What Illinois Actually Regulates
The state licenses fewer trades than most people assume, and garage door work is not one of them.
Illinois has no state-level general contractor licence. The state regulates roofing and plumbing specifically, and electrical work is handled through local jurisdictions. Garage door installation and repair is not among the trades the state regulates, which means the meaningful checks are local: registration with the municipality where the work happens, and whatever that city requires to pull a permit. Because there is no state credential, anyone in Illinois can describe themselves as a garage door contractor, so the local question is the one with a checkable answer.
