260 Charter Oak Ave, San Francisco, CA 94124

The two-unit residential building at 260 Charter Oak Avenue in the Silver Terrace neighborhood, owned by Yang Shi-bing, has undergone several significant modifications since its construction in 1929. Historical improvements include a horizontal room addition completed in 1987 and the installation of vinyl siding in 1990. More recently, in 2012, the building's electrical system was upgraded to a 120-240V 100-amp service with 7 circuits, representing a significant modernization of the building's infrastructure.

The property has been the subject of various maintenance and safety concerns, most notably a housing complaint filed in December 2011 regarding unauthorized construction of ten rooms with kitchens and bathrooms in the ground floor, along with onsite trash collection facilities. While this complaint was marked as "Not Active," it remains uncertain whether it was fully resolved. The building has experienced recurring issues with graffiti and exterior maintenance in recent months, particularly between October 2024 and January 2025, with multiple reports of graffiti on public infrastructure (poles and sidewalks) and the building's own surfaces.

These incidents have mostly been addressed through the city's graffiti abatement procedures. The property has also had two documented cases of garbage and debris concerns in January 2025, though these were resolved with no work needed or other interventions. A parking enforcement issue regarding a blocked driveway was documented and resolved with a citation in November 2024.
