2343 19th Ave, San Francisco, CA 94116

The two-unit residential building at 2343 19th Avenue in Parkside, owned by Du Bing Hua & Huang Ziqing, has a mixed maintenance history since its 1924 construction as a two-story flats and duplex structure. The most recent major improvement was a bedroom addition on the first floor proposed in September 2018, though the permit showed no associated costs.

Significant past works include a 2018 siding replacement at the back of the building ($3,500) and a substantial electrical upgrade in 2005, which included a new 200-amp panel installation. The building experienced serious maintenance issues in the early 2000s, with multiple housing and safety violations documented in December 2002, including problems with heating, smoke detection, window safety, and ventilation systems, all of which were abated by January 2003. A series of heating-related complaints between late 2002 and 2004 indicated persistent HVAC problems, and there was also an incident of unauthorized bathroom remodeling in December 2003.

More recent records (2016-2024) show primarily external and streetscape issues near the property, including garbage concerns, pavement defects, and some parking enforcement matters, though these are not directly related to building conditions. The only recorded fire-related issue was resolved within a month in late 2019 regarding weeds and grass. The building's documented history suggests that while major building systems like electrical have been upgraded, there may be ongoing maintenance considerations given the age of the structure and the nature of past heating system problems.
