Augrented Insights Report for 770 Jefferson Avenue

770 Jefferson Avenue is a 4-story, 8-unit residential building in Bedford-Stuyvesant, owned by Daniel Schwimmer and built in 1910. The property has experienced recurring maintenance issues over the past two years, with notable complaints regarding heating systems, plumbing problems, and safety concerns. Most recently, in May 2025, there were complaints about unsanitary sewage conditions and toilet plumbing issues, with the latter resulting in official violations.

During 2024, the building faced multiple heat and hot water outages, including one affecting the entire building in November 2024. Several emergency complaints were filed regarding doors, windows, flooring, and various plumbing issues, though some inspections could not gain access to the affected areas. The building's safety systems have required attention, with violations noted in August 2024 regarding missing smoke detectors and carbon monoxide detectors in Apartment 2R, as well as blocked fire escape egress due to flower pots on various floors. Multiple Housing Maintenance Code violations have been documented, including issues with shower drain pipes, floor conditions, and self-closing doors.

The property has an active Department of Buildings violation from September 2024 regarding failure to file external low-pressure inspections, with similar violations dating back to 2019 also remaining open. Rodent inspections show mixed results, with rat activity recorded in 2022 and 2025, but a passing result in May 2024. The bedbug report for the period of November 2022 to October 2023 shows no infestations in the building. Two illegal conversion complaints were filed in 2024, both resulting in inspectors being unable to gain access, and there were previous work without permit complaints in 2021 with similar access issues.
