The key difference between the National Standard Building Contractor "B" (ICC G12) and the National Standard Residential Building Contractor "C" (ICC G13) lies in the scope of work each license allows:

Class B (ICC G12) – Building Contractor Allows contractors to construct, remodel, or repair commercial buildings up to three stories as well as residential structures. Exam covers the 2018 International Building Code (IBC), 2018 International Residential Code (IRC), and Concrete Manual.

Class C (ICC G13) – Residential Contractor Limited to one- and two-family dwellings and townhouses up to three stories. Exam focuses solely on the 2018 International Residential Code (IRC). In short, Class B contractors can work on both commercial and residential projects, while Class C contractors are restricted to residential projects only

The Class C course is $2,500 and the Class B course is $3,000. Both include everything you need to pass, including your text books you will tab and highlight to easily reference code during the exam.

Since the Class B exam is more extensive, this course follows a 6-week, small-class format to ensure personalized instruction. Enrollment is offered on a rotating basis, allowing students to join as space becomes available.

The Class C course is in-person, with 16 hours of instruction spread across four Saturdays, plus online office hours available Tuesday through Friday from 6 PM to 8 PM for additional support.

Our next course dates are June 7, 14, 21 and 28th with class starting at 8am and ending at 12pm.

The Class B course follows a 6-week, small-class format with a rotating schedule. While primarily in-person, it may include virtual components for added flexibility.
