546-548 Vallejo St, San Francisco, CA 94133

The 546-548 Vallejo Street property, located in Telegraph Hill and owned by the Mar/sung Family Trust, is a two-story, three-unit multi-family residential building constructed in 1906, originally featuring a garment factory on the ground floor. The building has undergone significant modernization work between 2017-2018, including the installation of a radiant heat system, comprehensive electrical rewiring with new subpanels and safety features, and extensive plumbing upgrades for multiple bathrooms, kitchens, and laundry facilities.

The property previously had a garage area that was converted from a commercial space, with approved plans for a foundation replacement and garage modifications. Most recently, there is an active emergency response inspection case from January 2025 regarding structural damage to the east side of the garage, front entry stairs, and security gate, following a vehicle collision with the building.

The property has experienced recurring issues with debris and furniture on the street (October-December 2024), as well as some instances of graffiti and parking violations. Multiple street space permits were issued in 2017, and the building underwent various infrastructure improvements including bathroom renovations, heating system updates, and electrical system modernization. The installation of new safety features such as smoke detectors and the conversion from furnace to radiant heat system demonstrates ongoing efforts to improve resident comfort and safety.
