852 Union Street, Brooklyn, NY 11215
The two-story, six-unit residential building at 852 Union Street in Park Slope, constructed in 1902 and currently owned by Nicholas Kotsonis, has experienced several notable events in recent years related to both maintenance and pest control.
Most recently, in September 2023, there were plumbing and water supply issues reported through both 311 and Housing Maintenance Code complaints, though these were investigated by the Department of Housing Preservation and Development and closed without any violations being issued. The building has come under scrutiny for bedbug reporting compliance, receiving violations in both March 2022 and April 2021 for failing to file the required annual bedbug reports as per Housing Maintenance Code regulations.
However, since that time, the property has consistently reported zero infestations in its subsequent filings, including the most recent report from June 2025 covering the period from November 2023 to October 2024. The building's bedbug reporting history shows a clean record, with no infested or re-infested dwelling units reported in any of the annual filings since 2021, suggesting that the management has successfully addressed this particular issue since the violations were issued.
