120-122 Coso Ave, San Francisco, CA 94110

The two-unit residential building at 120-122 Coso Avenue in Bernal Heights is a two-story structure built in 1900, currently owned by Drew Tamsen. The building's documented history reveals several maintenance and compliance matters spanning multiple years. In 2021, significant roofing work was completed at a cost of $14,360, involving the installation of a three-ply modified bitumen system on the back flat roof.

That same year, a formal determination was made regarding the building's legal two-unit, two-story classification based on city records and site inspection. Prior to these improvements, there were some concerning issues on record, including a 2014 complaint about uneven stairs creating trip hazards, and a 2010 incident regarding an unauthorized side addition, though the latter was promptly addressed the same day. The property's more recent history (2019-2025) has primarily involved external factors affecting the vicinity rather than direct building concerns.

There have been multiple reports of vehicles blocking the driveway between 2019 and 2025, with varying degrees of enforcement response. Other incidents have included noise complaints from a major event venue, a graffiti report on ATT property, a collapsed sidewalk concern (which could not be verified by inspection), and a hazardous materials report involving glass on the street. The building's structural integrity appears to have been actively maintained, as evidenced by the documented roofing work, and there haven't been any recent building complaints regarding the structure itself. Most recent incidents have been exterior matters such as street parking issues, sidewalk maintenance, and temporary urban disturbances rather than problems with the building's systems or structure.
