434 23rd Ave, San Francisco, CA 94121

The property at 434 23rd Avenue in the Central Richmond neighborhood is a two-story, four-unit multi-family residential building constructed in 1923, currently owned by the Nancy Y Wong Living Trust. The building's significant historical records show several safety-related violations in 2002 that were promptly addressed, including requirements for smoke enclosure door closers, garbage chute fire sprinklers, removal of combustible storage, and security improvements such as self-closing exterior doors and deadlatch locks. A 2011 routine inspection also noted issues with fire extinguishers that were subsequently resolved.

The building has undergone various maintenance work over the years, including a reroofing project in 1992 and repairs to front stucco damage from vehicle impact in 1990. More recent records from 2016 and 2007 show approved street space and sidewalk permits. Recent activity at the property has primarily consisted of external maintenance issues, particularly concerning street cleanliness and parking violations.

There have been multiple reports of garbage and debris on the street (2024), blocking driveways (2022-2023), and hazardous materials incidents (2020). The building's safety systems have been maintained, with only one recorded malfunction involving a smoke detector activation. The property has maintained a generally positive record since the early 2000s violations were addressed, with no active violations or complaints currently on record.
