Do I need a permit for kitchen remodel in Unincorporated Cook County?

Permit may be required

It depends. Whether kitchen remodel needs a permit in Unincorporated Cook County comes down to the details of your project.

Illinois has no statewide list of work exempt from a residential permit, so your municipality or county decides whether cabinets and countertops alone need one. New circuits, moved plumbing or gas, and wall changes are the usual triggers. Moving a sink or adding a water or drain line is plumbing under the statewide Illinois Plumbing Code and must be done by a licensed plumber, unless the owner-occupant exemption in 225 ILCS 320/3(2) applies. If the remodel opens walls, the Energy Efficient Building Act requires exposed exterior wall, ceiling or floor cavities to be filled with insulation (20 ILCS 3125/20(c)). This remodel moves walls, plumbing or gas lines, or adds electrical circuits. Replacing cabinets, counters and appliances in place is the part of a kitchen remodel most often exempt; layout and trade work are not. Each trade normally needs its own permit and rough-in inspection before walls are closed, and removing a load bearing wall usually needs a beam detail or engineering. Gas line changes are work many places restrict to licensed gas fitters or plumbers, and a pressure test is commonly part of the inspection.
