447 19th Ave, San Francisco, CA 94121

The two-story, six-unit multi-family residential building at 447 19th Avenue in the Central Richmond neighborhood, owned by Ronald Lim and constructed in 1964, has undergone several significant safety upgrades in recent years. Most notably, in 2023, the building completed a fire alarm system upgrade costing over $17,000 to comply with city fire code requirements, with a related electrical permit issued in November 2023 for installing low-frequency sounders in sleeping areas and updating the fire panel.

The building successfully completed a mandatory soft-story earthquake retrofit in 2015, meeting Tier 3 requirements at a cost of $60,000, demonstrating compliance with seismic safety standards. The building's maintenance history indicates some past challenges with safety systems and building infrastructure, including multiple fire safety violations in 2002-2004 related to fire extinguisher maintenance, which were all resolved by 2009.

A hot water supply issue was documented in 2004 and resolved by 2009. While routine housing inspections have generally shown compliance, there have been several reports of garbage and debris issues in recent years (2024-2025), though these were related to street cleaning concerns outside the building rather than interior maintenance issues. The most recent building improvements focus on life safety systems, particularly fire alarm infrastructure, with no active violations or complaints currently on record, suggesting improved overall maintenance and safety compliance in recent years.
