Summary
Operating as a concrete contractor in Santa Rosa, California requires both state and local compliance. At the state level, you must obtain a C-8 Concrete license from the California Contractors State License Board, which involves demonstrating 4 years of experience, passing required exams, and maintaining continuing education. Local requirements include a Santa Rosa business license and building permits for most concrete work through the city's Building Division.
