Chicago permit leads: the project, what it’s worth, and who’s building it
Every week, Chicago publishes the building permits it just issued — with the project address, the reported job cost, and the contractors on the job. I pull the commercial ones and send you the spreadsheet.
The limits, up front. The city publishes no phone numbers, emails, or ZIP codes on permits. The reported cost is the applicant’s own figure, missing on about a quarter of rows. Blank stays blank — I don’t fill gaps with guesses. And Chicago publishes no commercial/residential flag, so I classify each permit from the city’s own work description (a commercial use named, a mixed-use project, or a multifamily building of 3+ units). Permits whose descriptions don’t say what the building is get excluded, not guessed at.
