Chicago 311: report an issue, and explore every request on a map

Two things live here: how to report a problem to the City of Chicago, and how to read the resulting 311 data as a map. Enter an address to see recent requests near a parcel.

Report a problem to the City of Chicago

To file a 311 request — a pothole, missed pickup, building-code violation, graffiti — contact the City’s CHI311 service directly:

  • Online: 311.chicago.gov
  • By phone: 311 (or 312-744-5000 from outside the city)
  • On your phone: the CHI311 mobile app

Civic Worth is an independent synthesis of public records — it is not the City and does not receive or forward 311 reports. Use the channels above to file one.

Explore 311 as data

Every 311 request the City closes is published as open data. Civic Worth places each one on its parcel and rolls the results up by community area, so you can see how fast requests are resolved and where code-violation complaints cluster — not just your own request’s status. Start with the 311 response-time map and the code-violations map.
