Recent 311 calls from 2019-2022 primarily involved sidewalk maintenance and general street cleaning issues, with a notable ongoing sidewalk defect reported in February 2022. The building's systems have been updated over time, including plumbing improvements such as steam boiler replacement in 2012, and electrical work for foundation support in 2011.
