Augrented Insights Report for 850 East 31st Street

The 71-unit, 6-story building at 850 East 31st Street in Flatlands, owned by Roberta Koeppel, has experienced several notable maintenance issues between 2022 and 2025. Most concerning are recent water-related problems, with multiple plumbing complaints in May 2025 involving basins, sinks, and toilets, some of which resulted in violations. The building has also faced recurring heating system challenges, with active and past complaints about inadequate heat and hot water service between March and April 2025.

The property has a documented history of elevator service interruptions, with multiple complaints about single elevator service between 2019 and 2023, though inspections generally found no violations warranting further action. Recent inspections and complaints from 2024-2025 indicate various maintenance issues requiring attention, including unsanitary conditions (such as garbage storage), and multiple plumbing problems. Three apartments (B1, B9, D6) received multiple violations in December 2024 requiring repairs to various features including floors, cabinets, faucets, and safety devices like smoke and carbon monoxide detectors.

Notably, there was one Class A violation regarding lead paint hazards in apartment B1. The building has maintained a clean record concerning pest problems, with no reported bedbug infestations between 2019 and 2025, though there were multiple pest-related complaints in 2025. An elevator emergency stop switch was found inoperative in late 2021, and various other elevator-related violations were issued between 2019 and 2020. The property has successfully passed rodent inspections in 2012 and 2022, indicating generally good pest management practices.
