Ice and Snow Slip and Fall Accidents: Property Owner Liability in PA, NJ, NY, and MD

Winter weather across the Mid-Atlantic creates treacherous conditions that lead to thousands of slip and fall injuries every year. Icy parking lots, snow-covered sidewalks, frozen steps, and black ice on walkways are responsible for fractures, traumatic brain injuries, and spinal cord damage that can change lives permanently. But when a property owner fails to address these winter hazards, they may be held legally accountable for the resulting injuries.

However, ice and snow cases are among the most legally complex premises liability claims because each state applies different rules about when property owners are and are not responsible for winter weather conditions.

Pennsylvania: The Hills and Ridges Doctrine

Pennsylvania applies a unique legal standard to winter slip and fall cases known as the “hills and ridges” doctrine. Under this rule, a property owner is generally not liable for injuries caused by ice and snow that result from natural weather events unless the accumulation has formed into hills and ridges that create an unreasonably dangerous condition. The rationale is that during and immediately after a snowstorm, it is impractical to expect property owners to keep surfaces completely clear.

To recover under this doctrine, you must typically show that the snow and ice had accumulated into ridges or elevations of a dangerous nature, a reasonable time had elapsed since the end of the storm for the property owner to address the condition, and the property owner failed to take reasonable steps to make the area safe. However, the hills and ridges doctrine has important exceptions. It does not protect property owners who caused an unnatural accumulation — such as a downspout that directs water onto a walkway where it refreezes, a roof without gutters that creates an ice sheet below the drip line, or a parking lot with improper drainage that pools water that then freezes. Additionally, localized patches of ice in areas where the property owner has cleared some but not all snow may not be protected by the doctrine.

New Jersey: Reasonable Care Standard

New Jersey does not follow the hills and ridges doctrine. Instead, it applies a general “reasonable care” standard to winter weather conditions. Commercial property owners — including stores, restaurants, office buildings, and apartment complexes — must take reasonable steps to remove ice and snow from walkways, entrances, and parking areas within a reasonable time after the storm ends.

What constitutes “reasonable” depends on the circumstances: the severity of the storm, the time elapsed since the snow stopped, the type of property, and the volume of foot traffic expected. A major shopping center is held to a higher standard than a small residential landlord. New Jersey also applies its comparative negligence rule — your compensation is reduced by your percentage of fault, and if you are more than 50% at fault, you cannot recover. Courts may consider whether you were wearing appropriate footwear, whether you chose a path you knew was icy when a safer alternative existed, and whether you were paying attention to where you were walking.

New York: Strict Property Owner Obligations

New York imposes significant obligations on property owners regarding snow and ice removal. Many municipalities, including New York City, have local ordinances requiring property owners to clear sidewalks within a specified number of hours after a snowfall ends — typically four hours during daytime hours. Failure to comply with these ordinances can be strong evidence of negligence.

New York also recognizes the “storm in progress” rule: property owners generally are not required to remove snow and ice while a storm is still actively occurring. However, once the storm ends, the duty to clear and treat surfaces begins. New York’s pure comparative negligence standard means that even if you were partially at fault — for example, if you saw ice and chose to walk over it — you can still recover damages, though your award will be reduced by your percentage of fault.

Maryland: Contributory Negligence Creates Higher Stakes

Maryland is one of only a handful of states that still follows the contributory negligence rule, which makes winter slip and fall cases particularly challenging. Under contributory negligence, if you are found even 1% at fault for your injuries — for example, if you knew the walkway was icy but chose to walk on it anyway — you may be completely barred from recovering any compensation.

This strict standard makes evidence preservation and legal strategy even more critical in Maryland ice and snow cases. Your attorney must demonstrate that the property owner bore full responsibility for the dangerous condition and that you took all reasonable precautions. Evidence that you were wearing appropriate footwear, that no alternative path was available, and that the ice was not visible (such as black ice) can help overcome a contributory negligence defense.

Common Winter Hazards That Lead to Lawsuits

The most dangerous winter hazards go beyond simple snow accumulation. Black ice — a thin, nearly invisible layer of ice that forms when temperatures drop — is especially treacherous and accounts for a disproportionate number of serious fall injuries. Refrozen meltwater in areas where snow was partially cleared but water was allowed to pool and refreeze creates unexpected ice patches. Inadequate salting or de-icing treatment — applying too little salt, using the wrong product, or applying it too late — leaves surfaces dangerously slick. Snow-covered ice creates a false sense of security, as a layer of snow may conceal solid ice underneath. Roof and gutter failures that cause icicles to fall or ice dams to direct water onto walkways create localized hazards the property owner should anticipate and prevent.

Evidence Is Critical — and Time-Sensitive

Winter slip and fall cases present unique evidence challenges because the hazardous condition — ice and snow — is inherently temporary. By the time you consult an attorney, the ice may have melted and the snow may have been cleared. This makes immediate evidence collection essential. Photograph the exact spot where you fell, including close-ups of the ice or snow condition. Note the time and temperature at the time of your fall. Check whether the property had been salted or treated (look for salt residue). Document whether other walkways or areas had been cleared while the area where you fell was neglected. Identify surveillance cameras that may have captured the conditions. Get contact information from any witnesses. Check local weather records for the storm timeline — when it started, when it ended, and how much time elapsed before your fall.

Frequently Asked Questions

Can I sue if I slipped on ice during a snowstorm?

Generally, property owners are not required to remove snow and ice while a storm is actively occurring (the “storm in progress” rule). However, if the dangerous condition was caused by a pre-existing problem — such as a drainage issue that created ice before the storm, or a failure to treat surfaces before a predicted storm — the property owner may still be liable. Once the storm ends, the duty to clear and treat surfaces begins.

How long does a property owner have to remove snow after a storm?

There is no single answer — it depends on the state, municipality, and type of property. Some municipalities have specific ordinances (New York City generally requires sidewalk clearing within four hours of a snowfall ending). Absent a specific ordinance, the standard is “reasonable time,” which courts evaluate based on the severity of the storm, the resources available to the property owner, and the foot traffic expected on the property.

What is black ice and why is it so dangerous in slip and fall cases?

Black ice is a thin, transparent layer of ice that forms on surfaces like pavement, making it nearly impossible to see. It typically forms when temperatures drop rapidly after rain or melting snow, often during overnight hours or in shaded areas. It is particularly dangerous because victims cannot see and avoid it, which also strengthens legal claims — the “open and obvious” defense does not apply when the hazard is invisible.

Does Pennsylvania’s hills and ridges doctrine mean I can never sue for ice injuries?

No. The hills and ridges doctrine has significant exceptions. Property owners can still be held liable for unnatural accumulations of ice (caused by drainage problems, downspouts, roof runoff, etc.), conditions created by the property owner’s own actions, localized patches in areas that were otherwise cleared, and ice that forms from sources other than general precipitation. An experienced Pennsylvania premises liability attorney can evaluate whether an exception applies to your case.
