To look up building violations for a Chicago address, search the Department of Buildings’ Building Permit and Inspection Records site. The city’s search page says an address search returns permits, inspections, enforcement case activity and the violations inspectors cited. Each violation shows a status: Open, Complied or No Entry.
For violations cited because work was done without a permit, Open is the usual answer. We followed the 1,446 Chicago inspections in 2024 that cited a no-permit violation. By October 2026, 23% had every one of those violations marked Complied, 43% had a building permit applied for at the same address within a year, and 40% had gone to the Department of Administrative Hearings, where about half of the cases were non-suited (dismissed).
How to look up building violations for a Chicago address
- Open the Department of Buildings’ Building Permit and Inspection Records search and enter the street address.
- Read each violation’s code, date and status. The city’s Building Violations data defines Complied as addressed, Open as still open, and No Entry as an inspection where the inspector could not get inside.
- Write down the inspection date. Building cases heard by the Department of Administrative Hearings (DOAH) are listed by address in the city’s Ordinance Violations data, with docket number, hearing date, disposition and fine.
- Check the Circuit Court of Cook County separately. The Ordinance Violations data covers administrative hearings only, and the most dangerous building cases go to Circuit Court.
- For a closing, use the title commitment. The Building Violations data itself tells lenders and title companies to check the title commitment for outstanding enforcement actions in Circuit Court or at Administrative Hearings.
How a Chicago building violation moves to a hearing
The Department of Buildings’ enforcement process summary describes three notice levels set by a supervisor. A 20 notice is a warning for maintenance violations. A 50 notice sends life-safety violations that are not dangerous to Administrative Hearings, and an 80 notice sends dangerous and hazardous conditions to Circuit Court.
An owner who has finished the work can avoid an in-person hearing by emailing evidence such as photos, repair invoices and paid receipts. If the department accepts it, a DOB representative asks for the case to be non-suited, which dismisses it, according to DOAH’s compliance evidence notice. A liable finding is a final order; DOAH’s Buildings Division FAQ says it can be appealed to the Circuit Court within 35 days, and points owners with a lien from an Administrative Hearings judgment to the Department of Revenue (312-742-3317).
What 1,446 Chicago no-permit citations from 2024 show
We pulled every Department of Buildings violation dated 2024 that carries one of eight no-permit codes in the city’s Building Violations data: plans and permits required (NC2010, NC2011), permit required (NC2020, NC2021), plumbing work without a permit (PL171017, PL232011, PL232040) and wiring without a permit (EL1891). That came to 1,622 violations from 1,446 inspections at 1,325 addresses. Almost all of them (99%) were cited at inspections triggered by a 311 complaint.
| Inspecting bureau | Inspections | All no-permit violations Complied by Oct. 2026 | Permit applied for within 12 months |
|---|---|---|---|
| Conservation | 717 | 26.4% | 35.4% |
| New Construction | 610 | 16.9% | 51.6% |
| Plumbing | 71 | 59.2% | 35.2% |
| Electrical | 35 | 8.6% | 62.9% |
| All bureaus | 1,446 | 23.4% | 42.9% |
When a citation does reach Complied, it takes most of a year: a median of 289 days from the inspection, and a quarter took 440 days or more. In the city’s data as of October 24, 2026, 1,232 of the 1,622 violations still read Open. The All bureaus row includes 13 inspections by smaller units such as the Special Task Force.
Did a building permit follow the violation?
For 620 of the 1,446 inspections (42.9%), someone applied for a permit at the same street address within 12 months, and that permit had been issued by October 2026. The median application came 98 days after the inspection, three in four within 192 days, and the median issue date was 148 days after the inspection. We counted building, renovation, express, new construction and demolition permits from the city’s Building Permits data, leaving out signs and elevator equipment.
Inspections followed by a permit were three times as likely to have their no-permit violations marked Complied: 37.7%, against 12.7% where we found no permit. A permit that later reads Complete is the record to look for; see our Chicago building permit search guide for reading its status.
What happened to the cases at Administrative Hearings
We matched the inspections to Buildings cases in the Ordinance Violations data by street address and a violation date within three days. 574 of the 1,446 inspections (39.7%) had a DOAH case. The latest hearing date was a median 236 days after the inspection.
| DOAH outcome | Inspections | Permit applied for within 12 months | All no-permit violations Complied |
|---|---|---|---|
| Non-suit (dismissed) | 273 | 68.5% | 43.2% |
| Liable | 108 | 41.7% | 19.4% |
| Default | 178 | 33.1% | 5.6% |
| Not liable | 8 | 8 of 8 | 8 of 8 |
| No DOAH case found | 872 | 36.6% | 20.9% |
Seven more cases were still on continuance or had another disposition. Liable and default orders carried a median fine of $1,000; the middle half ran from $500 to $1,000, nine in ten were $2,500 or less, and the highest was $7,500. Default orders had the lowest compliance rate of the main outcomes. DOAH’s FAQ explains that an owner who was wrongly named can file a motion to set a default aside.
Checklist for a Chicago address with a no-permit violation
- The violation code, inspection date and status in Building Permit and Inspection Records.
- A permit at the same address dated after the inspection, and whether it now reads Complete, Active, Expired or Suspended.
- The DOAH docket for the same inspection date in the Ordinance Violations data: the disposition and any fine.
- For a liable or default order with a fine, whether a lien followed; DOAH’s FAQ sends owners to the Department of Revenue for liens from its judgments.
- The title commitment, for open actions in Circuit Court or at Administrative Hearings.
- The work you can see at the property against the permit’s work description.

Counts are our calculations from the City of Chicago’s Building Violations, Building Permits and Ordinance Violations data, pulled October 24, 2026. Records were matched by street address, so a permit filed under another number in an address range would be missed, and the permit data lists issued permits only. City pages checked October 24, 2026.
