550 23rd Ave, San Francisco, CA 94121

This three-story, two-unit multi-family residential building at 550 23rd Avenue in the Central Richmond neighborhood was constructed in 1992 following the demolition of a single-family dwelling in early 1989. The construction involved several stages, including foundation revisions, exploratory work, and the removal of a rear projection with associated retaining wall construction, all of which were completed by late 1989.

The most recent significant maintenance issue occurred in December 2023, when there was a sewage backup incident involving a catch basin that was subsequently resolved by PUC Sewer Operations. The building's maintenance history shows only one major repair work on record, dating back to 2003, when broken siding was repaired at a cost of $1,000. More recently, there has been a notable pattern of parking violations in the vicinity, with multiple documented cases of vehicles parking on sidewalks between 2019 and 2023, though most of these cases did not result in citations.

The most recent parking-related incident occurred in September 2024 and resulted in a citation. There has also been one documented fire-related incident, which was recorded as a false alarm with no civilian injuries. The property owners, Cynthia Pon and David Chan, have maintained ownership since the building's completion.
