What is the Chicago Building Code 2022 modernization?
Answered by AskBaily Editorial · Updated
Short answer
Chicago ran its own 1949 municipal code until 2019, when the city adopted an International Building Code-aligned framework phased through 2022-2026. Energy, mechanical, structural, and accessibility chapters changed materially. Any project filed under a 1949-era scope must be re-engineered to the current code — verify with your BACP-registered GC before relying on old drawings.
