142-144 Duncan St, San Francisco, CA 94110
The two-unit residential building at 142-144 Duncan Street in Noe Valley, owned by the Susan Faye Comstock Revocable Trust, has undergone several significant improvements since 2010. The most recent major renovation was completed in September 2021, when a new gas fireplace was installed in the top unit (142 Duncan) using existing infrastructure. Prior to this, in 2020, repairs were made to address dry rot on the west side of the building, and in 2018, the property received new double-hung wood windows and fixed wood sashes.
The building has also seen substantial structural improvements, including partial foundation replacement and ground floor structural enhancements in 2010, which cost $30,000. Earlier improvements included a significant electrical upgrade in 2006, when the electrical system was modernized with new meter sockets and a house panel installation. The property has had some infrastructure work as well, including plumbing repairs to the underground sewer line in 2010.
The building's maintenance history shows regular upkeep and modernization efforts, particularly focusing on safety and comfort improvements. The surrounding area has experienced typical urban challenges, as evidenced by multiple reports of abandoned vehicles (all of which were resolved when vehicles were found to be gone upon inspection) between 2015 and 2023, and a main water break incident in 2022. The building's recent maintenance record suggests active management, with no recorded safety violations or significant resident impact issues in recent years.
