778-784 21st Ave, San Francisco, CA 94121

The four-unit, two-story multi-family residential building at 778-784 21st Ave in the Central Richmond neighborhood, owned by Allan & Tina Jin Revocable, has a documented history dating back to its construction in 1921. The most significant events occurred in late 2002 when the building faced multiple fire safety violations, including requirements for smoke enclosure doors, door closers, and automatic fire sprinklers over garbage receptacles.

These violations were all addressed and abated by January 29, 2003, along with some plumbing and electrical issues that were corrected through specific electrical work completed in November 2002 and subsequent building permits in January 2003. The property has undergone routine safety inspections in 2011 and 2014, with the latter involving an issue with paint sanding containment.

More recent history shows the building has maintained compliance with housing regulations since 2003, though there have been various street-related issues in the vicinity, including several reports of parking violations between 2021-2024 and occasional garbage-related complaints. The most recent concerns involve an open 311 call from December 2024 regarding glass debris, and a rent board inquiry from July 2024, though neither directly pertains to the building's condition or safety systems. While the building had several violations and required corrections in 2002-2003, there have been no similar patterns of violations or safety concerns in the past two decades, suggesting improved maintenance practices since the early 2000s corrections were implemented.
