A City of Chicago building violation notice names the alleged violation, the date, time and place it was found, and your options: pay by mail where allowed, a mandatory appearance, or a request for a hearing. The level a Department of Buildings supervisor assigns (20, 50 or 80) decides where the case goes. For building cases the hearing is set at least 30 days after the violation is reported. Ignoring the notice can lead to a default judgment.
A City of Chicago building violation notice is a short document with long consequences. It is written in the language of the Municipal Code, it may arrive by mail, by hand or taped to your door, and it carries a date you cannot afford to miss. Here is what each part tells you, so you can decide what to do before the date arrives.
This article reads the notice itself. For the whole path from complaint to cleared case, start with our guide to Chicago building violations.
Who sent the notice, and who can answer questions about it
In a building case, the Department of Buildings is the department that cited you. It files the Notice of Violation with the Department of Administrative Hearings. The hearings department does not investigate, file or prosecute cases, and it is the Department of Buildings you ask when you want to know why you were cited (Department of Administrative Hearings).
That split matters the first time you pick up the phone. If your question is "why does this say my back porch is unsafe?", it belongs to the Department of Buildings. If your question is about the hearing itself, check the contact details printed on your notice.
The three things every notice tells you
The City describes the notice as stating three things (Department of Administrative Hearings):
- The alleged violation. What the City says it found.
- The date, time and place it occurred. This is the inspection date. It is not the hearing date.
- Your options. These can include paying by mail where you are eligible, a mandatory appearance, or instructions for requesting a hearing.
Two details trip owners up. The first is the inspection date. The City alleges the condition existed on that day, so fixing it later does not erase the notice. It is your proof at the hearing, and we cover that in why repairs alone don't close a case. The second is the phrase "mandatory appearance." If your notice says you must appear, it also gives the date, time and place, and the City's own guidance is that ignoring a notice can lead to a default judgment (Department of Administrative Hearings).
What the 20, 50 and 80 mean
According to the City, a Department of Buildings supervisor sets the enforcement level (City of Chicago). The number tells you how serious the City considers the condition, and where the case is headed.
| Level | What the City means by it | What it means for you |
|---|---|---|
| 20 | Maintenance violations, a warning notice | A warning. Fix the condition and keep proof |
| 50 | Life safety, not dangerous | Goes to the Department of Administrative Hearings, a civil hearing officer |
| 80 | Life safety, dangerous and hazardous | Goes to the Circuit Court of Cook County, housing court |
Treat the number as your first triage. A 20 is the City telling you to get ahead of it. A 50 means a hearing date is coming, and the rest of this article is about that date. An 80 is the one to take to an attorney the same day, because housing court gives the City more options than a hearing officer has, including vacating a building or appointing a receiver. We compare the two tracks in hearing officer or circuit court.
What your options really are
The notice may list several ways to respond. They are not interchangeable.
- Mail-in payment, where it is offered. Whether to pay or contest is a decision about your rights and your record. Paying does not repair the building. If you are unsure, talk to an attorney before you send anything.
- Appear at the hearing. If the notice says appearance is mandatory, this is not optional. Bring proof of the repair. The City's defenses at a building hearing include that the violation did not exist or has been corrected, so your documents are your case.
- Request a hearing. If the notice says you may request one, the steps are on the notice itself. Follow them exactly and keep a copy of whatever you send.
None of these steps involves a contractor. But all of them go better when a contractor has already looked at the condition. We walk through the repair side in how to fix a Chicago building code violation, step by step.
How to count the days on your notice
There is no general "comply within X days" rule that we can point to in the City's materials, so do not rely on a number you heard from a neighbor. What the Municipal Code does set is the hearing date. For building cases it cannot be less than 30 days after the inspector reports the violation, except in emergencies. The City can serve the notice in person, by mail to the registered designee or address, or, if those fail, by posting it on the building at least 20 days before the hearing (Municipal Code 2-14-152).
In practice:
- The 30 days run from the date the inspector reports the violation, not from the day the letter reaches you.
- A notice posted on the door counts as service when the other methods fail. If you own a building you do not live in, ask a tenant or a neighbor to photograph anything taped up and send it to you.
- The date on the notice controls. If it says you appear on a given day, plan backward from that day for the repair, the permit and the photographs.
On Chicago two-flats and three-flats, the owners who get surprised are often the ones who live elsewhere. The notice lands on a door, a tenant mentions it weeks later, and the owner learns about it after most of the time before the hearing is gone. If you rent out a building, tell your tenants to call you the day anything is posted.
Reading the code section on the notice
Your notice names the code section behind each item. For existing buildings, the main set of rules is Title 14X, which replaced the older maintenance chapter 13-196 on July 1, 2020 (City of Chicago). If you see 13-196 cited, it points to an older case.
For exterior conditions, the 14X language is plain. The unsafe conditions it lists include masonry joints that are not water tight, loose cornices, trim and facings, and exterior stairs, decks, porches and balconies that are not structurally sound (Title 14X). When your notice cites one of these, you are not looking at a technicality. The City is saying a part of your building is not holding up. See what code Chicago uses for existing buildings for how the titles fit together.
What happens if you ignore the notice
Ignoring the notice can lead to a default judgment. A default judgment can be used to place a lien on the property, garnish wages and affect credit, and the City usually requests the maximum fine in default matters (Department of Administrative Hearings). The windows to undo a default are short, so do not wait to find out. We cover the whole chain in what happens if you ignore a Chicago building violation.
What to do with the notice today
- Write down the case number, the address, every item listed and the hearing date.
- Find the level: 20, 50 or 80. If it is an 80, call an attorney.
- Photograph the condition before anyone touches it.
- Have a contractor look at each listed item and tell you which ones need a permit.
- Put the notice, the envelope and any photos of a posted copy in one folder.

Common questions
They are enforcement levels set by a Department of Buildings supervisor. A 20 is a maintenance warning, a 50 is life safety but not dangerous and goes to Administrative Hearings, and an 80 is dangerous and hazardous and goes to the Circuit Court of Cook County.
For building cases, the hearing cannot be set less than 30 days after the inspector reports the violation, except in emergencies. Your notice gives the actual date, and that date controls. See how long you have to fix a violation.
The Department of Buildings. The Department of Administrative Hearings does not investigate, file or prosecute cases, so it cannot explain the citation. Your notice lists contact details.
It can be. If personal service and mail fail, the City can serve notice by posting it on the building at least 20 days before the hearing. If you own a building you do not live in, ask tenants to tell you about anything posted.
That is a legal decision about contesting versus accepting the violation, and paying does not repair the building. Talk to an attorney before you decide, and see your notice number and what it is for.
