Do I need a permit for hvac replacement or installation in Highland Park?

Permit likely required

Most likely yes. Hvac replacement or installation usually requires a permit in Illinois. Confirm the specifics with Highland Park.

Highland Park requires permits for mechanical work under the 2024 International Mechanical Code and 2024 International Fuel Gas Code. Replacing a furnace, air conditioner, or heat pump generally needs a permit, so confirm whether your specific like-for-like swap qualifies with the Highland Park Building Division before scheduling install. Gas piping changes must be done by an Illinois state-licensed plumber and electrical connections by a state-licensed electrical contractor registered with the City. New equipment must meet the current adopted codes and the 2024 Illinois Energy Conservation Code even when it replaces an older unit. Most Illinois jurisdictions require a mechanical permit to replace a furnace, air conditioner or heat pump, even for a like-for-like changeout. Gas piping, venting and any new electrical circuit normally require their own trade permit, inspection and pressure test. Which code edition applies is set by your municipality or county, because Illinois has no statewide residential building code for work on an existing home.
