How Schaumburg Handles Accessory Structures: A Practical Guide

Schaumburg maintains 144 local ordinances across all categories, and 2 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where Schaumburg falls on the strict-to-permissive spectrum compared to other cities.

Shed & Carport Rules

Schaumburg caps portable sheds at 25 square feet with no permit needed, fixed sheds in a side yard at 100 square feet and 9 feet tall, and any other detached accessory building at 200 square feet or 40 percent of the rear yard, whichever is less, under § 154.63(E).

Key details: Portable shed max: 25 sq ft, no permit required. Fixed shed (rear yard) max: 200 sq ft or 40% of rear yard. Fixed shed (side yard) max: 100 sq ft, 9 ft height. Detached garage max: 600 sq ft or 40% of rear yard. Setback from lot lines: 5 feet minimum.

An oversized or misplaced shed or accessory structure is a zoning violation enforced under § 10.99, the Code's general penalty, which carries a fine of $100 to $50,000 with each day the violation continues counted as a separate offense. Because portable sheds over 25 square feet and any fixed shed or detached garage require a building permit, erecting one without a permit can also trigger a stop-work order and removal requirement from the community development department.

Tiny Homes

Schaumburg does not recognize tiny houses, accessory dwelling units, or intermodal shipping containers as a lawful construction or occupancy type. Village Code § 153.14 strips the 2021 IRC's tiny-house provision, section R301.1.4, out of the adopted code entirely, along with the code's tiny-house appendix.

Key details: Tiny houses: Not a permitted construction or occupancy type. ADUs: Also excluded from the adopted code. Shipping containers: Also excluded from the adopted code. Deleted provision: 2021 IRC § R301.1.4 and Appendix AQ. Adopting ordinance: Ord. 22-084, passed Oct. 25, 2022.

Attempting to construct or occupy one of the banned building types without an adopted code basis leaves an applicant unable to secure a building permit at all under § 153.03.4, since the community development department has no adopted standard to approve against. Any structure built without an accompanying valid permit is subject to the general penalty in § 10.99 through § 153.99, and the village attorney may sue to compel removal of an unlawfully constructed or occupied structure.

Compared to other cities, Schaumburg takes a harder line on tiny homes. The enforcement and penalty structure reflects that.

The Bottom Line

Schaumburg's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Schaumburg is broadly strict or permissive.

Keep in mind that Schaumburg can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
