Permit required

Yes. In Illinois, addition or structural alteration generally requires a permit, and Unincorporated Coles County is no exception.

Additions and structural alterations require a permit in essentially all Illinois jurisdictions. Illinois has no statewide residential building code for this work, so the permit threshold is set by your municipality or county. The statewide codes that took effect on 1 January 2025 apply to commercial, public and state-funded buildings. Many local codes require zoning review for lot coverage and setbacks, and properties in a mapped flood zone face additional elevation requirements.
