470-472 10th Ave, San Francisco, CA 94118

The Wong Family Trust owns this two-unit, two-story multi-family residential building located at 470-472 10th Avenue in San Francisco's Inner Richmond neighborhood. Built in 1923, this flats and duplex-style property has undergone several significant maintenance and improvement projects over the years. Most recently, in July 2023, bathroom tile repairs and kitchen cabinet refacing were completed, demonstrating ongoing maintenance of the building's interior.

The property has seen substantial structural work, including a roof replacement in 2005 ($6,300), and an attempted foundation underpinning in 2006 ($3,000), though this permit ultimately expired without completion. A notable renovation occurred in 2001-2002 when the ground floor was modified to create additional living space, which initially triggered several building code violations related to safety concerns including lack of fire-rated separation, second exits, and required sprinklers. These violations were ultimately abated by February 2002 through proper legalization of the family room conversion and bathroom relocation at a cost of $25,000.

The building's maintenance history shows regular upkeep, including siding replacement in 2009 and various structural improvements. While there have been some tenant complaints regarding heating issues in 2001 (both related to non-functioning furnaces and no heat), these were resolved promptly. More recent building interactions primarily involve external matters such as street cleaning, illegal postings, and sidewalk maintenance, with the most recent incidents occurring between 2019-2024 relating to graffiti removal, garbage cleaning, and sidewalk defects. The property has been maintained adequately in recent years, with no active housing complaints or violations on record since 2002, and the building permits reflect ongoing maintenance and improvements to various building systems.
