120 Fair Oaks St, San Francisco, CA 94110

The two-unit, two-story multi-family residential building at 120 Fair Oaks Street in Noe Valley, constructed in 1900, has undergone several significant infrastructure improvements over the past two decades. Most notably, there have been recurring sewer system issues, with three documented sewage back-up incidents in 2024 (August, September, and December), and two open cases related to a tree root problem potentially causing sewer damage (as of October 2023).

The property's maintenance record shows attention to essential systems, including a 2016 house trap replacement (plumbing), a 2014 complete reroofing project, and significant electrical upgrades in 2009 (new service panel installation) and 2006 (solar PV system installation). Historical permits indicate earlier renovations, including kitchen remodels in 1984 and 1997, and foundational work from 1994 involving moisture barrier installation and ratproofing.

The building's recent history shows several external maintenance issues typical for the area, including recent cases of flooding, garbage and debris concerns, and parking violations, though these primarily relate to public space rather than direct building maintenance. The property has maintained compliance with necessary inspections and permits, though multiple historical permits have since expired, including those from 1989 (termite report) and 1994 (crawl space work).
