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

Exam Requirements
Provider: PSI / ICC
Cost: $65–$120
Topics covered: Idaho 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 per trade
Beyond what Idaho 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
Idaho has the following reciprocity agreements with other states:
No active reciprocity agreements.
Important: Reciprocity agreements change over time. Always contact the Idaho licensing board directly to confirm current reciprocity status before assuming your out-of-state license qualifies for expedited licensure.
Important Notes for Idaho
Idaho has no state general contractor license — work directly with local permit offices. Electrical, plumbing, and HVAC trades do require state licensure.
