Chicago — energy & appliance code adoption
Yes — effectively. Illinois has no statewide electrical code. Chicago, as a home-rule city, runs its own Chicago Electrical Code (Title 14E, NFPA 70-2017 + amendments since March 2018) along with its own Building, Residential, and Fire Codes — entirely independent of any state baseline. Below: how Chicago differs from Illinois on appliance listing, NEC, fire code, and energy storage, with sources.
Is UL 858 required in Chicago?
