Before hiring any contractor in California, check these five items to protect yourself and your investment.

License is active
Required for any project over $1,000 in combined labor and materials.
Contractor bond is current
Protects you if the contractor fails to fulfill their obligations or violates CSLB regulations.
Workers compensation insurance on file
Without it, you could be liable if a worker is injured on your property.
No unresolved disciplinary actions
Check for citations, fines, or license suspensions that may indicate a pattern of violations.
Classification matches your project
A C-36 Plumbing license does not authorize electrical work. Confirm the right license type.
