to reach a higher required limit.

A realistic scenario: a defect discovered after the policy lapsed

A contractor completes a project, lets the general liability policy lapse a year later when switching carriers, and then a construction defect from the completed project surfaces two years after that — assuming the current policy will respond since that's the one active today.

Illustrative only — this describes a typical pattern, not an actual case or guaranteed outcome. Completed operations claims are generally tied to the policy that was active when the work was performed, not the policy active when the defect is discovered — which is exactly why continuous coverage without gaps matters more for this exposure than almost any other.

Not the policy active when the defect is later discovered

A coverage lapse between the work and the discovery is a real gap

Continuous coverage matters more here than for most other exposures

Frequently asked questions

8 questions — start typing to filter

What's the difference between ongoing and completed operations coverage?

Ongoing operations covers claims while you're actively working; completed operations covers claims that arise after the project is finished and handed off — construction defect claims often fall into this second category, sometimes years later.

Does a certificate of insurance satisfy an additional insured requirement?

No — a certificate is a summary document. Additional insured status requires a specific endorsement in the actual policy, which should be verified directly, not assumed from the certificate.

What liability limits do most California construction contracts require?

$1M per occurrence / $2M aggregate is a common baseline, though larger commercial and public projects often require more — always read the actual contract.

How is construction liability priced?

Classification accuracy against your real scope of work, complete loss history, and project type all factor into pricing — misclassification is the most common cause of either overpaying or having a coverage gap.

Does Gleason Insurance Brokers place construction liability coverage throughout California?

Yes — we place general liability coverage, including completed operations, for contractors throughout California and our other licensed states.

Does construction liability insurance cover defective work itself?

Generally no — general liability covers third-party bodily injury and property damage, not the cost to redo your own defective work. That's a distinct, often excluded exposure worth discussing directly with your broker.

How often should construction liability limits be reviewed?

At minimum annually, and any time your typical project size or contract requirements change — limits that fit a smaller job may fall short on a larger one.

Is commercial business auto insurance required in California for a single company truck?

Yes, if the vehicle is titled to or regularly used for the business — commercial business auto insurance applies even to a single vehicle, not just multi-truck fleets.
