Chicago’s Dangerous Parapets: Spot Problems Before Violations or Repairs Spiral
Chicago’s Brick Parapets: Out of Sight, but Not Out of Danger
Parapet walls might not be the most glamorous part of a building, but in Chicago, they’re a ticking time bomb if neglected. You’ve probably seen them—those short brick walls rising just above the roofline. They might look solid, but a failing parapet can lead to crumbling masonry, falling debris, and yes, a big fat violation notice from the City of Chicago.
The worst part? Many property owners don’t even realize there's a problem until inspectors do. In this guide, we’ll walk you through what a parapet wall is, why they become dangerous, how to spot early warning signs, and what to do before a minor issue turns into a structural headache.
What Is a Parapet Wall (and Why It’s Worth Paying Attention To)
A parapet wall is an extension of your building’s wall that rises above the roof, usually at the edges. In older brick buildings across Chicago—especially in two-flats, greystones, and commercial mixed-use properties—these parapets are everywhere. They’re often decorative, sometimes functional, and almost always forgotten about until something starts to deteriorate.
Why should you care? Because over time, parapets are exposed to some of the harshest weather conditions imaginable: heavy snow, driving rain, wild temperature swings, and that classic Midwest wind that doesn’t quit. And all that exposure leads to wear and tear—on the mortar joints, brickwork, and sometimes even embedded metal supports—which eventually puts the structure at risk.
Why Parapets in Chicago Are So Vulnerable
Chicago’s weather isn’t known for being gentle. One week it’s 70 degrees and sunny, and the next we’re shoveling snow in April. These dramatic swings wreak havoc on masonry. Mortar begins to deteriorate, cracks widen, water seeps in, and before you know it, your parapet wall is slowly starting to lean, crumble, or even collapse.
Here’s the thing—most parapet walls in Chicago haven’t been touched in decades. They were built at a time when construction standards were different, and many used softer mortar or lacked proper flashing. Combine that with rusting lintels, shifting brick, and deteriorating coping stones, and you’ve got a recipe for a major repair waiting to happen.
And it’s not just about property damage. Falling masonry from a dangerous parapet wall can cause serious injury, sidewalk closures, or city-imposed emergency scaffolding—all of which you’re going to have to pay for. And all realistic things that we have seen in our many years as a local Chicago masonry repair company.
6 Warning Signs That Your Parapet Wall Might Be Dangerous
Most parapet wall failures don’t happen overnight. They start with small, often-overlooked signs. Catching these early can save you money, stress, and possibly a visit from a city inspector.
Here’s what to look out for:
1. Cracked or Bulging Bricks
If you see cracked bricks, gaps in the wall, or bricks that look like they’re puffing outward, that’s a sign of internal pressure and structural breakdown. Bulging usually means moisture has penetrated behind the brick—and that’s bad news.
2. Missing Mortar Joints or Leaning Sections
Damaged mortar is a big red flag. When joints begin to erode, the brick wall loses its integrity. Look for leaning segments, stair-step cracks, or places where the parapet seems to be pulling away from the roofline.
3. Loose or Missing Coping Stones
Coping stones are the “caps” on top of the parapet that help shield it from water. If they’re loose or gone, moisture will start entering the entire structure below—fast.
4. Moisture Stains or Efflorescence
White powdery stains on your brickwork (aka efflorescence) are caused by water movement. It's the building trying to talk to you—and it's not whispering.
5. Gaps at the Roofline
A clear sign something is shifting. You might see visible daylight, sagging flashings, or separations between the roof and the wall.
6. Fallen Debris Near the Building
If you find pieces of brick or mortar near your foundation or sidewalk—your parapet wall may be shedding. That’s not just deterioration—that’s liability.
What Happens When the City Flags Your Parapet
If a City of Chicago building inspector notices unsafe masonry, especially on the parapet, you’ll likely receive a City of Chicago masonry code violation notice. That’s when the real fun begins.
You'll be required to:
Hire a licensed masonry contractor to inspect and complete the repairs
Potentially install scaffolding or sidewalk protection
Submit documentation showing the issue has been resolved—on a deadline
Delaying this process? That can lead to mounting fines, court dates, and even forced access to the building for emergency work. The cost of ignoring a notice will almost always exceed the cost of proactive maintenance. And let’s not forget the stress of navigating city red tape when you’re already behind the eight ball.
How to Get Ahead: Inspections and Preventative Repair
The good news? Most of this can be avoided with some old-fashioned prevention. A yearly inspection, especially after a tough winter or major storm, can help you spot small issues before they spiral.
A licensed professional mason will assess:
The condition of mortar joints
Stability of brick layers and coping stones
Flashing integrity where roof meets wall
Any hidden structural shifts that you might miss from the ground
Think of it like a check-up for your building. It’s easier (and cheaper) to treat early symptoms than wait for a full-blown emergency.
