Step-by-Step: How to Get Your Colorado Contractor License

  1. Determine if your trade requires state licensure (electrical/plumbing do)
  2. For general contracting, register with local jurisdiction
  3. Pass trade exam via PSI or ICC
  4. Obtain business license from your city/county
  5. Carry required insurance for your jurisdiction

Exam Requirements

Provider: PSI / ICC depending on trade

Cost: $85–$165

Topics covered: Trade-specific knowledge, Colorado building codes

Most state contractor exams test two main areas: Business & Law (contracts, lien law, workers' comp, licensing regulations) and Trade Knowledge (construction practices, building codes, safety). Prepare for both sections — even experienced contractors struggle with the Business & Law portion without dedicated study.

Study Resources

  • PSI Candidate Handbook (available on PSI website — free, covers exactly what's on the exam)
  • ICC Study Guides for code-based exams
  • Contractor's Business & Law Study Guide by Craftsman Book Company
  • Online prep courses from Contractor Exam Prep and similar providers

Insurance & Bonding Requirements

General Liability and Workers' Comp recommended; required by some jurisdictions

Beyond what Colorado requires, consider these coverage types for complete protection:

  • General Liability: Protects against third-party bodily injury and property damage claims
  • Workers' Compensation: Required if you have employees; protects against job-site injury claims
  • Commercial Auto: Your personal auto policy won't cover your work truck
  • Inland Marine (Tools & Equipment): Covers tool theft from job site or vehicle

Reciprocity

Colorado has the following reciprocity agreements with other states:

  • Some trades recognize NCCER certifications

Important: Reciprocity agreements change over time. Always contact the Colorado licensing board directly to confirm current reciprocity status before assuming your out-of-state license qualifies for expedited licensure.

Important Notes for Colorado

Colorado does NOT require a state general contractor license. Requirements vary significantly by municipality (Denver, Boulder, etc. have their own requirements). Electricians and plumbers need state licenses.
