926-930 Vallejo St, San Francisco, CA 94133

The three-unit residential building at 926-930 Vallejo Street in Russian Hill, owned by the Tom Chau Hung Wong Revocable Trust, has a documented history of structural maintenance and compliance issues spanning several decades. Built in 1911, this three-story flats and duplex structure has undergone multiple repair projects, most notably addressing recurring dry rot issues with rear stairs in 2015-2016, completed through several permits totaling $9,000, and the installation of a significant $45,000 reinforced concrete landscaping "sister wall" in 2015.

The building experienced serious concerns between 2014-2019 regarding hillside subsidence, leading to violation proceedings and requiring both structural and safety inspections, though these issues were ultimately resolved through compliance as of April 2019. More recent activity includes several permit revisions and inspections in 2023, particularly focusing on previously completed work from 2016, indicating ongoing attention to building maintenance and compliance.

The property has maintained an active response to various municipal service calls in 2022-2024, addressing issues such as sidewalk defects, parking violations, and maintenance concerns. A documented cooking fire incident with no civilian injuries occurred at some point, though the date is unspecified. The building's history shows a pattern of proactive maintenance and compliance, particularly in addressing structural issues, while also revealing periods of significant required inspections and violations that have since been resolved.
