Do I need a permit for bathroom remodel in Joliet?

Permit may be required

It depends. Whether bathroom remodel needs a permit in Joliet comes down to the details of your project.

The Illinois Plumbing Code applies statewide, including to homes, and all plumbing must be done by an Illinois licensed plumber (225 ILCS 320/3). An owner or lessee who lives in a single family residence as a sole and exclusive residence may do their own plumbing, but it must meet the Illinois State Plumbing Code, is subject to inspection, and the owner may not hire anyone other than a licensed plumber to help. Whether a building or electrical permit is needed for the rest of the work is set by your municipality or county, because Illinois has no statewide residential code for existing homes. This remodel moves plumbing, adds a tub or shower, or changes wiring, exhaust venting or walls. Like-for-like fixture swaps are the part of a bathroom remodel most often exempt; moving pipes and new wiring are not. Plumbing and electrical work each normally need their own permit and rough-in inspection before the walls are closed, so schedule inspections before drywall or tile backer goes up. Bathrooms have specific electrical safety rules, such as ground-fault protection on outlets, which the electrical inspection checks.
