701 Silliman St, San Francisco, CA 94134

The three-unit multi-family residential building at 701 Silliman Street in the Portola district has a documented history of structural improvements and maintenance needs since its construction in 1900. The most significant recent work occurred in 2002-2004, when a substantial two-story rear addition was constructed, comprising social rooms, bedrooms, and bathrooms, followed by the addition of exterior stairs and some interior revisions.

Earlier renovations included kitchen and bathroom relocations with deck modifications in 1994, and reroofing work in 1991, all of which were completed through proper permitting processes. Of particular concern are recent maintenance issues related to sewage systems, with multiple reports of sewer backups and discharges in 2024, including two unresolved cases in July 2024 and one that was resolved in December 2024. The building's history includes two complaints regarding possible illegal unit conversions in 2007 and 2010, though these cases were marked as "Not Active" after investigation.

Additionally, there were vegetation management concerns noted in fire complaints in 2006 and 2010, though these were promptly corrected. Recent municipal services calls in 2024 have also addressed various urban maintenance issues, including an overgrown tree, garbage and debris concerns, and some parking-related matters, indicating ongoing property maintenance needs within the surrounding area. The current ownership is listed as held by Mai Wilson Wei Qiang.
