21-23 Sutro Heights Ave, San Francisco, CA 94121

The two-unit residential building at 21-23 Sutro Heights Avenue, constructed in 1947, is currently owned by Eric Chau and Sandy Zhao. The two-story flats and duplex structure has undergone several significant improvements in recent years, with the most notable being a July 2021 project that included kitchen and bathroom renovations, dry rot repairs, and an ambitious plan to convert the first-floor utility area/garage into a new 381-square-foot ADU (Accessory Dwelling Unit), for which the permit is still listed as filed.

The building has also seen substantial infrastructure upgrades, including an electrical service upgrade to 200 amps completed in 2006, and historical window replacements in 1994 and 1997. The property has experienced a series of recurring issues with abandoned vehicles in the vicinity between 2021 and 2023, with multiple reports of vehicles requiring attention, though all were resolved upon inspection.

A notable incident occurred in May 2022 involving a café's tables and chairs blocking the sidewalk, which was promptly addressed. The building's maintenance history suggests regular upkeep, with specific attention to structural elements such as exterior stairs (repaired in 1991) and various window modifications. The most recent building-related activity was a resolved interior remodel complaint in July 2021, indicating that all work was conducted in compliance with building codes.
