🛁 Bathroom Remodel permit in Illinois

Renovating a bathroom — fixtures, tiling, ventilation, and sometimes relocating plumbing. Here is the Illinois-specific rule: who issues it, typical fees, timeline, go / no-go, and the official source to verify.

Verify locally. Illinois has no single statewide building code — most municipalities adopt the IRC locally while Chicago enforces its own 2019 Chicago Building Code. Permit rules differ significantly between Chicago and the rest of the state; verify with your specific city (e.g., Chicago DOB or Springfield). Rules below are Illinois-level guidance drawn from official sources — always confirm with the issuing building department before starting work. See the county permit authorities to find the right office.
