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. Woolston involved a fall on a staircase, not ice or snow; the court held that the obviousness of a hazard is something the jury weighs in determining and comparing fault rather than a categorical bar to liability.

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. For a fall on a Portland sidewalk or in a state or city building, ask an Oregon injury lawyer for a free consultation on giving the written notice within 180 days (attorney advertising).

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. In a claim against a private property owner, 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, so in a suit against a private owner there is generally no ceiling on pain-and-suffering recovery.

Public-body defendants are capped. If the property owner is a state or local government body, the Oregon Tort Claims Act limits your total recovery no matter how large your proven losses are. ORS 30.271 provides that the liability of the state "to any single claimant" for such claims "may not exceed" the statutory limit, which began at $2 million per claimant and $4 million for all claimants for causes of action arising on or after July 1, 2014. ORS 30.272 sets much lower limits for a local public body such as a city or county, starting at $666,700 per claimant and $1,333,300 for all claimants on the same basis. Both sets of figures are adjusted annually by the State Court Administrator, by no more than 3% in any year, so confirm the current adjusted limit for the year your claim arose. The cap applies to economic and non-economic damages together, and under ORS 30.269 punitive damages may not be awarded at all on a claim subject to the Tort Claims Act. This is the same category of defendant that triggers the 180-day notice described above, so a fall on a public sidewalk, in a state office building, or in a city-owned facility carries both the short deadline and the damages ceiling.

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.

Frequently Asked Questions

How do I prove a slip and fall in Oregon?

You must show that you were an invitee (or licensee), that an unreasonably dangerous condition existed on the property, that the owner had actual or constructive notice of the hazard, that the owner failed to exercise reasonable care to fix or warn about it, and that this failure caused your injury. Constructive notice is established by showing the hazard existed long enough that a reasonable inspection would have found it.

Is Oregon an open-and-obvious state?

No. Oregon abolished the open-and-obvious defense in Woolston v. Wells, 297 Or. 548 (1984). The Oregon Supreme Court held that treating an obvious hazard as a complete bar to liability contradicts the state's comparative-fault system. In Oregon, the obviousness of a hazard is only a factor in apportioning fault, not a threshold bar to recovery.

Can I sue for falling on ice in Oregon?

Yes. Oregon has no natural-accumulation immunity rule. Property owners owe invitees an ordinary reasonable-care duty that extends to ice and snow hazards they knew or should have known about. Many Oregon cities also impose ordinances requiring property owners to clear sidewalks of ice and snow. Violating such an ordinance can serve as evidence of negligence.

How long do I have to file a slip and fall lawsuit in Oregon?

Two years from the date of injury (or date of discovery) under ORS 12.110(1). If your fall occurred on government property, you must also give written tort-claim notice to the public body within 180 days of the injury under ORS 30.275(2)(b). Missing the 180-day government notice deadline permanently bars your claim against that public body, regardless of the 2-year lawsuit period.

Can I recover damages if I was partly at fault for my fall?

Yes, as long as your fault is 50% or less. Oregon uses modified comparative negligence with a 51% bar (ORS 31.600). If you are 50% or less at fault, you recover your damages reduced by your fault percentage. If your fault is greater than 50% (i.e., 51% or more), you recover nothing. A 50/50 split still allows recovery in Oregon.

How much is an Oregon slip and fall claim worth?

It depends on your economic losses (medical bills, lost wages), non-economic losses (pain and suffering), and your percentage of fault. In a claim against a private property owner, Oregon does not cap economic or non-economic damages in most personal-injury cases, so there is no statutory ceiling on what a jury can award. If the defendant is a state or local public body, the Oregon Tort Claims Act does cap the total recovery: ORS 30.271 and ORS 30.272 set annually adjusted per-claimant limits that apply to economic and non-economic damages combined. Your total award is then reduced by your share of comparative fault under ORS 31.600.

What is the Oregon Tort Claims Act and how does it affect my case?

The Oregon Tort Claims Act (ORS 30.275) governs suits against state and local government entities. If you were injured on public property, you must give the government entity written notice of your claim within 180 days of the injury. This short deadline runs concurrently with (not after) the 2-year personal-injury statute of limitations. Failing to give timely notice bars the claim against the government defendant entirely. The Act also limits what you can collect: ORS 30.271 and ORS 30.272 cap the total liability of state and local public bodies to a single claimant, and ORS 30.269 bars punitive damages on claims subject to the Act.
