The developer of a sagging Midtown Manhattan skyscraper has been accused of carrying out unauthorized construction after two columns buckled and several floors collapsed.

The owner of the the 37-story office building on East 42nd Street performed construction that went beyond previously approved plans, according to a complaint filed by the New York City Department of Buildings (DOB) on Tuesday.

Specifics of the complaint against the owner, listed as 235 Fee Owner LLC, are not yet publicly available but the DOB’s portal stated that ‘no support of excavation has been approved.’

Construction crews evacuated the skyscraper just after 8am Tuesday after they discovered that two columns had begun to buckle.

The 21st to 26th floors of the building near Grand Central Terminal caved in under stress, officials say. Multiple cracks and sagging floors have been reported throughout the high-rise.

Footage filmed by workers showed the massive silver beams on the 21st and 22nd floors buckling and bending just moments before the floor started to crumble.

The building remains unstable, but experts insist that any collapse would be localized and that, due to its steel supports, the high-rise won’t come toppling down.

The skyscraper, which once housed pharmaceutical giant Pfizer, has been under renovation since 2024 and is being converted into a 1,500-unit luxury apartment complex.

The DOB has issued 22 violations at the address, dating back to 2022, according to the agency’s public portal. A majority of the violations stemmed from failing to file elevator inspection and testing reports.

Thirteen complaints remain active, with 235 Fee Owner LLC owing the city $39,000 in penalties.
