376 21st Ave, San Francisco, CA 94121

The three-story, 15-unit apartment building at 376 21st Avenue in the Central Richmond neighborhood, built in 1963, has undergone several significant improvements and faced various challenges over the years. Most notably, the building completed a mandatory soft-story seismic retrofit in 2016, bringing it into compliance with San Francisco's building codes, at a cost of $85,000. The building has experienced recurring issues with moisture and maintenance, particularly in Unit #104, with multiple complaints about mold, mildew, and water-related problems between 2010-2011.

The property has maintained its fire safety systems relatively well, though there have been several fire alarm system-related violations between 2006 and 2024, with the most recent violation in May 2024 requiring correction. The building's maintenance history shows attention to structural issues, including dry rot repairs in 2003 and 2011, and a complete window replacement project in 2006 that involved installing 51 new vinyl windows. Recent concerns have centered around building systems, such as a 2017 complaint regarding PG&E gas service location below the slab, which was determined to be a plumbing code violation.

While the building has had some violations and complaints over the years, most have been resolved through proper channels. The property appears to be generally well-maintained in recent years, with completed seismic retrofitting and periodic maintenance activities, though there is ongoing attention required for fire alarm system maintenance as evidenced by the most recent violation. Recent 311 calls (2024-2025) primarily relate to street-level issues such as garbage management and parking concerns, which are not directly related to building conditions.
