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

Section 7.1.1C, governing Neighborhood Home Occupations permitted as an accessory use in any zoning district, allows "no SIGN other than a name plate not more than two square feet in area." That is the entire signage allowance: no lit signs, no freestanding advertising, nothing beyond a small identifying plate, and the rest of Section 7.1.1 separately bars any exterior modification or display that would signal the property is being used for anything other than a residential dwelling. Rural Home Occupations, the separate track under Section 7.1.2 for accessory businesses on AG-1, AG-2 and CR-zoned lots that do not front a subdivision street or sit within 500 feet of a residential district, get a slightly larger allowance: Section 7.1.2D permits "no more than one SIGN, not more than six square feet in area." Both figures are hard caps with no discretionary path to a larger sign built into these sections; a home business wanting bigger signage would need to seek Special Use Permit relief under Section 7.1.1L, which is available only if the underlying use is not on the prohibited-activities list in Section 7.1.1I.

Both home occupation types must also register with the Department of Planning and Zoning before operating, and the sign limits apply regardless of whether the business itself is otherwise conforming.
