California Builders Risk Insurance

California’s Fire Hazard Severity Zone maps describe hazard rather than property-specific risk, and wildfire construction and defensible-space rules apply in defined areas. Verify the current local designation and project requirements, then ask how the quote addresses fire and smoke during each construction stage. 1,2

What Is Builders Risk?

Builders risk protects the project you are building, including materials meant for it, against physical loss until construction ends. The gaps that cost owners money are materials in storage or transit, the existing building in a renovation, and coverage ending when you occupy early. Read the national Builders risk guide.

What to Watch for in California

  • Verify the current fire-zone map

    CAL FIRE’s current maps classify fire hazard and expressly distinguish hazard from risk, which also depends on mitigation. Check the address using the applicable state or local map and tell the broker both the designation and the mitigation planned; the map does not set insurance availability or terms. 1

  • Check which wildfire rules apply to this site

    California OSFM describes wildfire construction and defensible-space measures and explains that requirements apply across State Responsibility Areas and Fire Hazard Severity Zone designations, with limited exceptions. Confirm the project’s local fire authority, applicable building requirements and evidence of compliance before the insurer’s inspection. 2,1

  • Ask about construction-stage fire and smoke terms

    Wildfire controls address ignition exposure around buildings, but they do not determine whether the policy covers a particular loss. Ask the broker to identify the quote’s fire, smoke, debris-removal and access provisions, any deductible or sublimit, and whether protection changes as the structure is enclosed or occupied. 2

Who Regulates Insurance in California

California Department of Insurance

The California Department of Insurance regulates insurers and insurance producers, provides company and license-status searches, and accepts complaints through its Consumer Complaint Center. Its commercial-insurance guidance explains the Department’s limited jurisdiction over surplus-line insurers. 5,6,7,8,18

Surplus-lines tax and stamping office

Reported tax rate: 3% of taxable premium when California is the insured's home state 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. 9,11,16,8,10,12,13,14,17

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. 10,13,14,3,4,19
  • 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. 11,15,16

Providers With Documented State Licenses

These providers publish a national listing for Builders risk; the state records document licenses for the entities and roles shown below. 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.

Builders Risk in California: FAQ

Do California Fire Hazard Severity Zone maps measure insurance risk? 1

CAL FIRE says its maps measure hazard based on physical conditions and expected fire behavior; risk also reflects current mitigation such as defensible space and ignition-resistant construction. The map does not decide coverage or availability. 1

Which California sites should check wildfire construction requirements? 2,1

OSFM describes applicability across State Responsibility Areas and Fire Hazard Severity Zone designations, subject to limited exceptions. Confirm the parcel’s current designation and requirements with the local authority. 2,1
