466-468 21st Ave, San Francisco, CA 94121

The two-unit residential building at 466-468 21st Avenue in the Central Richmond neighborhood, owned by Sutadi Peter & Saichol, is a two-story flats and duplex structure built in 1909. The building's official use and occupancy records were documented in 2019, confirming its classification as a three-story, two-residential unit structure based on Sanborn maps and city records.

Significant recent maintenance includes a roof replacement project completed in 2017, where an old roof was removed and double layers of modified bitumen were installed at a cost of $9,000. The property has experienced several maintenance and infrastructure issues over the past decade, with the most notable being two sewage backup incidents in 2015 and 2020 involving 4-inch sewer vents. A recent concern as of March 2023 involves a lifted sidewalk condition that has been reported but remains open.

The building's surroundings have encountered various urban challenges, including several parking-related complaints (sidewalk parking and blocked driveways) between 2019 and 2023, and occasional street cleaning issues such as waste removal in 2015. A CO detector activation due to malfunction was recorded, though no civilian injuries were reported. The building's permit history shows proper documentation of its legal use, with no outstanding compliance issues noted in recent records.
