48% of San Diego's C-20 licensees hold more than one classification — most often C-36 Plumbing Contractor (26%), B General Building Contractor (26%). Extra classifications can change how carriers rate your general liability and workers' comp, so list every license class when you quote.
Business structure: 27% sole owners, 62% corporations, 10% LLCs; median time licensed 9.5 years.
For HVAC contractors, underwriters focus first on: service vans driven daily across a wide territory; and heat illness and falls working in attics and on rooftops. See the full coverage guide for HVAC contractors for limits, endorsements and workers' comp rules.
