The 6-unit, 2-story apartment building at 361 12th Avenue in San Francisco's Inner Richmond neighborhood, constructed in 1964 and currently owned by the David T Chinn Living Trust 2018, has undergone several significant upgrades and improvements over the past two decades. Most notably, in December 2023, the building completed a comprehensive fire alarm system upgrade valued at $28,538, which included the installation of addressable smoke detectors, manual pull stations, horn strobes, and low-frequency horns in residential sleeping areas to meet current fire code requirements.

The building completed a mandatory seismic retrofit in 2015, achieving compliance with San Francisco building codes as a Tier 3 soft-story structure, which included structural modifications and reinforcement of the first floor at a cost of $89,000. The property has a history of bathroom renovations in multiple units, with documented improvements in apartments #1, #3, and #6 between 2005 and 2008, involving the replacement of fixtures, tiles, and plumbing systems.

While the building has experienced some maintenance issues in the past, most notably regarding ventilation in Unit #6 in 2012 and various compliance matters in 2009, all documented violations have been resolved, with Unit #6's ventilation issue being addressed by July 2012. The building's maintenance history includes regular inspections and improvements to keep pace with safety requirements, culminating in the recent fire safety upgrades, which represent the most significant investment in building systems in recent years. The property has also maintained active compliance with housing codes and regulations, with no current active violations as of October 2023.
