Do I need a permit for standby generator installation in Mundelein?

Permit required

Yes. In Illinois, standby generator installation generally requires a permit, and Mundelein is no exception.

Installing a standby generator in Mundelein requires a Village permit before work begins, and the electrical connection and transfer switch must be installed by a licensed electrical contractor. Apply through the BS&A Online portal. A natural-gas fuel connection is plumbing work that in Illinois must be done by a state-licensed plumber, and any contractor other than the owner must be registered with the Village. Confirm the setback, electrical, and gas requirements with the Building Department at 847-949-3283 or building@mundelein.org 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.
