733 5th Ave, San Francisco, CA 94118

733 5th Avenue is a two-story, 6-unit multi-family residential building located in San Francisco's Inner Richmond neighborhood. Built in 1964 and currently owned by Mai John Jian Zhen & Mei Yi, the property has experienced several notable events over its history. The building's most significant cluster of issues occurred in 2003-2004, when multiple violations were documented regarding safety systems, including problems with emergency exits, smoke detectors, and the central alarm system.

Water damage in the lobby area was also noted during this period, along with maintenance and safety concerns affecting individual units. These violations were all officially abated by April 15, 2003. Since the mid-2000s, the building has undergone routine safety inspections in 2003 and 2015, with no major violations recorded.

More recent history shows several 311 calls related to the property, primarily concerning parking violations and sidewalk issues, though these are not directly related to the building's condition. In 2017, the property experienced two consecutive sewage backup incidents that were resolved by the Public Utilities Commission. The building has also had several fire alarm activations recorded between 2003 and 2020, all of which were either false alarms or related to system malfunctions, with no injuries reported in any incident. The most recent service-related interaction occurred in January 2024, but this was not directly related to the building's condition or systems.
