475 33rd Ave, San Francisco, CA 94121

The two-unit, two-story residential building at 475 33rd Avenue in the Outer Richmond, owned by Siu Chun Lee Revocable Trust 2009, has maintained its character as a 1924 flats and duplex structure. The property's documented history reveals several maintenance and infrastructure issues over the years, with the most recent significant incident being a sewage backup in September 2022 that required PUC Sewer Operations intervention and was subsequently resolved.

A more serious maintenance complaint was filed in September 2005 regarding the kitchen and bathroom conditions, specifically mentioning loose floor tiles and mold in the bathroom ceiling, though this issue was marked as abated by June 2006. The building's permit records show minimal activity, with only one street space-related permit issued in October 2012 at an almost negligible cost of $1.00.

More recent street-level maintenance issues have been addressed through standard municipal channels, including the pickup of abandoned Christmas trees in February 2023, general cleaning needs in May 2021, and the resolution of illegal postings in November 2013, though these exterior matters are not directly related to the building's residential conditions. The only recorded fire-related incident was a false alarm or call, with no civilian injuries reported and no specific date documented in the provided data.
