Do I need a permit for electrical panel or service upgrade in Unincorporated Cook County?
Yes. In Illinois, electrical panel or service upgrade generally requires a permit, and Unincorporated Cook County is no exception.
Replacing or upgrading an electrical service panel requires an electrical permit in essentially all Illinois jurisdictions and must meet the adopted National Electrical Code. Most local codes require utility disconnect coordination and grounding/bonding upgrades to current code. In Cook County, permits outside the cities are handled by the Cook County Department of Building and Zoning, reachable on 312-603-0500 at https://www.cookcountyil.gov/agency/building-and-zoning. Its online permit portal is https://bzpermits.cookcountyil.gov/permit-status/. This office permits the unincorporated parts of Cook County. If your address sits inside a municipality, that municipality issues the permit instead. A service change needs the inspection to clear before the utility resets the meter, so schedule it before the changeover day.
