The 6-unit, 3-story building at 257 Hart Street in Bedford-Stuyvesant, owned by Mark Berkowitz and constructed in 1931, has experienced several recurring maintenance issues over recent years. The property has active violations for failing to file required external low-pressure inspections from 2020 through 2023, with a special inspector's surrender of filing privileges in 2022 leading to a stop-work order. Recent inspection records from 2024 show multiple ventilation system, mold, and door-related complaints, as well as a rat sighting and garbage storage issues. Specific problems have been documented in Apartment 3B, including mold, water leaks, and ceiling repair needs, with some inspections reportedly unable to gain access for verification. Although there have been recent rodent inspections in 2025 and late 2024 that passed, there were also periods of rat activity noted between 2023-2024. The building's maintenance history shows various violations related to smoke detector requirements, gas leak procedures, and other housing maintenance codes, though many past violations have been resolved.
The property has maintained an active bedbug reporting record from 2020 through 2024, showing no reported infestations during these periods. Numerous complaints and violations were documented between 2018 to 2024 regarding work permits and construction-related issues, including work performed under stop-work orders and inadequate housekeeping conditions. The building's recent history (2023-2024) shows consistent maintenance needs, particularly regarding water systems and ventilation, with multiple complaints that either could not be verified during inspections or were marked as needing follow-up inspections.
