Home / Permits / Shed / accessory structure

Do you need a permit for a shed / accessory structure?

Yes, in most cases. Sheds, detached garages and gazebos are permit items across the north suburbs, typically $50 to $200, mainly so the village can check setbacks and lot coverage before a placement inspection and a final. Some villages exempt very small sheds, and the size threshold varies, so ask before you order one.

Typical fee: $50-$200, scaled to project value in most villages.
