431 23rd Ave, San Francisco, CA 94121

The 4-unit, 2-story multi-family residential building at 431 23rd Ave in the Central Richmond was built in 1972 and is currently owned by the Seto Bruce & Cynthia Trust. The building has undergone several significant maintenance and improvement works, most notably in 2012 when Unit #2 received substantial upgrades including bathroom renovation with tub replacement, kitchen improvements, and electrical updates to both kitchen and bathroom hoods, with a total investment of approximately $2,500. The property has experienced multiple compliance challenges, particularly evident during routine housing inspections in 2000, 2007, and 2015.

Notable violations included fire safety issues such as combustible storage concerns, egress obstructions, and smoke enclosure door problems, though all these violations were eventually abated, with the most recent resolution occurring in December 2016 for unit 3's broken doorbells. A 2015 inspection also designated the property as a nuisance under San Francisco Housing Code. The building's history shows consistent attention to maintenance and code compliance, with inspections indicating both proactive management and occasional lapses in fire safety protocol adherence.

The most recent fire incident recorded was a 730 system malfunction with no civilian injuries. While there have been numerous 311 calls regarding the property's exterior environment, most of these concerns relate to sidewalk parking violations and street cleaning matters rather than building-specific issues. Recent maintenance activity includes addressing various street defects in 2018 and multiple parking enforcement responses, though these are external to the building itself. The property's documented history shows a pattern of periodic inspections and necessary repairs, with no current active building violations or health code concerns as of October 2023.
