3450-3452 Mission St, San Francisco, CA 94110

The property at 3450-3452 Mission St is a two-story, multi-family residential building with commercial space, constructed in 1900 in the Bernal Heights neighborhood. The building, owned by Yin Nin & Yuk Kuen Siu Trust, contains three residential units and was originally built as a flat with street-level commercial space.

The most significant recent issues have been related to sewer problems, with multiple incidents reported between 2022-2023, including sewage backups, flooding, and odor complaints from the side sewer vent. Of particular concern is an open, accepted 311 call from December 2023 regarding a collapsed sidewalk.

The building has undergone various renovations and maintenance work over the years, including plumbing updates in 2015 with house trap and sewer line replacements, and historical records show reroofing work was performed in 1990 and 2003. A notable commercial history includes the establishment of the Mandarin House SF restaurant, with various approvals for Type 41 Alcohol Beverage Control (ABC) license and restaurant use, which appears to be the current operating business at the location. The property has also experienced some routine municipal issues such as illegal parking incidents and street cleaning needs, but these are generally minor compared to the structural and sewer-related concerns.
