Quick Answer
California contractors working in CAL FIRE-designated high-fire and very-high-fire zones face surcharges on General Liability, Commercial Auto, Builder's Risk, and sometimes Tools & Equipment policies. Surcharges can add 25–100% to premium for projects in these zones. Some standard carriers decline outright. Call (858) 925-9555 — we shop specialty markets for wildfire-zone risk.
Which Zones Trigger Surcharges
- CAL FIRE Very High Fire Hazard Severity Zones (VHFHSZ)
- High Fire Hazard Severity Zones (HFHSZ)
- Wildland-Urban Interface (WUI) zones designated by local jurisdictions
- Brush-zone designations (Brush 1, 2, 3 in LA County)
Check your project address at osfm.fire.ca.gov (Cal Fire FHSZ Map).
What Carriers Surcharge or Exclude
- General Liability — many carriers add wildfire surcharges for roofing, demo, and brush-clearing work in fire zones
- Builder's Risk — surcharges of 25%+ common; outright exclusions for projects in extreme zones
- Commercial Auto — minor surcharges based on garage location
- Tools & Equipment — usually unaffected
Trade-Specific Impact
- C-39 Roofing: ember-resistant materials required by code in many fire zones; carriers ask about installation specs
- C-27 Landscape: defensible space work brings fire-risk attention from underwriters
- Demo/Tree work: spark-source risk drives high GL rates
Risk Management Steps
- Document spark-control protocols for hot work (welding, grinding, demo)
- Carry approved fire extinguishers on every truck and job site
- Verify property owner's defensible space before starting work
- Avoid red-flag warning days for hot work where possible
