C-46 Solar Contractors in California are one of the fastest-growing trades, and insurance requirements are strict due to the high value of solar installations and the risk of roof damage.
## C-46 Insurance Requirements
**General Liability:** $1M per occurrence minimum. Solar work on roofs requires higher limits — many project owners require $2M per occurrence.
**Workers' Compensation:** Generally relevant when employees are present; applicability depends on current California rules, ownership, classification, and business facts. Under SB 1455 Phase 2 (January 1, 2028), all C-46 contractors will be required to carry WC.
**Commercial Auto:** Required for work vehicles transporting solar panels and equipment.
**Contractor Bond:** $25,000 CSLB bond required.
## C-46 Insurance Cost
Typical monthly cost: pricing varies by classification, payroll, operations, claims history, limits, and underwriting/month for a full bundle. Solar contractors often need higher GL limits due to roof work.
