358 2nd Ave, San Francisco, CA 94118

The 2-story, 3-unit multi-family residential building at 358 2nd Avenue in the Inner Richmond, owned by Cheng Thomas, was constructed in 1977 and has undergone several significant improvements over the past decades. The most recent major work includes the installation of 27 fire sprinklers on the ground floor in July 2023, with an associated cost of $25,415, as part of a broader fire safety upgrade involving a new electrical fire alarm system and low-frequency sounders in sleeping areas scheduled for April 2024.

The property has seen substantial modernization efforts, including a voluntary seismic retrofit in late 2019 ($10,000) and the attempted conversion of the 1st-floor garage area into an ADU (Accessory Dwelling Unit) between 2017-2021, although earlier attempts at this project were cancelled. Both the second-floor unit #2 (2017) and unit #1 (2015) have received substantial interior renovations, including kitchen and bathroom upgrades.

The building has maintained regular compliance with safety inspections, with no active violations since 2004 related to smoke detectors, emergency exits, and fire extinguisher maintenance, which were promptly addressed within weeks of being cited. A notable historical issue occurred in 1998 with a sewage backflow problem from the sidewalk sewer vent that had previously affected the property during a city main break, and while this remains active in records, it may no longer be relevant given the extensive subsequent improvements to the building's infrastructure.
