2448 Folsom St, San Francisco, CA 94110

The two-unit residential building at 2448 Folsom Street in the Inner Mission, owned by Ann Sartor Birenbaum 2007 T, is a two-story flats/duplex structure built in 1900. The property has undergone several significant renovations over the past two decades, with the most substantial work occurring in 2014, when a comprehensive partial interior renovation of the lower unit was completed, including foundation work, new shear walls, windows, doors, and a ground-level deck. This project, valued at $25,000, was accompanied by multiple street space permits and plumbing/electrical work.

Earlier improvements include a window replacement project in 2008 ($6,000) and major structural work in 2005 involving brick foundation removal and concrete replacement ($56,000). The building's infrastructure received attention in 2004 with a 200-amp underground electrical conversion. More recently, the property has experienced various maintenance and public safety issues, with multiple 311 calls in 2023-2024 primarily related to street cleaning, graffiti, and parking concerns.

Notable incidents include graffiti on both the building and a fire hydrant in late 2023, and several reports of abandoned debris on the sidewalk, including a refrigerator and mattress in mid-2024. The most recent permit activity relates to street space usage, with several such permits being issued between 2014 and 2015, typically associated with ongoing maintenance or improvement work. While the building has undergone significant structural and aesthetic improvements over the years, the recent pattern of graffiti and street cleanliness issues suggests ongoing challenges with property maintenance in the immediate vicinity.
