721 Hart Street, Brooklyn, NY 11221
721 Hart Street is a 5-story, 32-unit residential building constructed in 2017, currently managed by SL Hart Holdings LLC. The building has experienced recurring maintenance issues over recent years, with the most recent concerns in 2025 involving radiator heating problems and wall paint issues, though inspections for these complaints were not completed.
Prior to this, there were multiple plumbing and maintenance complaints in 2024 that required attention, including issues with toilets, water leaks, and wall/ceiling repairs in Apartment 1B, some of which resulted in violations. The building's elevator service has been a persistent concern, with active complaints regarding single-device service dating back to at least 2019, and an active Environmental Control Board violation as of October 2024 regarding parking structure reporting requirements. The property has maintained reasonable pest control measures, with no bedbug infestations reported in the past four filing periods from 2020 through 2024.
Regular rodent inspections (April 2023 to April 2025) have consistently passed, indicating good overall building hygiene. While there were some significant maintenance issues early in the building's history, including a 2019 heat/hot water outage that was quickly resolved, the more recent years have shown a pattern of maintenance requests that often result in violations or require follow-up inspections. The building's management has generally addressed issues once they are formally documented through violations, though there are some current open violations regarding elevator service and parking structure reporting that remain unaddressed as of mid-2025.
