Getting a contractor license in California can feel overwhelming, but with the right roadmap the process is straightforward. Whether you want to run your own construction business or qualify a company as its licensed contractor, this complete 2026 guide walks you through every step — from verifying your experience to passing the CSLB exam and activating your license.
Step 1: Determine Your License Classification
The California Contractors State License Board (CSLB) issues licenses in over 40 trade classifications. The three main categories are:
- A – General Engineering: highways, bridges, utilities, and other fixed works requiring specialized engineering.
- B – General Building: residential and commercial structures involving two or more unrelated trades.
- C – Specialty: 42 sub-classifications (C-2 Insulation, C-10 Electrical, C-36 Plumbing, etc.) for contractors working in a single trade.
Choosing the right classification matters because it defines the scope of work you can legally perform. If you’re unsure, check the CSLB’s classification chart or contact our licensing team for guidance.
Step 2: Meet the Basic Requirements
Experience
You need at least four years of journey-level experience in the classification you’re applying for. Acceptable experience includes work as an employee, foreman, contractor, or owner-builder. Education at an accredited trade school or college can substitute for up to three years of experience.
Age & Legal Status
Applicants must be at least 18 years old. There is no citizenship requirement — valid Social Security or Individual Taxpayer Identification Numbers are accepted.
Criminal Background
The CSLB conducts a background check. A criminal record does not automatically disqualify you, but certain convictions (especially fraud or financially related offenses) may require additional review.
Step 3: Submit Your Application
Complete the Application for Original Contractor License (Form 13A-1). You’ll need:
- Personal information and Social Security Number
- Detailed experience verification (employer names, dates, duties)
- Certification of work experience from a journeyman, contractor, or employer
- The non-refundable application fee of
Mail or submit the application online through the CSLB portal. Processing typically takes 6–10 weeks, though times may vary.
Step 4: Pass the CSLB Exams
Once your application is approved, the CSLB sends you exam scheduling instructions. Every applicant must pass two exams:
- Trade Exam — tests technical knowledge specific to your classification.
- Law & Business Exam — covers California contracting law, project management, safety, and business practices.
Both exams are multiple-choice, administered at PSI testing centers throughout California. You need a 72% or higher to pass each one. Our exam prep courses are designed to help you pass on the first attempt with practice questions pulled from real exam topics.
Step 5: Post Your Contractor Bond
After passing both exams, you must file a ,000 contractor bond (or a cash deposit). This bond protects consumers and is required by law. Most surety companies charge between and per year depending on your credit score.
Step 6: Obtain Workers’ Compensation Insurance (If Applicable)
If you plan to hire employees, you must carry workers’ compensation insurance before the CSLB will issue your license. Sole proprietors with no employees can file a Certification of Exemption instead.
Step 7: Receive Your License
Once the bond and insurance paperwork are on file, the CSLB issues your pocket license and wall certificate. Your license number will appear in the CSLB online database, and you’re legally authorized to bid and contract on projects in California.
How Long Does the Entire Process Take?
From application to active license, expect 3–6 months on average:
- Application processing: 6–10 weeks
- Exam scheduling & completion: 2–6 weeks
- Bond and insurance filing: 1–2 weeks
Delays usually happen when applications are incomplete or experience documentation is insufficient. Double-check everything before you submit.
