CSLB Law & Business — Complete Study Guide (2026)

Since January 1, 2025 the California license-free job limit is $1,000, not $500 (B&P §7048, AB 2622). This book is written to the rest of current law the same way: the $25,000 bond, the 2026 fee table, the July 2026 penalty ranges, and CSLB's January 1, 2027 deadline to verify workers'-comp exemptions. All 7 exam sections, plus a 115-question practice exam timed to CSLB's published 3½ hours, with answers at the back. PDF + EPUB.

CSLB Class B General Building — Trade Exam Study Guide (2026)

Written to the 2025 California codes in force since January 1, 2026 — guards are now CRC R321, stairs R318.7 — and to Cal/OSHA's 6-foot residential framing fall-protection rule, operative July 1, 2025. The CSLB Class B General Building trade exam (the craft half, separate from Law & Business): planning & estimating, framing & structural, core trades, finish trades and safety, with 64 worked examples, a 130-question mixed practice exam to sit in CSLB's 3½ hours, and 270 more questions in five chapter practice sets — 400 in all, weighted to CSLB's published section weights. Follows CSLB's General Building (B) study guide, form 13E-B (03-2026). Exam review for working builders, not a first introduction: CSLB requires documented journey-level experience before you can sit the exam, and the book assumes that background. Appendix B flags every figure that can change with the code edition or local amendment. AI-assisted study aid. PDF + EPUB.
