435 15th Ave, San Francisco, CA 94118

The 6-unit, 3-story multi-family residential building at 435 15th Avenue in the Central Richmond neighborhood was constructed in 1924 and is currently owned by the Choy Family Trust A. The building has undergone several significant improvements over the past decade, most notably completing a mandatory soft-story retrofit in 2015 (classified as Tier 3) at a cost of $45,000, demonstrating compliance with seismic safety requirements.

During this retrofit, additional dry rot repairs were necessary and completed in 2016 around the garage door opening. The building's maintenance history shows attention to infrastructure needs, including sewer pipe repairs in 2013, and historical documentation reveals termite repairs were performed in 1988, along with building code compliance work in 1984. A comprehensive routine inspection in 2002 resulted in multiple violations related to fire safety and security that were all promptly addressed and abated by September 25, 2002.

These violations included issues with fire escape ladders, smoke enclosure doors, fire extinguishers, and security locks, indicating a period of significant attention to safety systems. While there was a fire alarm system issue recorded in 2006 that was corrected, more recent building history shows no active fire safety violations. The most pressing recent maintenance work involved addressing dry rot during seismic upgrades, while the most recent building-related incidents recorded through 311 calls were limited to external issues (parking and sidewalk cleaning) that do not directly impact building habitability.
