The NY 'Storm in Progress' Doctrine: Suing for Snow and Ice Slips in New York

Current as of: September 15, 2026 Slip and Fall & Premises Liability New York
❄️
In New York, the "Storm in Progress" doctrine protects property owners from immediate lawsuits during active winter weather. Legally, landlords and business owners are granted a reasonable grace period to clear snow and ice after the precipitation has completely stopped.

A sudden slip and fall on ice can cause severe injuries, from shattered wrists to traumatic brain injuries. When this happens, victims naturally want to hold the property owner accountable. However, New York winters are notoriously harsh, and the state's legal system recognizes that it is impossible for a property owner to shovel continuously while a blizzard is actively raging. This is where the "Storm in Progress" doctrine comes into play. It suspends a property owner's duty to clear walkways until the storm ends. Defeating this legal defense requires gathering critical evidence fast. If you have been injured, finding a skilled personal injury attorney through our US Lawyer directory is the best way to determine if you have a viable claim.

Applicability Across New York State (NYC, Albany, Buffalo)

Whether you fall outside a bodega in Manhattan or a large retail store in Buffalo, the "Storm in Progress" defense is universally applied across New York. The success of your lawsuit often hinges on precise timing and weather data.

The Exact Timeline of the Legal Grace Period

The doctrine applies not just to massive blizzards, but also to freezing rain and sleet. Under New York common law, property owners are given a "reasonable amount of time" after the storm stops to remedy the hazard. However, local municipalities often have specific codes that define this timeline. For example, under N.Y.C. Admin. Code § 16-123, property owners must clear sidewalks within 4 hours after snow stops falling, provided it stops between 7:00 AM and 4:49 PM. If the snow stops overnight (between 9:00 PM and 6:59 AM), they have until 11:00 AM the following morning. Your lawyer will cross-reference the exact time of your fall with certified meteorological records from the National Climatic Data Center.

Commercial vs. Residential Properties

While the grace period applies to both, commercial property owners (like supermarkets, malls, and parking garages) are generally held to a stricter standard of vigilance once the storm ends. Commercial entities often have maintenance crews on staff, whereas residential homeowners may be at work during the day. However, if a commercial property owner attempts to clear the snow during the storm but does a poor job (for example, piling snow in a way that it melts and refreezes into a dangerous sheet of ice), they can lose the protection of the doctrine by actively creating a new hazard.

Exemptions for Out-of-State Landlords

Many New York properties are owned by out-of-state investors or absentee landlords. These landlords cannot use the excuse that they were "not in the state" to avoid liability. Under New York law, property owners have a non-delegable duty to maintain their premises in a reasonably safe condition. If an out-of-state landlord fails to hire a local property management company or snow removal service, they can still be sued in the New York County Supreme Court, New York for negligence.

How to Prove Pre-Existing Black Ice

The most common way defense attorneys use the doctrine is by claiming the ice you slipped on was created by the current storm. To win your case, your lawyer must prove you slipped on "pre-existing" ice-ice that was left over from a previous storm days earlier. This is often seen in cases like Solazzo v. New York City Transit Authority, 6 N.Y.3d 734 (NY Court of Appeals 2005). Proving pre-existing ice requires presenting photographs showing dirty, hardened, or thick ice layers (indicating age) versus fresh white snow. Witness testimonies and historical weather data proving that temperatures fluctuated, causing old snow piles to melt and freeze into black ice, are also critical.

How Much Does it Cost in New York?

  • Court Filing Fees: To initiate a lawsuit in a New York Supreme Court, you must purchase an Index Number ($210 under N.Y. C.P.L.R. § 8018(a)), plus a Request for Judicial Intervention fee ($95 under N.Y. C.P.L.R. § 8020(a)).
  • Meteorological Experts: Hiring a certified climatologist to analyze weather data and testify about when the storm ended can cost between $2,000 and $5,000.
  • Attorney Fees: Personal injury lawyers in New York work on a contingency fee basis. You pay nothing upfront. If you win your case, the attorney takes 33.3% (one-third) of the final settlement or jury award.

How Long Does the Process Take?

Slip and fall cases involving snow and ice are heavily defended by insurance companies. The discovery phase alone, which includes depositions and expert weather reports, can take 12 to 18 months. Depending on court backlogs in counties like Bronx or Kings (Brooklyn), a full resolution or trial can take anywhere from 2 to 4 years.

Can I sue if it was only lightly flurrying when I fell?

Yes, but it is difficult. Courts have ruled that even minor, ongoing precipitation like freezing rain or light flurries can invoke the Storm in Progress doctrine, protecting the owner until it completely stops.

What if the property owner shoveled, but I still fell?

If an owner volunteers to clear the snow during a storm, they must do so carefully. If their shoveling creates a more dangerous condition (like exposing slick ice underneath without applying salt), you may have grounds for a lawsuit.

Who do I sue if I slipped on a city sidewalk?

In many parts of New York, including NYC under N.Y.C. Admin. Code § 7-210, the legal liability for maintaining and clearing sidewalks falls on the abutting property owner, rather than the municipality, unless the property is an owner-occupied one-, two-, or three-family residential dwelling.

How quickly should I contact a lawyer?

Because weather evidence and ice melt rapidly, consulting an attorney promptly is critical. Legal counsel can act quickly to subpoena nearby surveillance footage before it is overwritten and preserve certified meteorological records for the exact date and time of the incident.
