Business Occupancy — A building shall not be constructed or occupied, an existing building shall not be expanded or otherwise altered or occupied, a new land use shall not be established and an existing land use shall not be changed until a certificate of occupancy is issued by the Department of Building and Zoning. Every certificate of occupancy shall state that the land use and occupancy of buildings or structures comply with all provisions of the Cook County Zoning Ordinance and that buildings or structures are habitable and in conformance with all applicable building regulations. [...] Home Based Business Occupancy — Home occupation is defined by the Zoning Ordinance as: An occupation or profession, practiced by a member of the family residing on the premises, and which occupation is clearly incidental and secondary to the residential use of the dwelling.
Full Breakdown
The Cook County Zoning Ordinance requires that home occupations remain incidental and secondary to the residential use of the dwelling. This means the business must not generate customer traffic or parking demands that exceed what is normal for a residential neighborhood. The zoning administrator reviews home occupation affidavits for compliance. Businesses that attract significant foot traffic, require employee parking, or generate delivery vehicle activity may not qualify as home occupations. The Department of Building and Zoning investigates complaints about home business traffic in unincorporated areas. Businesses that outgrow home occupation parameters must relocate to an appropriately zoned commercial location.
Violations & Fines
Excessive traffic from home business: zoning violation, $100–$1,000 fine. Business may be ordered to cease if residential character is altered.
