General Contractor licenses are not obtained at the state-level in Colorado. Instead, licensing is handled on the local level. Before a contractor begins work on a construction project, they must first check with the local codes official to determine the licensing requirements in their area. Most cities and counties in the State of Colorado require General Contractors to pass a written examination and hold a license.
Although licensing is handled at the local-level, rather than the state-level in Colorado, there are a few things that are the same across the board. Most cities in Colorado offer three different licensing classifications for General Contractors:
- Class A License- allows contractors to remodel, repair or build any type of structure or addition, including commercial and residential properties.
- Class B License- allows contractors to work on commercial buildings and single, multi-unit residences under 3 stories in height.
- Class C License- allows contractors to work on residential buildings and properties, as long as the home is not taller than 2 stories.
*Most cities also offer additional license classifications for specialized building and construction trades, such as plumbing, roofing or electrical.
In order to hold one of these license classifications, contractors are also required to take and pass a written exam, in most cities:
- Class A License Exam- 4 hours long and composed of 90 questions covering International Building Code 2006
- Class B License Exam- 4 hours long and composed of 80 questions covering International Building Code 2006
- Class C License Exam- 4 hours long composed of 80 questions covering International Residential Code 2006
Most cities also use the same company to administer the exam. In most cases, the exam is given by the International Code Council Contractor Examination Service, also known as the ICC. To find out more about contractor licensing exams, visit the ICC website at:
