Augrented Insights Report

The two-unit multi-family residential building at 645-647 Bosworth Street in Glen Park, owned by the Rosemary L Woo Living Trust, was constructed in 1911 and features two stories with a flat & store configuration. The property has undergone several significant improvements over the past few decades, including a 1988 horizontal addition that enclosed space below street level, the installation of a new dry cleaning machine in 2009 (valued at $47,500), and most recently, in 2020, the replacement of deck floor tiles and waterproofing membrane at the rear of the building.

In 2019, the property underwent improvements to comply with the Accessible Business Entrance ordinance, including the installation of ADA-compliant signage and a bell for curbside service. The building's recent history has seen multiple infrastructure and maintenance issues in the immediate vicinity, particularly in late 2024, with eight reports of garbage and debris requiring city intervention between November and December 2024. These incidents, while primarily external to the building itself, may impact resident experience.

There was also one reported issue regarding a damaged tree in December 2024 that was subsequently resolved. The property's maintenance record shows regular upkeep of essential systems, including roofing work in 1992 and the aforementioned deck improvements, though the deck's renovation represents less than 50% of the total area. All permitted work has been completed, with no outstanding violations or permits, suggesting proper adherence to building regulations and maintenance requirements.
