Des Plaines, IL Home Business: Zoning Restrictions (2026)

The Des Plaines Zoning Ordinance allows home occupations as accessory uses in R-1 single-family, R-2, R-3, and R-4 residential districts. The home occupation must be conducted entirely within the principal dwelling and clearly subordinate to its residential use. Only members of the immediate family residing on the premises may engage in the business. No more than a limited percentage of the dwelling's floor area may be devoted to the business. No noise, vibration, smoke, dust, odor, glare, or electrical interference beyond normal residential levels is permitted. No exterior evidence of the home occupation, including signs, outdoor storage, or display, may be visible. Only articles produced or assembled on the premises by the occupant may be sold, and retail sales generally must occur off-site. Prohibited home occupations typically include auto repair, beauty shops with multiple stations, kennels, restaurants, and medical or dental offices with multiple patient visits. Des Plaines's Department of Community and Economic Development administers home occupation compliance. Many home occupations require an annual home occupation registration with the City.
