Do I need a permit for standby generator installation in Highland Park?
Yes. In Illinois, standby generator installation generally requires a permit, and Highland Park is no exception.
Highland Park requires a permit for a standby or emergency generator and publishes an Emergency Generator requirement sheet. Apply through the Civic Access portal before installation. Confirm the current submittal checklist with the Highland Park Building Division. The transfer switch and wiring must be installed by a State of Illinois licensed electrical contractor registered with the City, and the natural-gas fuel connection is plumbing work that requires an Illinois state-licensed plumber. Generator placement must meet Chapter 150 zoning setbacks and noise limits, and lots near ravines or bluffs may face additional siting review. Verify placement before you order the unit. 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.
