Do you need a permit?
Cook County requires a permit for electrical work.
Cook County's Department of Building and Zoning permits only unincorporated Cook County and the Forest Preserves of Cook County - its own page states the department 'oversees all building and zoning matters in the unincorporated areas of Cook County and all of the Forest Preserves of Cook County' and directs anyone inside a municipality to their local building and zoning authority. Cook County runs a full electrical permit program with its own fee schedule, plan review and inspections in the unincorporated area, and electrical approval is one of the sign-offs required before any permit placard is issued. Contractors must be registered with the county.
