General Contractor Education

Colorado Contractor License Exam Preparation Classes

You’ve been doing this work long enough to be running the job instead of taking the orders.
 
Our Colorado contractor license classes meet four Saturdays a month in Lone Tree and Loveland, in person or live-streamed so you’re not giving up a workday. We prep the Class C residential exam (ICC G13) and the roofing exam (ICC G14), taught by licensed contractors who’ve passed these tests. Classes are limited to 10 to 20 students so you can ask questions and get an answer, and every session is recorded in case you miss one.

You get the exact code book edition your exam is written against, pre-tabbed and exam-approved. The Class C course covers the IRC; the roofing course includes the 2018 IBC, IRC, and IPC with a tab kit for each. Beyond the classroom, you get the portal with mock exams and quizzes that mirror the real test, plus office hours with your instructor whenever you want them. Payment plans available, and financing through Klarna or Afterpay at checkout.

Frequently Asked Questions

We know navigating licensing requirements can be overwhelming—but that’s exactly why we’re here. Our goal is to simplify the process and give you everything you need to pass with confidence.

  • Yes. All of our courses offer a payment plan: pay 50% to register and save your seat in class, with the remaining balance due during Week 3 of the course.

    We also offer financing options through Klarna and Afterpay at checkout.

    All GC and Roofing License Exam Prep programs include the cost of the code books, tab kits, & online portal. All sales are final.

Yes. We make sure you have the exact edition of the code book required for your exam.

Here’s why that matters: sometimes the licensing exams are still based on an earlier edition of the code, even though newer versions are being used out in the field. If you walk into the exam with the wrong book, it can throw you off.

Our program is designed to remove that risk. We’ll provide the correct, exam-approved code book so you can focus on studying and passing, without worrying about whether you bought the wrong edition.

We strongly recommend attending each session, since they build on the previous material and are critical to your success in the program.

That said, we understand that life happens. If a scheduling conflict arises, please notify the instructor 48 hour advance so we can help you stay on track and get the most value from the program.

Please note that enrollment is final. All sales are final, and no refunds will be issued for missed or unattended sessions, regardless of reason.

Many local code enforcement follows the 2021 or 2024 ICC code, but the path to becoming a licensed General Contractor, the ICC still runs through the 2018 IRC (Exam G13). (National Standard Building Contractor “Class C” ICC G13)

We provide you with the 2018 codebook and targeted training because that is exactly what you will see on the real exam.

Don't let the version gap worry you: the 2018 and 2021 codes are nearly identical in their structural and residential foundations. By training with us, you are preparing to pass the real exam on the first try while gaining the fundamental skills required for current building standards.

Generally, yes. But some justifications do not require it. (Sorry, we know that’s confusing, but every building department has their own requirements about documented experience before issuing a license) Reach out to the building department and confirm. 

For the Residential Contractor license, you’ll typically need at least 2 years of hands-on residential contracting experience that other general contractors will sign off on. This can include direct project management, trade work and verifiable residential contracting work history. 

For the Commercial Contractor license, the bar is higher. You’ll generally need a minimum of four years of verifiable experience on commercial job sites, specifically in a management role. In most cases, applicants are already working as superintendents or project managers for larger general contractors before they qualify to apply.

Not at this time. We only offer exam prep for the National Standard Building Contractor “Class C” ICC G13. This would be for residential general contracting work. 

ICC = International Code Council

For general contractors in Colorado (and other ICC-adopting states), the International Code Council (ICC) is the organization that writes the building codes your projects are inspected against. What that means for you:

  • Colorado adopts ICC “I-Codes” as the baseline for construction.
  • Cities and counties may amend them, but they’re still ICC-based.
  • Common codes you’ll see:
    • IRC – Residential (1–2 family homes)
    • IBC – Commercial & multifamily
    • IECC – Energy
    • IFC / IPC / IMC – Fire, Plumbing, Mechanical
  • Contractor and ICC exams are typically open-book ICC exams.

Bottom line: If you pull permits or pass inspections in Colorado, you’re working under ICC codes, whether you know it or not.

Yes, it is. The National Standard Building Contractor “Class C” (ICC G13) is a national exam, and its credentials are recognized in many jurisdictions across the United States.

Because our program is built on the International Residential Code (IRC), it is designed to prepare you for this exam regardless of which state you are in, as long as that specific area follows the ICC code and requires the G13 exam for licensure.

Important Guidelines for Out-of-State Contractors:

Confirm with Your Local Building Department: Before enrolling, you must contact the building department in the city or county where you intend to work. 

Ask specifically: "Do you require the ICC G13 (National Standard Residential Building Contractor) exam for a Class C license?" 

Don't Confuse Field Adoption with the Exam: Local jurisdictions often "adopt" older or newer versions of the code for their field inspections (e.g., they may still be inspecting based on the 2018 or 2021 code). However, you must test on the currently available G13 series as administered by the ICC. Our program focuses on the technical mastery of the code required to pass that specific exam.

Reciprocity: Many states and municipalities that don't have their own state-level test will accept the ICC National Standard results as proof of competency. This makes the G13 a highly portable and valuable credential for your career.

Bottom Line: If your local jurisdiction requires the G13 exam, this program will give you the tools to pass it. Always verify the specific exam ID with your local authorities first.

We will monitor the payment portal and follow up with you to confirm your enrollment.

For online classes, please confirm your mailing address so we can ship your code book directly to your home.  Programs run monthly, and we require at least 5-7 days between payment and the start of class to ensure your code book arrives on time. If payment is submitted the day or two before a program begins, we are unable to guarantee timely delivery of materials.

For in-person programs, please confirm your payment with our team. Your book will be here for you in our Lone Tree office for the start of class. 

As a best practice, please email [email protected] or call/text (720)475-6459 with any questions and streamlined confirmation.

Classes meet for four (4) consecutive Saturdays at our Lone Tree office. This is a classroom-only, in-person program — there is no online or hybrid option at this time. Please plan to arrive by 12:50 PM for each session. Free on-site parking is available.

Location: 9044 Forsstrom Dr, Lone Tree, CO 80124
Time: 1:00 PM – 5:00 PM

What's Included:

  • 2018 IBC, IRC & IPC Code Books with Tab Kit for each
  • Expert-led instruction from a licensed roofing professional, with a proven test-taking strategy
  • Classroom portal with progress tracking, mock exams, and quizzes
  • One-on-one office hours with the instructor, as needed

The course is led by Page Dyer, a licensed roofer bringing real, hands-on industry experience into the classroom — not just exam theory. You're learning from someone who has actually done the work.

Generally, yes, but requirements vary by jurisdiction. Every building department sets its own rules about documented experience before issuing a license. Reach out to your local building department to confirm what's required in your area.

Many jurisdictions across the country follow ICC codes and require the G14 exam for roofing licensure. Because our program is built on the 2018 IBC, IRC, and IPC codes, it's designed to prepare you for this exam regardless of which state you're in, as long as that jurisdiction follows the ICC code and requires the G14 exam.

Before enrolling, confirm with your local building department: "Do you require the ICC G14 (Roofing Contractor) exam for licensure?"

No, any organization promising a guaranteed pass isn't being honest with you. At the end of the day, you're the one sitting for the exam. That said, our program is built by an experienced, licensed roofer to give you every tool and strategy needed to walk into that testing center with confidence.

If you attend all the classes and complete the full course curriculum in your online portal, and you're unsuccessful on your first attempt at the exam, you're welcome to attend a future session with us at no additional cost. If you put in the work, we will get you across the finish line. That's our commitment.

In short: No. To be direct, any organization offering a "guaranteed pass" isn't being honest with you. At the end of the day, you are the one who has to sit for the exam and perform.

However, our track record speaks for itself. We have helped hundreds of students successfully navigate the ICC exam. We are confident that if you commit to the process and put in the work, you will have a very high likelihood of passing on your first attempt.

What it takes to succeed: This course is an intensive preparation tool, but passing requires more than just showing up. Success in this program depends on:

  • Self-Study: Consistent review of materials outside of our class sessions.
  • Discipline: Following the study frameworks we provide.
  • Engagement: Actively participating in workshops and asking questions.

Our goal is to give you every tool, tip, and strategy necessary to walk into that testing center with absolute confidence.

We strongly recommend attending each session, since they build on the previous material. If a scheduling conflict arises, please notify the instructor 48 hours in advance. Enrollment is final — no refunds are issued for missed or unattended sessions, regardless of reason.

The first step is to prepare for and pass the National Standard Residential Building Contractor “C” Exam (ICC G13), administered through Pearson VUE. Our exam prep program is designed to fully prepare you with structured instruction, in-depth textbook coverage, and realistic practice exams that mirror the actual test.

Once you complete the course, you’ll schedule and take the official exam at a Pearson VUE testing center near you.

In Colorado, general contractor licensing is handled at the local (city or county) level, not by the state. Because of this, licensing requirements vary by jurisdiction. Some building departments require multiple years of documented construction experience and letters of recommendation from licensed general contractors you’ve worked under, while others do not. Most jurisdictions will also require proof of insurance, basic business documentation, and additional application materials.

We are committed to helping students navigate licensing requirements by providing accurate information and study support. 

However, issuance of recommendation or work verification documents falls outside the scope of this course unless a formal working relationship exists. 

Students are encouraged to seek such documents from past employers who can verify their work history, aligning with licensing integrity requirements. 

Colorado does NOT have a statewide general contractor license. 

Licenses are issued by cities and counties, so details can vary slightly by jurisdiction. That said, most local governments use the same Class A / B / C framework.

Class A General Contractor - The highest level.

  • Can work on any size and type of building
  • Includes commercial, multi-family, industrial, and residential
  • Typically no height or occupancy limits
  • Does not include electrical, plumbing, or HVAC work (those require separate licenses)

Best for: Large commercial projects, high-rise, institutional, or mixed-use work.

Class B General Contractor -  Mid-level license with some limits.

  • Allows most residential and commercial construction
  • Often restricted from very large or complex structures
  • May have limits on building height or construction type
  • Specialty trades still require separate licenses

Best for: Small-to-mid commercial buildings, standard multi-family, residential developments.

Class C General Contractor - Residential-focused and limited in scope.

  • Typically limited to single-family homes and small residential buildings
  • Often capped at 3 stories and a small number of units
  • No commercial or large multi-family work allowed

Best for: Home builders, remodelers, and small residential contractors.

Nuestros cursos de preparación para el examen se imparten en inglés, ya que los exámenes de contratista del ICC se administran principalmente en inglés. Sin embargo, el International Code Council (ICC) ofrece algunos exámenes en español, dependiendo de la jurisdicción y el tipo de examen. Para verificar si el examen de Contratista Clase B (ICC G12) o Clase C (ICC G13) está disponible en español, recomendamos consultar directamente con ICC o Pearson VUE, el proveedor oficial de los exámenes. Si necesita apoyo en español, algunas jurisdicciones pueden permitir el uso de un intérprete, pero esto requiere aprobación previa.

READY TO Secure your seat?

You already know the work. You’ve framed the walls, run the crews, and watched somebody else’s name go on the permit while you handled every real decision on site. Getting licensed is what stands between that and running your own jobs, bidding your own work, and answering to nobody but the client.

Seats cap at 10 to 20 students and fill on a first-paid basis. Put down 50% to hold yours, with financing available.
