Augrented Insights Report for 645 Willoughby Avenue

645 Willoughby Avenue is a four-story, eight-unit Old Law Tenement building constructed in 1931 and currently owned by Throop Corners LLC. The building has experienced several recurrent maintenance issues over recent years, with the most significant recent problems occurring between November 2024 and March 2025, including pest infestations in Apartment 5 (verified mouse and roach infestations with violations issued) and water-related issues such as damp spots and mold in October 2023.

The building has a documented history of heat and hot water problems, with violations in 2022 affecting both individual apartments and the entire building. Safety concerns have also been documented, including fire escape and security issues in 2022. The property has undergone regular rodent inspections between 2022 and 2025, with most recent inspections in 2024 and 2025 passing without issues, though there were reports of rat activity in April and May 2022.

Multiple violations have been issued and subsequently closed, including issues with carbon monoxide detectors in Apartments 6 and 8, various plumbing and safety concerns, and building-wide heating system problems. The building's maintenance history has shown some positive trends, with bedbug reports consistently recording zero infestations since 2020, and the most recent rodent inspections indicating compliance with pest control requirements. While many past violations have been addressed and closed, the recurring nature of pest and water-related issues suggests ongoing maintenance challenges.
