Augrented Insights Report for 138 Union Street

138 Union Street is a 4-story, 6-unit residential building constructed in 1931, currently owned by Dmitry Knopov. The most recent significant incident occurred in May 2024, when complaints about pests were filed and investigated by the Department of Housing Preservation and Development, though no violations were found.

The building has experienced several inspection-related events between 2021-2023, including tenant safety inspections, a building shaking complaint in January 2023, and multiple violations related to inadequate tenant protection plans during construction work in February 2021, with associated penalties that have since been resolved. Notably, there are currently two active violations from June 2023 regarding the failure to file 2018 and 2019 external low-pressure inspections.

The building's recent history shows consistent maintenance of bedbug management protocols, with annual reports since 2021 indicating zero infestation cases across all reporting periods. The property underwent multiple permitted work activities between 2020-2021, including electrical, plumbing, and other improvements, most of which were properly documented through official permits. While the building's overall violation history shows some concerning patterns in 2021 regarding tenant safety compliance during construction, it's worth noting that most recent complaints and inspections have not resulted in any violations being issued, suggesting improved compliance with housing regulations.
