Obtaining a Contractor's License in Colorado

Colorado is an excellent place to start your contracting business. Not only is it beautiful land, but also the state laws provide unique opportunities for new contractors. However, the requirements you need to meet before you can legally work in Colorado can be daunting. 

Colorado is unlike other states in that there is no statewide general contractor's license. Instead, municipalities administer all licenses. This local licensing means requirements for a license in your city can be different than another's. Many cities in Colorado require that you pass an ICC exam before the city processes the application for your license. 

Contractor Training Center assists anyone in need of a contractor's license. Our team of professionals understands all the material and prep you'll need for the exam and to start a successful business. With us to fall back on, there's no need to doubt your ability to obtain your Colorado contractor license as soon as possible.

Submitting a contracting license application and passing the exam are the two main steps to obtaining your license. No matter what state you're in, you can expect to need some level of preparation before you can get one. We provide the resources to help you through every step of the way, no matter the state or municipal requirements. 

We have exam prep available for all the ICC Standard General Building Contractor Exams, A, B, and C.

The Benefits of Having a Contractor's License in Colorado 

Every state will have different laws surrounding the contractor's license. Specific projects on your home or public buildings will require you to have a license. Before you begin renovations or any other building project, it's crucial to know which license you'll need in your state. 

Obtaining your license means you'll immediately have a higher earning potential for contracting jobs. This increased potential is because you can only perform smaller repair jobs without a license legally, such as grouting, caulking, and door framing. With a contractor's license, you can build things, renovate, and even earn specialty licenses for plumbing and electrician work. Clients are likely to pay more money for a licensed professional over an unlicensed handyman, letting you make more profits. 

A license in Colorado will automatically give you credibility in your municipality. The license is there to prove you have the right qualifications and experience to complete a professional job. Clients will be able to view your license and see you have put the necessary time, money, and effort into doing the job right. This credibility will make your business easier to trust and recommend to others! 

You won't be able to complete projects without a license if the project exceeds a certain financial threshold. These more significant financial projects mean more effort, profits, and community credibility. The faster you're able to pass your local license exam, the quicker you'll be able to receive a license and grow your business accordingly. The Contractor Training Center recognizes the exam is an essential step in your career, and we want to guide you through the things you'll need to succeed


Gives You Credibility

Having a license increases your credibility, allowing you to build trust with your clients. There are other ways you can gain their trust, but this is a big part of establishing yourself and your business, especially if you're working with new customers.

Getting a contractor's license isn't done overnight, and the process of obtaining a license can be considered a significant investment. Customers often feel at ease knowing a contractor has invested their own time and money working to back up their skills with a license to prove it.


Gives You a Higher Earning Potential

Consequently, there are larger projects that you can't perform without a contractor's license. With one, you can take on big assignments, get more jobs, and increase your profit. More times than not, clients will pay a higher price to a licensed contractor as opposed to unlicensed handymen.

With a license, your clients can trust that you have the knowledge and skills to do what they need. It’s an assurance that you’ll follow all applicable laws and regulations. You can build a relationship with your customers and establish trust in other ways, of course. However, a licensed contractor will stand out far more and attract customers easier.

Additionally, many states legally require businesses to hold a contractor's license to work on projects over a certain financial threshold. If you take the initiative and earn your license now, you can get more business, increase profits, and take on more significant assignments right away. Clients will typically pay a higher fee for licensed contractors because they can trust that the contractor knows what to do and how to do it well.


How to Get a Contractor's License in Colorado


Getting a Contractor's License in any Colorado Municipality is a fairly similar process. Most Colorado cities require applicants to provide proof of education and experience, list any previous licenses/certificates, obtain or supply a Tax ID number, adequate insurance, and Workers' Compensation.

Some localities also require applicants to pass a licensing exam, such as the ICC National Standard Building Contractor Exams.


Some municipalities including Denver, Jefferson County, Fort Collins, and Thornton, accept ICC National Standard Building Contractor exams.

We offer exam prep courses and materials for the following exams:

General Contractor Class A (F11 Exam): For the alteration, addition, repair, demolition, or construction of any structure or building.

Building Contractor Class B (F12 Exam): For the alteration, addition, repair, demolition, or construction on buildings and structures classified as less than a high rise by the International Building Code.

Residential Contractor Class C (F13 Exam): For the alteration, addition, repair, demolition, or construction on one- and two-family dwellings.

Getting a contractor's license in Colorado is a relatively simple process. However, you will need to research the requirements in the area where you'd like to work. As there is no statewide contractor's license in Colorado, many cities will have separate steps to obtaining your license. Use these steps as a general guide to what you should have prepared to get a contractor's license in Colorado. 

Provide Proof of Experience and Education 

As part of the initial application process for your license, you may need to provide background information. Be ready to furnish proof of your education and work experience as a handyman or contractor in another area. 

List Any Previous Licenses and Certifications 

Your municipality in Colorado may also ask for previous certifications or licenses you have already earned. If you worked as a contractor in a different city in Colorado or state, you must provide that information. 
Whether or not you have certifications in other places will not guarantee your application will get approved. You must follow through all the required steps to obtain your license. 

Check Other Prerequisites 

There are other specific prerequisites some areas may implement and not others. For example, the City of Denver requires you to have a supervisor certificate, employ a person who holds a supervisor certificate or hold a Colorado plumbing or electrical license.
Other municipalities may or may not follow Denver's lead. Therefore, you should be careful to have these types of documentation on hand as well. 

Obtain Tax ID number 

This step counts for businesses all over the United States. No matter what your company will be, you must file for an Employee Identification Number (EIN) with the federal government. 
The IRS provides your EIN for free after you fill out an application online. You should receive the number immediately afterward.

Obtain Worker's Compensation 

Colorado is unique in that all part-time and full-time workers require worker's compensation insurance to conduct business. This insurance will cover any injury that happens on the job, regardless of who is at fault. This coverage helps to prevent workers from being able to sue their employers for compensation. 

Many handypersons begin as independent contractors, so they may not have worker's compensation. It's essential to file for it and follow the correct guidelines to protect yourself and your future employees. 

Decide What Type of License Your Business Needs 

There are different contracting licenses, depending on the type of work you'd like to do. The three classes that the Contractor Training Center focuses its expertise on in Colorado include: 

  • Class A (General Contractor): For the addition, alteration, demolition, repair, or construction of any building or structure.
  • Class B (Building Contractor): For the addition, alteration, demolition, repair, or construction of any building or structure which the International Building Code classifies as less than a high rise.
  • Class C (Residential Contractor): For the addition, alteration, demolition, repair, or construction of any building of one to two-family buildings. 

Your local licensing agency will be able to tell you which licenses will require an exam. 

Apply for Your License 

After you've gathered your materials, you can submit your application. Again, where you file will depend on your municipality.

Most offices will take your application either in person, online or through the mail. Most of the time, these applications will include a fee you can write to the agency. 

No matter how long you wait, your application won't go through processing until after you pass the appropriate license exam.

Decide Which Exam to Take 
Some municipalities in Colorado accept the National Standard Building Contractor Exams validated by the ICC. These municipalities include Denver, Fort Collins, Thornton, and Jefferson County. Which one you take depends on the type of work you'd like your business to complete and where it will reside. Of course, you must also know which exam corresponds to which license you'd like to earn. 

Any of these tests will require reading and reviewing study materials. It's essential to take the test seriously for the state of Colorado to approve your license application. Order any of our valuable resources and online classes from the Contractor Training Center website to get started today.

Additional Certifications

Many cities require the ICC National Standard Builders exams for not only contractor licenses, but other certifications as well. Denver, CO requires contractor applicants to hold a supervisor certificate or state electrical/plumbing license. You can see the Denver Supervisor Certificate application and requirements here.


Preparing for the Contractors Exam 

Most people know exams from their days in school. Preparing for the contractor's exam is much the same as studying for the SAT or other standardized tests. There are many methods to absorbing the material in your way at your own pace. But no matter which way you cut it, you'll need to work on exam prep if you want to receive a passing grade! 

Contractor Training Center provides classes on exams from most Colorado municipalities. Any course you purchase will include pre-recorded lectures for you to review as much as you'd like throughout your session. Highlighting instructions and practice questions comes with the pre-recorded content as well. Students can watch, read, and review any of this material at their own pace. 

Another valuable resource we offer at the Contractor Training Center is reference manuals and texts. On our website, we sell the acceptable, official materials that you can to bring into the open book exam. We'll ship your book bundle in 1-2 business days so that you can complete your licensing application as soon as possible! 

You may use the specified books and permanent tabs on your respective exam. We provide both on our website, so you'll have them available to you. You can even purchase your book bundle pre-tabbed and pre-highlighted to save time and effort while you study. Bundles of the exam prep books are available for all of the National ICC exams required in the state of Colorado. 





You will need to register your business with the correct agency to conduct business in Colorado, depending on the nature of your company you may need to register with more than one agency.
