Pin it, photo it, submit it straight to 311 — then stick around. Offendr is where your block comes alive: live incidents, local news, fix-it projects, and the people making it happen.
The city's 311 portal works, but it's slow. Offendr gets you from "I hit that again" to a filed report before you reach the next block — and keeps you posted until it's fixed.
Quick email sign-in, then you're set for every future report. Your GPS location pins automatically when you open the report screen.
A photo strengthens your report and helps the city prioritize. Offendr resizes and attaches it automatically — no separate upload steps.
Your report goes directly to Chicago 311 via the Open311 API. You get a service request number immediately.
Offendr polls 311 and updates your report's status automatically — Open, In Progress, Completed — without you checking manually.
Reporting an issue is one thing. Offendr keeps you connected to everything else happening in your neighborhood — the problems, the projects, the people fixing things, and the good stuff too.
See every active report within walking distance of your location — potholes, graffiti, flooding, abandoned vehicles, streetlight outages and more. If someone on your block already reported it, you'll know before you file a duplicate. Confirm it instead and add weight to the existing request.
Always onBeyond 311 requests, neighbors can start fix-it projects — a block cleanup, a garden restoration, a graffiti removal effort — and invite others to join. Projects live on the map as their own pins and move from active to completed when the work is done. It's the part of civic life that 311 can't touch.
Organize togetherOffendr's feed mixes incident reports with real local news from Chicago sources — Block Club Chicago, the Tribune, NBC Chicago and more — surfaced by proximity to what you're already looking at on the map. No algorithm optimizing for outrage. Just what's happening near you.
Stay informedOffendr surfaces local volunteer opportunities from Chicago organizations alongside neighborhood incidents — because not every problem gets solved by a 311 report. Park cleanups, community gardens, mutual aid networks. Good things happening on your block deserve the same visibility as the bad ones.
Give backCommunity members can share events — block parties, farmers markets, neighborhood meetings, local fundraisers — pinned to the map so they show up for the people who actually live nearby. Your neighborhood's calendar, built by the people in it.
What's on near youChicago's freeze-thaw cycle is notoriously brutal on pavement. Water seeps into cracks during autumn, freezes and expands in winter, and leaves behind road damage that compounds with every vehicle that passes over it. By late February, Chicago streets can resemble a war zone — and the city relies on resident reports to know where to send repair crews.
The city of Chicago repairs hundreds of thousands of potholes every year, but the system is reactive: crews go where reports tell them to go. An unreported pothole is an unfixed pothole. When you file a report through Offendr, you're not just registering a complaint — you're triggering the actual repair dispatch process via Chicago's Open311 API.
Chicago targets a 3 business day response time for pothole repairs under its 311 service commitment. In practice, turnaround depends on weather, the current repair backlog, and how many reports have come in for the same location. Multiple independent reports of the same pothole generally accelerate response — which is why Offendr shows existing nearby reports and lets you confirm them rather than creating a duplicate.
If a pothole is causing immediate danger — unusually deep, in a high-traffic lane, or has already caused vehicle damage — you can call 311 directly to flag it as urgent. For vehicle damage claims, the City of Chicago has a process through the Department of Finance. A timestamped, geolocated Offendr report serves as supporting documentation for that claim.
Beyond potholes, Offendr routes reports for graffiti, flooding, abandoned vehicles, streetlight outages, illegal dumping and more — all going to the right city department through the same 311 system, from the same app you're already using to stay connected to your neighborhood.
Everything you need to know about reporting and tracking pothole repairs in Chicago.
Report that pothole, see what's happening on your block, and stay connected to the people making Chicago better — one fix at a time.
