1251 Silver Ave, San Francisco, CA 94134

The two-unit residential building at 1251 Silver Avenue in the Portola neighborhood, owned by the Cindy S Wong Living Trust, has experienced several maintenance and infrastructure issues over the past year. Most notably, there has been a recurring pattern of sewer-related problems, with multiple sewage back-up incidents recorded through late 2024, including three separate incidents in December 2024 alone.

These sewer issues appear to be an ongoing concern, as similar problems were documented previously in January and November 2024. The building's maintenance history shows attention to basic infrastructure, with roofing work completed in both 1997 and 2010 at a cost of $11,500, and an attempted furnace replacement project in 2012 that appears to have resulted in an expired permit.

In addition to the sewer problems, there have been various other maintenance and environmental concerns documented through 311 calls, including reports of garbage and debris (a mattress in November 2024), graffiti on infrastructure (February 2024), and a general maintenance issue transferred to the Department of Public Health in October 2024. The most recent documented interaction was a normal billing customer callback from the Public Utilities Commission in August 2024.
