1140 Sanchez St, San Francisco, CA 94114

The 1140 Sanchez Street property in Noe Valley is a three-story, four-unit multi-family residential building constructed in 1923, currently owned by Chan Yau-gene. The building has undergone several significant renovations and experienced multiple maintenance challenges over the past decade. Most notably, in 2017, the building faced serious maintenance issues including water damage, electrical problems, and heating system failures, which resulted in multiple violation notices that were not fully resolved until late 2018.

Recent concerns have emerged regarding potential mold issues, with a complaint filed in September 2024 about black mold and water leaks that reportedly marked the third occurrence of these problems. The property underwent substantial improvements in 2012, including a major remodeling project of units #1, #3, and #4 costing $160,000, which involved kitchen relocations, bathroom additions, and washer/dryer installations. Additional work included the replacement of windows in 2012, electrical panel upgrades, and various plumbing and electrical improvements between 2012-2018.

The building has a history of construction-related complaints, particularly in 2012-2013, when several violations were documented regarding work being performed without proper permits and concerns about dust, debris, and potential asbestos. While many of these issues were eventually addressed through various completed permits, the recent mold complaint suggests persistent maintenance challenges. The property has also had recurring issues with parking enforcement, with multiple calls regarding vehicles blocking the driveway between 2023-2024.
