No Building Permit and Construction Violation

Common questions

How do I file a "No Building Permit and Construction Violation" request with Chicago 311?

Three ways, all of which create the same public record: online at 311.chicago.gov, by calling 311 from inside the city (or 312-744-5000 from outside it), or through the CHI311 mobile app. Give the exact address or nearest intersection — requests without a usable location are the ones that stall. Requests of this type are routed to DOB - Buildings.

How many "No Building Permit and Construction Violation" requests does Chicago get?

35,350 have been filed in total, excluding duplicates the city flagged. 471 came in over the last 30 days, up 29% versus the previous 30 days.

How long does a "No Building Permit and Construction Violation" request take to close?

The city does not publish a target response time for this request type, and this page does not estimate one. What the data does show: 87% of all "No Building Permit and Construction Violation" requests are marked Completed and 13% are still Open. The rest were canceled — usually duplicates or requests that turned out to be someone else's jurisdiction.

Is my 311 request public?

Yes. Every service request becomes a public record in the city's open data portal, including the type, status, the street address (block level), the ward, and the dates it was opened and closed. That is exactly what this page is built from. Your name and phone number are not published.
