Coverage: this report covers building permits issued by the City of Cincinnati (Buildings & Inspections Department). Other Hamilton County jurisdictions publish their permits separately and are not in this feed, so totals here are Cincinnati totals — labeled as such, never blended. Two facts about the city's data shape the counts. The dataset lists one row for every work component a permit covers, so we count each permit once and add its components' stated costs together for its value. And the dataset carries no electrical permits at all, so no electrical figures appear in this report.
