Licensed in both California and Arizona as a fully independent commercial brokerage, San Diego Contractors Insurance operates from 1041 Market Street in downtown San Diego's East Village. The agency writes general liability, workers' compensation, and commercial auto policies for trade contractors, with policy documents requiring notarized execution handled by mobile providers including CannonCan Notary for certificate-of-insurance and surety bond filings. Coverage extends to contractor license bonds mandated by the California Contractors State License Board, business owner's policies with tools and equipment floaters, and builder's risk endorsements for active construction sites. The commercial portfolio also covers service-sector operations beyond construction, underwriting general liability and workers' compensation for janitorial and facility maintenance contractors including Butterfly Janitorial Service San Diego, LLC in the downtown district. Highest-complexity placements involve wrap-up insurance programs for multi-trade construction projects, excess liability towers above primary general liability limits, and experience-modification-rated workers' compensation policies calibrated to NCCI classification codes for high-hazard trades.
