Augrented Insights Report

The property at 422-424 34th Avenue is a two-story, three-unit multi-family residential building located in San Francisco's Outer Richmond neighborhood, built in 1924 and currently owned by the Au Family Trust. The building has undergone several significant improvements over its lifetime, including the installation of aluminum windows in 1986, vinyl siding in 1997, and a complete rebuild of the second stairs in 2004 to restore it to its original construction.

More recently, two street space permits were obtained in 2008 and 2010. The most pressing concerns for this building emerged in September 2024, when multiple serious violations were documented, including rodent infestation, peeling paint posing potential lead hazard risks, and missing smoke and carbon monoxide detectors.

These violations, along with a tenant complaint detailing significant maintenance issues including mold growth, water intrusion, and window problems, were officially filed on September 12, 2024, with the inspector noting the property as being in a deteriorated condition. While these violations were technically abated by October 24, 2024, the nature of the issues raised significant concerns about the building's maintenance and current habitability conditions. The building's history shows previous work on interior and exterior maintenance, including wall repairs and stair improvements, but the recent cluster of violations suggests potential ongoing maintenance challenges.
