The four-story, 10-unit building at 23 West 129th Street in Harlem, owned by Lars Westvind, has experienced several significant maintenance issues over the past few years. Most notably, there were heating and hot water problems affecting the entire building in February 2022, though these were reportedly resolved within two days. In June 2020, there was an unsanitary condition complaint regarding pests, but inspectors were unable to gain access for verification. The building has also faced recurring issues with bedbug reporting compliance, receiving Class A violations in 2022, 2023, and most recently in April 2024, all related to failure to file annual bedbug reports as required under the Housing Maintenance Code. Furthermore, there is an active Department of Buildings violation from November 2019 concerning an unfiled 2017 boiler inspection report.
