921-925 Jackson St, San Francisco, CA 94133

The three-unit multi-family residential building at 921-925 Jackson Street in Nob Hill, owned by the Won Family Living Trust, is a three-story flats and duplex structure built in 1908. The property has undergone several significant maintenance and improvement projects over the past few decades, with the most recent major work being the replacement of galvanized piping with copper in December 2021. Previous improvements include a garage door widening project in 2002 ($9,500) to increase access from the original dimensions to 9'6", and rear stair repairs due to rotted posts completed in 1999.

The building has experienced three routine safety inspections by Housing Inspection Services (1999, 2004, and 2008) that resulted in various violations, primarily related to fire safety concerns such as fire extinguisher maintenance, smoke enclosure doors, and stair repairs - all of which were subsequently abated, with the most recent inspection in 2008 documenting the need for fire-resistant separation in the laundry area. A conversion of the garage into an apartment was also documented in 2002 and officially completed in 2012. The building's plumbing system was notably updated in 2021 with the replacement of galvanized piping.

Recent activities at the property have primarily involved external issues such as parking enforcement matters, with multiple citations issued for driveway blocking between 2018 and 2024, and a street light maintenance request in 2020. A pavement defect was reported in January 2018, which was traced to a Pacific Bell vault cover issue. The building's permit history shows regular maintenance activity, including a street space permit issued in 2008, though most significant structural work appears to have been completed by 2021. The property's inspection record indicates consistent compliance with safety requirements following initial violations, with no active violations currently on file.
