Naperville's Home Business: The Rules That Matter

Every city handles home business a little differently. In Naperville, Illinois, there are 6 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Key details: Standard: Undetectable by neighbors. Traffic: Must match residential. Deliveries: Cannot be excessive. Code: Title 6 Zoning.

Zoning Restrictions

Naperville allows home occupations as accessory uses in residential zones under Title 6 zoning regulations. The business must not exceed 25% of the dwelling's gross floor area and must be undetectable by the average neighbor except for a permitted sign.

Key details: Max Floor Area: 25% of dwelling. Visibility: Must be undetectable. Daycare Exempt: 7 or fewer individuals. Code: Title 6 Zoning.
