Colorado Contractor FAQ

General construction contractors are not regulated by the state of Colorado, but on the local level through counties, municipalities or regional regulatory jurisdictions that encompass both. Local and municipal governments usually follow the Uniform Building Code. Electrical or Plumbing contractors are regulated at the state level.

Or contact your county or local municipality

Some municipalities do require passing an examination prior to receiving a license for all or some types of building contractors. As authority to regulate differs between counties and municipalities, so too does the regulation within a county or municipality. Although there is general uniformity between jurisdictions, there are times when local communities in the same area all have different requirements for the installation or construction of a particular task. In the six-county area surrounding Denver, there are over 30 separate jurisdictions so a contractor operating in more than one community may be required to follow different building code procedures when performing the same task. You must check the building regulations and requirements for each jurisdiction you will be operating in.
