Real estate executive Jack Rosen is taking his Upper East Side neighbors to court, claiming a fuel-oil leak from their condo tower seeped into the ground around his townhouse and left a multimillion-dollar mess.
Rosen, the chairman of Rosen Partners, filed a complaint this week in Manhattan civil court seeking $40 million in damages. He alleges that a failed section of piping connected to a building tank at a neighboring tower triggered a leak during a January 2025 fuel delivery, soaking the soil by his property. According to the filing, the condo board then refused to allow a full environmental assessment or undertake remediation of the site.
As reported by The Real Deal, the suit claims the spill occurred on Jan. 13, 2025, following a delivery from Approved Oil and that piping on an above-ground storage tank failed. The complaint names the condominium at 30 East 85th Street, property manager Wallack Management and Approved Oil Company of Brooklyn as defendants. It also alleges that the New York State Department of Environmental Conservation added the incident to its public spill database on Jan. 28, 2025.
Navigation Law Shapes the Claim
Rosen’s attorneys are anchoring the case in New York’s Navigation Law, specifically Navigation Law §181. That provision makes “any person who has discharged petroleum” strictly liable for cleanup and damages, giving the statute real teeth in oil spill disputes.
The law authorizes the Department of Environmental Conservation to oversee removal efforts and allows injured parties to bring direct claims to recover remediation costs. With that framework in play, the courtroom fight is expected to center on who controlled the tank system, what testing and maintenance were performed and whether required inspections were properly documented.
Rosen’s Damages and the Timeline
The complaint alleges that oil migrated into the soil at Rosen’s property at 18 East 85th Street and that the condo board declined to grant his environmental consultants access to determine the full extent of the contamination. The suit seeks $40 million under the Navigation Law’s damage provisions, covering cleanup, property damage and related losses.
Although the spill is alleged to date back to January 2025, Rosen’s filing targets what he characterizes as months of inaction by the neighboring condo association, according to The Real Deal.
Who the Defendants Are
The defendants include both the building’s managing agent and its fuel supplier, each with longstanding New York footprints. Approved Oil describes itself as a family-owned energy provider serving the five boroughs, while Wallack Management highlights a decades-long track record managing luxury co-ops and condominiums.
Those public profiles set the stage for a high-stakes dispute, but it will be the court record that determines whether these companies, along with the condo board, are on the hook for the alleged contamination.
What to Watch
The case is likely to hinge on expert reports and paperwork detailing tank maintenance, piping protections and compliance with state-mandated testing and recordkeeping. Under the Navigation Law’s strict-liability structure, questions about who exercised control over the tank system and how the parties interacted with the DEC will be key.
For residents and condo boards across the Upper East Side, the suit serves as a reminder that older, on-site fuel systems can carry significant environmental and financial risk when something goes wrong underground.
