How to Add a Classification to an Existing Contractor License
How to add another classification to your California contractor license, what it costs and when the exam can be waived.
Quick answer
Your license must be current and renewed. Choose a qualifier for the new classification, document four years of experience in it from the last ten years, and submit the Application for Additional Classification with the $230 fee. The qualifier must pass the trade exam unless CSLB grants a waiver.
Steps to Add a Classification
- Make sure your existing license is renewed and current.
- Select a qualifying individual for the new classification. It can be your current qualifier or a new one.
- Have the qualifier describe four years of journey level experience in the new classification within the last ten years, with work certifications.
- Include any education or apprenticeship documents for credit.
- Submit the Application for Additional Classification with the $230 fee to CSLB Headquarters.
- File any bonds that are required.
Exams for an Added Classification
The qualifier must have passed the Law and Business exam and the trade exam for the new classification. If the qualifier already passed the Law and Business exam, typically only the trade exam is needed.
When the Exam Can Be Waived
- The person is currently the qualifier for a license in good standing in the same classification
- The person was a qualifier in the same classification within the last five years on a license in good standing
- The person passed both exams in the same classification within the last five years
Waivers are at the Registrar’s discretion. In some of these cases you also do not need to document experience.
Adding C-61 Categories
All C-61 Limited Specialty categories can be requested on one application. C-61 has no trade exam. See the C-61 license guide.
If Your Qualifier Is an RME
If the new qualifier is an RME who holds an individual license, that license must be inactivated, because an RME cannot be active on more than one license. See RMO vs RME.
