520 Parker Ave, San Francisco, CA 94118

The 17-unit, 3-story apartment building at 520 Parker Avenue in the Lone Mountain neighborhood, owned by the O'neill Family Trust, has undergone several significant maintenance and safety improvements since its construction in 1960. Most notably, the building completed its mandatory soft-story retrofit in 2017 at a cost of $30,000, demonstrating compliance with San Francisco's seismic safety requirements.

The building has an extensive history of addressing various maintenance issues, including multiple instances of wood replacement in the mid-1990s due to rot, and more recent fire safety concerns including sprinkler system inspections, exit maintenance, and alarm system checks through 2024. The property has experienced recurring maintenance and safety challenges, particularly in the early 2000s when multiple violations were documented between 2000 and 2004, addressing issues such as weatherproofing, ceiling repairs, plumbing problems, sanitation concerns, rodent infestation, and central alarm system repairs.

While these violations were eventually abated, they indicate a period of significant maintenance requirements. More recent concerns have been primarily focused on fire safety systems, with the most recent complaint in July 2024 regarding exit maintenance, which was corrected by October 2024. The building has also experienced occasional issues with graffiti and sidewalk debris, as evidenced by multiple 311 calls from 2013 through 2024, though these are more related to general building surroundings than structural or safety concerns.
