What happens when your California contractors license lapses
A California contractors license becomes inactive when you do not renew it before the expiration date printed on your card. Once it lapses, you cannot legally work as a contractor in California — even if you were licensed for years. The good news is that reinstatement is usually simpler than getting a license from scratch, because you have already passed the exams and met the original requirements.
The Contractors State License Board (CSLB) handles reinstatement. The process depends on how long your license has been expired. If it expired less than two years ago, you can reinstate it by paying a fee and submitting a form. If it has been expired for two years or longer, you will need to retake the law and business exam, though you do not need to retake the trade exam.
Key Takeaways
- Licenses expired less than two years can be reinstated by submitting Form CSLB 1 (Renewal/Reinstatement process) and paying the reinstatement fee, which varies by license classification.
- Licenses expired two years or longer require you to retake the Contractors Law and Business exam before reinstatement is approved.
- You must submit your reinstatement request directly to the CSLB by mail or through their online system; there is no third-party reinstatement service.
- Processing time for reinstatement typically takes four to six weeks after the CSLB receives your complete process.
- If your license was suspended or revoked (not just expired), reinstatement requires a formal hearing and is a different process entirely.
Reinstatement within two years of expiration
If your license expired within the last two years, you can reinstate it without retaking exams. You will need to complete Form CSLB 1 (Renewal/Reinstatement process), which you can read from the CSLB website or request by mail. On the form, you will declare that you have not engaged in any unlicensed contracting work since the license expired.
The reinstatement fee depends on your license type. A Class A (general engineering contractor) or Class B (general building contractor) license costs more to reinstate than a Class C (specialty contractor) license. Check the CSLB fee schedule on their website for your specific classification, as fees change periodically. You will also need to include proof that you have current workers' compensation insurance or a valid Certificate of Exemption if you have no employees.
Mail your completed Form CSLB 1, the fee, and your insurance documentation to the CSLB address listed on their website. You can also submit the process through the CSLB online portal if you have set up an account. Once received, the CSLB will review your process and send you a new license card by mail.
Reinstatement after two or more years of expiration
If your license has been expired for two years or longer, you must retake the Contractors Law and Business exam before the CSLB will reinstate you. You do not need to retake your trade exam (the technical exam for your specific license class). This requirement exists because California law changes, and the CSLB wants to may support you are current on legal and regulatory requirements.
To prepare for the exam, you can purchase study materials from the CSLB or use third-party study guides. The exam covers California contractor law, business practices, workers' compensation, and licensing regulations. You will schedule the exam through a testing vendor — the CSLB website lists approved testing locations and dates. After you pass the exam, you will receive a passing score report.
Once you have your passing score, submit Form CSLB 1 along with the score report, the reinstatement fee, and proof of workers' compensation insurance. The CSLB will then process your reinstatement. This path takes longer overall because you must schedule and pass the exam before submitting your reinstatement process.
Documents and information you will need
Before you start the reinstatement process, gather these items. You will need your original license number (or your Social Security number if you do not have it), your current mailing address, and a phone number where the CSLB can reach you. Have your workers' compensation insurance policy number or Certificate of Exemption ready — the CSLB will verify this information directly with your insurance carrier or the state.
If you have moved since your license expired, update your address with the CSLB before submitting your reinstatement process. If your name has changed, you will need to provide legal documentation of the change (such as a marriage certificate or court order). If you have any outstanding citations, complaints, or disciplinary actions from the CSLB, those must be resolved before reinstatement can be approved.
Suspension and revocation are different from expiration
If your license was suspended or revoked by the CSLB (rather than straightforward expired), reinstatement is a different and more complex process. Suspension means your license is temporarily inactive, usually because of a violation or complaint. Revocation means the CSLB permanently cancelled your license. You can tell the difference by checking your CSLB record online or calling the CSLB directly.
If your license was suspended, you may be able to request reinstatement once the suspension period ends or conditions are met. If it was revoked, you will need to request a hearing before the CSLB to argue for reinstatement. Both of these paths require legal documentation and often involve an attorney. Contact the CSLB directly to understand what happened to your license and what steps are available to you.
How to submit your reinstatement request
The CSLB accepts reinstatement applications by mail or through their online licensing system. To mail your process, send Form CSLB 1, your fee, and supporting documents to the address listed on the CSLB website. Include a cover letter with your name, license number, and a brief note stating that you are requesting reinstatement. Keep copies of everything you send.
If you use the online system, you will need to create an account on the CSLB website if you do not already have one. Log in, select "Reinstatement" from the process type menu, and follow the prompts. You can upload documents directly and pay the fee online using a credit card or electronic check. The online method is usually faster because you receive a confirmation number when ready and can track your process status.
After you submit your process, the CSLB typically sends a confirmation email or letter within a few business days. Processing usually takes four to six weeks. You can check the status of your process on the CSLB website using your process number or license number. If the CSLB needs additional information, they will contact you by phone or mail.
What to do while you wait for approval
Once you have submitted your reinstatement process, you cannot legally perform contracting work under a California license until your new license is issued. If you need to work before reinstatement is complete, you have limited options. Some contractors work as an employee under another licensed contractor's license, or they perform work that does not require a license (such as labor-only work). Check with the CSLB about what work is permitted in your situation.
If you have clients or jobs waiting, let them know your timeline. Most clients understand that reinstatement takes several weeks. If you need your license urgently, contact the CSLB to ask if expedited processing is available — it is not may provide, but the CSLB may be able to prioritize your process in certain circumstances.
Frequently Asked Questions
Can I work as a contractor while my reinstatement is being processed?
No. Once your license expires, you cannot legally perform contracting work in California, even if your reinstatement process is pending. Working without a valid license can result in fines and criminal charges. You must wait until your new license is issued and arrives in the mail.
Do I have to retake both exams if my license expired more than two years ago?
No. You only retake the Contractors Law and Business exam. Your trade exam (the technical exam for your license class) does not need to be retaken. This is because the law and regulations change more frequently than the technical requirements of your trade.
What if the CSLB denies my reinstatement process?
The CSLB will send you a written explanation of the denial. Common reasons include incomplete paperwork, lack of workers' compensation insurance, or a disciplinary issue on your record. You can request a hearing to appeal the denial, or you can reapply once you have addressed the issue.
How much does reinstatement cost?
The fee varies by license class and changes periodically. Class A and B licenses cost more than Class C licenses. Check the CSLB fee schedule on their website for the current amount for your license type. You will also need to provide proof of workers' compensation insurance, which is a separate cost from the reinstatement fee.
Can I reinstate my license if I owe money to the CSLB?
If you owe fines, penalties, or other money to the CSLB, you will need to pay those amounts before reinstatement can be approved. Contact the CSLB to find out what you owe and how to pay. Once the debt is settled, you can proceed with your reinstatement process.
