No Statewide General Contractor License
Idaho does not require a statewide general contractor license for most construction work. However, this doesn't mean no oversight exists:
- • Many cities and counties have their own contractor registration requirements
- • Specialty trades (electricians, plumbers, HVAC) still require state licenses
- • Always check your local building department before hiring
