470-472 33rd Ave, San Francisco, CA 94121

The property at 470-472 33rd Avenue in San Francisco's Outer Richmond neighborhood is a duplex residential building constructed in 1923, currently owned by the Xie/Huang Family Trust. The two-unit building underwent significant renovations between 2012-2013, with major improvements including the conversion of existing floor space into a new dwelling unit with kitchen and bathroom facilities, along with a 54-square-foot rear addition and deck expansion. These renovations were accompanied by comprehensive updates to both units including new electrical systems with 200-amp service, plumbing improvements including new bathrooms and kitchens, and HVAC system updates with a new furnace and heat ducts.

The 2012-2013 renovation period also saw the installation of multiple safety features including smoke detectors. Prior to the major renovations, the building had undergone several smaller improvements in the 1980s and 1990s, including window installations and an attempted vertical addition in 1990. The property has maintained its basic maintenance requirements, as evidenced by sidewalk repair work in 2005.

In recent years, there have been several incidents of driveway blocking requiring parking enforcement intervention in 2022 and 2023, though these are typical urban occurrences and not directly related to building conditions. The surrounding area has experienced occasional street cleaning needs, particularly in 2012 when multiple reports were filed regarding loose garbage and encampment items, though these were external to the building itself. The most recent planning records indicate historical attempts to add a story to the building and address street tree requirements, though these issues appear to have been resolved.
