in federal bonds to renovate the building. Restoration of the lobby revealed some of Gilbert's original terracotta work that had been covered over during an earlier modernization project. During this restoration, the copper roof was replaced for $4 million; the granite base was restored for $5 million; replacement gargoyles were added; and over 7,000 replica terracotta tiles were added. A parking garage was also built in the building's basement. The interior was converted into apartments and reopened in mid-2005 as 90 West Street, a 410-unit residential building. The next year, it received a National Preservation Honor Award from the National Trust for Historic Preservation. 90 West Street was listed on the National Register of Historic Places on January 25, 2007. The designation included the exterior and part of the interior. The building was slightly damaged in November 2007, when a large sewer pipe from the World Trade Center site burst open and flooded the basement, causing a two-week evacuation of the building. The operators of the National September 11 Memorial & Museum proposed in 2011 to use 90 West Street as a security screening site for museum visitors, which was controversial among the building's residents. Despite this, 90 West Street ended up being utilized as a visitors' center for people traveling to the memorial. During residential conversion, the building had received a 421-g tax exemption, meant for developers converting Lower Manhattan buildings to residential use, and as such, some of the residential units were rent-stabilized. Tenants of 90 West Street filed a lawsuit in the mid-2010s, stating that the building's owner, the Kibel Company, had wrongfully eliminated rent regulation for the building's residential units. In 2019, the New York Supreme Court ruled in the tenants' favor, since the owner had received benefits under the 421-g tax incentive program, and was thus bound to provide stabilized leases for the tenants. The next year, the New York Supreme Court ruled that Kibel only owed rent-stabilized tenants four years of back rent, instead of the six years provided in the Housing Stability and Tenant Protection Act of 2019. Critical reception Upon its opening, the West Street Building was lauded by other architects and artists. The architectural critic Montgomery Schuyler, in a 1919 Scribner's Magazine article, noted that the West Street Building was uncommon in that it was praised by both the public and by architectural critics.
