435 Warren Dr, San Francisco, CA 94131

The four-story, 12-unit multi-family residential building at 435 Warren Drive in Forest Knolls, owned by Hsu Pin Wei & Lilly M, was built in 1960 and has undergone several significant maintenance events over its lifetime. Most notably, the building received a $12,000 reroofing project in 2010 that was documented through a building permit. The property has experienced recurring fire safety issues, particularly in 2003 when multiple violations were recorded related to fire safety equipment and emergency access, including problems with fire extinguisher maintenance, fire escape ladders, and storage in garages/parking spaces.

These violations were all abated by August 25, 2003. More recent fire safety concerns were noted between 2015 and 2022, including violations for exit maintenance, fire extinguisher issues, and problems with exits/fire escapes, though records indicate these were generally corrected, with some marked as having "no merit." The building has faced various maintenance and safety inspections over the years, including three routine inspections in 2003, 2009, and 2020. A documented complaint from December 2020 raised concerns about construction exhaust affecting resident units, which was promptly addressed.

The property has experienced some logistical issues, particularly regarding sidewalk parking, with multiple enforcement cases recorded between 2015 and 2023. Building infrastructure issues have been documented, including multiple complaints about pavement defects in the surrounding area between 2015 and 2016, though these were generally resolved by city inspectors. The most recent building activity involves a sidewalk parking complaint from December 2023, though enforcement officers were unable to locate the violating vehicle. While the building has experienced various safety and maintenance issues, records generally indicate that most violations were addressed and resolved through appropriate channels, with the most recent fire safety concerns being corrected promptly.
