579 43rd Ave, San Francisco, CA 94121
The three-unit multi-family residential building at 579 43rd Avenue in the Outer Richmond district, owned by the Auyoung Family Trust, has experienced several notable events in recent years. Most concerning is a pattern of sewer-related issues, with four documented sewage back-up incidents from catch basins occurring in July, August, and September 2024, suggesting an ongoing infrastructure challenge.
The property has also faced noise-related complaints in March 2024, with multiple reports filed through the 311 system, though these cases were ultimately transferred or cancelled. Prior building maintenance history includes a reroofing project from 2003 (permit expired) and stucco dryrot repairs completed in 1997 on the building's frontal portion.
Other recent incidents include an abandoned vehicle report (August 2024) and a garbage/debris complaint (July 2024), though these are less significant in terms of resident impact. The building's design is typical of its 1948 construction date, featuring two stories and classified as Flats & Duplex within the multi-family residential category.
