1314 43rd Ave, San Francisco, CA 94122

1314 43rd Avenue is a two-story, three-unit multi-family residential building located in San Francisco's Outer Sunset neighborhood, constructed in 1973 and owned by Mabel Shum Revocable Living Trust. The property has undergone several significant events, most notably in 2017 when multiple violations were documented, including issues with fire safety, lead hazards, interior surfaces, and smoke detector requirements, though these violations were all abated by August 2018. During the same period, there were complaints regarding unauthorized unit conversions, with allegations of illegally converting the three-unit building into six units.

The building underwent some legitimate modifications in 2009, including bathroom and living space improvements in unit C, and a water heater replacement was completed in 2017. Historical records show earlier concerns including bug infestation in 2012, unauthorized bedroom constructions in 2008, and routine inspections in 1998 and 2002, indicating ongoing regulatory oversight of the property. More recent records from 2023-2024 show primarily external issues, including multiple instances of driveway blocking (with several citations issued), tree maintenance needs, and general cleaning requirements.

These exterior matters, while requiring attention, generally have less impact on tenant safety and building integrity compared to the historical interior and structural violations. The building's documented history shows periods of maintenance and upgrade activity, particularly in addressing safety and compliance issues, though there were notable concerns about unauthorized modifications in 2017 that suggest some regulatory compliance challenges. The property has maintained its three-unit designation according to the building data, despite past complaints about unauthorized unit conversions.
