Unlike their plumbing contractors, Illinois does not supervise general contractors or electrical licenses at the state level. Nearly all construction licensure will be regulated at the city or county level, with the exception of an Illinois roofing license — which will be handled through the Illinois Department of Public Health.
However, that is not to say that you do not need to be certified to perform construction work in Illinois. In most cases, your general contractor license requirements and application process will be determined by where you live, and, depending on your location, these requirements may differ. Before performing any general contracting work in Illinois, make sure to check with your local city, county, or jurisdiction.
