What you need to do to get your California contractors license active again
To reinstate a lapsed California contractors license, you must file a Reinstatement process (Form CSLB 228) with the Contractors State License Board (CSLB), pay the reinstatement fee, and meet the same requirements you faced when you first obtained the license. The process depends on how long your license has been inactive — if it lapsed fewer than five years ago, you can reinstate without retaking the exam; if it has been five years or longer, you must pass the current licensing exam again.
The CSLB does not automatically restore your license when you pay a fee. You are starting a formal reinstatement request that the board will review. The timeline from submission to approval typically runs four to eight weeks, though it can extend longer if the board requests additional documentation or if your record contains disciplinary history.
Key Takeaways
- File Form CSLB 228 (Reinstatement process) with the CSLB, along with proof of workers' compensation insurance and the reinstatement fee, which varies by license classification.
- If your license lapsed fewer than five years ago, you do not need to retake the exam; if it has been five years or longer, you must pass the Contractors License Exam for your classification.
- You must maintain active workers' compensation insurance coverage before the CSLB will process your reinstatement, and you need proof of that coverage in your process packet.
- The CSLB will deny reinstatement if you have outstanding disciplinary orders, unpaid fines, or unresolved complaints — check your record before you submit.
- Once reinstated, your license number remains the same, but your expiration date resets to four years from the reinstatement approval date.
Determining whether you need to retake the exam
The five-year rule is the dividing line. Count backward from today to the date your license lapsed or expired. If that span is fewer than five years, you move forward with Form CSLB 228 and the reinstatement fee only. If it is five years or longer, you must sit for the Contractors License Exam in your classification before the CSLB will process your reinstatement process.
The exam covers the California Building Code, the California Contractors License Law, and business and financial management practices specific to your trade. You register for the exam through the CSLB's testing vendor (currently Pearson VUE) and pay a separate exam fee on top of the reinstatement fee. Exam scheduling can take two to four weeks, so plan accordingly if you fall into this category.
If you are unsure of your lapse date, log into your CSLB account at cslb.ca.gov or call the CSLB at 1-800-321-2752 to confirm your license status and the exact date it became inactive.
Gathering the required documents and fees
You will need to submit Form CSLB 228, proof of active workers' compensation insurance, and payment. The reinstatement fee depends on your license classification and ranges from roughly $200 to $500; the CSLB website lists the exact amount for each classification. You can pay by check, money order, or credit card when you submit your process.
Workers' compensation insurance is non-negotiable. You must have a current policy in force before you submit your reinstatement request. The CSLB requires proof — typically a certificate of insurance or a policy declaration page showing your contractor license number, the policy period, and the carrier's name. If you do not have workers' compensation insurance, you cannot proceed; obtain a policy first, then file your reinstatement process.
If your license was subject to a disciplinary action, citation, or fine during its active period, gather documentation showing that any fines have been paid and any conditions have been satisfied. The CSLB will cross-check your process against its records, and unresolved disciplinary matters will block reinstatement.
Submitting your reinstatement process
Mail your completed Form CSLB 228, proof of workers' compensation insurance, and the reinstatement fee to the address listed on the form. The CSLB does not accept online reinstatement applications; all submissions must arrive by mail. Include a cover letter listing what you are enclosing so the board can verify completeness when it receives your packet.
The CSLB processes applications in the order received. Once your packet arrives, the board will send you a receipt showing the date received. If any document is missing or illegible, the CSLB will contact you by mail and ask you to resubmit. This delay can add two to four weeks to your timeline, so double-check your packet before you mail it.
Keep a copy of everything you send, including the cover letter and proof of mailing. If the CSLB loses your process or you need to follow up, you will have documentation of what you submitted and when.
What happens after you submit
The CSLB will review your process for completeness and verify your workers' compensation insurance status. If you passed the exam (or did not need to), the board will issue a reinstatement approval letter. Your license number stays the same, but your new expiration date becomes four years from the approval date.
Once approved, you can legally perform work under your license when ready. The CSLB will mail you a new wall certificate and pocket license card showing your updated expiration date. You do not need to wait for the physical cards to arrive before you work; the approval letter is your proof of reinstatement.
If the CSLB denies your reinstatement, the denial letter will explain the reason — usually unresolved disciplinary action, unpaid fines, or failure to pass the exam. You have the right to request a hearing before the Registrar if you disagree with the denial. The hearing request must be filed within 30 days of the denial letter.
Common reasons reinstatement is delayed or denied
The most frequent cause of delay is incomplete documentation. Missing workers' compensation insurance proof or an illegible copy of your policy can stall your process for weeks. The second most common issue is outstanding disciplinary fines or unresolved citations from before the license lapsed. The CSLB will not reinstate a license if you owe money to the board or have an open disciplinary case.
If you took the exam and did not pass, you must retake it and pass before reinstatement can proceed. You can sit for the exam again 30 days after your first attempt. Exam failure does not disqualify you from reinstatement, but you cannot move forward until you pass.
Occasionally the CSLB discovers that your workers' compensation insurance lapsed between the time you submitted your process and the time the board reviewed it. Insurance must be continuous and active on the approval date. If your policy expired, renew it when ready and notify the CSLB in writing with updated proof.
Reinstatement versus explore for a new license
Reinstatement is faster and cheaper than explore for a new license if your lapse is fewer than five years old and you have no disciplinary history. You keep your license number, and you do not retake the exam. A new process requires you to pass the exam, pay the full initial license fee (which is higher than reinstatement), and wait for processing as a new applicant rather than a returning licensee.
However, if your license lapsed more than five years ago, reinstatement and a new process are nearly equivalent in terms of time and exam requirement — both require you to pass the current exam. In that case, reinstatement may still be slightly cheaper, but the difference is small. Check the CSLB fee schedule to compare the exact costs for your situation.
Frequently Asked Questions
Can I work under my license while my reinstatement process is being reviewed?
No. Your license is inactive until the CSLB approves your reinstatement process and sends you the approval letter. Working without an active license is illegal and can result in fines and criminal charges. Wait for written approval before you take on any contracting work.
What if I cannot find my original license number?
Include your Social Security number or federal employer identification number on Form CSLB 228, and the CSLB will look up your record. You can also call the CSLB at 1-800-321-2752 to confirm your license number before you submit your process.
Do I need to renew my workers' compensation insurance policy before I submit my reinstatement process?
Your workers' compensation insurance must be active and current on the date you submit your reinstatement process. If your policy is set to expire soon, renew it before you mail your process. The CSLB will verify the policy is in force when it processes your request.
How long does reinstatement take if I do not need to retake the exam?
Four to eight weeks is typical from the date the CSLB receives your process to the date you receive approval, assuming your documentation is complete and there are no disciplinary issues. If the board requests additional information, add two to four weeks to that timeline.
What happens to my license expiration date after reinstatement?
Your new expiration date is four years from the date the CSLB approves your reinstatement. This is a fresh four-year cycle, not a continuation of your old expiration date. You will need to renew again four years after reinstatement approval.
