347 20th Ave, San Francisco, CA 94121

The property at 347 20th Avenue in the Central Richmond neighborhood is a 2-story, 4-unit multi-family residential building constructed in 1907, currently owned by Tat Man & Sharon W Cheung R. The building has undergone several significant maintenance and safety-related improvements over the past three decades. Most notably, in 2022, there were reports of mold and mildew issues that were transferred to the Department of Public Health's Environmental Health division for investigation.

The building has experienced two routine inspections that resulted in multiple violations: in 2002, the property was cited for various safety concerns including smoke detector requirements, egress obstructions, and the need for building permits, all of which were abated by January 2003. A subsequent inspection in 2009 resulted in violations regarding fire safety (fire extinguisher recharge), security (entry door locks), and sanitation (rubbish removal), though these issues were also resolved by December 2009. The building's maintenance history includes a complete reroofing in 2003 ($3,500) and repairs to front exterior wood stairs in 1992.

Recent exterior issues have been documented, including a 2022 sidewalk collapse that was deemed low priority for city intervention, and multiple reports of loose garbage requiring general cleaning between 2021-2024. The property has encountered recurring parking issues in the vicinity, with multiple 311 calls reporting vehicles blocking sidewalks, though these are more related to street conditions than building maintenance. The most recent complaints as of 2024 have been primarily focused on parking violations and sidewalk cleaning, suggesting ongoing but relatively minor external maintenance issues compared to the more significant safety violations addressed in previous years.
