Do I need a permit for hvac replacement or installation in Mundelein?
Yes. In Illinois, hvac replacement or installation generally requires a permit, and Mundelein is no exception.
Furnace and air conditioner replacements in Mundelein are permitted as minor or standard mechanical projects, so plan on a permit even for a like-for-like swap. Confirm the current requirement with the Building Department at 847-949-3283. The installing contractor must be registered with the Village, and applications are filed through the BS&A Online portal. The Village set fees for smaller projects, with minor project permits at 50 dollars and standard project permits at 100 dollars. The Village adopts and amends the ICC codes, including the mechanical and fuel gas codes, so new equipment and any gas-line changes must meet current code. 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.
