279 12th Ave, San Francisco, CA 94118

The Wong Family Trust owns this two-unit, two-story residential building located at 279 12th Ave in San Francisco's Inner Richmond neighborhood. Built in 1908, this flats/duplex property has experienced multiple infrastructure challenges over the years, with the most notable recurring issue being sewer system problems.

Between 2008 and 2022, there have been at least four documented incidents involving sewage backups or sewer issues, affecting both the property and street infrastructure. The most recent sewer-related incident occurred in January 2022, involving a 4-inch sewer vent problem that required fieldwork to resolve. While a street space permit was issued in 2012 for this location, the only other documented infrastructure issue was a sidewalk defect in March 2014, where a collapsed sidewalk was investigated but not found to be present upon inspection.

The property has experienced occasional quality-of-life issues in its surrounding area, including instances of graffiti in 2013 and 2015, and environmental health concerns in late 2021 that required transfer to the Department of Public Health's Environmental Health division. Most recently, in August 2024, there was an encampment-related report, though this case was ultimately closed due to the location being unable to be determined. It's worth noting that many of these environmental and infrastructure issues, while resolved, suggest attention to plumbing systems and exterior maintenance has been necessary over the years.
