Augrented Insights Report for 324 91st Street

The 6-unit, 3-story apartment building at 324 91st Street in Fort Hamilton, owned by Alexander Karahalios, has experienced several concerning maintenance issues over the past few years, with the most significant problems occurring in 2024. The property has faced recurrent pest-related complaints throughout 2024, with multiple reports of unsanitary conditions related to pests between April and July, as well as issues with garbage/recycling storage.

Three separate HPD inspections in 2024 resulted in violations being issued, particularly in July 2024, when the building was cited for multiple safety concerns, including blocking egress from fire escapes with flower pots, improper storage of household articles in hallways and stairs, and the need for a gas leak safety notice in a common area. The building's maintenance history shows a pattern of ongoing concerns about basic building systems and safety compliance. In 2024 alone, there were violations noted for a disconnected steam supply line, defective self-closing doors, and encumbrances blocking hallways and stairways.

The property has also faced challenges with rodent control, though recent inspections in 2024 (April and June) passed without violations. While previous years showed similar pest issues and maintenance violations, including a 2022 emergency complaint for sewage and problems with electrical outlets, the building has maintained a clean record for bedbugs since at least 2020, with no reported infestations in any dwelling units during recent reporting periods. The building is currently showing one active Department of Buildings violation related to the failure to file a 2018 external low-pressure inspection, which has been pending since June 2023.
