Augrented Insights Report for 1231 51st Street

The 4-story, 12-unit residential building at 1231 51st Street in Borough Park, owned by Eli Feldman and constructed in 1931, has experienced ongoing maintenance challenges in recent years, particularly in 2024. Most notably, there have been multiple pest-related complaints and violations, including three HPD complaints about unsanitary conditions due to pests in July 2024, and a bedbug infestation reported in 2022-2023 involving 8 units.

The building has also faced several plumbing issues, including problems with a bathtub/shower in June 2024, and emergency plumbing issues involving toilets reported in August 2024. Additional concerns include a lack of heat/hot water complaint in November 2023, with repeated access issues preventing inspection. The building's maintenance history reveals recurring structural and safety issues, including violations for broken or defective self-closing doors at the building entrance, and various interior maintenance needs in apartment 15 such as defective plaster and ceramic tiles.

The property has documented multiple ECB violations between 2018-2021 regarding occupancy and Certificate of Occupancy (CO) issues, with penalties totaling $50,000 related to unauthorized occupancy as a synagogue. More recent regulatory concerns include active DOB violations as of 2023 for failure to file external low-pressure inspection reports from 2017-2018. The building's bedbug reporting pattern shows some periods of infestation (most significantly in 2022-2023 with 8 units affected) but recent filings in 2024 indicate no current infestations.
