McLean County, IL Home Business: Zoning & Home Occupation Permits (2026)

R packages that right with nine restrictions. The use must stay incidental and subordinate to the home, capped at 25% of the dwelling's total floor area (excluding the basement) and 50% of the basement if the operation spills down there. Staffing is limited to one non-resident employee actually working on site; the code does not cap employees who never visit the property. On-site retail sales are restricted to goods actually made there, though off-premises sales by phone, fax or computer are expressly allowed. The rules also bar exterior display of merchandise, outdoor storage of equipment, any exterior alteration that changes the dwelling's residential character, and any equipment that creates a nuisance from noise, vibration, smoke, dust, odor, heat, glare, emissions or electrical interference.

R(1)(k) lists occupations barred outright regardless of size, covering funeral services, grocery sales, secondhand retail, equipment rental, auto repair, medical and veterinary clinics, and adult entertainment. The Director of Building and Zoning administers permits and inspections for these standards under § 350-16.
