A&F Williams Street LLC v. New York Power Authority ($3M+ Structural Damage Suit Over White Plains Garage Demolition)
A&F Williams Street LLC, owner of a five-story office building at 165 Main Street in White Plains, sued the New York Power Authority in Westchester County Supreme Court on September 15, 2026, alleging that vibration from NYPA's demolition of its adjacent parking garage cracked the building's roof parapet and detached its roofing membrane. The negligence-and-trespass suit seeks more than $3 million in damages and repair costs and asks the court to halt further demolition absent a reasonable access agreement.
Why it matters
Illustrates how a commercial owner's short-term access accommodation to a neighboring developer, public or private, can become the flashpoint for a structural-damage claim once demolition work exceeds what the access agreement contemplated. Owners near infrastructure or redevelopment projects, and the authorities and developers doing that work, should take note of how monitoring, notice, and access-agreement drafting bear on liability once damage actually occurs.
