Do I need a permit for hvac replacement or installation in Bolingbrook?
Yes. In Illinois, hvac replacement or installation generally requires a permit, and Bolingbrook is no exception.
Bolingbrook requires permits for renovations, alterations, and repairs, and the Village fee schedule lists a residential HVAC permit, so replacing a furnace or air conditioner is permitted work that must be applied for before the start of any work. The Village enforces the 2018 International Mechanical Code and 2018 International Fuel Gas Code with local amendments, so new equipment must meet current code. All contractors must be currently registered with the Village. Confirm the exact submittal for your replacement with the Bolingbrook Building Division before scheduling installation. 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.
