Idaho Contractor & Trade License Requirements

Idaho uses a split system: specialty trades (electrical, plumbing, HVAC) are licensed statewide through the Division of Occupational and Professional Licenses (DOPL), while general contractors and roofing contractors only need to register with the Idaho Contractors Board (no exam required). Registration applies to any construction work exceeding $2,000 in materials and labor. As of 2025-2026, Idaho is transitioning from annual to biennial registration cycles.
