423-425 12th Ave, San Francisco, CA 94118

The Shen Family Trust owns this two-unit, two-story multi-family residential building, constructed in 1922 in San Francisco's Inner Richmond neighborhood. The property has undergone several significant renovations over the years, most notably in 2009-2010 when both units received substantial updates including kitchen and bathroom remodels, with the work properly documented through building, plumbing, and electrical permits.

A solar panel system was installed in 2014, consisting of 26 roof-mounted PV modules with a total rating of 6.63kW. A concerning series of events occurred between 2018-2019, including complaints about unpermitted dwelling units with a stove and bathroom behind the garage (allegedly used for short-term rentals), and construction activity without proper permits.

The building has experienced recurring sewer issues, with multiple incidents reported between 2015-2020, though these were ultimately resolved through proper channels. Some maintenance challenges have been documented, including mold remediation in 2006 and one instance of fire damage repair in 1997 that required fixing the backyard stairway. The property has had several recent 311 calls regarding street-related issues such as abandoned vehicles and waste, though these are more related to the neighborhood than the building itself.
