Chicago uses the CHI311 system for reporting non-emergency code violations. Residents can call 311, visit 311.chicago.gov, or use the CHI311 mobile app. The Department of Buildings, Department of Streets and Sanitation, and other agencies handle violations based on type.
CHI311 is Chicago's non-emergency service request system. Residents can access it by calling 311, visiting 311.chicago.gov, or using the CHI311 mobile app (available on iOS and Android). The system routes complaints to the appropriate department: Department of Buildings handles structural safety, unpermitted work, and building code violations. Department of Streets and Sanitation handles sanitation code violations including overflowing dumpsters, garbage in alleys, and graffiti. The Department of Planning and Development handles zoning violations. Service requests can be submitted 24/7 online and via the app. Phone service is available 24/7. Residents can track request status online, receive updates, and submit photos with their requests. Each request receives a unique tracking number. The 311 Service Requests dataset is publicly available through the Chicago Data Portal for transparency.
Building code violations can result in fines from $500 to $1,000 per day per violation. Sanitation code violations typically carry fines of $300-$600. Repeat offenders face escalating penalties. The City may seek demolition orders for severely deteriorated buildings.
