Augrented Insights Report for 4109 7th Avenue

The four-story, 16-unit tenement building at 4109 7th Avenue in Sunset Park, owned by Scott Castellano, has experienced persistent maintenance challenges in recent years, particularly in terms of heating and safety systems. The property has documented multiple heat and hot water complaints in 2024-2025, including a January 2025 incident affecting the entire building, and several inspections in late 2024 where Housing Preservation and Development (HPD) was unable to complete their evaluations. A significant cluster of complaints in September 2024 related to various maintenance issues including appliance functionality, wall and ceiling conditions, flooring, and window problems, though inspections were not completed.

More recently, in May 2025, there were multiple emergency complaints regarding safety systems including fire escapes, smoke detectors, and carbon monoxide detectors, along with plumbing issues that were subsequently addressed and closed. Historical records reveal past building system concerns, including a 2021 electrical wiring violation and a 2019 boiler-related citation, though these were resolved. The building has maintained a clean record regarding bedbugs since 2020, with annual filings showing no infestations or eradications.

Rodent inspections show variable results, with rat activity noted in 2020 and compliance achieved in 2021. The property has undergone various repairs and maintenance corrections as evidenced by violation certification dates, indicating some level of ongoing attention to building systems and safety requirements. The building's compliance history shows a pattern of recurrent heating system issues and safety system concerns, particularly in recent years, while also demonstrating some capability to address and resolve violations when formally cited.
