252 Jefferson Street, Brooklyn, NY 11237

252 Jefferson Street is a six-unit, three-story Old Law Tenement building located in Bushwick, built in 1931 and currently owned by Serlin Building LP. The property has experienced recurring rodent issues, with the most recent rat sighting reported in January 2025 leading to Health Department violations that require follow-up inspections.

The building's maintenance history reveals significant heating and water issues in 2018, particularly affecting the first-floor apartment (1A), where violations included inadequate hot water supply, insufficient heating, and water leaks in the kitchen ceiling, though most of these violations were eventually resolved by early 2019. The summer of 2020 saw two complaints about building shaking and possible structural stability concerns, but inspectors were unable to gain access to investigate.

The building's pest control record shows consistent monitoring for bedbugs from 2020 to present, with official reports showing zero infested units in each annual filing period, suggesting effective management of this particular issue. The property has undergone regular rodent inspections from 2023 through mid-2025, with several showing "Rat Activity" and others passing, indicating ongoing challenges with pest management. The combination of recent health department violations, persistent rodent activity, and historical maintenance issues suggests some ongoing challenges with building upkeep and pest control, though there have been improvements in certain areas, such as the complete absence of bedbug infestations in recent years.
