422 27th Ave, San Francisco, CA 94121

The two-unit residential building at 422 27th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1923, currently owned by Yeung Mei Ngan.

The building's documented history shows relatively minimal issues over time, with the most significant renovation occurring in 1999 when two storage rooms were remodeled to add a toilet and a window, a project that was completed successfully. A sanitation-related complaint was filed in August 2007 regarding ceramic tiles being improperly disposed of in the backyard, though this issue was resolved within one month by September 2007 and the case is no longer active.

More recent incidents include two complaints in the last five years: in August 2024, there was a report of abandoned furniture that was addressed and resolved by Recology, and in January 2020, there was a parking enforcement request regarding sidewalk obstructions, though the responding officer was unable to locate the violation. The building's record shows relatively few violations or complaints relative to its age and size, with all documented issues being resolved in a timely manner.
