Augrented Insights Report for 415 Leonard Street

415 Leonard Street is a 7-story, 54-unit residential building located in Williamsburg, Brooklyn, built in 2006 and currently owned by Alec Greenberg. The property has experienced several significant maintenance and safety issues over the past few years. Most recently, in June 2024, the Department of Health found violations related to rodent activity, with multiple inspections in 2024 and 2025 confirming "Rat Activity" on the premises.

The building has also faced recurring heat and hot water issues, with multiple complaints documented between July 2018 and October 2018, during which violations were issued. More recent safety concerns include open violations from March 2023 regarding defective smoke detectors and carbon monoxide devices in Apartment 1F, as well as an open violation concerning an illegal electromagnetic locking device at the first-story vestibule door. The building has maintained a clean record regarding bedbug infestations, with all annual reports from 2018 through 2024 showing zero infested or re-infested dwelling units.

However, there are two active Department of Buildings violations related to energy efficiency score display requirements (from 2021 and 2023) and a recent parking structure inspection report violation from October 2024 with a $2,500 penalty. The property has had various inspection and compliance issues over the years, including a 2020 window guard safety complaint and a 2019 cooking gas issue, both of which were closed without violations being confirmed upon inspection. Despite these challenges, the building has shown responsiveness to some violations, as evidenced by the July 2023 certification of previously identified issues regarding smoke detectors, vestibule door repairs, and other safety-related matters.
