Eight million people walk on New York City’s 12,000+ miles of sidewalk every day. The sidewalks aren’t always safe. In fiscal year 2023, the NYC Comptroller’s Annual Claims Report recorded 2,134 sidewalk personal injury claims against the city alone, with $61.7 million in payouts. That figure doesn’t include the far larger number of claims filed against private property owners. Tree roots heave concrete slabs. Freeze-thaw cycles crack flagstones. Property owners neglect repairs for years. Snow and ice accumulate on uncleared walkways.
When someone trips on a raised sidewalk flag, slips on an icy patch, or falls into an uncovered cellar door, the question is always the same. Who pays?
The answer changed fundamentally in 2003. Here’s how NYC sidewalk liability works, who’s responsible, and what you need to prove.
The 2003 Shift: Administrative Code 7-210
Before September 14, 2003, New York City bore primary responsibility for maintaining sidewalks. If you tripped on a broken sidewalk, your claim was against the city. The city’s defense was almost always the same: prior written notice. If no one had reported the specific defect to the city before your injury, the city walked.
NYC Administrative Code § 7-210 changed everything. The law shifted liability from the city to the property owner adjacent to the sidewalk. Property owners of land abutting a sidewalk are responsible for installing, constructing, repaving, repairing, and replacing the sidewalk, including the curb. If a person is injured because of a failure to maintain the sidewalk, the property owner is liable.
The practical effect: if you trip on a broken sidewalk in front of a commercial building, an apartment complex, or a multi-family residential property, your claim is against the building owner, not the city.
Who Is Liable Under 7-210
Property Owners (Liable)
The following property owners bear sidewalk liability:
- Commercial property owners. Stores, restaurants, office buildings, warehouses. The adjacent sidewalk is their responsibility.
- Multi-family residential buildings (4+ units). Apartment buildings, co-ops, and condominiums with four or more units.
- Mixed-use buildings. Any building with a commercial component.
- Vacant lots and construction sites. The owner of the underlying property remains liable for the adjacent sidewalk.
The liability is non-delegable. In Xiang Fu He v. Troon Management, Inc. (2019), the New York Court of Appeals unanimously held imposes a non-delegable duty. A property owner can’t escape responsibility by hiring a management company or a snow removal contractor. If the contractor fails to clear ice and someone falls, the property owner is still liable. The owner can seek reimbursement from the contractor. But the injured person sues the owner.
Owner-Occupied Homes (Exempt)
One-to-three family residential properties that are owner-occupied are exempt from 7-210. If you trip on the sidewalk in front of a single-family house where the owner lives, the city retains liability under the prior written notice framework.
The exemption exists because the city council determined it would be unfair to impose absolute sidewalk liability on individual homeowners. The result: homeowners still have a moral obligation to maintain their sidewalks. But a legal claim against them requires proving negligence, not the strict liability standard that applies to commercial and multi-family property owners.
The City (Limited Liability)
The city retains direct responsibility for sidewalks it controls:
- Sidewalks adjacent to city-owned property (public buildings, fire stations, police precincts)
- Sidewalks in and around public parks (NYC Parks Department)
- Sidewalks along highways and overpasses (NYC DOT)
- Sidewalks where the city created the defect (utility work, road construction)
- Sidewalks where the city made a “special use” (installing infrastructure, bus shelters, bike racks)
Claims against the city for these sidewalks require a Notice of Claim within 90 days under . They also require proof the city had prior written notice of the defect.
Prior Written Notice: The City’s Shield
When the city is the defendant, the prior written notice doctrine is the most common defense. To hold the city liable, you must prove one of the following:
-
Someone reported the specific defect to the city before your injury. A 311 complaint, a DOT sidewalk repair request, a community board notification, or a letter to the borough commissioner’s office. The notice must identify the specific location and the specific condition.
-
The city created the defect. If a city construction crew broke the sidewalk during utility work and failed to repair it, prior written notice isn’t required. The city created the hazard and is liable.
-
The city made a special use of the sidewalk. Installing a tree pit, a bus shelter foundation, or other infrastructure that altered the sidewalk’s condition creates liability without prior written notice.
The prior written notice requirement has been criticized as an unfair barrier. The city maintains over 12,700 miles of sidewalk. Defects are everywhere. But unless someone formally reported the specific broken slab or raised flag before the injury, the city walks away.
NYC DOT inspects sidewalks on a rotating basis. Property owners receive violation notices for defects. Those DOT inspection records can sometimes serve as evidence of prior written notice.
Snow and Ice: Administrative Code 16-123
Snow and ice removal is governed by a separate provision. NYC Administrative Code § 16-123 requires property owners (including owner-occupied homes) to clear snow, ice, and dirt from the sidewalk within a specified time after a snowfall ends:
- Residential properties: Snow must be cleared within 4 hours after the snow stops, or by 11:00 AM if the snow stopped between 9:00 PM and 7:00 AM.
- Commercial properties: Same timeframe, plus the sidewalk must be kept clear during business hours.
- Width: A path at least 4 feet wide must be cleared. At bus stops, the full bus stop area must be cleared.
Failure to clear snow and ice within these timeframes creates liability for any injuries that result. The injured person must prove the property owner had a reasonable opportunity to clear the snow or ice before the fall.
Storm-in-progress doctrine: property owners aren’t generally liable for injuries that occur during an active storm. The obligation to clear begins after the storm ends. Once the storm ends, the clock starts running.
Common Sidewalk Defects
The defects that produce the most injury claims in NYC:
Raised sidewalk flags
Tree roots are the primary cause. As street trees grow, their root systems can exert up to 1,000 pounds per square inch, pushing concrete slabs upward. A height differential of as little as half an inch constitutes a defect under NYC DOT standards. NYC Parks receives over 9,000 requests per year for sidewalk inspections related to tree damage.
Broken or crumbling concrete
Age, weather, and heavy vehicle traffic (delivery trucks driving onto sidewalks) deteriorate concrete over time. Chunks break off, holes form, and the surface becomes uneven.
Missing or broken cellar doors
Many NYC buildings have cellar access through sidewalk-level doors. When the doors are left open, improperly secured, or deteriorated, they create fall hazards. Cellar door injuries can be severe because the fall is into a below-grade space.
Metal grates and utility covers
Con Edison access panels, subway grates, and water main covers can become slippery when wet. They can shift under foot traffic or develop gaps between the cover and the surrounding concrete.
Construction debris and scaffolding
Active construction sites create temporary sidewalk hazards: uneven plywood walkways, mud, debris, and reduced visibility under scaffolding. The general contractor and property owner share liability for pedestrian safety during construction.
What This Means for Injured Pedestrians
If you were injured on a NYC sidewalk, the first question is who owned the adjacent property. That determines who you sue and what you need to prove.
Private property owner (commercial or 4+ unit residential)
File a personal injury lawsuit within 3 years. Prove the sidewalk was defective and the owner failed to maintain it. You don’t need to prove prior notice under 7-210. Liability is essentially strict. The owner had a duty to maintain the sidewalk, the sidewalk was defective, and you were injured.
Owner-occupied 1-3 family home
The city retains liability. File a Notice of Claim within 90 days. Prove prior written notice of the defect.
City-maintained sidewalk
File a Notice of Claim within 90 days under . Prove the city had prior written notice, or that the city created the defect or made a special use.
Snow and ice
Determine whether the storm-in-progress doctrine applies. If the storm had ended and the property owner had a reasonable opportunity to clear the sidewalk, liability attaches.
Document the defect immediately. Photographs of the specific condition that caused the fall, the location, the surrounding area, and your injuries. NYC sidewalks change. Construction crews repair defects. Property owners pour new concrete. The evidence can disappear within days.
We’ve handled slip and fall cases across all five boroughs for over 35 years. We know how to identify the responsible property owner, obtain city inspection records, and prove the defect existed before the injury.
