Augrented Insights Report

The three-story, 12-unit multi-family residential building at 2430-2440 Folsom Street in the Inner Mission, owned by Woo Donald No 2 Family Ltd, was constructed in 1908 and has undergone significant renovations over the past 15 years. Most recently, in July 2024, Unit A received a comprehensive renovation including kitchen and bathroom updates, wiring improvements, and the replacement of a bathtub with a shower. The building has seen continuous maintenance and upgrades, with multiple renovation projects between 2019-2022 focusing on kitchen and bathroom improvements, window replacements, and electrical system updates.

However, there are concerning active violations and complaints that warrant attention, including unresolved issues from 2023 regarding smoke detectors and building compliance affidavits, as well as a 2017 complaint about plumbing and electrical problems including a leaking sink, non-functioning refrigerator, and missing smoke detectors. The property has experienced various maintenance challenges over the years, with past complaints documenting issues such as water damage, rodent problems, heating failures, and ceiling collapse in 2020. Historical improvements to the building include the installation of 91 vinyl windows in 2010, conversion of overhead service to underground in 2005, and various electrical upgrades including panel replacements and rewiring of units.

The building has also undergone multiple HVAC system improvements, with furnace replacements and upgrades documented between 2011-2022. Recent external issues have been limited to street-related matters such as sidewalk cleaning and tree maintenance as recorded in 2024, suggesting ongoing attention to basic building upkeep. While the extensive renovation history indicates significant investment in the property's maintenance and improvement, the presence of active violations related to safety systems and building compliance suggests some ongoing maintenance oversight challenges.
