California Contractor Law and Business Exam Prep 2026: Free Practice Questions by Topic

Why study the California exam by topic

The California Law and Business exam is not a test of construction skill. It is a test of the rules that govern running a licensed contracting business in this state, and almost every scored item traces back to a specific statute. If you read the whole Contractors State License Law front to back you will drown in detail, because Chapter 9 alone runs from Business and Professions Code section 7000 to well past section 7191, and the workers' compensation, wage and prevailing-wage rules sit in an entirely separate code. Studying by topic fixes that. Each guide below isolates one area the exam tests, tells you which statute controls it, and lets you drill free practice questions until the rule sticks. You spend your time on the handful of facts the exam actually asks about instead of memorising the code cover to cover.

The six topics the exam covers

Each guide answers the real questions California candidates ask, explains the governing statute, gives you a comparison table for the points people confuse, and lets you try free practice questions drawn from the same offline app question bank. Together they walk the whole Law and Business syllabus:

• Licensing and the CSLB: who must be licensed, the three classifications, exemptions, the qualifying individual, and applying for and keeping a licence under B&P Code sections 7000 to 7145.5.
• Employment and payroll: the workers' compensation certificate the CSLB demands, final-pay timing and the waiting-time penalty under B&P Code section 7125 and Labor Code sections 200 to 246.
• Bonds, insurance and liens: the $25,000 contractor's bond, the disciplinary and qualifying-individual bonds, and the mechanics lien process under B&P Code sections 7071.5 to 7071.9 and Civil Code section 8400.
• Home improvement contracts: the $500 threshold, the mandatory contract terms, salesperson registration and cancellation rights under B&P Code sections 7151 to 7159.
• Public works and prevailing wage: what counts as a public work, the de minimis subsidy test and DIR registration under Labor Code sections 1720 to 1743.
• Cal/OSHA safety: the employer's safety duties, the Injury and Illness Prevention Program and the construction safety orders under Labor Code sections 6300 to 6409 and Title 8 of the California Code of Regulations.

How the exam is graded and what it draws on

The Contractors State License Board administers two exams to most applicants: a trade exam for the specific classification, and this Law and Business exam that every applicant sits regardless of trade. The Law and Business content is stable because it is tied to enacted statute, which is why studying the code pays off. Protection of the public is the board's stated highest priority under Business and Professions Code section 7000.6, and that principle runs through the whole syllabus: the bond protects consumers and workers, the workers' compensation rule protects employees, the home improvement contract rules protect homeowners, and the Cal/OSHA orders protect everyone on the jobsite. When a question seems to have two defensible answers, the one that better protects the public is usually the tested answer. Keep that lens in mind as you work each topic.

Check your readiness, then go deeper

Not sure where you stand? Work the free practice questions on each topic page to find your weak areas, then drill them until the statute and the number both feel automatic. The exam loves precise figures: the $25,000 bond, the $7,500 aggregate cap on non-subdivision beneficiaries, the $500 home improvement threshold, the 72-hour final-pay window, the 10-day stop-order pay rule, the three-working-day serious-complaint deadline. Each topic page exposes a slice of the same question bank that powers our offline California app, so you can sample the real difficulty for free before you unlock the full set. Every fact here is taken from the public text of the California statutes and regulations, which are public-domain government edicts, and was last reviewed for 2026. Treat this hub as your citable starting point and verify any deadline or fee against the Contractors State License Board before you act on it.
