California does not hand out contractor licenses casually. The requirements cover who you are, what you know, who vouches for your experience, and how you protect the public financially. Here is the complete checklist, in the order you will actually deal with it.
1. Experience: 4 years at journey level
Your qualifier needs 4 years of journey-level experience in the classification being applied for, earned within the last 10 years. Journey level means you can perform the work of the trade without supervision, not that you watched it being done. The experience must be in the actual classification you are applying for; plumbing experience does not qualify you for an electrical license.
Document everything: employers, dates, scope of work, and people who can verify it. The CSLB reviews the experience claimed on the application, and thin documentation is one of the most common reasons applications stall. If you are working through the full licensing steps, this is the part to start on first, because it takes the longest to assemble.
2. A qualifier: RME or RMO
Every license needs a qualifying individual: a responsible managing employee (RME) or responsible managing officer (RMO). The qualifier is the person whose experience and exam results back the license, and the qualifier must genuinely supervise the work.
The rules have teeth. An RME must work at least 32 hours per week or 80% of the business's hours, whichever is less. A qualifier can only qualify a limited number of firms, and lending a license to companies you do not actually supervise is a misdemeanor. If your qualifier disassociates from the license, written notice is due within 90 days and a replacement qualifier must be in place within 90 days, with one 90-day extension available for good cause. Miss the window and the license suspends.
3. The right classification
You must apply in a classification that matches the work you will perform: A (general engineering), B (general building), B-2 (residential remodeling), or one of the C specialties. A B license requires work in at least 2 unrelated trades. The B-2 requires at least 3 unrelated trades and cannot include structural work. Picking the wrong classification wastes the application fee and months of time, so choose carefully before you file.
4. The application and the $450 fee
The original license application carries a $450 fee for one classification. The application is where the CSLB reviews your experience, your qualifier, and your classification choice. Once accepted, an 18-month clock starts: you must pass your required exams within 18 months or the application goes void and you pay again.
5. Two exams
Almost every applicant takes two exams: the trade exam for the classification and the Law and Business exam. Both are closed book, computer-based at PSI test centers, 3.5 hours each. Each exam registration costs $51.43, paid to PSI, nonrefundable.
Two exceptions are worth knowing. Reciprocity with certain states can waive the trade exam, but it never waives the Law and Business exam. And no exam is required at all if your qualifier passed the same classification exam, or qualified a license in good standing in the same classification, within the last 5 years.
Fail an exam and you wait 21 calendar days to retake it. Exam results are good for five years.
6. The $25,000 contractor bond
A $25,000 contractor license bond is required to get and keep the license, in effect since January 1, 2023. If your qualifier owns less than 10% of the business entity, a separate $25,000 qualifier bond is also required. The old $15,000 figures you may see in older materials are obsolete.
LLC licensees carry extra requirements: a $100,000 surety bond for employee wage claims, plus liability insurance of $1,000,000 aggregate for five or fewer listed persons (scaling up to $5,000,000 for larger firms).
A bond is not insurance for you. It is a financial guarantee that protects consumers and the state if you violate contracting law. And it is illegal to advertise that you are bonded, so do not put it on your truck.
7. Workers compensation insurance
If you have employees, workers compensation coverage is mandatory, no exceptions. A few specialty classifications cannot claim the no-employee exemption at all. Letting coverage lapse means automatic suspension of the license, and operating without required coverage is cause for discipline. This is not an area where close counts.
8. The license fee
After exams are passed and bond and insurance are verified, you pay the initial license fee: $200 for a sole owner, $350 for every other business type. The license term is 2 years. An expired license can be renewed within 5 years, but a delinquency fee of 50% of the renewal fee applies, so renew on time.
9. Ongoing obligations
Getting licensed is the start of the compliance list, not the end:
- Report changes within 90 days. Address, business name, and personnel changes must be reported to the CSLB in writing within 90 days.
- Put your license number on everything. Contracts, subcontracts, bids, and advertising must show your license number.
- Follow the home improvement contract rules. Any home improvement contract over $500 must be in writing with specific required contents. Down payments are capped at $1,000 or 10% of the contract price, whichever is less. Buyers get 3 business days to cancel (5 for seniors, 7 for disaster repair).
- Pay your subs on time. Each subcontractor must be paid within 7 days after you receive each progress payment, unless you agreed otherwise in writing. Wrongful withholding costs 2% per month.
Common disqualifiers and delays
Most applications that stall do so for preventable reasons: experience that cannot be documented, a qualifier whose hours do not meet the threshold, the wrong classification, or an incomplete application. Criminal history is reviewed, but it is not an automatic bar; the CSLB looks at the nature of the offense and its relationship to contracting. Be accurate and complete on the application. Omissions cause more trouble than the underlying facts.
