478 21st Ave, San Francisco, CA 94121

This two-unit, two-story multi-family residential building located at 478 21st Avenue in the Central Richmond neighborhood was built in 1922 and is currently owned by Marvin Moy and Linda Yee. The property's maintenance history shows several significant improvements over the years, including a completed kitchen and bathroom remodel in the upper unit in 2002 valued at $20,000, reroofing work completed in 1993, and various street space and sidewalk-related permits from 2010 and 2013.

The building underwent an expired permit inspection in 1989 that required renewal in 1991, though specific details of this work are not provided in the records. The property has experienced recurring issues with parking violations, particularly regarding driveway blocking, with six such incidents recorded between 2021 and 2024, resulting in multiple citations and at least one tow. A parking on sidewalk incident was documented in 2019.

There have been two street and sidewalk cleaning requests recorded in 2021, one regarding loose garbage and another in 2011 related to illegal dumping. Sidewalk maintenance attention was required in 2011, and a sidewalk defect was reported that same year. While the parking violations are a notable pattern in the building's recent history, the overall maintenance record indicates regular upkeep of the property and surrounding infrastructure, with no recorded safety incidents or structural issues directly affecting the building itself.
