On July 7, a 37-storey building at 235 East 42nd Street in Midtown Manhattan, formerly Pfizer's headquarters, showed severe structural damage including two buckled steel columns and sagging floors on its 21st floor during conversion to residential apartments [1, 2, 3]. Authorities evacuated the building, nearby structures, and a school, and closed streets around Grand Central Terminal temporarily to ensure public safety [1, 3, 4].
No injuries were reported as all construction workers and occupants were safely evacuated [1, 3, 4]. Fire Department Chief John Esposito said the steel box beams had started to bend and deflect, creating "a very serious situation" that posed a risk of a localized, but not total, collapse [3]. Mayor Zohran Mamdani called it "an extremely serious situation," noting the building remained unstable and was still moving as of the afternoon of July 7 [1, 3].
The building, located between Second and Third Avenues just a block from the Chrysler Building, is a steel-frame structure built in the 1970s that is being converted into approximately 1,600 rental units, including 400 affordable homes — one of the largest office-to-residential conversions in New York City [1, 2, 5]. It had seven Department of Buildings violations and fines totaling over $32,000 from July to December 2025 [4].
Emergency crews installed shoring and steel supports overnight on July 7 to stabilize the building while fire department drones assessed the damage with technical visuals [3, 5, 6]. Streets initially closed from East 40th to 45th between First and Third Avenues were partially reopened by July 8 after stabilization showed no further movement [5, 6]. The New York City Department of Buildings Commissioner Ahmed Tigani said, "We have been able to bring in a plan and materials to stabilise the impacted floor..." [5].
Metro Loft Management and David Werner Real Estate Investments, the developers overseeing the conversion, said safety remained their top priority and expressed relief that no one was hurt [3]. The city continues to monitor the site closely as it proceeds with the stabilization and investigation.
The immediate next step is ongoing safety monitoring and structural assessments. Partial reopening of some streets and nearby buildings started on July 8, but evacuation orders remain in place for certain areas until authorities confirm the building’s full stability [5, 6].
