Excess Liability & Umbrella Insurance for California Contractors

California contractor umbrella and excess liability: extra limits above GL, auto and employer's liability, when GCs require it, and what to check.

Quick answer: Umbrella or excess liability adds limits on top of your general liability, commercial auto and employer's liability policies. When a claim is larger than the primary limit, the excess policy pays above it. General contractors, property owners and public agencies often require $2 million to $5 million or more in total limits.

How it works

A primary general liability policy usually has a $1 million per-occurrence limit. A serious injury or a building-wide water or fire loss can exceed it. Excess liability sits above the primary policy and pays once that limit is used up. An umbrella can also cover some claims the primary policy does not, subject to its own terms. An excess policy generally follows the primary policy's terms.

Questions to ask before you buy

  • Can the excess sit over a primary policy written by another carrier, or only over its own? Some excess markets only follow their own underlying policy
  • Which underlying policies must be scheduled: GL, auto and employer's liability?
  • Does it have exclusions for residential tract, condo or wrap-up work, or for work in certain trades? These are common for contractors
  • Does the contract require the owner or GC as additional insured on the excess, and primary and non-contributory wording?
  • How much limit does the contract actually require? Buy the required limit, then compare the cost of the next million

Who needs it

Contractors who bid larger commercial or public jobs, work for developers or property managers, run vehicles on the road all day, or have contracts that set limits above $1 million. A single large claim can otherwise come out of the company's assets.

Frequently asked questions

What is the difference between umbrella and excess liability?

An umbrella can cover some claims the primary policy excludes, and sits above several policies. Excess generally follows the terms of the policy beneath it.

How much umbrella coverage does a contractor need?

At least what your contracts require. Many commercial and public contracts ask for $2 million to $5 million. Higher limits make sense for larger or riskier work.

Does umbrella cover workers' comp?

No. It can sit above employer's liability, but workers' compensation benefits are separate.

Can I buy an umbrella from a different company than my GL?

Sometimes. Some excess carriers will only sit over their own underlying policy, so ask before you buy.
