The Knox Family Trust 2001 owns this 4-unit, 2-story multi-family residential building located in Noe Valley, built in 1906. The property has undergone several significant improvements over the past two decades, with the most substantial recent work occurring between 2015-2016 when major structural modifications were implemented, including the construction of both a spiral staircase to the basement and a 'U'-shaped stair from the 2nd floor to basement, along with related electrical and plumbing work totaling approximately $77,600.

These projects were marked by some controversy, with a complaint filed in March 2016 regarding unpermitted excavation work potentially affecting neighboring structures, though this complaint is now listed as inactive. The building's history includes several maintenance and safety improvement projects, such as a direct vent gas insert installation in 2021 and various stair and deck repairs. In 2001, the property underwent a routine apartment house inspection that resulted in multiple fire safety violations, including issues with security bars, combustible storage, and fire proofing materials, though all these violations were abated by March 2001.

The building has also seen regular maintenance work, including reroofing in 2003 and various plumbing and electrical updates. Recent activity in the area has primarily involved municipal services, with several parking enforcement requests and tree maintenance calls in 2023-2024. A curb defect complaint from September 2024 is currently open, though this is a street infrastructure issue rather than a building concern.
