CSLB's website provides comprehensive information about applying for a state contractor license. As a condition of licensure, an applicant must take and pass law and business and trade examinations. (Exception: A trade examination is not required for the C-61 Limited Specialty classification.) Under certain conditions, a waiver of the examination(s) may be granted. Final determination as to whether the applicant meets the requirements for the examination or the criteria for the waiver is made during the application review process.
