Colorado does not require contractors to be licensed at the state level, but some local jurisdictions do. In some cases, purchasing a contractor license bond is a prerequisite for licensure.
Additionally, Colorado’s Little Miller Act requires contractors working on certain state-funded projects to purchase both performance bonds and payment bonds. Many private project owners also require them. Bid bonds may be required when contractors are selected through competitive bidding. These are the most commonly required Colorado construction bonds, but both government contracting authorities and private project owners may require a contractor to furnish any of the following:
- Maintenance bonds
- Subdivision/site improvement bonds
- Supply bonds
- Solar decommissioning bonds
- Right of Way bonds
