2. How to study for the residential building plans examiner (R3) exam


Knowing how to tackle answering questions from all of the required sections is a daunting task. Practicing answering building code questions is essential for a plans examiner or someone about to take an exam. In the office, a plans examiner should be able to answer general questions about occupancy, means of egress, fire protection requirements, and structural elements and their associated rating requirements. During an exam, test takers must be able to navigate the International Residential Code fast enough to answer all of the questions within the allowed time of 120 minutes.

3. How to take the ICC residential building plans examiner exam


When taking a building code examination, it is essential to be able to navigate the code fast enough to find all of the answers in the text. Most ICC examinations are open book and because of this, obscure and hard to memorize material will be included in all of the examinations i.e. large tables and mathematical formulas. The 2018 residential building plans examiner exam requires applicants to be able to answer the following questions in the allocated time:


  • Number of questions: 60

  • Time limit: 2 hours


This means that examinees will have roughly four minutes per question. It may appear as a generous amount of time but some questions will be longer and more in depth than others which requires a plans examiner to be able to have section locations of the books memorized. Having chapter locations memorized and pacing oneself will lead to passing the exam. Practice exams from Building Code Masters prepare test takers for the time crunch and memorization of the most important sections of the code. Whether the exam is focused on building, mechanical, electrical, or plumbing, Building Code Masters has all of the study materials available to help test takers learn how to become better educated building inspectors, plans examiners, and building officials.
