Slip and Fall on Snow and Ice in Illinois: The Natural-Accumulation Rule

You fell on ice and got hurt. Can you hold the property owner responsible? Sometimes. Illinois has one of the most defendant-friendly rules in the country, but it is not absolute.

By Lincoln Square Law · 7-minute read

A fall on ice is one of the most common winter injuries in Chicago, and one of the most misunderstood legally. People reasonably assume that a property owner who leaves a walkway icy is responsible for what happens next. Illinois law starts from nearly the opposite assumption. Whether you have a claim usually turns on a single question: where did the ice come from? The answer decides which rule applies, which defenses the owner can use, and what evidence you need to gather before the next thaw erases it.

The starting point: the natural accumulation rule

Illinois follows the natural accumulation rule. A property owner or possessor generally has no duty to remove snow and ice that accumulate naturally from weather, and is not liable for injuries caused by a natural accumulation. The Illinois Supreme Court reaffirmed the rule in Krywin v. Chicago Transit Authority, 238 Ill. 2d 215 (2010), holding that it applied even to a common carrier that otherwise owes its passengers a high degree of care. The reasoning is practical: in a climate like ours, requiring owners to keep every surface free of snow and ice at all times would impose an impossible burden.

Snow that falls, melts in the afternoon, and refreezes overnight is still a natural accumulation. So is ice that forms from ordinary weather on an untreated surface. A fall on that kind of ice, however painful, usually does not support a claim against the owner.

Where liability begins: unnatural accumulations

The rule protects owners from the weather. It does not protect them from conditions they create. An owner can be liable when ice forms or collects because of something the owner did or failed to maintain, sometimes called an unnatural or aggravated accumulation. Common examples include:

• A downspout or gutter that discharges water across a walkway, where it freezes.
• A roof, awning, or canopy that drips onto a path of travel in a predictable place.
• Grading, drainage, or pavement defects that channel melt into a low spot at an entrance.
• Plowing or shoveling that piles snow where it melts across a walkway and refreezes, or that leaves a compacted ridge in a path people must use.

The injured person carries the burden of showing that the ice was unnatural and that the owner knew or should have known about the condition. That is a factual showing, and it depends on evidence that is easy to lose: where the water came from, what the drainage looked like, whether the same patch formed repeatedly, and whether anyone had complained about it.

The Snow and Ice Removal Act

For residential property, the legislature added another layer. The Snow and Ice Removal Act provides that an owner, lessor, occupant, or other person in charge of a residential property is not liable for injuries allegedly caused by the snowy or icy condition of a sidewalk abutting the property that result from that person’s efforts to remove snow or ice, unless the conduct was willful or wanton (745 ILCS 75). The statute’s purpose is to encourage residents to shovel their sidewalks without fear that an imperfect job will lead to a lawsuit.

The Act is narrower than it first appears. In Murphy-Hylton v. Lieberman Management Services, Inc., 2016 IL 120394, the plaintiff fell on ice that she alleged formed because of defective drainage, not because of anyone’s snow removal efforts. The Illinois Supreme Court held that the Act’s immunity did not apply to an injury arising from negligent maintenance of the premises that was unrelated to snow removal. In other words, the Act protects the shovel, not the broken downspout. Commercial properties are outside the Act altogether, and their liability is analyzed under the common law rules above and any contractual duties.

Contracts, leases, and snow removal companies

Many commercial buildings, condominium associations, and apartment complexes hire snow removal contractors or assign snow duties in leases. Those documents matter. A contractor that negligently performs the work it agreed to do may be responsible for an unnatural accumulation it creates, and a lease or management agreement may shift responsibility among the owner, a tenant, and a manager. Identifying every party with a role in clearing or maintaining the area is part of the early investigation, and the contracts should be requested before positions harden.

Public property

Falls on city sidewalks, park district property, and other public land raise additional issues. The Local Governmental and Governmental Employees Tort Immunity Act provides that a local public entity is not liable for an injury caused by the effect of weather conditions as such on the use of streets, highways, alleys, sidewalks, or other public ways (745 ILCS 10/3-105). The same statute generally requires suit against a local public entity within one year (745 ILCS 10/8-101(a)). Claims involving CTA property carry their own notice and filing requirements under the Metropolitan Transit Authority Act (70 ILCS 3605/41). A fall on public property should be reviewed quickly, because the shorter clock and the immunities together leave little room for delay.

The Chicago sidewalk ordinance

Chicago requires owners and occupants to clear snow and ice from the public sidewalks abutting their property (Chicago Municipal Code §10-8-180). People often assume that a violation of the ordinance automatically makes the owner liable for a fall. It does not. The natural accumulation rule and, for residential property, the Snow and Ice Removal Act still shape whether a claim exists. The ordinance can be part of the picture, but it is rarely the whole answer.

Evidence that decides these cases

Winter evidence is perishable by nature. Within a day or two, the ice may be gone, salted, or covered by new snow. The most useful steps are taken immediately:

• Photograph the exact spot, the surrounding area, and the source of any water: downspouts, gutters, rooflines, drains, and slopes. Take wide shots and close-ups, and return to photograph the same spot in daylight if the fall happened at night.
• Note the weather: when it last snowed, the temperatures before the fall, and whether it had been melting. Historical weather records can confirm this later, but your own notes anchor the timeline.
• Keep the footwear you were wearing and do not clean it.
• Get names and contact information for witnesses and anyone from the property who responded, and ask whether an incident report was made.
• Seek medical care promptly and describe how the fall happened, so the record ties the injury to the location.

Later, a lawyer may request maintenance records, prior complaints, snow removal logs, contracts, and photographs or video from the property. Evidence that the same patch of ice formed repeatedly in the same place can be especially important, because it speaks to both the unnatural source and the owner’s notice.

Deadlines

The general limitations period for a personal injury claim in Illinois is two years from the injury (735 ILCS 5/13-202). Falls on public property may require suit within one year, and CTA claims have their own requirements. Because the evidence fades within days and the deadlines can be short, the most important step after a serious fall is to document the scene and get the facts reviewed early.

An honest assessment

Many falls on ice do not support a claim, and a good lawyer will tell you so. The ones that do usually share a pattern: ice that formed from a man-made source, an owner who knew or should have known, and evidence captured before the weather changed. If your fall fits that pattern, it is worth a careful look.
