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.

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.

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. 

The GC License Exam Prep Class is a highly focused, exam-driven program designed specifically to help you pass the ICC General Contractor exam. It teaches proven test-taking strategies, code navigation, and exam-specific concepts so you can confidently earn the credential required to pursue licensure.

The GC101 Program, offered by Contractors of Colorado, is a 4-week intensive designed to help you skip the learning curve and step into the role of a high-value General Contractor.

This is not a passive lecture series. GC101 is a hands-on, practical workshop built for experienced tradespeople who are ready to transition from working for a paycheck to running a professional general contracting business. In short:

• Exam Prep helped gets you licensed
• GC101 teaches you how to operate, protect, and grow a real general contracting business

GC101 is a 4-week, intensive program designed to help trade professionals transition from "working for a paycheck" to running a high-value, professional general contracting operation.

Instead of learning through expensive trial-and-error, such as underquoted jobs and client disputes, GC101 provides a practical "blueprint" for business success. Led by Matthew Pennington, a veteran contractor and inspector with over 20 years of experience, the program consists of 16 hours of in-person training focused on five essential pillars:

• Client Relations & Professional Presence: Master the intake process to win the right jobs.
• Defensible Estimating: Build bids that protect your profit margins and prevent "scope creep."
• Blueprint Reading & Permitting: Navigate technical plans and building departments with confidence.
• Risk Management: Understand insurance and liability to protect your business before issues arise.
• Growth Marketing: Build a digital marketing engine that consistently generates leads.

GC101 is not a passive lecture; it is a high-impact workshop designed to strip away the fluff and give you the hard-earned business intelligence needed to build a sustainable, profitable career.

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.
