Summary
Naperville allows accessory home occupations in any dwelling that meets strict standards: a live-in employee, no outdoor operations, and a 25 percent floor-area cap on business space.
A home occupation is an accessory use so located and conducted that the average neighbor would not be aware of its existence except for a sign... At least one employee of the home occupation shall reside at the residence where the home occupation is located... The home occupation shall be subordinate and incidental to the principal use of the building or structure for residential purposes and shall not exceed twenty-five percent (25%) of the gross floor area of the dwelling unit and accessory buildings or structures on the premises.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 101).
Full Breakdown
Under § 6-2-8, Naperville permits home occupations, professional offices, tutoring, dressmaking, and similar in-home businesses, in any dwelling unit or accessory building where dwellings are allowed, provided the business stays invisible to neighbors except for a sign. At least one employee must live at the residence, and the space used cannot exceed 25 percent of the dwelling's gross floor area. Outdoor storage, outdoor assembly, and outdoor business activity are all barred, and daily business trips are capped at 125 percent of a typical residential trip count. Retail sales, eating establishments, veterinary offices, and several other uses are flatly prohibited regardless of these standards.
Violations & Fines
Exceeding the floor-area cap, running prohibited uses like retail or veterinary care from home, or generating outdoor activity violates § 6-2-8 and draws the Code's general penalty of $100 to $500 per day under § 1-4-1.
