Illinois does not have a state-level license requirement for general contractors. However, most municipalities within Illinois do have their own licensing or registration requirements for general contractors.
A City of Chicago general contractor license is required to perform most types of building construction, alteration, repair, and demolition work within the City of Chicago.
Ing to general guidelines, easy permits can be obtained the same day through the City. However, it's best to budget around four weeks for the reception of a building permit if you're applying through the easy permit system.
