Civil Engineering across Illinois
Construction stormwater discharges are regulated by the Illinois Environmental Protection Agency through its NPDES construction general permit. Access to state highways requires permits from the Illinois Department of Transportation. In the Chicago region, the Metropolitan Water Reclamation District enforces stormwater detention and volume control requirements, and several collar counties maintain their own countywide stormwater ordinances.
Engineering in Illinois is regulated by the Illinois Department of Financial and Professional Regulation. Illinois uniquely licenses Structural Engineers separately from Professional Engineers, and SE licensure is required for the structural design of certain structures defined by statute. Firms providing professional design services must be properly registered, with licensed professionals in responsible charge.
Illinois enforces the Illinois Energy Conservation Code for commercial buildings, which is modeled on the International Energy Conservation Code. Chicago enforces its own Chicago Energy Code, which generally tracks or exceeds the state requirements. Both set minimum standards for envelope, mechanical systems, and lighting efficiency.
Chicago's Department of Buildings runs its own permitting process, including a self-certification program that allows licensed architects and structural engineers to certify code compliance on qualifying projects. Outside Chicago, permits and inspections are handled by municipal and county building departments. Illinois has no single statewide commercial plan review; authority sits with local jurisdictions.
