Do I need a permit for standby generator installation in Gurnee?
Yes. In Illinois, standby generator installation generally requires a permit, and Gurnee is no exception.
Gurnee lists generators as their own permit, so a permanently installed standby generator requires a permit for the electrical work, transfer switch and any gas line under the codes the Village has adopted. The electrician must be registered with the Gurnee Building Department, and gas work engages the Village fuel-gas amendments, which disallow corrugated stainless steel tubing for fuel-gas installations. Generator placement must meet Gurnee Zoning Ordinance setback rules. File and schedule inspections through Gurnee's OneStop online system at onestop.gurnee.il.us and confirm details with Gurnee Community Development. A permanently installed standby generator requires both electrical and often mechanical/gas permits in most Illinois jurisdictions. Many local codes enforce clearance and location rules and require a listed automatic transfer switch under the adopted National Electrical Code.
