662 Clayton St, San Francisco, CA 94117

The 12-unit, three-story apartment building at 662 Clayton Street in Haight Ashbury, owned by Survivors Trust, was constructed in 1904 and has undergone several significant modifications and faced various maintenance challenges. The most substantial recent infrastructure improvement occurred in 2017 with a sewer repair/replacement project.

Between 2001 and 2002, the building underwent notable safety system upgrades, including the installation of additional fire alarm components such as smoke detectors and horns, along with the replacement of fire sprinkler heads. Historical records show the building experienced a fire incident in 1988 that required roof repairs, and a significant vertical addition project was completed in 2001 expanding first-story space into the basement level. Recent inspections in 2022 and 2006 reveal periodic oversight by housing authorities, with the most recent routine inspection from 2022 still marked as active.

The building has maintained regular compliance with fire safety regulations, though there have been recurring fire alarm system malfunctions and false alarms between 2009 and 2022, which were always resolved without injuries. A notable security incident occurred in 2001 when tenants reported being robbed due to inadequate locking systems, resulting in multiple security-related violations that were promptly abated. Recent activity from late 2024 through early 2025 shows ongoing maintenance issues in the surrounding area, with multiple reports of garbage, debris, and sidewalk cleaning needs, though these external issues do not directly impact the building's internal conditions.
