Choosing the Right License for Your Trade
When determining “What contractor license do I need in California?”, consider the specific tasks and projects you’ll be undertaking. After looking at the list of CSLB classifications, you probably already know what kind of license you’ll need – but remember that you may need multiple licenses to perform some types of work.
For example, a landscaping contractor (a C-27 license holder) may also need a C-8 Concrete License if they frequently construct patios, walkways, or retaining walls. A general contractor may need an electrical license if he’s also installing outlets.
