Idaho Slip and Fall Laws: Proving Premises Liability

To win a slip and fall claim in Idaho, you must prove that the property owner was negligent, that the owner had actual or constructive notice of the hazard, and that the hazard caused your injury. Idaho applies modified comparative negligence, meaning your own percentage of fault reduces your recovery and bars it entirely if you are 50% or more at fault.

Proving a slip and fall claim in Idaho

Every Idaho slip and fall case rests on basic premises liability principles. In Idaho, the duty a property owner or occupier owes still depends on the status of the person who was hurt: invitee, licensee (social guest), or trespasser (Brooks v. Wal-Mart Stores, Inc., 164 Idaho 22, 27 (2018)). Most slip and fall claimants are invitees, such as a customer in a store or a visitor to a business open to the public. After Harrison v. Taylor, 115 Idaho 588, 768 P.2d 1321 (1989), an owner or occupier owes invitees a duty of ordinary care under the circumstances.

You must show that a dangerous condition existed and that the owner had notice of it. Notice can be actual (the owner knew about the hazard) or constructive (the condition existed long enough that a reasonable owner exercising due diligence would have discovered and corrected it). A puddle that forms from a roof leak reported to management is a classic example of actual notice; a spill that sat on a grocery store floor for 45 minutes before a fall raises constructive-notice questions for the jury.

Causation ties the negligence to your injury. You must show that the hazardous condition was a proximate cause of your fall and that the fall caused your documented losses. Medical records, incident reports, witness statements, and photographs taken at the scene are the foundation of any Idaho premises liability case.

The open-and-obvious doctrine in Idaho

Many states allow property owners to escape liability entirely when a hazard was open and obvious. Idaho does not. In Harrison v. Taylor, 115 Idaho 588, 768 P.2d 1321 (1989), the Idaho Supreme Court retired the open-and-obvious danger rule as a duty-negating bar, departing from its earlier Otts v. Brough line of cases. The court held that "owners and occupiers of land will be under a duty of ordinary care under the circumstances towards invitees who come upon their premises." Harrison did not abolish Idaho's entrant-status categories, and Idaho courts still key the duty owed to whether the visitor was an invitee, a licensee, or a trespasser.

Under Idaho law today, a landowner owes invitees a duty of ordinary care under the circumstances regardless of how visible a hazard may be. If a dangerous condition is open and obvious, that fact does not automatically defeat your claim. Instead, it is one factor the jury considers when comparing the relative fault of both parties under Idaho Code section 6-801.

For plaintiffs, this is a meaningful protection. Even if you walked toward a clearly visible obstacle or condition, the owner may still be liable if it was unreasonable to allow the hazard to persist. The jury will weigh the owner's negligence against your own, and fault will be apportioned accordingly. Obviousness can reduce your recovery by increasing your share of comparative fault, but it will not bar the claim outright.

Ice, snow, and natural accumulation in Idaho

Some states apply a "natural accumulation" rule that exempts property owners from liability for falls caused by naturally occurring ice and snow, reasoning that these are conditions everyone faces and that owners cannot be expected to eliminate all winter hazards. Harrison v. Taylor, Idaho's leading case on the duty owed to invitees, did not decide whether Idaho follows that rule.

Harrison v. Taylor (1989), a case about a fall at a hole in a sidewalk, established a general duty of ordinary care under the circumstances toward invitees; the opinion did not decide whether that duty reaches naturally accumulated snow and ice. Under Harrison's ordinary-care standard, whether a property owner acted reasonably and whether the injured invitee was comparatively negligent will normally be jury questions, unless reasonable minds could not differ.

If you fell on a naturally icy parking lot, a snow-covered sidewalk, or a pathway that had not been treated after a storm, Harrison alone does not answer whether the owner can rely on a natural-accumulation defense, so have an Idaho attorney review the case law that applies to your fall.

How fault is shared: Idaho's negligence rule

Idaho follows modified comparative negligence with a 50% bar, codified at Idaho Code section 6-801. Under this system, your damages are reduced in proportion to your own percentage of fault. If a jury finds you 20% at fault and the property owner 80% at fault, you recover 80% of your total damages.

The 50% bar is the key threshold. Because the statute says recovery is available only if your negligence "was not as great as" the defendant's, being equally at fault (50/50) counts as your fault being "as great as" the defendant's and therefore bars recovery entirely. This is different from a modified-51% rule (used in some states), where a plaintiff at exactly 50% fault can still recover. In Idaho, 50% fault is the cutoff, not 51%.

Practical implications: if you were distracted by your phone, wore unsafe footwear in known icy conditions, or ignored posted warnings, a jury may assign you a share of fault. Your attorney's job is to keep that number below 50% by showing that the owner's failure to maintain the property was the primary cause of the fall.

Idaho does not cap economic damages (medical bills, lost wages, future care costs), so a significant injury with high economic losses can still produce substantial compensation even with some comparative fault. The non-economic cap discussed below applies separately to pain and suffering.

Deadlines: statute of limitations and government claims

Personal-injury statute of limitations: In Idaho you have 2 years from the date of your injury to file a slip and fall lawsuit in court (Idaho Code section 5-219(4)). There is no general discovery rule. The statute provides that the claim accrues "as of the time of the occurrence, act or omission complained of," and it extends discovery-based accrual only to foreign objects left in the body during professional malpractice and to fraudulent concealment by someone in a professional or commercial relationship with the injured party. In an ordinary slip and fall, the clock starts the day you fell, even if you did not appreciate how serious the injury was until later.

If the injured person was a minor when the fall happened, Idaho Code section 5-230 tolls the deadline during minority, but that same section caps disability tolling at six years. A child hurt at age 5 does not get until age 20 to sue: the tolling runs out six years later, and the 2-year period runs from there. The six-year ceiling bites for any child injured before roughly age 12, so a parent or guardian should not assume the claim can wait until the child is an adult.

Missing the 2-year deadline almost always results in dismissal of your case, regardless of how clear the liability is. The clock started the day you fell, so if two years are getting close, get a free consultation with an Idaho injury lawyer and get the lawsuit filed before they run out (attorney advertising).

Government notice-of-claim requirement: If you fell on property owned or controlled by a state agency, a city, a county, a school district, or another governmental entity, the Idaho Tort Claims Act imposes a separate, earlier requirement. You must file a written notice of claim with the relevant government entity before you can sue. For claims against political subdivisions (cities, counties, districts), the notice must be filed with the clerk or secretary within 180 days from the date the claim arose or was reasonably discovered (Idaho Code section 6-906). For claims against the State of Idaho or state employees, the notice goes to the secretary of state within the same 180-day window (Idaho Code section 6-905). Idaho Code section 6-908 makes this a strict, mandatory condition precedent: no claim or action is allowed unless the notice was timely filed.

The 180-day notice deadline can run out well before the 2-year lawsuit deadline. If you fell in a public building, on a city sidewalk, in a state park, or on any government-owned premises, treat the notice-of-claim requirement as your first and most urgent deadline.

What an Idaho slip and fall claim is worth

The value of an Idaho slip and fall claim depends on your economic damages, your non-economic damages, any reduction for your comparative fault, and whether the non-economic cap applies.

Economic damages include all out-of-pocket losses: medical bills (ER, surgery, physical therapy, future care), lost wages during recovery, lost earning capacity if the injury affects your long-term work ability, and related expenses. Idaho does not cap economic damages, so serious injuries with substantial medical costs can produce large economic awards.

Non-economic damages cover pain and suffering, emotional distress, loss of enjoyment of life, and similar intangible harms. Idaho Code section 6-1603 caps these at $538,425.04 for the period beginning July 1, 2026 (per the Idaho Industrial Commission's annual wage-adjustment calculation, a 5.78% increase over the prior year's $509,013.28), up from a 2003 statutory base of $250,000. The cap does not apply when the defendant's conduct was reckless, willful, or constituted a felony, so egregious property-owner behavior can expose defendants to higher awards. Because the cap adjusts again every July 1, you should confirm the current figure with an Idaho attorney.

Comparative fault reduction: If the jury assigns you 25% of the fault, your total damages award (economic plus non-economic) is reduced by 25%. If you are found 50% or more at fault, you recover nothing.

Frequently Asked Questions

How do I prove a slip and fall in Idaho?

You must show four things: (1) the property owner owed you a duty of reasonable care; (2) a dangerous condition existed on the property; (3) the owner had actual or constructive notice of the hazard; and (4) the hazard caused your fall and your injuries. Evidence typically includes photographs of the scene, incident reports, medical records, witness statements, and maintenance logs that establish how long the hazard existed.

Is Idaho an open-and-obvious state?

No. Idaho abolished the open-and-obvious doctrine as a complete bar to recovery in Harrison v. Taylor (1989). An obvious hazard does not automatically defeat your claim. Instead, under Idaho Code section 6-801, obviousness is one factor the jury weighs when comparing the fault of both parties. The property owner can still be liable for a visible hazard if it was unreasonable to leave it unaddressed.

Can I sue for falling on ice in Idaho?

Possibly, but the leading case does not settle it. Harrison v. Taylor (1989) established a general duty of ordinary care under the circumstances toward invitees, but that case involved a hole in a sidewalk and did not decide whether the duty reaches naturally accumulated ice and snow. Under Harrison, whether an owner acted reasonably and whether the injured invitee was comparatively negligent will normally be jury questions, unless reasonable minds could not differ. Have an Idaho attorney review the case law that applies to your fall.

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

Two years from the date of injury under Idaho Code section 5-219(4). If you were hurt on government property, you must also file a written notice of claim within 180 days under the Idaho Tort Claims Act (Idaho Code sections 6-905 and 6-906). The notice-of-claim deadline often expires first, so treat it as the more urgent requirement if any government entity was involved.

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

Yes, as long as your fault is less than 50%. Idaho Code section 6-801 uses modified comparative negligence with a 50% bar. Your damages are reduced by your percentage of fault. If a jury finds you 30% at fault, you keep 70% of the award. But if you are found 50% or more at fault, you recover nothing.

How much is an Idaho slip and fall claim worth?

It depends on your economic damages (medical bills, lost wages, future care), your non-economic damages (pain and suffering), any comparative fault reduction, and whether the non-economic cap applies. Idaho caps non-economic damages at $538,425.04 for the period beginning July 1, 2026 under Idaho Code section 6-1603, a figure that adjusts every July 1. Economic damages are uncapped. Use the Idaho slip and fall settlement calculator to estimate ranges for different injury severities and fault allocations.

What happens if I fell on city or state property in Idaho?

You must file a written notice of claim with the government entity within 180 days of the fall before you can file a lawsuit. For falls involving a city, county, or school district, file with the entity's clerk or secretary (Idaho Code section 6-906). For falls involving the State of Idaho, file with the secretary of state (Idaho Code section 6-905). Missing this deadline bars the suit entirely, even if the 2-year lawsuit deadline has not yet run.
