480 3rd Ave, San Francisco, CA 94118

The two-unit residential building at 480 3rd Avenue in San Francisco's Inner Richmond district is a two-story flats and duplex structure built in 1910, currently owned by the Shigematsu Family Living Trust. The property has undergone several significant maintenance and improvement projects over the past several decades, with the most substantial work occurring in 2006 when $20,000 was spent repairing damaged exterior siding in the lightwell area and rear of the building's northeast corner, along with waterproofing improvements that were not visible from the street.

Other notable maintenance includes a garage door replacement in 2013 ($1,870), a sidewalk permit issued in 2009, and a complete reroofing project conducted in 1991. The building's recent history shows minimal resident complaints or safety incidents, with only two parking-related 311 calls recorded in 2021 and 2022.

Both incidents involved issues with vehicles obstructing access, though in each case the responding officers were unable to validate the reported problems. The property's maintenance record suggests regular upkeep by ownership, with no recent major structural or safety concerns documented in public records. The most recent permit activity dates back to 2013, indicating no significant structural modifications or improvements in the past decade, though this alone does not necessarily indicate any maintenance issues.
