What is a "trivial defect," and can it end my trip and fall case?

When a fall is caused by a lifted sidewalk slab, a seam in a parking lot or a small lip at a doorway, the owner may answer that the defect was too small to matter. That argument has a name, the trivial defect rule, and it can end a claim before a jury ever hears it. It sits alongside the other questions on our slip, trip and fall injuries page, such as notice and your own care.

This guide explains what the rule says, who decides it, when it is raised in a lawsuit, and what evidence bears on it. For the wider rules on public and private hazards, see our dangerous conditions of property page.

How is a trivial defect argument decided, step by step?

1. The claim is presented. Against a city or county, a written claim is due within six months of the fall (Government Code 911.2). Against a private owner, a lawsuit generally must be filed within two years (Code of Civil Procedure 335.1).
2. The defense raises triviality. A defendant can ask the court to end the case through a motion for summary judgment, arguing there is no triable issue of fact (Code of Civil Procedure 437c).
3. Both sides submit evidence. Photos, measurements, declarations and deposition testimony go to the court in writing. Your opposition is due at least 20 days before the hearing (Code of Civil Procedure 437c(b)(2)).
4. The court views the evidence in your favor. For public property, the court must view the evidence "most favorably to the plaintiff" (Government Code 830.2).
5. The court asks one question. Was the risk so minor, trivial or insignificant, in view of the surrounding circumstances, that no reasonable person would conclude it created a substantial risk of injury to people using the property with due care?
6. The answer sends the case one way or the other. If yes, the condition is not dangerous as a matter of law and that claim ends. If reasonable people could disagree, the question goes to the jury, which is told that a condition creating only a minor risk is not a dangerous condition (CACI 1102).

What does the law actually say?

Government Code 830 defines a "dangerous condition" of public property as one that creates a substantial risk of injury, "as distinguished from a minor, trivial or insignificant" risk, when the property or adjacent property is used with due care in a reasonably foreseeable way. Government Code 830.2, unchanged since 1963, then allows the trial court or an appellate court to decide that question itself: a condition is not dangerous if the court determines, viewing the evidence most favorably to the plaintiff, that the risk was so minor, trivial or insignificant in view of the surrounding circumstances that no reasonable person would conclude it created a substantial risk of injury.

Three parts of that sentence matter in every case. The court must take your evidence at its strongest. The measure is the risk, judged "in view of the surrounding circumstances," not the defect's size alone. And the test is whether no reasonable person could see a substantial risk, not whether some people would shrug it off. The statute sets no height, depth or width. A decision the Judicial Council cites under CACI 1102 adds that whether a set of facts creates a dangerous condition is usually a question of fact, and may be decided as a matter of law only if reasonable minds can come to but one conclusion.

Does the rule apply to private property too?

Yes. A 2022 decision the Judicial Council cites under CACI 1001 says a property owner "is not liable for damages caused by a minor, trivial, or insignificant defect" on its property, and that people who maintain walkways, "whether public or private," are not required to keep them in absolutely perfect condition. A 2011 decision cited under CACI 1007 applied the same rule in a privately owned townhome development and noted that what counts as a minor defect may be a question of law. A decision cited under CACI 1102 states that the law imposes no duty on a landowner, "including a public entity," to repair trivial defects.

The practical result is the same on both sides: a defendant can argue that a small defect was not dangerous at all, which makes questions such as notice and inspection irrelevant. For those other questions, see our guide on how to prove the owner knew about the hazard.

What counts as the surrounding circumstances?

The statute does not list them, and no jury instruction does either. The words point beyond the ruler to the setting in which a careful person met the defect. Evidence that may bear on it includes the lighting at that hour, shadows from trees or buildings, leaves or debris hiding the edge, rain or glare, whether the colors of the two surfaces blended together, the shape of the edge (smooth or jagged), how many people use the route, and anything that would naturally draw a walker's eyes elsewhere, such as a store entrance, a crosswalk signal or traffic.

History can matter too. A decision cited under CACI 1102 says the absence of other similar accidents is relevant to whether a condition is dangerous, but is not decisive by itself. Earlier complaints or repair requests about the same spot can work in the other direction, and they also bear on notice under Government Code 835. For how a sidewalk claim is divided between a city and the owner next door, see who is responsible for a sidewalk trip and fall in Sonoma or Marin County.

When is the motion filed, and how much time is there to respond?

Much of the evidence in an opposition comes from sworn testimony. Our guide on preparing for a deposition in a premises case explains what that day looks like.

What changes the answer?

Poor lighting or a hidden edge. The same height difference can be judged differently at noon and at dusk, because the court weighs the risk "in view of the surrounding circumstances" (Government Code 830.2).

Your own care. Whether a condition is dangerous does not depend on whether you were careful. The last sentence of CACI 1102 says so, and a decision cited there adds that a plaintiff's lack of due care is relevant only to comparative fault. Any share of fault reduces damages under CACI 405.

Actual notice does not save a trivial defect. The 2022 decision cited under CACI 1001 says the duty of an owner, "even one with actual notice," does not require the repair of minor defects. Proving the city knew helps only once the defect is found to be more than trivial (Government Code 835).

The defect is on a stair or ramp. A violation of a building standard that caused the kind of harm it was meant to prevent creates a presumption of negligence (Evidence Code 669); see whether a building code violation can prove a stair fall case.

The hazard was easy to see. Obviousness is a separate argument from triviality, with its own rules (CACI 1004). Read whether you can recover when the hazard was obvious or marked with a sign.

A public road or park. The same definition of a dangerous condition applies to every kind of public property (Government Code 830); our guide on what makes public property legally dangerous covers roads, parks and buildings.

What could this look like? An example

For example, imagine a woman walking along a downtown Petaluma sidewalk just after sunset. A slab lifted by a tree root catches her toe, and she falls and breaks her kneecap. The next morning her son photographs the spot with a tape measure showing a lift of a little under one inch, then takes pictures from 10 and 30 feet away showing the tree's shadow, a pile of leaves along the edge, and a shop entrance across the street. A neighbor tells them she reported the slab to the City the year before.

Within six months, she presents a written claim to the City (Government Code 911.2). After the City rejects it, she sues, and the City moves for summary judgment, arguing the lift was trivial. Her opposition, filed at least 20 days before the hearing, includes the photos, the measurements, the neighbor's declaration and a description of the light at that hour. The court must view that evidence most favorably to her and decide whether reasonable people could see a substantial risk. If they could, the dangerous-condition question goes to a jury; if not, her claim against the City ends. This example is made up to show how the rules fit together; it says nothing about any real case.

What mistakes make the trivial defect rule harder to answer?

• Taking only a close-up photo of the crack, with no measurement and nothing showing the setting.
• Waiting to photograph the spot until it has been ground down, patched or replaced.
• Not returning at the same time of day to record the lighting and shadows.
• Failing to ask neighbors or nearby businesses whether anyone reported the spot.
• Treating the owner's "it was only half an inch" as the end of the matter, when the statute sets no height.

What should I do this week?

1. Measure the height difference with a tape measure or ruler held upright against the edge, and photograph it.
2. Photograph the spot from several distances and from the direction you were walking.
3. Go back at the same time of day and record the light, shadows and anything covering the edge.
4. Write down what you were looking at and why, such as a doorway, a signal or traffic.
5. Ask neighbors whether they reported the defect, and keep their names and numbers.
6. Find out who owns the spot and mark the six-month date; our guide on how to file an injury claim against a city or county lists where Sonoma and Marin claims go.
7. Check the local courts and claim offices on our Sonoma County personal injury guide. For a fall in that city, see our Petaluma page.

Frequently asked questions

Is there a height under which a defect is always trivial?

No. Government Code 830.2 sets no measurement. The court weighs the risk in view of the surrounding circumstances, viewing the evidence most favorably to the injured person.

Can a judge decide this instead of a jury?

Yes, but only when no reasonable person could see a substantial risk. A decision cited under CACI 1102 says the question is usually one of fact and may be decided as a matter of law only if reasonable minds can come to but one conclusion.

If the judge rules against me, is that the end?

It ends that claim in the trial court. Government Code 830.2 refers to both "the trial or appellate court," so the question can also be reviewed on appeal.

Does it help that other people tripped there?

It can. A decision cited under CACI 1102 treats the absence of earlier accidents as relevant but not decisive, so earlier falls or complaints are part of the picture the court sees.

Where would my case be heard?

In the superior court of the county where the fall happened. For a fall here, our guide to what to expect at Sonoma County Superior Court explains the steps after filing.

How long do I have?

Six months for a written claim against a public entity and generally two years for a lawsuit against a private owner. See California personal injury deadlines for the details and exceptions.
