Commercial Umbrella Insurance

Tell us about your operations and your underlying policies. We review your total exposure with you, explain how the umbrella sits above your primary coverage, and help you set a limit that fits your risk and contracts. We revisit it at renewal as your business grows, and we advocate for you if a large claim hits.

What is the difference between a commercial umbrella and an excess liability policy?

An excess liability policy adds limits above an underlying policy and is no broader than the policy beneath it. A commercial umbrella does more than one job. It adds limits over the scheduled policies. It can continue after an underlying aggregate is exhausted. It can also reach a narrow set of claims the underlying policies do not cover, subject to a retention you accept. The two labels are not interchangeable, and the form decides which one you hold rather than the word on the declarations page. Some insurers now write both in a single contract, with one insuring agreement that follows the underlying terms and a second that reaches further. Read the schedule and the insuring agreements together.

Does an umbrella add limits to my property or catastrophe coverage?

No. An umbrella is third-party liability coverage, and it responds when someone else claims your business injured them or damaged their property. It does not add limits to your building, contents, business income, crime or cyber coverage. It does not respond to fire, theft, flood or earthquake. The word catastrophe, where it appears alongside this product, refers to the severity of a liability claim and not to a natural disaster. If the concern is a wildfire or an earthquake damaging your own premises, that is a property placement, and in California earthquake and flood are arranged separately.

What is a schedule of underlying insurance, and why does a missing policy matter?

The schedule names the policies the umbrella sits above, and the limit each one has to carry. A policy that is not on the schedule is not underlying insurance, and the umbrella does not reach a claim against it. California public agencies write this into their contracts. The Caltrans Revised Standard Specifications require that automobile liability be scheduled on the excess policy in order to count toward the required automobile limits. That is a contracting agency stating plainly that an unscheduled policy does not help you. Check the schedule whenever you add a vehicle, a location or a new entity.

What happens when an underlying limit is used up during the policy term?

It depends on why it was used up, and the two cases do not have the same answer. Where the aggregate is reduced or exhausted by paying claims the underlying policy covers, the standard maintenance of underlying insurance condition treats that as the expected case. The umbrella can then attach at the reduced amount. Where the scheduled policy was never purchased, or was not kept at the limit the schedule requires, there is no drop-down. The umbrella still attaches where the schedule says, and the difference between the two stays with your business. This is the single most misunderstood mechanic in the product.

What is a self-insured retention on a commercial umbrella?

A self-insured retention is an amount your business pays before the umbrella responds, and it applies where the umbrella covers something no scheduled policy covers. It is not a deductible, and the difference matters. Under a retention you fund the defense and the settlement yourself until the retention is satisfied. Under a deductible the insurer pays first and then seeks reimbursement from you. The policy’s retained limit is either the scheduled underlying limit or the retention, whichever applies to that particular claim. Confirm which one your form uses before assuming the umbrella pays from the first dollar of a claim it alone covers.

Does an umbrella cover anything my underlying policies exclude?

Sometimes, and less than most people expect. Where an umbrella is broader than the policies beneath it, the additional ground is narrow and it comes with a retention. It does not pick up an exposure the underlying policy excludes as a class. Professional liability, pollution, and any auto policy left off the schedule stay outside it. An umbrella also does not turn an uninsured exposure into an insured one, and insurers do not generally drop down over a risk a business chose not to insure at all. The question worth asking is what the umbrella’s own insuring agreement covers, not what the primary excludes.

How does an umbrella sit over workers compensation and employers liability?

Workers compensation is the exclusive remedy for a work injury in California under Labor Code section 3602. The exceptions are narrow. They cover a willful physical assault by the employer, fraudulent concealment of an injury, and injury caused by a defective product the employer made and sold to a third party outside the business. Employers liability, which is Part Two of the workers compensation policy, is what responds in the cases that fall outside the statute. An umbrella can add limits above employers liability. It never adds limits to statutory workers compensation benefits. Where an employer fails to secure the payment of compensation, Labor Code section 3706 allows the injured employee to sue at law as though the system did not apply.

How do California contracts decide the limit a business is asked to carry?

Contract requirements usually set the number, not your own sense of exposure. Caltrans ties the umbrella or excess limit to the size of the bid. The requirement runs from $5,000,000 on a $1,000,000 contract up to $25,000,000 above $25,000,000. The specification states that those limits are separate from and in addition to the general liability limits. The same specification requires a drop-down clause, additional insured status and primary and non-contributory wording. A contractor licensed as a limited liability company carries a statutory floor under Business and Professions Code section 7071.19. The floor is at least $1,000,000 of liability insurance for five or fewer personnel of record. It rises by $100,000 for each additional person, and is capped at $5,000,000. One point is often reversed. California’s anti-indemnity statutes, Civil Code section 2782 and section 2782.05, limit what you can be made to indemnify. They do not cap the insurance you can be required to buy, and section 2782.05 expressly preserves a contract term requiring you to carry insurance and additional insured endorsements covering your own acts.

Ready to look at it? Start a business insurance quote and send the schedule of underlying insurance from your current policies, or the declarations pages if you do not have a schedule. Tell us every entity name, vehicle and location that should be listed, because an unscheduled policy is the most common gap we find. If you are signing a contract, send us the insurance requirements page. We will tell you what limit it obliges you to carry, and whether your current schedule satisfies it. Some accounts we can write directly and quickly. Others go to underwriting for approval, or need a wholesale market, and those take longer. Either way you know before you decide.

Statutory references current as of September 2026 and specific to California. The contract limit figures are those in the Caltrans Revised Standard Specifications, cited as an example of how one California public agency sets its requirements rather than as a general rule. Coverage descriptions are general; the policy form controls.
