Oregon Slip and Fall Laws: Proving Premises Liability Under Comparative Fault

To win a slip and fall claim in Oregon, you must prove the property owner failed to exercise reasonable care to discover and remedy or warn of an unreasonably dangerous condition, that the owner had notice of the hazard, and that the failure caused your injury. Oregon uses modified comparative negligence with a 51% bar under ORS 31.600.

Proving a slip and fall claim in Oregon

Oregon slip and fall cases are governed by general premises liability law rooted in the duty of reasonable care. There is no single comprehensive Premises Liability Act in Oregon equivalent to Colorado's PLA; instead, the standards emerge from common law principles refined through cases like Woolston v. Wells, 297 Or. 548, 687 P.2d 144 (1984), and codified comparative-fault rules under ORS 31.600.

Your right to recover turns on your status as a visitor. An invitee (a customer, store visitor, or member of the public invited onto land held open for a business or public purpose) is owed the highest duty: the owner must use reasonable care to discover unreasonably dangerous conditions and either repair them or warn about them. A licensee (a social guest, for example) is generally owed a duty regarding known dangers. A trespasser is typically owed only a duty not to be willfully or wantonly harmed.

Notice is central to most invitee claims. You must show the owner either had actual notice of the hazard (an employee created it, a report was made) or constructive notice (the condition existed long enough that a reasonable inspection would have uncovered it). Courts look to inspection logs, surveillance footage, maintenance records, and witness testimony to establish what the owner knew and when.

The open-and-obvious doctrine in Oregon

Oregon does not allow property owners to escape liability simply because a hazard was visible. In Woolston v. Wells, 297 Or. 548 (1984), the Oregon Supreme Court held that the Restatement (Second) of Torts sections 343 and 343A(1) "known or obvious danger" formulation is no longer correct Oregon law following the legislative adoption of comparative fault and the abolition of implied assumption of the risk. Instructing a jury that a possessor is not liable for a danger known or obvious to the invitee improperly imports contributory-negligence concepts and frustrates the comparative-fault system.

This is a significant protection for Oregon slip and fall victims. The obvious nature of a hazard does not erase the landowner's duty to protect invitees from unreasonably dangerous conditions. Instead, under ORS 31.600, the jury considers the obviousness of the hazard when apportioning fault percentages between the plaintiff and the defendant. If you were partly at fault for not avoiding an obvious hazard, your damages are reduced proportionally. But unless your fault exceeds 50%, you can still recover. A property owner cannot simply point to a wet floor sign or a clearly visible ice patch and walk away from liability.

Ice, snow, and natural accumulation in Oregon

Oregon has not adopted the "natural accumulation rule" that exists in states like Illinois or Ohio, which generally immunizes landowners from liability for falls on naturally accumulated ice and snow. Oregon takes a different approach: an ordinary reasonable-care duty applies.

Under the framework established in Woolston v. Wells, 297 Or. 548 (1984), a possessor of land owes invitees a duty to discover and remedy or warn of unreasonably dangerous conditions, and this includes ice and snow accumulations. Foreseeability and the obviousness of the icy condition factor into the comparative-fault analysis rather than creating a categorical bar to liability. A landlord whose parking lot consistently develops black ice after rain, a retailer whose entry mat soaks up snow and creates a slipping hazard, or a homeowner whose front walkway is left uncleared for days after a snowstorm can all face liability under an ordinary-care standard.

Beyond private landowner duties, many Oregon municipalities compound this responsibility. Portland, for example, imposes sidewalk snow and ice-clearing ordinances on the owners of abutting properties. Violating a local ordinance can be evidence of negligence in a civil lawsuit. There is no blanket no-duty rule for natural accumulations in Oregon.

How fault is shared: Oregon's negligence rule

Oregon follows modified comparative negligence with a 51% bar under ORS 31.600. This statute codifies the rule that a claimant may recover only if their fault "was not greater than the combined fault" of all defendants, third parties, and settling persons. Equal fault (50% plaintiff / 50% defendant) still allows recovery; the plaintiff is barred only when their fault is greater than the combined fault of others, meaning 51% or more.

In practical terms: if a jury finds your total damages to be $100,000 but assigns you 30% of the fault, you recover $70,000. If the jury assigns you 50% fault, you still recover $50,000. If the jury assigns you 51% or more, you recover nothing. Oregon's "not greater than" language (modified-51) is more favorable to plaintiffs than the modified-50 variant used in Colorado, because a 50/50 split still allows recovery in Oregon.

Insurance defense attorneys routinely argue that if you saw or should have seen the hazard, your fault percentage should be elevated. The higher your assigned fault, the more your recovery shrinks. This is why documenting how the hazard appeared, how long it had been present, and what warnings (if any) were posted matters from the moment of the fall.

Deadlines: statute of limitations and government claims

Two separate deadlines govern Oregon slip and fall cases. Missing either one can permanently end your claim.

Personal-injury statute of limitations: Under ORS 12.110(1), you have 2 years to commence an action for personal injury "not arising on contract." Oregon applies a discovery rule: the clock begins when the injury was or reasonably should have been discovered, which in most fall cases is the day of the incident. Minors generally have the period tolled until age 18. For more on Oregon's civil filing deadlines, see the Oregon statute of limitations.

Government notice of claim: If your fall occurred on state or local government property (a public sidewalk, a government building, a municipal park), the Oregon Tort Claims Act (ORS 30.275(2)(b)) requires formal written notice of claim within 180 days after the alleged loss or injury. This is a strict prerequisite to suing a public body; failure to give timely notice bars the claim entirely. The 180-day notice deadline is far shorter than the 2-year lawsuit deadline. If you slipped on a public sidewalk in Portland, in a state office building, or in a city-owned facility, contact an attorney immediately to preserve your government claim.

What an Oregon slip and fall claim is worth

The value of a slip and fall settlement or verdict in Oregon depends on several interconnected factors.

Economic damages cover all actual financial losses: emergency and hospital care, surgery, rehabilitation, future medical treatment, lost wages, lost earning capacity, and out-of-pocket costs like medical equipment or home modifications. Oregon does not cap economic damages.

Non-economic damages cover pain and suffering, emotional distress, loss of enjoyment of life, and similar intangible harms. Oregon does not impose a general statutory cap on non-economic damages in most personal-injury cases, meaning there is no ceiling on pain-and-suffering recovery in a standard slip and fall lawsuit.

Comparative-fault reduction: Whatever total damages a jury awards are reduced by your percentage of fault under ORS 31.600. If you are assigned 20% fault on a $100,000 verdict, you receive $80,000. At 50% fault you receive $50,000. At 51% or more you receive nothing.
