The building

County records. A storefront outlives its tenants, which makes this the most durable thing on the page.

Building

27,728 sq ft, built 1996

Type

commercial

Observed August 15, 2026City of Naperville GIS, the same publisher as the permit feed: the building and parcel polygons containing this business's coordinates. The footage is the WHOLE structure — and this one is large enough to hold several tenants, so it is an upper bound on this business's space rather than a measure of it. Per-tenant area needs the unit, which the city does not publish
