Full Breakdown

Data centers aren't a permitted-by-right use anywhere in Naperville's zoning code. The ORI district is the only district that lists them at all, and only as a conditional use: a developer must file a conditional use petition under Section 6-3-8 and Chapter 4, go through the Plan Commission and City Council public hearing process, and satisfy required conditions on traffic, site access, building design, landscaping, and screening before the City will approve one. Outside the ORI district, a data center has no zoning path in Naperville.

Violations & Fines

Building or operating a data center outside the ORI district, or without an approved conditional use permit, is a zoning code violation enforceable by the Zoning Administrator, subject to stop-work orders and the Title's general penalty provisions.
