Do I need a permit for hvac replacement or installation in Gurnee?
Yes. In Illinois, hvac replacement or installation generally requires a permit, and Gurnee is no exception.
Gurnee lists furnaces and air conditioners as their own permits, so replacing a furnace, AC or heat pump requires a permit under the codes the Village has adopted with local amendments. For a new AC installation Gurnee asks for a plat of survey or drawing showing where the unit will be located, plus a Village-registered electrician on file for the electrical connection. Gurnee local amendments disallow unvented gas log heaters and corrugated stainless steel tubing for fuel-gas installations, so confirm gas piping details with Gurnee Community Development. File through OneStop at onestop.gurnee.il.us. 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.
