The Trivial Defect Rule in New York

How Big Does a Sidewalk Defect Have to Be to Sue in New York?

There is no minimum size. New York's highest court has said so twice, in plain language.

A defect does not have to reach a certain height or depth to be actionable, and a judge may not dismiss a case based on the measurement alone.

That answer surprises people, because the first thing an adjuster says on the phone is that the crack was too small to matter.

What New York actually asks is whether the defect was physically insignificant under all the circumstances, and whether anything about it or its surroundings made it more dangerous than its size suggests.

A quarter-inch lip in a shadowed doorway on a crowded block is a different case from the same lip in the middle of an empty, well-lit walk.

Which is why the answer to this question never comes from a tape measure by itself.

Trincere v. County of Suffolk: The Case That Killed the Height Rule

That sentence comes from the New York Court of Appeals in 1997, and it has governed every sidewalk case in this state since.

The plaintiff in that case tripped over a concrete paving slab raised about half an inch above the slabs around it. The lower courts dismissed the claim as trivial on the measurement alone. The Court of Appeals held that granting summary judgment based exclusively on the dimension of the defect is unacceptable, and that a court has to consider all the facts and circumstances presented before deciding no issue of fact exists.

The Court also said something that gets quoted less often and matters just as much: whether a dangerous condition exists on someone's property so as to create liability is generally a question of fact for the jury.

So the half-inch rule people repeat does not exist. Neither does the inch rule, the three-quarter-inch rule, or any of the other numbers that circulate. What survives is a standard, and a standard is something a lawyer can work with.

The Eight Factors New York Courts Weigh Instead of a Measurement

Courts examine the width, depth, elevation, irregularity, and appearance of the defect, along with the time, place, and circumstance of the injury. Five physical characteristics and three contextual ones, considered together.

• Width. A hairline separation and a two-inch gap present entirely different hazards at the same depth.
• Depth. How far the surface drops, measured at the deepest point rather than the average.
• Elevation. The height differential between adjacent surfaces, which is what actually catches a toe.
• Irregularity. Whether the edge is smooth and rounded or jagged, broken, and unpredictable.
• Appearance. Whether the defect reads as a hazard or blends into the surrounding surface in color and texture.
• Time. Daylight, dusk, or dark, and what the artificial lighting at that location actually does.
• Place. A busy commercial corridor where pedestrians cannot look down, a subway entrance, a doorway, the bottom of a stair.
• Circumstance. Crowd density, weather, debris or leaves covering the defect, and whether anything drew the eye away from the pavement.

The Court of Appeals has been direct about what this list is for. Physically small defects are actionable when their surrounding circumstances or intrinsic characteristics make them difficult for a pedestrian to see, difficult to identify as hazards, or difficult to traverse safely on foot.^[1] That is the whole test, and every one of those conditions is something a photograph can capture.

What Hutchinson Decided in Three Cases With Different Measurements

In 2015 the Court of Appeals took three trivial defect appeals together in Hutchinson v. Sheridan Hill House Corp. and reversed the dismissal in two of them. The three outcomes are the clearest map available of where this doctrine actually lands.

Read across that table and the pattern is not about size. The quarter-inch defect lost because everything around it was benign: good light, open sidewalk, no crowd, a smooth edge, nothing hiding it. The half-inch defect survived because it sat on the part of a step where a foot lands. And the third case never got to the measurement at all, because a defendant that cannot say how big the defect was cannot prove it was small.

Who Has to Prove What, and Why That Order Matters

The trivial defect argument arrives as a motion for summary judgment, which means the defendant is asking a judge to end the case before a jury hears it. Summary judgment has an order of proof, and in these cases the order does a great deal of work.

A defendant seeking dismissal on triviality must make a prima facie showing that the defect is, under the circumstances, physically insignificant, and that the characteristics of the defect or the surrounding circumstances do not increase the risks it poses. Only then does the burden shift to the injured person to establish an issue of fact.

Both halves have to be satisfied. A defendant who proves the defect was small but says nothing about lighting, crowd, edge condition, or visibility has proved half of a two-part showing and is not entitled to anything. The Court of Appeals summarized the point in a single line worth remembering: there are no shortcuts to summary judgment in a slip-and-fall case.

This is why a case that looks weak on the measurement can still be a live one. The question in the first instance is not how big the defect was. It is whether the party moving to dismiss can carry a burden it frequently ignores.

Small Defects That Are Still Actionable: Traps, Snares, and Bad Light

The recurring winners in this category share a feature. The defect is modest in size and difficult to perceive or to cross, and the two together produce a fall that a larger, obvious defect would not have caused.

• Same-color defects. A gray lip in gray concrete with no shadow line, invisible from a walking posture even in daylight.
• Defects in a shadow or a dead spot. Under an awning, at a doorway, beside a column, or on a block where the nearest streetlight is out.
• Metal hardware protruding from pavement. Sheared bolts, sign post stubs, and old anchor points, which have jagged edges and grab a shoe rather than letting it slide.
• Edges on stair nosings. Where the foot lands, a small chip is functionally different from the same chip on the flat of the tread.
• Defects hidden by leaves, water, snow, or debris. Nothing about the defect changes, but its visibility drops to zero.
• Repeating gaps in a crowded corridor. On a sidewalk where pedestrian density forces people to watch ahead rather than down, a defect nobody can look at is a defect nobody can avoid.

Note also what the Court of Appeals told lower courts to stop doing. In deciding whether a defendant has shown triviality, a court must avoid asking whether the plaintiff might have avoided the accident by putting their feet somewhere else. That is a comparative fault argument dressed up as a legal ruling, and it belongs to a jury.

The Doctrine Applies to Landlords and Interior Stairs, Not Only City Sidewalks

One of the Hutchinson plaintiffs argued that the trivial defect rule should be limited to municipalities and to outdoor sidewalks, on the theory that a city cannot be expected to police every inch of pavement while a building owner can be expected to keep a lobby stair uniform.

The Court declined. The principle underneath the doctrine spans all types of liability: where a defect is so slight that no careful or prudent person would reasonably anticipate danger from it, there is no liability, and that applies equally to private landlords and to municipalities. The doctrine has been applied to stairways inside privately owned buildings for decades.

So the same analysis governs a chipped step in an apartment building lobby, a lifted tile in a store, a worn tread in an office stairwell, and a raised flag on a public sidewalk. What differs is the context: pedestrians reasonably expect an interior walking surface to be more uniform than weathered concrete, and that expectation is part of the circumstances a court weighs.

Where a defect sits on a New York City sidewalk, the separate question of who owns the duty still has to be answered first. Our page on NYC sidewalk injury liability works through when the abutting building owner is responsible and when the City remains the defendant.

 

The Photographs and Measurements That Beat a Trivial Defect Motion

This doctrine is unusual in how directly it rewards evidence gathered in the first days. Nearly every factor a court weighs is visible, and nearly all of it disappears when the defect is repaired.

• A scale in the frame. A ruler, a tape, or a coin laid against the defect, photographed straight on and from the side. A photograph without a reference object proves the shape and nothing about the size.
• The side profile. Elevation and edge condition read from a low angle and are almost invisible from above, which is the angle most people shoot.
• The approach view. A photograph from where you were walking, at eye level, showing what the defect looked like to someone coming toward it. This is the image that carries the visibility argument.
• The same conditions. If the fall happened at 9 p.m. under a dead streetlight, a photograph at noon is the defendant's exhibit rather than yours.
• The surrounding context. Crowd, doorway, awning, bus stop, subway stair, whatever explains why a person could not look at the ground.
• Age evidence. Weathering, rounded edges, dirt packed into the crack, and vegetation growing through it all show how long the condition sat, which is the separate notice question the defense will raise next.
• The repair. If the owner patches the defect after the fall, photograph the patch. It rarely comes in as an admission, but it fixes the location beyond argument.

If the defect has already been repaired, the case is harder but not over. Prior street view imagery, 311 records, Department of Transportation violation history, and photographs taken by anyone else for any reason can all reconstruct the condition. That work should start immediately rather than after a motion arrives.

What a New York Trip and Fall Claim Is Worth

New York does not cap compensatory damages, so value tracks the injury and its consequences rather than a statutory ceiling. A small defect regularly produces a large injury, because a trip at walking pace sends a person down with no time to protect anything.

• Medical expenses. Surgery, hospitalization, imaging, therapy, and the future care your treating physicians project.
• Lost earnings and earning capacity. Time out of work, and the longer-term loss where the injury changes what you can do.
• Pain and suffering. Usually the largest component, valued by comparison to what New York appellate courts have sustained on similar injuries.
• Loss of enjoyment of life. What the injury took out of your daily life, independence, and activity.
• Future care and household help. Services you now have to pay someone else to perform.
• Loss of consortium. A spouse's separate claim.

Comparative fault is the defense's fallback once triviality fails, and New York's pure comparative negligence rule means a share of fault reduces recovery rather than ending it. Our pages on how pain and suffering is valued in New York and how comparative fault works cover both in detail.

Why This Question Should Not Be Answered From a Photo on Your Phone

People talk themselves out of real claims every week in this city because a defect looked small in a picture, or because someone on the phone told them it was.

An adjuster telling you a defect is too trivial to sue over is not giving you a legal opinion. Don't simply take their word for it. If you were seriously hurt we are going to take your case and investigate before reaching any conclusions. Half the time, the defect is only one piece of the case. The lighting, the slope, the surrounding surface, drainage, crowding, or the way the edge caught a shoe can be what turns a seemingly minor defect into a dangerous one.
