Do I need a permit for shed or accessory structure in Schaumburg?

Yes. In Illinois, shed or accessory structure generally requires a permit, and Schaumburg is no exception.

Illinois has no single statewide shed threshold, so the 200 square foot figure quoted from the model International Residential Code does not govern here. Requirements are set by each municipality, and the ones we have checked are stricter than that figure: Wheaton does not require a building permit for a shed of 120 square feet or less, and Joliet requires a shed permit with a Residential Accessory Structures Review Form and a plat of survey showing the shed location. Assume the local number rather than a national one, and ask your building department for the threshold that applies at your address before you buy the shed. Zoning setbacks, easements and lot coverage still apply where no building permit is needed, and running electrical or plumbing to the shed triggers its own permit. Schaumburg requires a permit to construct a shed. Under the Village Shed Resource Guide, a rear-yard shed can be up to 200 square feet and 15 feet tall, must sit at least 5 feet from all property lines, and at least 2 feet from the principal structure or any other accessory building. Sheds and other accessory structures must meet the Village's zoning setback rules, and the plat of survey must show the exact proposed location. Applications are filed through the OpenGov permit portal. Any contractor performing the work must hold a Village Contractor's Business License before the permit is issued. Confirm the current size and setback limits with the Community Development Department at 847-923-4420 before you build.
