About ICC B1, B2 & F3 Exam Prep
Kalyta is an AI-native study companion for three ICC certification exams: B1 Residential Building Inspector, B2 Commercial Building Inspector and F3 Fire Plans Examiner. It adapts to what you keep missing, explains every answer, and because these exams are open book, it shows where each provision lives in your own edition of the code.
THE EXAMS
All three are ICC National Certification exams: multiple choice with four options each, sat open book with the code book and a calculator on screen, and offered against both the 2021 and the 2024 code editions.
- B1 Residential Building Inspector: 60 questions in 120 minutes, against the International Residential Code (IRC).
- B2 Commercial Building Inspector: 80 questions in 210 minutes, against the International Building Code (IBC).
- F3 Fire Plans Examiner: 60 questions in 210 minutes, against the International Fire Code (IFC), with the parts of the IBC its outline covers.
BUILT FOR AN OPEN-BOOK EXAM
Open book means these exams are not really memory tests. They are search tests, under the clock. After you answer, Kalyta shows where that rule sits in your edition of the code: the chapter and its title, every parent heading above it, and the part of the section the provision is in, and on the F3, which book it is in. You practice the lookup, not just the answer.
CHOOSE YOUR CODE EDITION
You sit the exam against one edition, and a rule often stays put while its section number moves. Pick 2021 or 2024, and the questions, lessons and lookups are all served for that book.
EVERY CONTENT AREA
Every content area of ICC's published outline for each exam is covered, in both code editions: practice questions with worked explanations, concept lessons, and a section lookup on every question.
WHAT YOU GET
- Adaptive practice: questions are chosen around your current level and mixed with spaced review, so your time goes where it moves your result.
- A worked explanation on every question: why the right answer is right, and why each of the others is wrong.
- A section lookup after every answer, pointing into the edition you chose.
- Concept lessons: short, focused reading on the rule behind the question.
- An AI tutor you can steer: ask why an answer works, ask for another example, or tell it to slow down.
- Timed rehearsals in each exam's format, drawn across its content areas and reported as the number you answered correctly.
- Review and progress: revisit a rehearsal question by question, watch your accuracy trend, and see which content areas are weak.
HONEST BY DESIGN
ICC reports these exams as a scale score, not a percentage, so Kalyta does not predict your result or your chance of passing. We publish no pass rates, score improvements or testimonials. Kalyta is study material, so it stays outside the exam room: ICC permits bound code books and approved references, not study guides or practice questions.
Kalyta is an independent study tool, not endorsed by or affiliated with the International Code Council. ICC, International Residential Code, IRC, International Building Code, IBC, International Fire Code and IFC are trademarks of the International Code Council, Inc. Kalyta does not reproduce the code and is not a substitute for the code books themselves.
HOW THE FREE ACCESS WORKS
Your first seven study days are free. No card, no payment details and nothing to cancel: a study day counts only on a day you answer a question. This is free access to the app, not a trial attached to the subscription below.
