Quick answer
How to Get a Contractor License in California (2026 Step by Step)
To get a California contractor license: prove four years of journey-level experience, choose your classification, file the $450 CSLB application, complete Live Scan, pass the Law and Business exam plus your trade exam at PSI, then post a $25,000 bond and pay the license fee. Plan on two to four months start to finish.
Most people hit the same three walls, in this order: proving four years of experience, passing two exams on the same day, and posting a bond before the license issues. This guide walks the sequence the Contractors State License Board (CSLB) actually uses, so you are not paying fees out of order or waiting on a step you could have started earlier.
- 4 years
- Qualifying experience journey-level, last 10 years
- 2 exams
- Law and Business + trade in person at PSI
- 2 to 4 mo.
- Typical time to license filing to active
The six steps, in order
You do these in sequence, and doing them out of order costs you time. Here is the whole path at a glance before we break each step down.
-
Confirm you qualify
Four years of journey-level or higher experience in your classification, within the last ten years, certified by someone who can vouch for it.
-
Choose your classification
A specific class, not a generic contractor license: Class A engineering, Class B general building, or a single C-series trade.
-
Submit the Original Application
File with CSLB and pay the application fee. Nonrefundable, separate from the license fee, and the number one source of delay when incomplete.
-
Get fingerprinted (Live Scan)
A DOJ and FBI background check. Results must be on file before a license issues, so book it the same week you apply.
-
Pass the two exams
Two closed-book, computer-based exams at a PSI center in one appointment, once CSLB approves your application.
-
Post your bond and pay the license fee
File a $25,000 contractor bond and pay the initial license fee before the license activates.
1. Confirm you qualify before you pay anything
California requires at least four years of journey-level, foreman, supervising, or contractor experience in the classification you are applying for, gained within the last ten years. Journey-level means you worked at the skill level of a fully qualified worker, not an apprentice. Some technical training or an approved degree can offset up to three of those four years, but you always need at least one year of hands-on experience.
Your experience has to be certified by someone who can vouch for it: a current or former employer, a licensed contractor, a supervisor, a building inspector, or a fellow journeyman. CSLB audits a share of applications, so the person signing must be reachable and willing to confirm your dates and duties.
2. Choose your classification
You apply for a specific classification, not a generic contractor license. Class B (General Building) covers projects involving two or more unrelated trades. Class A (General Engineering) covers fixed works like grading, pipelines, and roads. The C-series covers single trades: C-10 Electrical, C-36 Plumbing, C-20 for warm-air heating and air conditioning, and dozens more. See our classifications guide if you are unsure which one fits your work, because you sit the trade exam for the class you applied for.
3. Submit the Original Application
File the Application for Original Contractor License with CSLB and pay the $450 application fee (one classification). This fee is nonrefundable and separate from the license fee you pay later. Include your certified experience, your Live Scan arrangement, and, if you are not a sole owner, your entity details. Processing takes several weeks, and incomplete applications are the number one cause of delay. Total your real out-of-pocket first with the California license cost breakdown.
4. Get fingerprinted (Live Scan)
Everyone on the license gets a criminal background check through the California Department of Justice and the FBI. You complete a Live Scan at an approved location, and the rolling fee plus the state and FBI fees usually total about $70 to $90. Do this early, because results have to be on file before a license issues. It is the cheapest step to get wrong and the easiest to knock out immediately.
5. Pass the two exams
Once CSLB approves your application, you are scheduled at a PSI test center for two closed-book, computer-based exams in the same appointment: the Law and Business exam that every applicant takes, and the trade exam for your classification. See our Law and Business exam guide for the blueprint and our exam day guide for what to bring and what happens if you fail one section.
6. Post your contractor bond and pay the license fee
Before the license activates you must file a $25,000 contractor bond with CSLB. The bond is not insurance for you: it protects your customers, and you buy it from a surety for a yearly premium that depends on your credit, commonly $100 to $400 a year. You also pay the initial license fee: $200 for a sole owner, $350 for a non-sole owner (partnership, corporation, or LLC). LLCs carry an additional $100,000 worker bond and a liability-insurance requirement.
How long does the whole thing take?
Plan on roughly two to four months from filing to an active license: several weeks for CSLB to review the application, then scheduling and sitting the exams, then posting the bond. The two levers you control are submitting a complete, correctly certified application and getting Live Scan done immediately. Everything downstream waits on those.
