What work requires a permit? What happens if I don't obtain a permit?

Any work that requires a structural change such as any types of additions; alterations involving moving or adding walls; all electrical & plumbing work; all fire suppression & detection work; all HVAC work; fences, decks, roofs, driveways, patios, retaining walls; parking lots; pools; hot tubs; spas; or exterior wall mounted signs. 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.
