The city is suing the designer of a $41.5 million public library along Queens waterfront for failing to provide handicapped access.

City lawyers on Wednesday slapped architect Steven Holl and his firm with a lawsuit in Manhattan Supreme Court for failing to comply with the Americans with Disability Act while designing Hunters Point Library in Long Island City. The city is seeking at least $40 million in damages.

Following nearly a decade of project delays, the 22,000-square-foot library opened to great fanfare in September 2019. It drew raves from elected officials and architectural critics impressed by its sweeping Manhattan skyline views and its aluminum-painted concrete facade featuring sculpted cuts.

But within months, the 82-foot-high building overseen by Queens Public Library drew the ire of advocates and the federal government for allegedly violating the ADA and other laws by lacking wheelchair accessibility.

The library is plagued with construction flaws – including failing to provide elevator access to three-tiered fiction section, a rooftop garden and a reading space on the children’s floor that are all inaccessible for people who use wheelchairs, critics say.

As a temporary measure, books shelved on the inaccessible tiers were relocated to tables in other parts of the building near elevators.

The library is already the subject of a federal probe and a separate federal lawsuit filed by advocates against the city alleging disability discrimination. Both still are pending. 

Messages left with Holl and his Manhattan-based company, Steven Holl Architect, were not returned, but the company previously told Crain’s New York Business “there is no wrongdoing here.”

The city’s Law Department declined comment.
