Contractor License in Illinois (IL) — Complete 2026 Guide
Illinois does not require a statewide contractor license for general contractors. However, this doesn't mean you can work without any licensing at all.
Many cities and counties in Illinois have their own licensing requirements. Additionally, specialty trades (electrical, plumbing, HVAC) typically require state-level licenses even when general contracting doesn't.
