400 25th Ave, San Francisco, CA 94121

The property at 400 25th Avenue in the Central Richmond neighborhood is a two-story, 8-unit multi-family residential building constructed in 1961, currently owned by the Bing K Chan Decedents Trust. The building has undergone several significant improvements over the years, most notably completing a mandatory seismic retrofit of its soft-story structure in 2015 at a cost of $70,000, bringing it into compliance with San Francisco building codes.

A gas utility inspection was conducted in 2007 for unit #7, which had reportedly not used gas for twenty years, and the building has received various maintenance updates including street space work (2018), meter installations (2015), kitchen cabinet remodeling (2001), and reroofing (1989). The building experienced multiple serious issues in early 2002, with several building violations and complaints filed between January and April of that year, including problems with mold/mildew, water damage, damaged ceilings, fire escape maintenance, combustible storage, fire proofing materials, and egress obstructions. All these violations were officially abated by May 2002.

More recent records indicate routine building maintenance and external upkeep, with several 311 calls in 2023-2024 primarily related to street cleaning and garbage debris on the property perimeter. Fire incident records show three minor incidents: a false alarm, malfunctioning smoke detector, and a smoke scare, none resulting in civilian injuries. The building's soft story retrofit status is marked as completed with a Certificate of Final Completion issued, indicating compliance with seismic safety requirements.
