Champaign County, IL Accessory Structures: Shed & Carport Rules (2026)

Section 7.2 sets yard requirements for detached accessory buildings and structures separately by district group. In the AG-1, AG-2 and Conservation-Recreation districts, Section 7.2.1 requires the front yard to follow the same setback line as the principal building under Section 5.3, and bars any detached accessory building or structure from being located less than 10 feet from a side or rear lot line. In the R-1 through R-4 residential districts, Section 7.2.2 tightens the front yard rule the same way but relaxes the minimum side and rear distance to five feet.

In business and industrial districts, Section 7.2.3 applies the Section 5.3 setback line to the front yard for accessory buildings, then caps how far a side or rear yard can be required: no detached accessory building can be required to sit more than 10 feet from a side lot line or more than 15 feet from a rear lot line, even if Section 5.3's general setback formula would otherwise demand more. Detached accessory structures enumerated in Section 4.3.3B follow a different front-yard rule in business and industrial districts.

No side or rear yard is required at all where a structure abuts a railroad siding used in the day-to-day operation of an industrial use. These are the minimum yard standards the Zoning Administrator applies when reviewing a shed or outbuilding placement as part of a Zoning Use Permit.
