915-917 Anza St, San Francisco, CA 94118

The 2-unit multi-family residential building at 915-917 Anza Street in the Lone Mountain neighborhood is a 2-story flats and duplex structure built in 1938, currently owned by Albert L Ng Bypass Tr. The property experienced a significant structural incident in October 2010 when a vehicle collision caused substantial damage to the west exterior wall, particularly affecting the electrical panel and gas meter, with reports indicating the wall was displaced by 12 to 18 inches and resulted in a gas leak that required PG&E intervention.

This incident triggered emergency repairs, including plumbing work on the gas lines, electrical system modifications to relocate underground service and panels, and reinforcements such as the installation of wedge anchors to secure the mud sill to the foundation. All repairs related to the incident were completed by the end of 2010 and the building was declared safe by December 2011. In recent years, the property has experienced recurring issues with mailbox graffiti, with multiple reports in 2022, 2023, and 2024, though these are external to the building itself and typically handled by the US Postal Service.

The property has some ongoing infrastructure concerns, including an open case from 2019 regarding sidewalk defects caused by tree roots. While these external issues persist, there have been no reported building violations or structural concerns since the 2010 incident, and all identified building permits from that period show as completed. The most recent service requests have primarily concerned external maintenance matters rather than building systems or structural integrity.
