771-773 24th Ave, San Francisco, CA 94121

The Tang Family Trust-owned duplex at 771-773 24th Avenue, located in San Francisco's Central Richmond neighborhood, is a three-story multi-family residential building constructed in 1923. The property has undergone several significant renovations, most notably a comprehensive modernization project completed in 2008-2009 that included complete rewiring of the building, remodeling of kitchens and bathrooms on the second and third floors, and the addition of a new bathroom on the ground floor, along with plumbing work for new gas lines and various electrical upgrades including installation of 12 smoke detectors and new 200-amp service.

The most recent major maintenance work was a reroofing project completed in May 2024 at a cost of $22,800. The building has experienced some maintenance and accessibility issues in recent months, with several 311 calls between 2023-2024 reporting problems including a blocked sidewalk (resolved), overgrown trees (open), and curb defects (open as of November 2023).

There have been multiple reports of driveway blocking incidents in 2024, though these were generally not resolved through police intervention. The property has also required attention to public space compliance, with open cases regarding clear paths of travel in shared spaces and an unspecified general request to SFUSD that received no response. While these recent issues indicate some ongoing maintenance and accessibility challenges in the immediate vicinity of the property, the extensive renovation work completed in 2008-2009 demonstrates a significant investment in the building's infrastructure and systems.
