ICC Commercial B2 study guide
ICC Commercial B2 · Work through your exam, one topic at a time.
The ICC Commercial Building Inspector (B2) credential is one of the certification opportunities the International Code Council describes as supporting career development for building safety professionals. ICC Credentialing states that its credentials "demonstrate a confirmed commitment to protect public health, safety, and welfare," and positions certification as a way to raise the professionalism of a department while furthering an individual's career. The B2 designation is aimed at inspectors who review and inspect commercial buildings for compliance with the commercial provisions of the International Building Code. Candidates are typically code enforcement officers, plans examiners moving into field inspection, or trades professionals transitioning into building safety. The ICC Commercial B2 study guide has 5 sections and about 1,729 words.
