In Illinois, there is no single statewide rule for a Driveway Paving; whether you need a permit is decided locally in Cook County.
An at-grade driveway on private property usually needs no building permit (IRC R105.2 exempts driveways under 30 inches above grade), but creating or modifying the curb cut (the driveway approach where it meets the street) almost always requires a right-of-way or encroachment permit from the city's public works department. A new driveway, or widening one, typically needs a permit for impervious-surface and drainage review (many cities cap impervious coverage at 40-60% of the lot), while resurfacing or replacing in the same footprint is usually exempt. Because Illinois leaves this to local jurisdictions, the reliable answer comes from City of Chicago Department of Buildings. Zoning setbacks apply either way.
