757 21st Ave, San Francisco, CA 94121

The two-unit residential building at 757 21st Avenue in San Francisco's Central Richmond district is a two-story flats and duplex structure owned by the Henry & Wah Hsung Yee Trust, constructed in 1923. Historical records show minimal major maintenance activity, with the only significant building permit on file being for reroofing work completed in 1992.

The property's surrounding area has experienced several street-level maintenance issues over the past decade, with multiple reports of loose garbage requiring general cleaning in 2020, 2021, and most recently in March 2024. There have been some notable safety concerns in the immediate vicinity, including a recent April 2024 incident involving medical waste (initially reported as needles, but later identified as an electric wheelchair that was secured to a street pole), though this was promptly resolved.

The location has also experienced some parking-related issues, with a driveway blocking incident in December 2018 that resulted in a citation, and an abandoned vehicle report in September 2013, though in that case the vehicle was gone when authorities arrived for inspection. While these external maintenance issues have been relatively consistent over the years, they predominantly relate to street and sidewalk conditions rather than the building itself.
