Macon County, IL Home Business: Signage Rules (2026)

008's HOME OCCUPATION definition sets the sign rule directly in clause (2): there can be no display that indicates from the exterior that the building is being used for anything other than a dwelling, with one narrow exception, a single sign, not exceeding one square foot in area, that is non-illuminated and mounted flat against the wall of the principal building. 115, underscoring how tightly the county limits home-business signage compared to other residential accessory signs. The sign restriction applies together with the rest of the HOME OCCUPATION conditions, no exterior display of goods, no illumination, and it is enforced as part of the same definition that governs whether the business qualifies as a lawful home occupation at all; a sign that is illuminated, freestanding, or larger than one square foot takes the operation outside the HOME OCCUPATION definition and makes it an unpermitted use in the district.

Property owners considering a lit sign, a yard sign, or window signage advertising a home business should treat clause (2) as the entire allowance, since the code does not carve out any additional home-business sign category elsewhere in Chapter 155.
