Contractor’s General Building CSLB B Exam Study Guide 2026–2027 | 200 Practice Questions

Prepare for the California General Building (B) contractor trade examination with a complete, illustrated study guide organized around the five sections of the current CSLB examination outline: Planning and Estimating, Framing and Structural Components, Core Trades, Finish Trades, and Safety.

This 136-page digital guide is written from the California building, residential, plumbing, electrical, mechanical, energy and green building codes and the Cal/OSHA safety orders, the same references the examination draws on. Each of the 28 chapters gives you the dimensions, spacings, clearances, sequences and formulas the questions ask for, with tables, labeled diagrams and worked calculations, followed by two 100-question practice tests written at examination level.
