Do I need a permit for bathroom remodel in Carol Stream?

Permit may be required

It depends. Whether bathroom remodel needs a permit in Carol Stream 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.
