474 20th Ave, San Francisco, CA 94121

The 6-unit, 2-story apartment building at 474 20th Avenue in the Central Richmond neighborhood, owned by the Yok S Gee Residuary Trust, was constructed in 1963 and has undergone several significant safety improvements over the years. Most recently, in September 2023, the building completed an upgrade to its fire alarm system, adding low-frequency sounders in sleeping areas to improve compliance with fire safety codes. In 2022, the building received a substantial fire alarm system upgrade costing over $24,500, which included replacing devices and installing a monitored communication system.

The building successfully completed its mandatory soft-story retrofit in 2017, demonstrating structural safety compliance with San Francisco building codes. The building's maintenance history shows attention to basic infrastructure, including two reroofing projects (1992 and 2006). A cluster of violations from May 2000 related to fire safety equipment and gas shutoff tools was promptly addressed within three months.

While there have been periodic 311 calls regarding the vicinity of the building, these primarily concern street-related issues such as abandoned vehicles and parking violations, rather than building-specific problems. The fire incident history shows only false alarms and non-injurious incidents, with no significant fire safety concerns reported since 2006. The building's management has demonstrated ongoing commitment to maintaining safety standards through regular updates to fire alarm systems and compliance with seismic safety requirements.
