Quick Answer About Dangerous Stairs or Steps:
If you fell on stairs that were too steep, too uneven, missing handrails, poorly lit, or built without proper anti-slip surfaces, the property owner may have violated building code requirements — and that violation can be powerful evidence in a premises liability claim. One step that’s even slightly shorter than the others can cause what experts call an “airstep” fall, where your body doesn’t have time to react before you’re falling.
Imagine you’re walking down a staircase you’ve used a hundred times. Nothing feels different. But on this trip, your foot drops a little further than it should — just an inch, maybe less — and before your brain can catch up, you’re tumbling. That split-second gap between “everything’s fine” and “I’m on the ground” is often the result of a defect that’s been there the whole time, hiding in plain sight.
Stairs are one of the most overlooked hazards on both commercial and residential property. Most people assume a fall on the stairs is just clumsiness — theirs or someone else’s. But often, it’s the stairs themselves that are dangerous.

What Makes Stairs Dangerous?
Building codes exist for a reason: stairs are deceptively complex pieces of architecture, and small mistakes in construction can create serious risks. Here are the defects we see most often when we investigate a stairway fall case:
Uneven riser heights or tread depths
When one step is taller, shorter, deeper, or shallower than the others
Missing or improperly installed handrails
Handrails that don’t meet code height, aren’t continuous, or aren’t anchored properly
Worn, slick, or smooth treads
Stairs with no anti-slip surface, especially dangerous when wet
Poor stairwell lighting
Dim or burned-out lighting that makes it hard to judge depth and distance
Landings that are too small or sloped unevenly
Landings that don’t give your foot a stable, level surface to land on
Any one of these can cause a fall. Combine two or three, and the risk multiplies.
The “Airstep” Danger: Why Small Differences Matter So Much
Here’s something most people don’t realize: a step that’s even an inch shorter than the others can be more dangerous than a step that’s missing entirely.
This creates what is called an “airstep.” When you walk down stairs, your body builds a rhythm — your brain expects each step to be roughly the same height as the last one. Researchers in human factors and biomechanics have studied this extensively, and the findings are striking: a riser that’s just half an inch to an inch shorter than the others (some studies point to differences as small as under 7 inches in step height) can be enough to throw off that rhythm and cause a terrible fall.
Why? Because your body doesn’t have time to react. The discrepancy is too small to see, but too large for your foot to “catch” the unexpected drop. Your foot travels further than expected, your center of gravity shifts forward, and by the time your brain registers something is wrong, you’re already falling.
This is why an “obvious” hazard — like a broken step or a big hole — isn’t always the most dangerous one. Sometimes it’s the step that looks perfectly normal that causes the worst falls.
Bold takeaway: If a staircase looks fine but something felt “off” right before you fell, that’s not a coincidence — it could be evidence of a code violation that’s hard to see with the naked eye but easy for an expert to measure.
Why Building Codes Matter to Your Case
Stair dimensions, handrail specifications, lighting requirements, and landing sizes are all governed by specific building code provisions — often the Virginia Uniform Statewide Building Code, which incorporates national model codes. These codes set minimum and maximum measurements for things like:
- Riser height (how tall each step is)
- Tread depth (how deep each step is, front to back)
- Riser height consistency (how much variation is allowed between steps)
- Handrail height, graspability, and continuity
- Required lighting levels in stairwells
- Landing dimensions
When a property doesn’t meet these requirements, that violation can become important evidence. It helps answer a question that’s often at the heart of these cases: did the property owner know, or should they have known, that this staircase was dangerous?
A code violation doesn’t just show that something was wrong — it shows that the danger was measurable, predictable, and preventable.
How We Investigate These Cases
Stairway defects are often subtle. That’s part of what makes them dangerous — and part of what makes them hard to prove without the right approach. Here’s what a thorough investigation typically involves:
- Documenting the scene quickly. Stairs get repaired, replaced, or modified — sometimes within days of an incident. Measurements, photos, and video need to happen as soon as possible.
- Measuring against code. We compare the actual riser heights, tread depths, handrail specifications, and landing dimensions against the applicable building code requirements.
- Reviewing maintenance and inspection records. Was this defect reported before? Did the property owner have notice?
- Consulting human factors and biomechanics experts. These experts can explain — in terms a jury can understand — exactly why a small dimensional difference creates an outsized risk of falling, and how that risk connects directly to your injury.

What to Do If You’ve Fallen on Defective Stairs or Steps
If you’ve recently fallen on a staircase and suspect something about the stairs themselves wasn’t right, here’s what can help protect your claim:
- Take photos and video of the staircase or step, including close-ups of the steps, handrails, and lighting — from multiple angles, if you’re able
- Note the time and lighting conditions when the fall happened
- Write down what you remember about how the fall happened, even small details like “my foot felt like it dropped further than I expected”
- Seek medical attention and follow through with treatment — both for your health and for documentation
- Don’t wait to talk to an attorney — stairs can be repaired or altered quickly, sometimes erasing the evidence
Frequently Asked Questions
Do I have a case if I just “tripped” on the stairs?
Maybe. Many falls that seem like “just tripping” are actually caused by a measurable code violation — uneven risers, inadequate lighting, or a missing handrail. An investigation can determine whether the stairs themselves played a role.
What if the staircase has since been repaired or replaced?
This is common, and it’s one reason to act quickly. Photos, witness statements, maintenance records, and even prior complaints can still help establish what the staircase looked like at the time of your fall.
Can a small height difference between steps really cause a serious fall?
Yes. This is one of the more counterintuitive aspects of stairway safety. A small inconsistency in step height can be more dangerous than an obvious hazard, because it doesn’t give your body time to adjust.
What evidence is most helpful in these cases?
Photos and video taken close in time to the fall, medical records documenting your injuries, and — where available — measurements of the staircase compared to building code requirements.
