How to Pass the National Standard Building Contractor “Class C Residential” ICC G13 Exam in Colorado

Are you a trade professional in Colorado looking to take the next step in your career? Whether you’re aiming to start your own firm or oversee larger residential projects, obtaining your National Standard Building Contractor “Class C” ICC G13 license is the gold standard for residential general contracting.

At Contractors of Colorado, we specialize in turning experienced tradespeople into licensed professionals. With hundreds of graduates passing their exams on the first try, our program is the proven pathway to success in the Colorado construction industry.

Why the National Standard Building Contractor “C” ICC G13 Matters

In Colorado, licensing is handled at the local municipal level. While requirements vary from Denver to Colorado Springs, many jurisdictions require a passing score on the National Standard Building Contractor “C” ICC G13 exam before you can pull permits.

This license demonstrates your mastery of the International Residential Code (IRC) and proves to building departments, and your clients, that you possess the technical knowledge to build safely and professionally.
