Source: City of Naperville building permits (the current permit system plus the city's older records). The window is October 2023 through September 2026; a permit filed after that isn't here yet.
A filed value is what the contractor wrote on the permit when they applied. It is not a quote and not the final bill.
Counts are permits, not jobs: one job can need several permits, and one permit can cover several visits.
