A building violation notice from the City of Chicago reads like it was written for lawyers, and the clock starts the day the inspector reports it. Most owners don't need to panic. They need to know which kind of case they're in, what the City wants to see, and who does what. This guide walks through the whole process in the order you'll live it.
If you only read one part, read this:
- Find out where your case is heard. Most building cases go to the Department of Administrative Hearings. Dangerous conditions go to housing court. The notice tells you which.
- Fix the actual condition, with a permit if the work needs one.
- Document the fix with the permit and before and after photos.
- Show up on the date on your notice, with that proof.
Everything below explains why those four steps matter and what happens when one gets skipped.
How Chicago building violations start
Most violations on occupied buildings start with a phone call, not a random inspection. The Department of Buildings reviews every 311 complaint at the start of each business day to decide which ones need an immediate visit (City of Chicago). Tenants, neighbors and passersby can all report a problem building through 311, including porch safety, construction without a permit, general safety and vacant buildings (Department of Buildings).
When the inspector comes out, they check the complaint and usually more. The City's own enforcement process says inspectors also look at smoke and carbon monoxide detectors and the ways out of the building, including interior and exterior stairs and porches, and write violations for what they find (City of Chicago). A complaint about one leaking ceiling can turn into a notice that lists the back porch.
If the inspector can't get in, the Department can leave a notice asking you to call, come back later, write up what it can see from outside, or close the complaint. If an owner or tenant refuses entry, the Department has to get a court order (City of Chicago). For more on that, see whether an inspector can walk into your building and how often Chicago actually inspects.
What rules the inspector is enforcing
Chicago's building rules live in the Chicago Construction Codes, a set of titles in the Municipal Code (City of Chicago). For buildings that already exist, the one that matters most is Title 14X, Minimum Requirements for Existing Buildings. It replaced the older maintenance chapter, 13-196, on July 1, 2020 (City of Chicago). If your notice cites a 13-196 section, it's an older case.
Title 14X says the exterior of a building must be kept in good repair, structurally sound and sanitary. The unsafe conditions it lists include masonry joints that aren't weather-tight, loose cornices and trim, and exterior stairs, decks, porches and balconies that aren't sound (Title 14X). That's why so many exterior violations on Chicago two-flats come down to mortar, porches and parapets. We cover the usual suspects in the most common violations on two-flats, and the question of older buildings and newer rules in what code Chicago uses for existing buildings.
On brick two-flats and three-flats, the exterior violations we're called about most often are open mortar joints, loose or spalling brick near the roofline, and wood back porches with soft posts or loose railings. They're rarely surprises to the owner. They're things that got put off one more season.
Three levels of violation, two places your case can go
According to the City's published enforcement process, a Department of Buildings supervisor sets the level of each case (City of Chicago):
| Level | What it covers | Where it goes |
|---|---|---|
| "20" notice | Maintenance violations | Warning notice |
| "50" notice | Life safety, not dangerous | Department of Administrative Hearings |
| "80" notice | Life safety, dangerous and hazardous | Circuit Court of Cook County |
Most owners end up at Administrative Hearings, often called DOAH. It's a civil proceeding with a hearing officer, not a criminal court. Dangerous cases go to housing court in the Circuit Court of Cook County, where the City has more tools: it can ask to vacate the building, appoint a receiver, set case management dates and negotiate consent decrees. A court inspector is assigned and inspects before each court date (City of Chicago). The details of each track are in hearing officer or circuit court.
One point that saves owners time: the hearings department doesn't investigate or prosecute anything. The Department of Buildings files the case, and questions about why you were cited go to the Department of Buildings, not to the hearing office (Department of Administrative Hearings).
How to read your violation notice
The notice generally tells you three things: what the alleged violation is; the date, time and place it was found; and your options, which can include paying by mail where that's allowed, a mandatory appearance, or how to request a hearing. If you must appear, it gives the date, time and place (Department of Administrative Hearings).
For building cases at Administrative Hearings, the hearing can't be set less than 30 days after the inspector reports the violation, except in emergencies. The City can serve notice in person, by mail, or, if those fail, by posting it on the building at least 20 days before the hearing (Municipal Code 2-14-152). If you own a building you don't live in, that last part matters: a notice taped to the door still counts.
We break down every line of a typical notice in what a Chicago violation notice really says.
Fix it, document it, then show up
Here's the part that trips up careful owners. Fixing the problem doesn't close the case by itself. The City's own FAQ answers the question "I fixed it while the inspector stood there, why court?" directly: the Department alleges the violation existed on the inspection date, and the hearing is your chance to show proof that it's been corrected (Department of Administrative Hearings). We wrote a whole piece on why repairs alone don't close a case.
The good news is that the fix is your strongest move. Under the Municipal Code, defenses at a building hearing include that the violation didn't exist at inspection, or that it was corrected by the time of the hearing (Municipal Code 2-14-155). A case can end in a nonsuit when the owner has given timely proof the violations are fixed (City of Chicago).
What counts as proof? For a porch case at Administrative Hearings, the Department of Buildings tells owners to bring the permit and before and after photos to the hearing date (Department of Buildings). That's a good standard for most exterior repairs. Our list of what proof shows a violation is fixed goes further.
Two practical notes:
- Many fixes need a permit. Chicago requires a building permit before most construction, demolition and repair work, with a limited list of exemptions (City of Chicago). A repair done without a required permit can create a new problem while it solves the old one. See do you need a permit to fix a violation.
- If you're found liable but have started the work, the hearing officer can set a separate fines hearing within 30 days (longer for good cause) and can order a reinspection first (Municipal Code 2-14-156). Starting the work matters even if you can't finish before the first date.
Step by step instructions, from the first call to the final photos, are in how to fix a Chicago building code violation.
What happens at the hearing
The hearing officer at Administrative Hearings is a licensed Illinois attorney. It's a civil proceeding, and the City has to prove the violation is more likely than not. You can represent yourself, hire a lawyer, or in some cases use an authorized representative. The City's attorney may offer a settlement before the hearing, but doesn't have to (Department of Administrative Hearings).
What to bring, what to say, and how to organize your proof is in preparing for your building violation hearing. If you're weighing whether to contest the violation itself, that's a legal question: talk to an attorney. We explain the split in lawyer, contractor or both.
Fines, liens and the cost of waiting
Under the 2019 text of the Administrative Provisions, each violation of the Chicago Construction Codes is subject to a fine, and each day a violation continues counts as a separate offense (Title 14A, 2019 text). Current amounts change and depend on the violation, so confirm them with the Department of Buildings or your attorney. Our fines explainer covers how they're assessed.
Liens are where an ignored case gets expensive. A default judgment can be used to place a lien on the property, garnish wages and affect credit (Department of Administrative Hearings). For buildings declared a public nuisance, fines and any City repair, demolition or receivership costs become a lien, and the City's own costs can come ahead of earlier liens except taxes (Title 14A, 2019 text). See how a building violation lien gets released.
Skip the hearing and the case can go to default. The City usually asks for the maximum fine in default matters, and a default judgment can lead to a lien, wage garnishment and credit damage. A written motion to set aside a default generally has to be filed within 21 days of the mailing date on the default order, and a final order can be appealed to the Circuit Court of Cook County within 35 days (Department of Administrative Hearings). Those are short windows. If you've already missed a date, see setting aside a default and talk to an attorney quickly.
Dangerous buildings and housing court
An "80" notice is a different situation. In the Circuit Court of Cook County, the City can ask the judge to vacate the building, appoint a receiver to take control of repairs, or enter a consent decree with deadlines. A court inspector checks the building before each court date, and the City's lawyers ask for missing smoke and carbon monoxide detectors to be fixed within 24 to 48 hours of the first court date (City of Chicago).
If you're in housing court, the repair schedule is no longer just yours to set. Get an attorney involved, and line up the contractor before the first date so you can tell the judge who is doing the work and when it starts. See order to vacate for what happens when it goes that far.
Looking up violations, buying and selling
You can search permit, inspection and violation records by address through the Department of Buildings' records search, and the Chicago Data Portal publishes building violations issued since 2006 (City of Chicago). See how to look up violations by address.
Be careful using that data for a purchase. The City's own dataset notice says it is historical, shouldn't be relied on for real estate transactions, may not reflect current conditions, and includes both liable and not liable findings. It tells lenders and title companies to check the title commitment for open enforcement cases at Administrative Hearings or in Circuit Court (Chicago Data Portal). If you're buying, read buying a two-flat with open violations before you close.
Who does what: owner, contractor, attorney, expediter
A building violation case has a legal side and a physical side, and they need different people.
- You, the owner, are responsible for the case and the building. You decide whether to contest or fix, and you show up.
- An attorney advises on contesting the violation, defaults, appeals, liens and housing court. We don't give legal advice, and neither should your contractor.
- A licensed contractor fixes the condition, pulls the permits the work needs, and gives you the documentation the hearing officer will want to see.
- A permit expediter can help when the fix needs plans and a longer review. See what permit expediters do.
Akats handles the physical side and the City paperwork that comes with it, in English or Spanish. Our building code violation service page explains how we work a case from the notice to the final photos.
A step by step plan for the first two weeks
- Read the notice the day you get it. Write down the hearing date, the address, the case number and every listed violation.
- Figure out the level. Administrative Hearings or Circuit Court? If it's housing court, call an attorney now.
- Get the condition looked at. A contractor who knows Chicago violations can tell you which items are quick, which need a permit, and which need drawings.
- Decide fix or contest (with an attorney if you're contesting).
- Start the work, under a permit if one is needed. Take before photos first.
- Collect proof: permit number, invoices, after photos of each listed item.
- Go to the hearing with that proof, organized by violation.
Keep everything in one folder, on paper or on your phone: the notice, every letter from the City, the permit, invoices and dated photos. Label photos by violation so you can find them in front of the hearing officer. If you have tenants, tell them when work is scheduled and keep a record of when you asked for access. The Municipal Code lists an occupant refusing the owner entry to make repairs as one of the defenses at a building hearing (Municipal Code 2-14-155). Paperwork won't fix a porch, but it's what turns a fixed porch into a closed case.

Common questions
There's no single number for every case. For building cases at Administrative Hearings, the hearing can't be set less than 30 days after the inspector reports the violation, except in emergencies. Your notice gives the actual date. Start the repair as early as you can and bring proof to that date.
Not by itself. The Department of Buildings alleges the violation existed on the inspection date, so you still need to show proof of the fix, such as the permit and before and after photos, at your hearing.
Most building cases go to the Department of Administrative Hearings, a civil proceeding before an attorney hearing officer. Dangerous and hazardous conditions go to the Circuit Court of Cook County, where the City can seek a receiver, a vacate order or a consent decree.
The case can go to default, and the City usually asks for the maximum fine. A written motion to set aside the default generally must be filed within 21 days of the mailing date on the default order. Talk to an attorney quickly.
Often, yes. Chicago requires a permit for most repair work, with a limited list of exemptions. A repair done without a required permit can create a new violation. Ask your contractor to confirm before work starts.
Yes, through the Department of Buildings records search and the Chicago Data Portal. But the City says that data should not be relied on for real estate transactions. Have your attorney or title company check for open enforcement cases.
