Sidewalk Falls and Premises Liability in New York City

Sidewalk falls and premises liability in New York City

Authority: New York City Administrative Code § 7-210; General Municipal Law § 50-e; prior-written-notice statutes (e.g. NYC Admin. Code § 7-201(c)); Mastromarino v City of New York; Vucetovic v Epsom Downs, 10 NY3d 517.

Who is responsible for a New York City sidewalk is counter-intuitive, and getting it wrong at the start of a case is usually fatal, because the deadline for suing a municipality is far shorter than the deadline for suing a private owner.

Administrative Code § 7-210 shifted tort liability for a defective sidewalk from the City of New York to the owner of the abutting property. The owner must maintain the sidewalk in a reasonably safe condition and is liable for injuries caused by a failure to do so. For most of the city — commercial buildings, apartment buildings, mixed-use property — the defendant is the building owner, not the City.

There is one significant exception, and it swallows a large share of the outer boroughs. Section 7-210 does not apply to a one-, two- or three-family residential property that is both owner-occupied, in whole or in part, and used exclusively for residential purposes. Both conditions must be satisfied. For those properties liability stays with the City — which means a Notice of Claim within 90 days under General Municipal Law § 50-e, and suit within one year and 90 days.

So the first question in any sidewalk case is the character of the abutting building, because it determines who the defendant is, which clock applies, and whether a 90-day deadline has already been missed. Courts have treated the exception as turning on the building’s actual physical character and use rather than solely on the certificate of occupancy’s designation.

Where the City is the defendant, prior written notice usually applies

For the roadways and sidewalks it remains responsible for, the City is generally protected by a prior-written-notice requirement: it cannot be held liable for a street or sidewalk defect unless it had received written notice of that specific defect, or affirmatively created it through an act of negligence. Establishing notice — commonly through the Big Apple Pothole and Sidewalk Protection Corporation maps — is often the whole case.

Tree wells are not sidewalk

In Vucetovic v Epsom Downs the Court of Appeals held that § 7-210 does not impose liability on the abutting owner for a defect in a tree well. Defects in and around street trees are analysed separately from the flags of the sidewalk itself.

Snow and ice run on their own rules

An owner is not liable for a natural accumulation while a storm is in progress, and has a reasonable time after it ends to clear the walk. A defendant who clears negligently and creates or worsens a hazard — the classic refreeze from piled snow — loses that protection. Hour-by-hour certified climatological data is the evidence that decides these cases.

Out-of-possession landlords and tenants

A lease can shift the practical duty to maintain to a commercial tenant, but § 7-210 liability runs to the owner. The lease, any indemnity clause and the additional-insured endorsements determine who ultimately pays, which is why the full lease and every certificate of insurance belong in the first discovery demand.

Comparative fault still applies here

Premises cases remain under pure comparative fault: the May 2026 bar on recovery above 50% applies only to motor-vehicle actions under Insurance Law article 51. A sidewalk plaintiff found 70% at fault still recovers 30%.
