2124-2128 Mason St, San Francisco, CA 94133

The three-unit multi-family residential building at 2124-2128 Mason Street in North Beach is a three-story flats and duplex structure built in 1911, currently owned by Kennard & Helen Yim Lee Trust. The building underwent a significant cluster of housing violations in January 2006, primarily related to safety concerns, including issues with smoke detectors, wood stairs requiring repair, fire extinguisher maintenance, and gas meter instructions.

All these violations were addressed and fully abated by April 3, 2006. The building has maintained regular housing inspections since 1999, with previous routine inspections in 1999 and 2003 showing no significant issues. In recent years, the property has required two street space permits, one issued in 2007 and another in 2016, though the costs were minimal ($0.00 for 2007 and $1.00 for 2016).

The surrounding area has experienced various municipal service calls between 2020 and 2025, primarily related to street cleaning, including reports of loose garbage, graffiti removal, and occasional encampment situations. These external issues generally reflect neighborhood conditions rather than building-specific problems. While the building experienced multiple service calls for street and sidewalk cleaning between 2020 and 2025, these were primarily related to public space maintenance rather than building-specific concerns, suggesting ongoing attention to exterior upkeep in the surrounding area.
