Emergency crews evacuated a Midtown Manhattan city block on Tuesday, July 7, 2026, after structural columns buckled inside a 37-story construction site at 235 East 42nd Street. Mayor Zohran Mamdani confirmed the building remains unstable, prompting the closure of surrounding streets and the evacuation of nearby buildings, including a school housing 400 children.
Structural Failure and Ongoing Risks
The situation at the former Pfizer headquarters—currently undergoing a conversion into luxury apartments—began just before 8 a.m. when construction workers reported structural issues. According to WABC, workers discovered that support columns on the 21st and 22nd floors had begun to buckle, causing the 21st to 26th floors to start caving under the stress. By Tuesday afternoon, officials reported that the building continued to shift, complicating efforts to stabilize the structure.
Fire Department Chief John Esposito emphasized the gravity of the scene, noting that the steel frame is suffering from significant stress. “It is not yet stable; it is still a very serious and dangerous situation,” Esposito said, via 6abc. While there are fears of a collapse, officials clarified that the building’s steel-frame construction makes a total collapse unlikely. Instead, authorities are monitoring for a potential localized failure.
The Department of Buildings (DOB) is monitoring the building's movement from the outside.
History of Violations at the Construction Site
City records reveal that the project at 235 East 42nd Street has been the subject of multiple safety complaints and fines in recent months. As reported by the New York Daily News, the site has incurred more than $30,000 in penalties over the past year. Violations include failure to report a worker injury in December 2025, unsafe demolition practices, and debris falling onto the sidewalk from the 33rd floor.

Union representatives pointed to the scale of the renovation as a primary concern. Cliff Johnsen of the Steamfitters Local 638 stated that the addition of 11 floors to the existing structure placed extreme pressure on the original supports. “The I-beams are bending like cigarettes in there, which is super dangerous,” Johnsen told the New York Post.
The conversion of aging office buildings into residential towers is a complex engineering feat. Because older office buildings often have different floor-to-ceiling height requirements and structural load capacities than residential buildings, developers frequently must reinforce existing steel frames. When these projects involve vertical expansions—adding new floors atop an existing structure—the foundational stress increases significantly.
Evacuations and the “Frozen Zone”
The city established a “frozen zone” spanning 40th to 45th streets between First and Third avenues, shutting down both pedestrian and vehicular traffic. Among the buildings evacuated were the Hampton Inn Manhattan Grand Central, the Kennedy International School, and the Israeli Consulate.
Mayor Mamdani stated that no injuries have been reported and all construction personnel were safely evacuated. The Department of Buildings is currently using highly sensitive equipment to measure the smallest of movements, with plans to deploy emergency trusses to shore up the affected floors once the structure is deemed safe enough for engineers to enter.
Project Scope and Future Outlook
The site is being developed by Metro Loft and David Werner Real Estate. The conversion is slated to create 1,602 apartments. A spokesperson for Metro Loft said the company is working closely with the Department of Buildings to address the situation, emphasizing that worker and public safety remain their top priority.
Large-scale construction projects in dense urban corridors are subject to strict oversight by the Department of Buildings.
The long-term stability of the tower remains under investigation. City officials have not yet provided a timeline for when the surrounding streets will reopen or when displaced residents and workers will be permitted to return to the area.
