526-528 20th Ave, San Francisco, CA 94121

The property at 526-528 20th Avenue in San Francisco's Central Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1921, currently owned by the Rose G Bucklin Survivors Trust. The building has undergone several significant infrastructure improvements over the past decade, including a comprehensive whole-house water repipe in 2015, trenchless sewer replacement in 2016, and two furnace replacements in 2008.

Historical records show exterior stair repairs were completed in 1989. The building's maintenance history suggests regular upkeep of essential systems, with recent permit activity limited to street space usage in 2018, 2016, and 2007. The property has experienced recurring issues with illegal parking, particularly vehicles parking on the sidewalk, with multiple citations issued between 2020 and 2023.

There was also one incident of driveway blocking reported in January 2025, though officers were unable to locate the offending vehicle. Additional community issues have included instances of graffiti (February 2023, subsequently unaddressed due to lack of response) and periods requiring general street cleaning (August 2021 and April 2020). While these external issues do not directly impact the building's internal conditions, they do reflect some neighborhood challenges related to parking enforcement and street maintenance in the immediate vicinity.
