California Umbrella and Excess: Price the Caltrans Project Tier

Caltrans’s revised August 2025 construction guidance requires an umbrella or excess layer with project-specific liability coverage and directs bidders to the special provisions for complete terms. For emergency contracts, a May 2024 directive ties the umbrella amount to bid size, from $5 million through $25 million. Build the quote from the current contract tier and endorsements, not from a statewide rule for all businesses.

What Is Umbrella and Excess Liability Insurance?

Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. Read the national Umbrella and excess liability guide.

California Umbrella and Excess Liability Insurance Requirements

Requirement	Details
Caltrans construction documentation	Caltrans’s August 2025 construction guidance says the specific contract’s special provisions control. Successful bidders submit the CGL and excess/umbrella policy or interim binder, declarations and applicable endorsements; an SIR over $50,000 needs a CPA declaration. For the listed Caltrans specifications, umbrella/excess must drop down if primary limits are impaired or exhausted, and its required limit sits separately from and in addition to GL. ¹
Emergency contract umbrella tier	Caltrans’s emergency directive assigns $5 million for bids up to $1 million, $10 million for bids over $1 million through $10 million, $15 million through $25 million, and $25 million above $25 million. The directive requires resubmission if an estimate change moves the project to a different tier. ²
Workers’ compensation context	California requires employers with one or more employees to provide workers’ compensation benefits; the Department of Industrial Relations notes a special roofer rule even without employees and possible coverage for out-of-state employers with regular California employees or an employment contract made there. ³

What to Watch for With Umbrella and Excess Liability in California

Recheck the tier when the estimate changes
The emergency directive requires updated insurance approval if the engineer’s estimate moves the job to another limit band. Confirm the latest estimate and approval before binding or accepting a certificate. ²
Submit the policy wording with the certificate
Caltrans requests the CGL and umbrella/excess policy or interim binder, endorsements, riders and modifications. Its August 2025 specification says excess must drop down when primary limits are impaired or exhausted, sit separately from and in addition to GL, and avoid exclusions that bar follow-form coverage for the required coverages; it also calls for annual reinstatement during construction. Compare these clauses with the actual policy wording, not just the certificate. ¹
Budget the retention and keep statutory WC separate
A Caltrans SIR over $50,000 triggers the specified CPA declaration. Workers’ compensation has separate state rules, including the roofer and out-of-state qualifications; an umbrella quote does not establish WC compliance. ^1,³

Providers With California License Records

These providers publish a national listing for Umbrella and excess liability; the license records below name the licensed entities and roles. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in California. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

Who Regulates Insurance in California?

California Department of Insurance

Surplus-Lines Tax and Stamping Office in California

Reported tax rate. 3% of taxable premium when California is the insured's home state ^10,^12,^17,^9,^11,^13,^14,^15,¹⁸

When California is your home state, the surplus-line broker tax is generally 3% of gross premiums less returned premiums. Ask the broker to show the home-state determination, taxable premium and any applicable exception; ordinary multistate reporting does not itself reduce the tax base. A broker generally must search the admitted market unless a California exemption or the qualified federal commercial-purchaser exception applies. CIGA does not protect claims under a surplus-line policy.

Surplus Line Association of California

California usually requires an admitted-market search: Before most nonadmitted placements, a broker must search among admitted insurers. After a public hearing and the required statutory findings, California’s Commissioner may exempt qualifying coverage or risks through an Export List order. The confidential written report remains required under §1763.1. Separately, §1763(h) waives the search for a commercial insured meeting California’s §1760.1(b) definition: the broker must first give written disclosure about possible admitted-market availability and its potential greater protection and oversight, then receive the insured’s written request for nonadmitted placement. The broker must ensure eligibility, with a safe harbor for reasonable reliance on information supplied in good faith. The federal exempt-commercial-purchaser route under §8205 has its own §8206 definition and requires disclosure about possible admitted-market availability and its potential greater protection and oversight, followed by the purchaser’s written request. Ask which route and eligibility criteria the broker relies on. ^11,^14,^15,^4,^5,²⁰
Separate tax calculation from allocation reporting: Section 1775.5 generally counts the entire premium for nonadmitted insurance placed in one transaction with one underwriter or group for a California-home-state insured. It has a separate interstate-motor-transit formula and exclusions for premiums on insurance placed by or through a special-lines surplus line broker under §1760.5 and the defined risk-financing portion of specified Superfund remediation products. CDI’s calendar-year 2025 instructions include policy-related fees in gross premium, say it does not collect the tax on risks outside the United States, and treat multistate allocation percentages as informational. Have the broker explain how those rules apply to your placement. ^12,^16,¹⁷

Questions to Ask Before You Buy Umbrella and Excess Liability in California

Which Caltrans contract type and current estimate set the applicable umbrella tier, and has the emergency approval package been accepted?
Can the excess carrier provide the required annual reinstatement, products/completed operations and contractual-liability terms without conflicting exclusions?
If the SIR exceeds $50,000, who will provide the CPA declaration and evidence of funds before the contract deadline?
Does the umbrella drop down when an underlying limit is impaired or exhausted, and are its limits separate from and in addition to the required CGL limits?

Umbrella and Excess Liability Insurance in California: FAQ

Does California require all businesses to carry a $5 million umbrella?

The cited dollar tiers are for Caltrans emergency contracts. They are not a general state rule for every business; use the terms in your particular contract. ²

What if our Caltrans self-insured retention exceeds $50,000?

The Caltrans guide asks for a CPA declaration under penalty of perjury that GAAP guidelines were applied and that the bidder has sufficient funds and resources to cover the retention. Confirm current submission details with the project office. ¹
