Full Breakdown

The Aurora Code of Ordinances adopts the 2024 International Plumbing Code as 'the Plumbing Code of the City of Aurora' and requires anyone installing, altering, repairing, or replacing a plumbing system to first apply to the building official and obtain a permit, per the city's Building Code amendments. Work must be performed by a City of Aurora-registered plumbing contractor licensed by the State of Illinois or City of Chicago, unless the owner personally occupies and works on their own single-family home. The rule applies citywide, whether the address sits in Kane, DuPage, Will, or Kendall County, since Aurora is a home rule city under Illinois law.

Violations & Fines

Plumbing work performed without a permit or by an unregistered contractor violates the code; penalties follow the adopted International Building Code's violation and unlawful-continuance fine schedule.

Frequently Asked Questions

Do I need a permit to replace a water heater in Aurora?
Not for a like-for-like replacement of the same type, capacity, and fuel demand, which is specifically exempted from the plumbing permit requirement.
Can I do my own plumbing work in Aurora?
Only if you own and occupy the single-family home and don't hire outside help; otherwise the work must be done by a City-registered plumbing contractor.
