ExploreAbout this exam
ICC 77 refers to the Certified Building Official (CBO) credential offered by the International Code Council (ICC). The CBO is an ICC professional certification for individuals who manage or perform building department functions - typically building officials, plans examiners, inspectors, and code enforcement staff who want to demonstrate competence at the departmental leadership level. ICC describes its credentialing program as a way for building safety professionals to "Advance Your Career with ICC Certification," and its codes, standards, and building safety solutions are used to ensure safe, affordable, and sustainable communities and buildings worldwide. The exam is intended to test whether a candidate can apply code knowledge in the administrative and technical decisions a building official makes. Preparation generally means studying the applicable International Codes and the administrative provisions governing code enforcement, plus ICC's own training options - ICC lists training programs, ICC Learn Live events, and an Online Learning Subscription among its professional development offerings, and an Exam Catalog is published for candidates choosing a certification. Because the ICC certification page for the Certified Building Official returned a "Page not found" error when checked, specific exam details (question count, time limit, passing score, fee, retake policy, and validity period) are not confirmed here. Candidates should verify current specifics directly with ICC before scheduling.
What you'll study
About ICC 77 preparation
Is this the official ICC Certified Building Official page?
No. This is an independent study resource and is not affiliated with or endorsed by the International Code Council. It is written to help you find your way around the CBO credential. Always treat ICC's own materials as the authoritative source for requirements, fees, and scheduling.
How many questions are on the ICC 77 exam and how long is it?
We could not confirm this. The ICC page for the Certified Building Official returned a "Page not found" error when checked, so question count and time limit are unverified here. Check the ICC Exam Catalog, which ICC publishes for candidates selecting a certification, before you build a timed practice plan.
What score do I need to pass, and what does the exam cost?
Those figures are not confirmed in our source material, so we do not state them. Passing scores and fees change and are set by ICC. Confirm both through ICC's credentialing pages or your testing provider before you register, and budget for a possible retake.
If I fail, how soon can I retake the exam?
ICC's retake policy is not confirmed here. Retake rules typically specify a waiting period and a new fee, and sometimes a limit on attempts within a window. Ask ICC support or check the credentialing pages for the current policy before assuming you can retest immediately.
How long is the certification valid, and how do I renew it?
Not confirmed in our source. ICC maintains a "Maintain/Renew Certification" section within its credentialing pages, which is where renewal requirements and continuing education expectations are published. Check that page for the current validity period rather than relying on secondhand summaries.
Who should sit for the Certified Building Official exam?
It suits people already working in code enforcement who carry or are moving into departmental responsibility - building officials, senior plans examiners, supervisors, and inspectors preparing for advancement. It is a leadership-level credential, so practical experience applying the codes to real projects matters as much as memorizing text.
What should I study first?
Start with the administrative provisions that govern how a building department operates, since the official role is largely about administration, interpretations, and enforcement decisions. Then work through the technical codes you enforce locally. Confirm which code editions your jurisdiction has adopted, because editions differ and exam content follows the edition ICC specifies.
Where can I find ICC training and preparation options?
ICC lists several professional development routes: Training Programs, ICC Learn Live events, an Online Learning Subscription, and a Preferred Provider network. Its Exam Catalog is the place to identify the specific exam. Review those listings for current offerings rather than relying on older course names you may have seen elsewhere.
What trips people up most on this kind of exam?
Two things: studying technical code sections without the administrative framework the official is tested on, and practicing without a timer. Also common is preparing against the wrong code edition. Confirm the edition ICC tests, then practice applying sections to scenario-style questions instead of only rereading text.
Can I check whether someone is actually certified?
Yes. ICC provides a "Search for Certified Professionals" tool within its credentialing pages. That is the reliable way to verify a certification, including your own once you pass, rather than relying on a certificate image or a résumé claim.
