Study for the building inspector certification exams with 1,000 practice questions, five full-length timed mock exams, and a daily routine that keeps you coming back until exam day.
FIVE EXAMS, ONE APP
• B1 Residential Building Inspector
• B2 Commercial Building Inspector
• E1 Residential Electrical Inspector
• M1 Residential Mechanical Inspector
• P1 Residential Plumbing Inspector
B1, E1, M1 and P1 together make up the Residential Combination Inspector (R5) path, and there is a mixed R5 drill that pulls from all four.
MOCK EXAMS THAT FEEL LIKE THE REAL THING
• Real question counts and real time limits
• Drawn area by area, so a mock has the same shape as the real paper
• Flag questions and jump between them with the question grid
• No answers until you finish, just like exam day
• Leave at any time. Your paper is saved and the clock pauses until you resume
EVERY ANSWER EXPLAINED
Practice mode shows the answer straight away, with a plain-English explanation and the code section to tab to. You learn where the answer lives in the book, not only what it is.
A DAILY HABIT THAT WORKS
• One-tap daily practice sized to your goal
• Study streak and a week-at-a-glance strip
• Daily goal of 10, 20, 30 or 50 questions
• Exam-date countdown with a daily pace
• Optional reminder at the time you choose, skipped on days you have already hit your goal
MISSED QUESTIONS COME BACK
Every question you miss goes into a review queue and comes back after 1, 3, 7 and 14 days until you get it right. That is spaced repetition, the most reliable way to make an answer stick.
KNOW WHERE YOU STAND
• Score by content area after every paper

FREE AND PRO
The free plan includes lessons, calculators, the glossary, 25 questions in every content area and a 20-question taster of every mock exam. Free users can also watch a short ad to open a full mock exam or a full content area for 8 hours. Pro is one payment, not a subscription: all 1,000 questions, all five full-length mock exams, and no ads.
HONEST ABOUT THE DETAILS
Questions are written against the 2021 IRC and 2021 IBC. The weighting for B1, E1 and P1 follows the published content outlines. For M1 and B2 the weighting is our own study estimate, and the app labels it that way. Your exam reports a scaled score, so an in-app percentage is a close guide, not a prediction.
