AI summary · updated June 2026

The 8-unit, 4-story residential building at 54 Martense Street in Flatbush, owned by Gil Shenhav and constructed in 1930, has experienced several significant maintenance issues over recent years. The property faced multiple heating and hot water system problems in both December 2019 and January 2020, with emergency complaints regarding both apartment-specific and building-wide systems. These incidents occurred alongside various other maintenance issues including plumbing problems and door/window repairs, all of which were eventually closed out. More recently, the building has received four consecutive annual Housing Maintenance Code violations (2021-2024) for failing to file the required annual bedbug report, and in 2020, there were multiple Class C violations specifically related to Apartment 1 that required repairs to doors, hot water systems, and various structural elements including floor and baseboard issues.

Inspection and complaint records from the Department of Buildings show activity between 2020 and 2025, including a 2021 construction safety compliance issue and an illegal hotel room complaint in 2025, though the latter was closed due to inspector access issues. Multiple permits were issued in 2020 for various types of work, suggesting some maintenance and improvement efforts were being undertaken during this period. While many historical complaints and violations have been resolved, as of 2025, there remain open bedbug reporting violations from previous years and some structural/maintenance issues requiring attention, particularly regarding the building's heating systems which have been a recurring problem throughout its recent history.
