Do I need a permit for standby generator installation in Bolingbrook?
Yes. In Illinois, standby generator installation generally requires a permit, and Bolingbrook is no exception.
Bolingbrook requires permits for new installations and alterations, so a permanently wired standby generator with a transfer switch is permitted work that must be applied for before the start of any work. The Village enforces the 2017 National Electric Code and the 2018 International Fuel Gas Code with local amendments, and all contractors must be currently registered with the Village. A natural-gas fuel connection is plumbing work that in Illinois must be performed by a state-licensed plumber. Confirm the setback and submittal details with the Bolingbrook Building Division before installation. 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.
