The 8-story, 24-unit building at 39 East 21st Street in Flatbush, owned by Jay Blausman and constructed in 2016, has experienced several significant maintenance issues between 2024 and 2025. The most recent concern involves a rat sighting reported in June 2025, following previous inspections in March 2024 and multiple instances between 2014-2022 showing rat activity. Between July and October 2024, the building faced multiple water-related issues, including slow leaks (both from September 2024) and a heavy flow incident in August 2024, along with several instances of mold problems, particularly in September 2024. Other maintenance issues have included a heating/hot water complaint for the entire building in July 2024, which inspectors were unable to access to verify, and various problems with ceilings and flooring that resulted in multiple housing code violations.
The building has also faced some regulatory compliance issues, as evidenced by violations recorded in October 2024, including a broken fire exit knob on the 7th story, improper carbon monoxide notice posting requirements, and several maintenance issues in apartment 6A related to paint and water leaks. An active elevator maintenance issue has been reported as of June 2025 regarding single-device operation with no alternate service. While the building was constructed relatively recently in 2016, it has experienced recurring problems with water leaks, mold, and rodent activity, though it has maintained a consistent record of zero bedbug infestations since 2019. The property was subject to two ECB violations in 2018 related to insulation and housekeeping, both of which were resolved with no penalties imposed.
