For existing buildings, Chicago uses Title 14X of the Municipal Code, Minimum Requirements for Existing Buildings. It replaced the old maintenance chapter, 13-196, on July 1, 2020. It sits inside the Chicago Construction Codes alongside the administrative, building and rehabilitation titles. It applies to every existing building, from a two-flat to a high-rise, and an inspector can cite it after a 311 complaint.
Chicago does not have one building code. It has a family of titles, and which one your building falls under depends on whether you are maintaining what stands or building something new. For a building that already exists, the title that matters most is 14X. If a violation notice is why you are asking, this piece explains where the rule comes from. Our guide to Chicago building violations covers what to do about the notice itself.
What the rule says
The Chicago Construction Codes are a set of titles in the Municipal Code. The City lists them as 14A Administrative Provisions, 14B Building Code, 14R Building Rehabilitation, 14X Minimum Requirements for Existing Buildings, plus separate titles for electrical, plumbing, fuel gas, mechanical, fire prevention, conveyance devices and energy (City of Chicago). The names tell you what each one is for.
Title 14X is the one written for buildings that are already built. It superseded the older retroactive maintenance provisions, mainly Chapter 13-196, on July 1, 2020 (City of Chicago). That date explains a lot of confusion. Pre-2019 chapter numbers still show up in older City documents and on contractor websites, but current work is governed by Titles 14A, 14B, 14R and 14X (City of Chicago).
On the exterior, 14X is blunt. The exterior of a structure must be kept in good repair, structurally sound and sanitary. The unsafe conditions it lists include masonry joints that are not weather resistant or water tight, veneer, cornices, trim and facings that are not properly anchored, and exterior stairs, decks, porches and balconies, including guards and handrails, that are not structurally sound or anchored (Title 14X). The City's text is long. This is the part owners meet most.
Who it applies to
Every existing building, of any height. The City's Exterior Wall Program, with its required reports, is aimed at high-rise buildings, so a typical two-flat or three-flat is not in that program. But the 14X exterior duties still apply to it, and an inspector can cite loose masonry, a parapet, a cornice or a lintel after a 311 complaint (City of Chicago).
That is the part that surprises owners. No program has to select your building. Nobody has to schedule an inspection. A neighbor calls 311 about a loose brick near the roofline, and 14X is the yardstick the inspector uses. For how that call turns into a visit, see how often Chicago inspects buildings.
What it means in practice
Think of the Chicago Construction Codes as three questions.
| Your situation | Where to look |
|---|---|
| Keeping an existing building safe and sound | Title 14X, minimum requirements |
| Doing repair or alteration work on an existing building | The permit rules in 14A, and the rehabilitation title 14R where it applies |
| Building new | The Building Code, Title 14B |
That table is a map, not a ruling. Which title controls a particular job is a question for the Department of Buildings or the architect on the project. We do not guess at it for you.
Two practical points follow.
The permit and the code are separate questions. A building permit is required before beginning most construction, demolition, rehabilitation and repair work, with a limited exempt list. Work that is exempt from a permit must still comply with all of the construction codes (City of Chicago). "No permit needed" never means "no code applies."
The date matters for new work. The 2019 Building Code and Rehabilitation Code were optional starting December 1, 2019, and became mandatory for most permit applications started on or after August 1, 2020 (City of Chicago). So a repair designed today is held to the current titles, not the ones your building was built under.
On brick two-flats and three-flats, a notice citing "exterior maintenance" almost always traces back to the same short list: open mortar joints, loose brick or coping near the roof, and wood back porches with soft framing. The building was often fine to its builders. The condition is what gets cited, not the year of construction.
If you are asking whether an old building is exempt from new rules, that is a different and trickier question. We take it up in old building, new code: are you grandfathered. Short version: the maintenance duties in 14X apply to buildings that already exist, and anything beyond that is for the Department of Buildings to confirm.
Reading the numbers on your notice
Look at the code section the notice cites. Anything with a 14X in it is a current existing-building maintenance section. A reference to chapter 13-196 or another old "13" chapter means the case is older, from before the July 2020 switch (City of Chicago). Either way the cited section tells you what the inspector found, and the repair is what closes the issue.
Our breakdown of what a violation notice really says goes line by line, and the most common exterior violations on two-flats shows how the code language turns into real conditions.
A 14X condition does not expire because nobody looked at it. Once a complaint is reviewed, the inspector can write violations for what is observed, including stairs and porches used to get out of the building (City of Chicago). Fixing a condition after a notice is slower and more expensive than catching it early, and the case keeps moving whether or not you answer.
Where we come in
We are a Chicago contractor, not the Department of Buildings and not your attorney. We read the section your notice cites, look at the actual condition, and tell you what the repair involves, whether it needs a permit, and what proof to bring. The paperwork is in English or Spanish.

Common questions
Chicago uses the Chicago Construction Codes, a set of titles in the Municipal Code. They include the Building Code (14B), the Rehabilitation Code (14R), Administrative Provisions (14A) and Minimum Requirements for Existing Buildings (14X), plus separate titles for electrical, plumbing and other systems.
Title 14X, Minimum Requirements for Existing Buildings. It superseded the older maintenance provisions, mainly Chapter 13-196, on July 1, 2020. Repair or alteration work can involve other titles, so confirm with the Department of Buildings which ones apply to your project.
The City's own descriptions say the Chicago Building Code (14B) is based on the 2018 International Building Code and the Rehabilitation Code (14R) on the 2018 International Existing Building Code. Chicago adopts its own versions, so use the Chicago titles, not the model code.
Its exterior must be maintained under Title 14X like any existing building, and new repair work is designed to the current titles. Whether a specific older feature is allowed to stay is a question for the Department of Buildings. See our article on grandfathered buildings.
