Observed August 21, 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
