873 Union Street, Brooklyn, NY 11215

873 Union Street, a three-story, 8-unit residential building constructed in 1885 in Park Slope, is currently owned by Nicholas Kotsonis. The property has experienced several noteworthy incidents in recent years, with the most recent being a water supply-related plumbing issue in September 2023, which was promptly addressed and closed within eight days. The building has maintained a consistent record of bedbug control, with no reported infestations or eradications in any unit over the past four reporting periods from 2021 to 2025.

Compliance with rodent control measures appears to have improved since 2011, with a passed inspection in April 2011 following an initial failure the previous month. The building's violation history shows attention to inspection requirements, with records indicating a violation for failure to file the 2021 external low-pressure inspection report in June 2023, though this was subsequently dismissed in July 2023. There is one active Department of Buildings violation from January 2024, though specific details are not provided in the records.

An egress-related complaint was filed in October 2024 but was found to have no warrant for violation upon inspection. The property had multiple housing maintenance code violations in 2021 and 2022 related to bedbug reporting requirements, though these appear to have been resolved. While the building has experienced various maintenance issues over the years, the relatively recent nature of some violations, including plumbing issues and inspection-related matters, suggests ongoing maintenance requirements. However, the more recent absence of bedbug infestations, successful resolution of plumbing issues, and regular maintenance of safety inspections indicate active property management.
