Is NYC’s Unfinished Leaning Skyscraper Safe? Engineers Have Message

An unfinished skyscraper in New York City, known as One Seaport or Seaport Residences, located at 161 Maiden Lane in Manhattan’s Financial District, has drawn renewed scrutiny over its structural stability. The 670-foot tower, which has been left incomplete since 2019, has raised concerns among residents and experts alike, particularly after recent reports suggesting potential structural issues. While officials insist the building poses no immediate danger, ongoing legal disputes and unresolved regulatory violations continue to cast doubt on the project’s future. Work on One Seaport began in 2015, but progress halted around that time as initial surveys revealed the structure was leaning approximately three inches toward the north. This led to a dispute between the project’s contractor and developer, Fortis Property, with court documents citing that the lean caused the building to encroach on a neighboring property line. The situation escalated into litigation, highlighting the growing complexity surrounding the stalled development. In 2024, online platforms such as Reddit featured images claiming the building was leaning further westward and appearing to touch the adjacent structure. These claims fueled public anxiety, though they were not supported by official assessments. Earlier in 2017, a tragic incident occurred when a construction worker fell over two dozen floors after his safety harness failed and no protective measures were in place, underscoring the risks associated with the ongoing construction efforts. As of July 2026, the site remains under investigation by the New York City Department of Buildings (DOB), which has recorded six active violations. These include failure to address hazardous conditions, lack of proper documentation for completed work, and absence of a tenant protection plan. A DOB spokesperson confirmed that the project is subject to a Stop Work Order issued in 2021, following the withdrawal of the general contractor. The permit for the site has not been renewed since its expiration in 2020, further complicating the project’s status. Despite these ongoing issues, the DOB has stated that no evidence of structural instability or immediate public risk has been observed. Inspectors have conducted periodic visits to the site, finding it closed and free of unsafe conditions. The department emphasized that compliance with safety regulations is continuously monitored, and no recent notifications regarding unsafe structural conditions have been received. Engineers have weighed in on the controversy, offering reassurance that a leaning structure does not inherently pose a danger. Industrial engineer Jacob Ferguson noted that while public perception often equates a lean with instability, the reality is more nuanced. He stressed that engineers rely on continuous monitoring and data to assess a building’s condition, rather than visual observations alone. Key factors include whether the structure is still shifting, whether foundation settlement is ongoing, and whether the building is carrying its intended load. Structural engineer Greg Batista concurred, explaining that some buildings are intentionally designed with minor tolerances and can remain stable for extended periods despite visible movement. He emphasized that the presence of a lean does not automatically indicate a problem unless accompanied by signs of continued movement or changes in behavior. Both experts urged caution against drawing conclusions based solely on appearance, advocating instead for thorough technical evaluation. With the project remaining dormant and regulatory hurdles persisting, the fate of One Seaport remains uncertain. As the city continues to grapple with aging infrastructure and evolving safety standards, the case of this unfinished tower serves as a complex example of the challenges faced by urban development projects in a dynamic metropolitan environment.
