Garage - Attached and Detached Resource Guide

When constructing an attached or detached garage, a permit is required.  If you have hired a contractor(s) to perform the work, they must obtain a Contractor's Business License with the Village before a permit can be issued.

Prior to the installation of your detached garage, a string line should be run between the corner markers of your property. This accurately indicates the boundary line between properties.   Your detached garage should be installed relative to the string line according to the guidelines set forth in the Definitions section below. Leave the string line in place to be inspected with the final inspection for the detached garage.

Questions can be directed to the Permitting Division of the Community Development Department at 847.923.4420.
