Complex Building Exam Prep

Master the full scope of the OBC Complex Building exam with a course built for results. Whether you’re preparing for your first attempt or looking to sharpen your knowledge, this course breaks down the most challenging sections of the Code into clear, exam-ready language.

Covering Division A compliance and objectives, Division B fire protection, environmental separation, HVAC, plumbing, housing provisions, renovation requirements, energy efficiency, and Division C administrative procedures — every article on the exam syllabus is explained in plain English with direct references to the 2024 Ontario Building Code.

What’s included:

Five professionally written workbook chapters that walk you through each section of the Code systematically — from building classification and fire-resistance ratings to exit requirements, barrier-free design, and permit procedures. Every article is broken down with real Code references so you know exactly what to study.

Five chapter quizzes (25 questions each) to test your understanding as you go, plus four full-length practice exams (70 questions each) that mirror the format and difficulty of the real thing. Every question includes a detailed explanation with the exact OBC reference, so you learn from every answer — right or wrong.

That’s over 400 unique practice questions, all mapped directly to the exam syllabus.
