Do I need a license to work as a contractor in Colorado?

These are the questions candidates ask before they start studying.

View State Requirements

Who licenses contractors in Colorado?

Cities and counties license building and roofing contractors, and the state licenses electricians.

Building, residential, and roofing contractor licenses are issued by individual cities and counties, such as Brighton, Routt County, Jefferson County, Fort Collins, and Larimer County, and each sets its own license classes, exams, insurance, and fees. Electricians are licensed statewide by the Colorado State Electrical Board.

Jefferson County, for example, requires general, roofing, and mechanical contractors who pull permits in unincorporated areas to hold a license. Larimer County lists roofing as its own license type, and Fort Collins lists Roofing and Roofing(+) licenses.

Which exam do I take?

Most offices that test contractors name an ICC exam.

Brighton names ICC G11, G12, and G13 for ground-up construction under its Class A, B, and C general contractor licenses, and the Pikes Peak Regional Building Department lists G11, G12, G13, and G14 for its building and roofing license types. Routt County names the F-series exams, F11 through F14. Jefferson County's policy names the National Standard Roofing Contractor/Subcontractor exam for its roofing license, and Fort Collins' license table lists ICC G14 for roofing. Larimer County asks for a passing grade on the applicable ICC exam.

Some offices call for a specific code year. Fort Collins asks for the 2018 code year or newer, so check which version your office accepts before you register.

What do I need besides passing the exam?

A license application and, depending on the office, insurance and fees.

Jefferson County charges a $50 annual license fee and accepts an ICC exam passed within the last 3 years. Larimer County lists a $75 biannual fee for roofing and general liability insurance of $300,000. Routt County asks for a commercial general liability certificate with a $1,000,000 minimum. Electricians apply to the State Electrical Board after passing the state exam.

Requirements and fees change, so always confirm the current details with the city or county where you plan to work.

Can I use my license in another Colorado city or county?

Sometimes, but each office sets its own conditions.

Jefferson County waives the exam for applicants who hold a valid license from another Colorado county or municipality that required the same ICC exam. Larimer County accepts a current Colorado county or municipal license with a letter from that office.

Confirm the details with the office where you plan to work before you apply.

LICENSE TYPES & EXAM REQUIREMENTS

Find the right Colorado license path

Colorado building and roofing licenses are issued locally, and each office names its own ICC exam, while electricians are licensed by the state. Compare how several Colorado offices handle licenses, then confirm the details with the office where you plan to work.

Planning to work in more than one Colorado city or county? Jefferson County and Larimer County both accept a valid license from another Colorado jurisdiction that required the same ICC exam, which can save you from retesting. Each office sets its own conditions, so confirm before you apply.

Important: Colorado has no single contractor licensing path. Each city and county sets its own classes, exams, insurance, and fees, and passing an exam does not satisfy those other requirements. Electricians are licensed through the State Electrical Board instead.

  • G16 (Master) has 100 questions and a 5-hour limit, G17 (Journeyman) has 80 and 4 hours, and G18 (Residential) has 60 and 3 hours. All are open book and based on the 2017 NEC. Colorado licenses electricians through State Electrical Board exams given by PSI, so confirm whether an ICC electrical exam applies to you.

  • Take the version your licensing office accepts. G-series exams use the 2018 codes and F-series exams use the 2015 codes, and ICC's 2015 bulletin says the F-series will be retired on December 1, 2026. Fort Collins asks for the 2018 code year or newer.

  • Brighton, Routt County, the Pikes Peak Regional Building Department, Jefferson County, Fort Collins, and Larimer County all name an ICC exam for building or roofing licenses. Each office sets its own classes, fees, and insurance, so confirm with the city or county where you plan to work.

  • No. Passing your exam satisfies only the examination portion of licensing.

    You'll also need to apply to your city or county for the license. Jefferson County lists a $50 annual fee, and Larimer County lists a $75 biannual fee for roofing along with insurance requirements. Fees vary by office, so confirm before you apply.

  • Create an account and schedule your exam with Pearson VUE at pearsonvue.com/icc. The fee is $120 per exam, results are immediate for computer-delivered exams, and you wait 10 days before retaking a failed exam. The exams are open book, but there isn't time to look up every answer, so know your references.
