If you are unsure if your project requires a permit, contact the Building Division at 630-620-5750. The following items do not require a permit: Siding and Private Walks. Tree removal on private property does not require a permit, unless the area is within a Special Management Area (wetlands, flood plain, buffer zones). Then, a stormwater certification or letter of permission is required before work can begin. If you have questions, please call Private Engineering Services at 630-620-5973.

Staff does not recommend proceeding with any project without obtaining the appropriate permit. If you start a project without a permit, and the Village finds out that work is being done without a permit, the permit fees are doubled. You may be asked to take down or remove whatever work has been completed and start the project over in its entirety.
