What should a California contractor prepare for a business insurance review?

Prepare the business name, license or trade information, employee and payroll details, operations, vehicles or equipment when relevant, contracts, prior coverage, and claims history. A licensed team member can then review the request subject to carrier eligibility, policy terms, and underwriting.

How are business insurance limits or terms selected for a contractor?

Limits and terms are not universal. They can be influenced by the contractor's actual work, contracts, employee duties, vehicle use, project requirements, prior loss history, carrier guidelines, and applicable California requirements. The appropriate structure must be reviewed for the individual operation.

C-10 Electrical License and Insurance Requirements

Quick Answer

C-10 Electrical Contractors install, alter, and repair electrical wiring, fixtures, and equipment in California. Required: active CSLB license, WC under SB 216 (Class 5190 — pricing varies by classification, payroll, operations, claims history, limits, and underwriting/$100), $25K license bond, and GL ($1M/$2M minimum). Total annual insurance for a small crew: pricing varies by classification, payroll, operations, claims history, limits, and underwriting. Call (858) 925-9555.

What C-10 Covers

Electrical wiring (residential and commercial)
Fixtures and equipment installation
Service upgrades
Some solar interconnect work
Low-voltage and high-voltage as the license scope allows

Mandatory Insurance

WC (mandatory under SB 216 for most operations)
$25K license bond
GL ($1M/$2M minimum required by most GCs)

Risk Profile

Arc flash — high-voltage incidents cause severe burns and electrocution
Completed operations — wiring errors discovered months later cause fires
Fall risk — overhead work in attics and on lifts

A common gap: standard GL excludes design errors. C-10s doing design-build need Professional Liability/E&O — see our E&O guide.
