Do you have to prove a Washington store knew about the spill before you fell?

By Michael Shemtoub, trial attorney, Beverly Law. Updated November 2026.

The starting rule: a store answers for what it knew or should have found

A shopper in a store is an invitee, and Washington measures the duty owed to invitees by Restatement (Second) of Torts § 343. The Washington Supreme Court applied §§ 343 and 343A in Iwai v. State (1996), a fall on ice in a state agency’s Spokane parking lot, and rejected the rule that owners owe nothing for naturally accumulated snow and ice.

Under § 343, an owner is liable to an invitee for a dangerous condition only if it:

• knew about the condition, or would have discovered it with reasonable care, and should have realized it posed an unreasonable risk;
• should have expected that customers would not see the danger or protect themselves from it; and
• failed to use reasonable care to protect them.

The first item is where the notice requirement comes from. In Ingersoll v. DeBartolo, Inc. (1994), a shopper slipped on a clear smear in a common area of the Tacoma Mall. The court said she had to show the owner had, or should have had, knowledge of the condition in time to fix it or warn her. She offered no such evidence, and the court affirmed dismissal of her case.

Match the hazard to what you have to prove

Washington cases sort store falls into a handful of patterns. What you must show depends on which one fits your fall.

When the way the store operates replaces proof of notice

In Pimentel v. Roundup Co. (1983), a precariously shelved paint can fell and injured a customer’s foot. The Washington Supreme Court held that notice need not be shown “when the nature of the proprietor’s business and his methods of operation are such that the existence of unsafe conditions on the premises is reasonably foreseeable.” The court refused to apply that rule automatically to every self-service store. The customer has to show that the particular operation made the unsafe condition foreseeable.

For years Washington courts tied the exception to self-service areas. A four-justice lead opinion in Iwai dropped that limit, but it did not draw a majority. The Washington Supreme Court settled the point in Johnson v. Liquor & Cannabis Board (2021). It was raining when a shopper stepped off the last entry mat of a state-run liquor store and fell on the floor just inside, and the clerk testified that rainy days always brought muddy footprints into the entryway. The court held that the reasonable foreseeability exception “applies outside the context of a self-service area of a business.”

Showing foreseeability does not end the case. The jury then decides whether the store took reasonable precautions. As Iwai summarized Wiltse v. Albertson’s Inc. (1991), a plaintiff can establish liability by showing the store failed to inspect as often as the foreseeable risk required.

Where the exception runs out

• The hazard must come from the store’s operations. In Wiltse, a shopper slipped in water coming through a hole in the roof of a self-service grocery store. The court held the exception did not apply, because a roof leak is not a danger created by self-service. The shopper had to prove notice.
• You need evidence, not a label. In Ingersoll, the court said self-service “is not the key to the exception.” The shopper lost because the record said nothing about how many food vendors the mall had, where they were in relation to the fall, how they operated, whether patrons carried food in from outside, or the history of prior falls.
• The hazard must be foreseeable in the spot where you fell. In Carlyle v. Safeway Stores, Inc. (1995), a shopper slipped on a quarter-sized spot of shampoo in the coffee aisle of a Walla Walla store. The shampoo was stocked several aisles away. Evidence that the produce area was slippery did not make shampoo in the coffee aisle foreseeable.
• A wet floor alone is not enough. Johnson repeated older case law that “something more than a slip and a fall is required” and that water on a store floor does not by itself establish negligence. Dropping the self-service limit, the court said, does not remove the need to prove an unreasonably dangerous condition.

The store records that decide the notice question

Most of the proof about notice sits with the store.

• The incident report and the first inspection. In Ingersoll, mall security found nothing on the floor, but the record did not show when the officer looked. Ask who checked the spot, when, and what they wrote down.
• Video. Footage from before the fall can show when a spill appeared and who walked past it. That goes straight to constructive notice. Ask the store in writing to keep it.
• Sweep and inspection logs. In Carlyle, the court said a store’s housekeeping practices bear on constructive notice, but the shopper had no evidence that the store’s inspection schedule was too thin for the risk in that aisle.
• Prior falls and complaints. The history of earlier slip and fall incidents was one of the gaps the court listed in Ingersoll.
• Weather and maintenance records. In Iwai, the fall was not reported until the following week, so the lot was never documented that day. The maintenance supervisor, deposed almost five years later, had no specific memory of conditions that month.

When a party controls relevant evidence and fails to produce it without a satisfactory explanation, Washington law lets the jury infer the evidence would have been unfavorable to that party. Henderson v. Tyrrell (1996) explains that rule from Pier 67, Inc. v. King County and weighs how important the missing evidence was and the fault of the party that lost it. The inference is not automatic. In Tavai v. Walmart Stores, Inc. (2013), the court refused it because the store’s cameras likely did not cover the spot where the shopper fell and nothing showed the video was deleted after she asked for it. The court would not require stores to keep all video every time someone falls and files a report. It did say that once a shopper files an accident report, the store must act in good faith about keeping direct video of the fall.

Your own share of fault and the three-year deadline

Stores often argue that the shopper should have been watching the floor. In Washington, that argument can reduce what you recover, but it does not bar the claim. Under RCW 4.22.005, any fault charged to you reduces the award in proportion. If a jury puts 25 percent of the fault on you, your damages go down by 25 percent.

The deadline to file a personal injury lawsuit is three years under RCW 4.16.080(2). For a notice case, the practical clock is shorter. As Iwai shows, memories of a single shift fade long before three years pass.

What this means for your case

1. Report the fall before you leave. Ask for the incident report number and the manager’s name.
2. Photograph the substance, its size, any cart tracks or footprints through it, the nearest display, the mats and any warning sign. Tracks and dried edges can help show how long it was there.
3. Write down the aisle or entrance, the time, the weather and the names of employees nearby.
4. Ask the store in writing to keep the video from before and after the fall, that day’s sweep and inspection logs and the incident file.
5. Get medical care and keep every record.
