ICC National Certification Programs
ICC National Certification programs cover a wide range of professional roles, including residential and commercial building inspection, electrical, plumbing, and mechanical systems, as well as plans examination. These certifications are based on the International Codes (I-Codes), which form the foundation of construction regulation across the United States and many international jurisdictions. Candidates can choose from single-discipline certifications or pursue broader credentials that validate expertise across multiple trades.
