What is in the file1,000 rows pulled 25 Aug 2026
The file would be ONE of the five slices below, not all 1,000 rows. Chicago publishes a building-permit table and overwrites it. We pulled 1,000 of those rows on 25 Aug 2026 and assembled them as one CSV, with person-name columns taken out. The five slices described here are Easy Permit Process, Express Permit Program, Signs, Renovation / alteration, New construction.

Required notice from the City of Chicago, printed here at the point of sale, character for character:
This site provides applications using data that has been modified for use from its original source, www.cityofchicago.org, the official website of the City of Chicago. The City of Chicago makes no claims as to the content, accuracy, timeliness, or completeness of any of the data provided at this site. The data provided at this site is subject to change at any time. It is understood that the data provided at this site is being used at one’s own risk.
1,000 is what we hold, not what the city has ever published. A row we did not pull is not in the file. The portal itself stays free.
Person columns are stripped. The outbound name guard refuses a paid file whose header names a person or a way to reach one. Those columns stay in the city's portal and stay out of what we would sell.

See the file we hold
You do not have to take our word for what is in the file. Here are 25 rows of the real thing, carrying all 41 of its columns, cut out of the dated copies we sealed ourselves. Nothing in it is made up and nothing in it is tidied up.
- Open the 25 rows as a CSVA plain spreadsheet file. It saves to your machine rather than painting itself into a browser tab, and it opens in Excel, Numbers or Google Sheets.
- The same 25 rows as JSONThe same rows again, laid out for reading with code.
Nothing on this page is for sale. The sample file is free to read, and so is every row on the page above it.
