Augrented Insights Report for 520 Williams Avenue

520 Williams Avenue is a 4-story, 16-unit residential building constructed in 1930 and currently owned by Meredith Marshall. The building has experienced recurring heating and hot water issues in recent years, with multiple complaints documented between 2019-2024, though inspections generally found no violations. Most recently, in early 2024, there were complaints about heating and hot water problems affecting the entire building, as well as reports of mold (unsanitary conditions).

An August 2023 complaint regarding an electric/gas range was also filed and closed. The building is currently facing several maintenance challenges, particularly in apartment 2A, which has multiple open violations from a May 2024 inspection. These include issues with water leaks, plaster surfaces, door problems, and an active mice infestation.

The property had some regulatory compliance issues in 2023 related to external low-pressure inspections, though these violations were ultimately dismissed in December 2023. On a positive note, the building has maintained zero bedbug reports in recent years, with only one reported case in 2021 that was promptly addressed. The building's maintenance history shows a pattern of similar issues recurring over time, particularly regarding heating systems and various maintenance needs in apartment 2A.
