Many projects, from new commercial buildings to small residential improvements, require a building permit. However, there are many types of home improvements that do not requirement a permit such as replacing kitchen cabinets and counters, installing new carpeting or other flooring, or repairing minor damage. If you have questions about whether your project requires a permit or not, please contact Building at 815-356-3605.
The permit process involves three main steps: application, plan review, and inspection. Building staff will work with you at each stage of the project to ensure the successful completion of your project. The permit process ensures projects are constructed safely. Plan reviews and field inspections allow Building to verify that each project meets the minimum requirements of the adopted building codes and City Ordinances.
