18% of Berkeley's B licensees hold more than one classification — most often C-10 Electrical Contractor (6%), C-36 Plumbing Contractor (5%). Extra classifications can change how carriers rate your general liability and workers' comp, so list every license class when you quote.
Business structure: 59% sole owners, 33% corporations, 6% LLCs; median time licensed 21.7 years.
For general contractors, underwriters focus first on: contract requirements: additional insured, waiver of subrogation, primary and non-contributory; and builder's risk on projects under construction. See the full coverage guide for general contractors for limits, endorsements and workers' comp rules.
