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

  1. Check if your trade requires an IDFPR state license (roofing, plumbing do)
  2. Register with your city or county for general contracting work
  3. Chicago has its own strict contractor licensing system
  4. Obtain required business licenses and insurance
  5. Complete any trade-specific exams required by your jurisdiction

Exam Requirements

Provider: Varies by trade

Cost: $75–$150

Topics covered: Illinois codes, Trade knowledge

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

Required; varies by municipality

Beyond what Illinois 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
