    • Enforces the rules that contractors have to follow.

    Did you know that the Contractors State Licensing Board publishes guides on hiring a contractor? Here are some key takeaways:

    • If a contractor charges $500 or more, they must be licensed.

    • Any changes to the contract or change orders, "need to be in writing and signed" by both you and the contractor.

    Don't forget to always check a contractor's license before getting work done!

    What types of complaints does the California Contractors State License Board handle?

    The Contractors State License Board handles a broad range of complaints against contractors. Here are some examples:

    • When a contractor damages your home.  

    • When you hired a contractor to fix something in your home but they didn't fix it.

    • When you paid the contractor but they didn't perform the work.

    Note: the CSLB cautions that "If your primary interest is to recover the money you paid to a contractor, you should consider civil action.

    If you're considering legal action to recover damages of $12,500 or less, CSLB may provide you with information to help you file a small claims court action.
