2330 20th Ave, San Francisco, CA 94116

The 2330 20th Avenue property, a two-story flats and duplex building owned by the Chan Family Trust, was constructed in 1927 and has undergone at least one significant modification: in 1994, a permit was granted and completed for adding two bedrooms, one bathroom, a social room in the basement, and a hallway. The building has experienced several notable issues over the past decade, with particular concerns around sewer infrastructure.

There were two documented sewer-related incidents, including a sewage backup in December 2020 and a sewage discharge issue in January 2025, though both cases were resolved without major complications. The property has seen recurring parking-related challenges, particularly during 2022-2023, with five documented incidents involving vehicles illegally parking on sidewalks.

These incidents resulted in various enforcement actions, including citations and verbal warnings. Additional concerns have included waste management issues, with recorded complaints about refuse containers being left out continuously in May 2012, which was addressed through official correspondence. While these issues have been addressed as they arose, the frequency of parking violations and sewer-related problems suggests areas requiring ongoing monitoring.
